CAUTION

INTENDED USE



3 Function description

This section provides an overview of the compensation settings of the PowerAct Active Filter. These settings can

be changed via the touch panel (HMI) or the Web User Interface (WUI). Details on this are provided in a later

section. Please refer to the Overview section in the PowerAct Installation Manual for an overview of the operating

principle.

Before the system can be used, it must be commissioned. This includes setting up the basic and operating

parameters of the system. Commissioning can either be performed via the touch panel or the WUI.

There are three (3) basic compensation modes

Reactive Power Compensation

Load Balancing

Harmonic Compensation

Reactive power compensation

The active filter can be configured for droop or dynamic reactive power compensation.

In static operation, a defined reactive power (Qref—Reactive Power Control) is generated similarly to a fixed

capacitor or choke.

In dynamic operation, the filter regulates its output power of the fundamental oscillation such that a defined power

factor (range) is maintained at the measurement point. The target range can be specified via an upper and lower

limit value of the active power factor (cosφ).

Note: All settings relate only to the fundamental (60Hz) and have no influence on the harmonics. Please note in

comparison measurements that the active power factor (cosφ) in distorted grids does not correspond to the power

factor (λ), because the active power factor (cosφ) does not contain a harmonic component by definition.

Load balancing (LB)

Load balancing is used to balance the asymmetrical current consumption of one or more loads at a network node

defined by the MIO measurement point. The function compensates for the difference of the fundamental

oscillation components of the three-phase currents with each other and thus produces a symmetrical grid load.

The regulation is configured separately for the negative sequence system (asymmetry caused by load between

two conductors) and zero sequence system (asymmetry caused by single-phase loads L against N, 4-wire

systems only):

Balancing ∆: Compensation level as a percentage [%] of the negative sequence system



Through this division into the symmetrical components, the symmetry is restored without any explicit

compensation of reactive power.

Functional notes:

The active and reactive components of the current will always be balanced with the same compensation

level

Prerequisites for zero sequence system compensation are the use of four-wire IPUs with N-connection and a

three-phase load/grid current measurement with the MIO.

Balancing the fundamental oscillation leads to an increased load on the DC link and can therefore lead to the

power limitation (derating) of the system with the message “Derating: DC voltage unbalanced”:

Variable per IPU Derating AC RMS

current 3W

Positive sequence system 125A

Negative sequence system 125A

Zero sequence system NA

Table 2: Derating limit values per IPU

The open/closed loop parameterization has the following effect on the behavior

Open loop: The currents are measured at the load and set at the IPU output

Closed loop: The currents are measured in the grid and regulated at the measurement point

Harmonic Compensation

The function SHC (Selective Harmonic Compensation) compensates for (“filters”) harmonics in the energy supply

grid.

For this, differentiated modes are distinguished for this which achieve both optimized current-based and

optimized voltage-based results for different requirements and grid conditions.

The following modes are available separately and can be individually configured for each harmonic

(3rd to 51st order):

1. Switched off No output

2. To zero Regulates the current output at the system connection point to zero

3. Compensation I Reduces the harmonic current measured at the connection point of the MIO by the

set compensation level (0 ...100%)—with current measurement.

Compensation U Reduces the

harmonic voltage measured at the connection point of the MIO by the set

compensation level (0 ...100%)—without current measurement.



4. 5. U Limit/I-Ctrl Limits the harmonic voltage measured at the connection point of the MIO to the set

maximum value taking the set maximum compensation level (0 … 100% based on

current) into consideration—with current measurement.

U Limit/U-Ctrl Limits the

harmonic voltage measured at the connection point of the MIO to the set maximum

value taking the set maximum compensation level (0 … 100% based on voltage)

into consideration—without current measurement

voltage-based compensation modes.

Modes 4 and 6 do not need an external current transformer. They function exclusively based on the measured

line voltage.

In these modes, the compensation level relates to the reduction of the voltage based on the SIA grid analysis.

