The SIMATIC IPC427C excels in the following characteristics:

Real-time capability through real-time extension (RTX)

RT (Real-Time) and IRT (Isochronous-Real-Time) capability

Open User Communication with PROFINET under TCP/UDP

High ruggedness

Data remanence

Compact design Maintenance-free

Protective mechanism for Compact Flash memory cards

Readily pre-installed for control tasks with WinAC RTX

Real-time capability: Definition

Real-time capability is the ability of a system always to be ready to process produced data. Processing has to be performed within a defined time span.

Real-time systems contain data and events, processes both and performs timely actions. Programs that are in interaction with external systems are executed. If the time conditions are not switched on, an error occurrs. This is treated like a logistic error.

You can indicate what the priority the control program has as compared to the Windows applications running in parallel.

RT and IRT communication

The Real-Time (RT) communication is the basis for the data exchange at PROFINET IO in the area of the decentralized periphery. The transfer of time-critical data takes place in guaranteed time intervals. It is possible to precisely determine the time of transfer. The smooth communication in same network via other standard protocols is ensured.

Isochronous-Real-Time (IRT) is a transmission mode where part of the transmission time is reserved for the cyclic data transmission. The communication cycle is divided in a deterministic part and in an open part. The cyclic IRT messages are sent in a deterministic channel whereas the TCP/IP and RT messages are sent in an open channel. In this way, both data transmissions exist side by side without disturbing each other.

The difference to Real-Time communication is mainly the determinism, so that the beginning of a bus cycle is observed with high precision. The start of a bus cycle may differ by a max. of 1 µs (Jitter).

Open User Communication

The Open User Communication permits open communication of WinAC RTX 2010 through TCP, UDP and ISOonTCP. This makes open data exchange with any communication partner through the PROFINET interface possible.

Ruggedness

The device is highly EMC-proof due to an all-metal housing and a potential-isolated power supply.

Furthermore, the thermal load of the SIMATIC IPC427C is reduced by means of a large heat dissipator and low supply voltage of the semiconductor components.

The mechanically stable structure and missing of mechanically moved parts (when using a compact flash memory card) ensure resistance of the SIMATIC IPC427C against shocks and vibrations.

Data retentivity: Basics

Data retentivity means that the current values of variables in the controller (e.g. process values) are maintained even after a voltage drop during a warm start. Examples for retentive variables:

Flag

Counter

Times

Data blocks

During a cold start, all variables are deleted.

Which variables are retentive can be configured in STEP 7. Further description can be found in the handbook of the WinAC RTX.

Retentivity types for the SIMATIC IPC427C

The SIMATIC IPC427C offers two versions for retentive data backup.

It is possible either to store the data in the file system (i.e. on hard disk or on a compact flash memory card) or to store them in a non-volatile memory area. For IPC427C, this is a battery-buffered static RAM (SRAM). How to determine the storage type will be explained in a later chapter.

Retentivity by means of the file system

If you decided to store the data in the file system, the retentive data are stored in a file at the RUN – STOP transition. At the STOP – RUN transition with warm start, the retentive data are restored from this file.

In case of a power failure, the data are not stored. If nevertheless data retentivity is required, an uninterruptible power supply (UPS) has to be interconnected.

Advantages:

– No buffer battery required

– Quantity frameworks for retentive data are only limited by the size of the hard disk / compact flash memory card

Disadvantages:

– No data retentivity in case of power failure (or: UPS required)

– No data retentivity in case of blue screen (Windows system failure)

Retentivity by means of SRAM

If you decided to store the data in the SRAM, the retentive data are stored in a specifically provided memory area at the RUN – STOP transition. At the STOP – RUN transition with warm start, the retentive data are restored from there. This also works in case of a power failure.

Advantages:

– Retentivity even in case of power failure

– No UPS required

– Data retentivity even in case of blue screen (Windows system failure)

Disadvantages:

– Buffer battery required

Maintenance-free

If a hard disk can be renounced, no movable parts requiring maintenance are contained in the IPC427C. Only the battery has to be replaced.

Protective mechanism for compact flash memory cards

For protection against unauthorized modifications of the system, the Microbox 420-RTX offers the possibility of providing drives with a write protection. This is possible by means of the so-called "Enhanced Write Filter" which is described in detail in the following chapter.

Readily pre-installed for control tasks with WinAC RTX

The SIMATIC IPC427C-RTX (Bundle Version) is delivered ready to be switched on. Both the operating system Windows Embedded Standard 2009 and WinAC RTX are installed and pre-configured. The IPC427C can be put into operation very quickly.