0% corresponds to the operating mode “to zero” (no output current at this frequency)

100% regulates to the line voltage only and reduces this to the desired value 0.

NOTICE: It is strongly recommended that modes 4 and 6 NOT BE USED with manual SIA!

NOTICE: The tolerance in terms of the compensation level in these modes can be up to +/-30%. It is therefore

recommended that full compensation (100%) or the combination with Limit U be used as the setting.

Current-Based Compensation Modes

In modes 3 and 5, the compensation level is based on the current. Here, the compensation level describes the

ratio of system output current to grid current at the MIO connection point:

0% corresponds to the operating mode “to zero” (no output current at this frequency)

100% only regulates the grid current and reduces this to the desired value 0.

Limiting compensation modes

In modes 5 and 6, the compensation is only active if the configured voltage limit values are exceeded at the MIO

connection point. The system only supplies enough output necessary to comply with these limits.

In all modes, the compensation level applies in the same way for the positive, negative and zero sequence

systems, and is only specified once per harmonic. Compensation of the zero sequence system is only relevant

for 4-wire systems. The selective regulators for all odd-numbered harmonics of the ordinal numbers 3rd to 51st

operate parallel to each other without functional limitations in a system configuration (up to max. 4x IPUs and 1x

MIO).

With the SIA function (System Identification Algorithm), the system performs an automated grid scan to

determine the frequency response.



4 User Interfaces

There are four different user interfaces:

1. Human Machine Interface (HMI) via touch panel or Web User Interface (WMI)

2. Fieldbus interface (to a superordinate control technology system)

3. Digital inputs and outputs

4. SD card (offline system configuration via the manipulation of text files)—NOTICE: ONLY TO BE USED BY

AUTHORIZED SERVICE PERSONNEL!

Human Machine Interface (HMI)

The touch panel and WUI (Web User Interface) layouts are as effectively identical. The WUI (Java

applet) includes additional functions for data management on the SD card

touch panel.

The system can be configured, commissioned and operated via the touch panel in the front door. It can be used

to easily set parameters, check operating states, and display the measured data and system state during

operation. The touch panel can be used for entering commands and for menu navigation.

Touching the screen in the designated areas will call up, for example, the operating mode, the menu items or

measured values:

WUI — Web User Interface

As an alternative, the system can be operated graphically via a PC. To do so, the respective device

is to be connected to the TCP/IP interface of the control computer and the Java applet called up. The

tabs in the interface also provide access to the SD card contents with copy function to the connected

PC. A site-specific IP address can be assigned at the touch panel.

Anybus Fieldbus Interface

The control computer (CCU) has an integrated Anybus interface. Any approved plug-in modules from the

manufacturer HMS can provide native communications using the Modbus and BACnet protocols.

SD Card

The control computer comes equipped with an SD card. In addition to the programs for operating the system, this

memory card also contains all configured parameters. These can be edited offline via a text editor, e.g., to set the

system configuration parameters (hardware configuration) or to configure general basic settings, e.g., to preset

the parameter sets. Card can be inserted or removed only when the system is deactivated. All parameter settings

via touch panel or Java applet are also stored on the SD card (online).

NOTICE: Parameter changes which are made directly in the text files of the SD card are not checked for

plausibility. Incorrect changes can lead to malfunctions or even to irreversible hardware damage—therefore,

changes may only be made by authorized personnel. The manufacturer’s warranty will become void in the event

of unauthorized manipulation of data on the SD card.

The SD cards approved for use is SanDisk, 16 GB, HC, class 4

Custom alarm messages and warnings

The system contains both hardware and software that continuously monitor the operating states and trigger

alarms or warnings that put the system in a safe, stopped error state or that issue messages to the HMI. Using

the programmable internal digital inputs or outputs, the user can implement remote monitoring.

Acknowledging Alarm Messages

Pending alarms are reported at the HMI. Alarms may be acknowledged. If the cause of an alarm remains a new

alarm is triggered. If an alarm forced the system to standby all alarms must be acknowledged before the system

will allow a restart. It is strongly recommended that the cause of the error be identified before acknowledging an

alarm in order to prevent damage in the system or the installation.

Java application (WUI)

The PowerAct Active Filter can be configured and monitored remotely via Ethernet from a PC web browser with a

valid and current Java installation. System IP address can be assigned and viewed at the touch panel (HMI).

Web version displays the same screen views as those appearing on the touch panel. Note that touch panel

access will be denied if while Java app is active.

System settings and Configuration

Defines the hardware-specific characteristics. Due to the basic nature of these settings, the system must be

RESTARTED after any changes. (Exception: Operator mode)

(HMI) System > Grid

• Nominal voltage: e.g., 480 V Nominal frequency: 50 Hz/60 Hz

• Grid configuration: IT/TN

• Control topology: Closed loop/open loop



• Level THDv for shutdown: e.g., starting from 20% Telecontrol frequency in Hz

(HMI) System > DSC Port Configuration:

Enter the number of modules (IPUs) and the number of connected measurement modules (MIOs).

One CCU (controller) can operate and connect

• up to 4 connected IPUs

• as well as up to 2 MIOs at the same time.

(HMI) System > Operator Mode

Select between

• Local access => operation via HMI/touch screen. No commands via Modbus are accepted

• Remote access => operation via PLC. No commands from the HMI (touch screen/Java) are

accepted.

7.1 Control modes

There are three control modes available which can be operated in parallel:

(HMI) Control > Basic Setting > Mode > Parameter Set.

The following are available as the control basic settings:

• Reactive power control

• Balancing

• Harmonic compensation

For each control function, a mode, a priority, a dynamic and a rate of change can be selected via the HMI.

The settings are only valid for the respective parameter set (there are eight parameter sets). You can switch

between the parameter sets via the HMI (tapping at top left).

Control Modes Priority

If more than one control mode is active, the system may reach its power limit before control targets have been

reached. If all active control modes have the same priority, these will all be derated in the same way if the power

limit is reached. Control modes can be assigned priorities (1 – 4) with the control mode with the highest priority

derated last. The difference between the priorities of two control modes may not be greater than 1.

Dynamic

This describes the response speed of the system to changing grid states. The dynamic is configured in seconds

and specifies the time constant tau. In ideal conditions, the desired control value reaches 95% of its target value

within a period of 3x tau. Here, 0.1 s is recommended as the standard parameter value. An exception to this is the

dynamic of the reactive power voltage regulation. Here, unitless parameters are used.

For the dynamic, the rule is as fast as necessary, as large as possible. A high dynamic reduces the stability and

accuracy.



The dynamic for the voltage regulation is not specified in “seconds.” In the case of voltage regulation, the grid

impedance has an influence on the control dynamics. For this reason, the dynamic cannot be specified as a time

constant here.

The recommended dynamic for voltage regulation is unitless and is 0.001. Because the reactive power modes

Qref/Cos (phi)/Vref cannot work in parallel, there is only one dynamic parameter. If the reactive power control

mode is changed, it is necessary to check the dynamic parameter and to adjust it if required.

Change Rate

This is the rate of change when changing the desired value in pu/s. The standard parameter value is “0”—> the

change rate is disabled. This means that the system responds to a desired value change with the control dynamic.

Example: Parameter set to 1 pu/s: the system responds to a desired value change with a maximum rate of

increase of 1 pu/s.

7.2 Reactive power Settings

• Function for feeding in constant reactive power Qref

The Q function feeds in symmetrical reactive power at the connection point highly dynamically in accordance with

the desired value specification.

(HMI) Control > Control Q > Menu overview

All reactive power influences on the grid are done at the fundamental frequency (60 Hz)

The control variable is the imaginary part of the current (+/-90 °) in relation to the line voltage.

• cos (phi) (PFC control)

• Reactive power (Qref control—Q Reference)

• Voltage level (Vref control—V Reference)

(HMI) Control > Control Q > Qref

The Qref function regulates the symmetrical reactive power at the IPU AC connection in accordance with the

desired value specification, whereby this information is specified in kvar inductive (load sign convention).

The change rate for changing the desired value is configured in the basic settings.

• Function for dynamic reactive power compensation PFC Power Factor Correction

(HMI) Control > Control Q > PFC

The function PFC keeps the power factor at the measurement point (mean value over three phases) in a band

between two configurable limit values.



The limit values are stored on the SD card (negative sign for capacitive and positive sign for inductive

compensation). Eight different parameter sets are available for selection for the online configuration.

In order to enable the parallel operation of distributed systems, a droop is also specified.

Note on compliance with the limit values: The limit values are site-specific and adjusted according to the load

case. Here, it is not ensured that cos (phi) is permanently kept within this band under all circumstances. Instances

with very low active power, cos (phi) can temporarily leave the band.

Figure 7.1: Power Factor Correction operating principle

Function for dynamic voltage regulation Vref Voltage regulation Vref

(HMI) Control > Control Q > Vref.

Voltage reference control:

This function is used to maintain line voltage stability. It feeds in reactive power based on the line voltage in

accordance with the configurable VI characteristic curve.

Within the dead band between values 1 and 2, the voltage is not manipulated. If the line voltage leaves the dead

band, reactive power is fed in based on the slope (droop) of the VI characteristic curve that can be configured

separately for overvoltage and undervoltage.

Here, the system output current is regulated based on the line voltage.

The VI characteristic curve is configured using the following parameters:

Reference 1 voltage: Lower desired value of the voltage [in pu]

Reference 2 voltage: Upper desired value of the voltage [in pu]



Droop capacitive: VI characteristic curve increase below desired value 1

Droop inductive: VI characteristic curve increase above desired value 2

The droop is the result of the ratio dV/dI. It is to be adapted to individual grid conditions.

Note:

1.0 pu of the voltage V equates to the grid rated voltage

pu of the current I equates to the system rated current

Figure 7.2: Vref operating principle

NOTE: The dynamic for the voltage regulation is not specified in “seconds.” In the case of voltage regulation, the

grid impedance has an influence on the control dynamics. For this reason, the dynamic cannot be specified as a

time constant here. See Control => Basic Settings.

7.3 Load Balancing

(HMI) Control > Load Balancing

The balancing function compensates for the difference of the fundamental (60 Hz) component of the three-phase

currents producing a symmetrical grid load at the measurement point.

The regulation can be configured separately for negative sequence system compensation (systems with three-

and four-wire connection) and zero sequence system compensation (only systems with four-wire connection).



7.4 Harmonic compensation

The system compensates harmonics up to the 51st harmonic.

(HMI) Control > Harmonics > Harmonics

The following settings can be configured for each harmonic individually:

Mode: Off, To zero, Compensation I, Compensation U, Limit U/Control I, Limit U/Control U

7.5 System Identification Algorithm (SIA) Harmonic Correction

The System Identification Algorithm (SIA) determines the grid-dependent harmonic corrections. To this end, the

transfer function to the measuring device is determined. The amplitude of the scanning signal can be configured.

For safety reasons, a limit value for the maximum permissible SIA voltage distortion is also configured in parallel

with the amplitude limit value.



Triggering the SIA

Automatic correction determination is triggered by:

1. The system being restarted (if the Boolean parameter DoSiaAfterBoot is set in the settings.txt file)

2. Manual triggering via button

3. External triggering via fieldbus interface

4. Automatic triggering in the event of resonance detection (violation of the limit value HarmonicDistortion level

UTrip for a harmonic)

The number of times the SIA is triggered in a time interval is monitored. This time interval can be configured.

Both manual SIA trigger commands and automatic control triggers are counted. If the permissible number of SIA

triggers per time interval is exceeded, retriggering the SIA is not permitted. The counter is automatically reset

once the time interval elapses or via a manual acknowledgment.

Persistent storage of data collected by SIA

The data collected by the SIA is stored permanently on the SD card and is also available after a restart of the

system.

Mode:

Mode of the harmonic compensation.

“ACF to zero”: Output of the ACF is compensated for.

“Compensation”: MIO measurement point is compensated.

“ULimit”: The ACF only begins compensation once the harmonic limit value ULimit has been exceeded.

Phase correction: manual

Correction angle for the controller to adjust the specific frequency to a phase offset between the measuring signal

and the output of the filter (step response of the grid) caused by mains impedance.

Phase iExt/iInt:

Phase correction angle of the internal system model [in °]. Only the automatically determined values are

displayed.

UTrip:

Monitoring limit value of the individual harmonic voltage distortions.

Trigger:

Manual triggering of the SIA for correction angle determination.

NOTE: The commissioning engineer must be aware that with manual triggering the SIA, the harmonic

compensation mode must also be set to “automatic” to ensure that the determined values are also used by the

regulator. If the harmonics compensation mode is set to manual, the manually specified phase correction angles

will be used.

Resonance Monitoring

(HMI) Control > Harmonic Expert

The line voltage level of all harmonics up to the 51st harmonic are continuously monitored to detect and prevent

the excitation of resonances in the grid. The limit values for triggering automatic resonance suppression can be

adapted to the local conditions manually.

The default values are based on EN50160 and are set to 2% above the permissible limit values in accordance

with this standard:

Table7.1: Default parameter values for harmonics monitoring

NOTE: When setting the UTrip and ULimit parameters on the HMI, it must be ensured that the UTrip parameter

values are always higher than the ULimit parameter values.

Automated reaction of the harmonic control to a resonance

If a resonance is detected, the System Identification Algorithm is automatically started if the phase correction is

set to “Automatic.” If this sequence exceeds the maximum permissible number of triggers the harmonic causing

the triggering is deactivated.

Automatic warning with the message, “Suspect.”

The resonance monitoring system includes the function of automatically disabling individual harmonics after

several error events. After a single resonance detection, a warning is first issued to the HMI by marking the

corresponding harmonics as “suspect” (yellow exclamation point) but compensation will not be disabled.

Automatic blocking with the message “Critical”

If a resonance event occurs several times in succession, the status of the harmonics is changed from “suspect”

to “critical” (red exclamation point) and compensation will be disabled.

The status “critical” is reset by deactivating the affected harmonics (status to “deactivated”) or by restarting the

system. The access level is visualized via a “padlock symbol” to the right of the harmonics on the screens. After

restarting the system, all harmonic control warnings and disabling actions are reset.

The “critical” status is reset via a mode change of the respective harmonics to “deactivated” and then resetting to

“to zero,” “Compensation,” or “ULimit.”



Manual blocking

When setting the parameters for harmonic compensation, the administrator can specify access rights, and

therefore disable access to setting the parameters of individual harmonics for the “user” user level. See figure

“Harmonics” and “Harmonics Expert.” When logged in as an administrator, harmonics disabled for the user are

displayed in red, and harmonics accessible to the user are highlighted in green.

7.6 DC voltage regulation—DC link

Configuration and operation:

DC voltage regulation can be operated in 4 control modes:

0: = Disable

1: = Constant value regulation

2: = Variable regulation with specification of a maximum limit value (This function is only available for the 3W

configuration).

3: = Manual desired value set by the user

The parameter can be set on the SD card or via fieldbus interface.

Control Mode 0: Disable

The DC link voltage is not regulated.

Control Mode 1: Constant value regulation of the DC link voltage.

Depending on the set grid rated voltage, the DC link voltage is calculated automatically in the system.

The system regulates the DC link voltage to the following nominal values without an adjustment regulator:

Grid rated voltage [V] DC rated voltage [V] maxdcvoltage_V value range

<440 800 600 V - 1350 V

[440 528] 950 950 V - 1350 V

>528 1300 1300 V - 1350 V

Table 7.2: DC link desired value dependent on the grid rated voltage

In this mode, the DC voltage can no longer be influenced via parameterization.

Control Mode 2: Dynamic DC link voltage adjustment

Variable regulation with specification of a maximum limit value (This function is only available for the 3W

configuration).

If the following requirements are met:



Reduction of losses

High compensation current in level and frequency

Operation at high peak grid voltage

The level of the DC link voltage can be adjusted variably.

Behavior: If the set UDC Max of the DC link voltage is reached, the system power is derated. Derating is signaled

via a message. There are no error messages or a shutdown.

In the event of incorrect parameterization of maxDcVoltageInVolt outside of the limits: 800 V - 1,350 V, a warning

message is issued on the HMI.

In the event of incorrect parameterization of maxDcVoltageInVolt within the limits: 800 V - 1,350 V, e.g.,

maxDcVoltageInVolt is below the rated-voltage dependent MinDC voltage, an automatic adjustment of the limit

value is carried out internally without a warning message being issued on the HMI.

• Control Mode 3: Desired value regulation

As the target variable, the desired value is specified in V on the SD card (or via the fieldbus interface).

Parameterization

The following parameters are located in the parameter sets and are used to set the DC link regulation:

generalSettings. autoFunction. dcVoltageControlMode

generalSettings. autoFunction. setpointInVolt

NOTE: When using a DC/DC actuator on the DC link, the DC voltage regulation function of the AC/DC converter

is also to be disabled.

8 Network configuration

Fieldbus configuration

(HMI) System > Interface > Network

The standard settings for the network are preset. The TCP/IP settings can be changed here.

(HMI) System > Interfaces > Serial (CCU)

The standard settings for the interfaces are already preset.

This is intended for internal communication.

If the RS485 parameters are changed on the CCU, the settings must also be configured on the touch screen to

ensure correct functioning. If the transmission paths are long or the electrical noise levels high on the

communication line between CCU and HMI, it is possible to achieve increased communication stability through



reconfiguration, e.g., by reducing the communication speed.

9 Information on complying with grid connection rules

FRT function

The FRT function is deactivated in the default parameter configuration, and switches to the error state if an

under- or overvoltage is present.

Monitoring and protection system

The system has an integrated monitoring and protection system. It contains both hardware and software

functions that continuously monitor the operating status and trigger alarms or warnings that, where necessary,

put the system in a safe stop state and that issue messages to the HMI. By combining the programmable internal

inputs or outputs, the user can implement remote monitoring. In the event of an alarm, the alarm output is

activated. The pending errors can be read off and acknowledged via the fieldbus or HMI.

Protection—External Monitoring

Physical variables such as voltages, currents and temperatures are monitored within the system. The limit values

are listed in the corresponding document. In addition, software monitoring functions are implemented, such as

watchdogs, runtime checks and communication checks.

Protection—System response to errors

The response of the system to the triggering of a protection function is divided into three cases:

1. Information for the user:

The device does not respond because the event is not safe relevant, rather is merely information for the

user. This includes information and warnings.

2. Derating:

A physical variable reaches the first limit value => the output power is reduced. A message is issued

simultaneously whenever the output power is reduced. Furthermore, the derating factor is displayed on the

home screen in place of the utilization.

Example: IGBT temperature too high => the system derates the output power, bringing the entire system to

a thermally uncritical and stable operating point.

3. Disconnection:

If derating was not successful, or if safety-relevant limit values have been violated, the device disconnects

immediately. A trip occurs and an error message is issued.

IPU Redundancy

If just one IPU is affected due to an error, only this unit disconnects if the redundancy mode is active. Otherwise

the entire system switches to the error state.



Protection Derating (reduced output)

The derating function protects the system against damage by reducing its output.

Table 9.1: Overview of derating limit values

In the case of fundamental frequency (50/60 Hz) processes, the system power is reduced directly by reducing

the current limit. The harmonics are reduced indirectly by reducing the measured load. The individual limit values

from which derating begins are hardware-dependent.

Protection—Disconnection/trip and Information

In the event of a violation of a system-critical parameter in the software or firmware, or in system-critical software

statuses, e.g., breakdown of communication to an IPU, a trip occurs:

• The system stops the function, the main contactor is opened

• The system switches to the error state. The error is displayed on the HMI and recorded in the error list.

• Errors and warnings are also transmitted via fieldbus

The error messages are displayed on the HMI in two ways:



1. Error code

2. Text message

The error code is issued as an 8-digit code on the HMI:

Pre-heating function for IPUs with output derating to zero

In order to preheat the IGBTs at temperatures below the minimum value, an automated function is implemented

in such cases that first put the IGBTs into operation without current output (100% derating). This state is

maintained until the minimum temperature at the IGBTs is reached. A corresponding message is shown on the

display:

Protection—Error Handling

After the occurrence of an error event, an ERR.bin error record is written to the SD card and an entry is also

made in the ERROR.txt file on the SD card. In the case of fieldbus connection, the error ID is also specified.

Depending on how the auto functions have been configured; further handling is performed in the system:

1. No handling

Waiting for user action

2. Auto-restart

After the error state disappears, the error is automatically acknowledged, and the system restarts after a

defined time. The number of permitted auto-restarts can be set in the file Settings.txt, see below

3. Auto-configuration.

The resonance handling activates a function which, after error triggering, performs a reconfiguration of the

phase angles of the harmonic compensation via SIA.

4. Disabling

Ultimately, a function can also be disabled

Protection—Manual acknowledgment of alarm messages

Pending alarms are displayed on the HMI (header, center). They can be called up and acknowledged by tapping

this area.

If the cause of the alarm remains after acknowledgment, a new alarm is triggered. All alarms must be

acknowledged before operation is possible again. Via fieldbus, acknowledgment is performed via the

Acknowledge bit (only rising edges are evaluated).

NOTE: It is strongly recommended that the causes of the error are identified before they are acknowledged in



order to avoid damage in the system or the surrounding installation.

Protection—Access rights

The operating concept grants the following access rights:

Protection level Access right

1. Firmware Development (Internal), Technology Partners

2. Software Development (internal)

3. SD card Development (internal), experts (Service, OEM)

4. HMI administrator/Service Experts (Service, OEM), trained specialists (external)

5. HMI user Operators (e.g., electricians without specific knowledge)

6. HMI no login No access rights, display only

Table 9.6: Access hierarchy

Protection—HMI

Access to the system is protected by a three-stage access level:

User level Rights and obligations

Administrator (Service) • Can view settings and measured values. • Can also configure settings that • may impair the safety/function of the system. • Can access the file system on the SD card

remotely via Java applet.

User • Can view settings and measured values. • Can configure settings that are not • reserved for Service.

Display • Can only view settings and measured values.

• Cannot configure any additional settings.

Table 9.7: User level and assigned rights

The security settings are saved on the SD card under “/CONFIGS/Security.txt.” If this file is deleted, the PIN will

be reset to 0000 (or 4321 for Service). Furthermore, the control check is disabled, i.e., anyone can change

settings immediately. The PIN entry for users is red, the PIN entry for administrators (Service) is blue:

For the regulation of the individual functions, a time constant can be set. This enables project-specific interactions with other systems combined with dynamic

requirements to be taken into account. The change rate of the reference values is another setting option. This means that in the event of a reference value jump,

the slew rate is limited internally. A value of zero deactivates the limitation.