The Enhanced Write Filter (EWF) is a procedure allowing to redirect write processes onto a data carrier in a specific area (overlay). Thus, the data carrier is protected against write access. The EWF is a component of Microsoft Windows XP Embedded.

Characteristics with the EWF being activated

The data carrier is protected against write access.

Write processes are redirected to a specific area (overlay).

Write processes explicitly can be stored permanently.

The modifications can be cancelled by switching off the IPC427C.

No unwanted modifications of system data or applications

Protection against unwanted computer viruses

Note In this application example, the EWF is only described in its RAM (Reg) mode. For further information on the EWF, refer to the following entry ID: 20012701 and to Microsoft Support.

http://support.automation.siemens.com/WW/llisapi.dll?query=20012701&func=cslib.cssearch&content=skm%2Fmain.asp&lang=en&siteid=csius&objaction=cssearch&searchinprim=&nodeid99=�

EWF in RAM (Reg) mode

EWF settings are stored in the registry.

Overlay is set up in the RAM and will be lost after restart.

The division of the storage medium into partitions is independent of the EWF.

The EWF settings of the loaded operating system apply.

Protective mechanism for compact flash memory cards

For compact flash memory cards, the manufacturer guarantees a limited number of write and delete cycles. If this number is exceeded, the functioning of the memory is no longer guaranteed. Therefore, it is recommended to reduce write and delete cycles on the memory card to the minimum.

Note The EWF is disabled in Windows Embedded Standard 2009 by default.

Activate the EWF after having set up the Microbox 420-RTX.

If the EWF is activated, the station is locked in the Station Configuration Editor. To cancel a locking of the station, deactivate the EWF and release the station manually in the Station Configuration Editor.

Recommended settings of the Enhanced Write Filter

In delivery state, the compact flash memory card of the SIMATIC IPC427C is divided into two partitions: A system partition "C:\" and an extended partition "D:\". Activate the EWF for the "C:\" partition while using the "D:\" partition for permanent storage of data.

In the course of this document, it is assumed that recommended settings of the EWF have been made.

Note If you want to activate the EWF also for partition "D:\", observe the activation order. First activate the EWF for partition "D:\" and then for partition "C:\". For deactivation, proceed in the reverse order.

The reason for this is that the EWF settings are stored in the registry. If the registry is located on partition "C:\", the EWF must be deactivated for partition "C:\" first.

Commands of the EWF

You can enter commands for the EWF by means of the command prompt. The command syntax of the EWF is "ewfmgr [<drive letter> ] [Options]", e.g. "ewfmgr c: -enable". In the following, some commands are described in a table.

6 DiagMonitor SIMATIC DiagMonitor is intended for monitoring the status of a SIMATIC PC (e.g. fan speed). In this application example, DiagMonitor (version 4.2) is used for monitoring the IPC427C in order to allow the controller (WinAC station) to respond to system states such as alarms.

6.1 Installing DiagMonitor

Installing DiagMonitor

In the delivery state the SIMATIC DiagBase application is installed on the IPC427C. This application must be uninstalled prior to installing the DiagMonitor.

In this application example, DiagMonitor has to be installed on the SIMATIC IPC427C (for further information on remote control by means of DiagMonitor, refer to the manual on the CD). Execute the installation file and follow the instructions of the installation program. You are asked to perform a restart.

Uninstalling DiagMonitor

Uninstalling DiagMonitor is done according to the Windows standard.

6.2 Configuring WinAC for data transmission

To use data of DiagMonitor in WinAC RTX, configure the WinAC station in your project. Make the following modifications in the controller:

Create a data block for data of DiagMonitor.

Establish a connection to the OPC server.

Creating a data block for data transmission in WinAC

The data block can be copied from the S7 example project of DiagMonitor (or with another name). The data block "DB111" in this application originates from the example project of DiagMonitor and describes the data structure.

The example project of DiagMonitor is located in the installation directory of DiagMonitor. Open the “OPCSamples” subdirectory Here, you will find the S7 example project "DMV4OPCWinLC44.zip". Retrieve the example project in the SIMATIC Manager. For further information, refer to the "readmeWinAC.txt" file in the directory.

Connecting WinAC to OPC server

Configure your WinAC station for a connection to the OPC Server. A detailed description can be found in the “WinAC RTX 2010 handbook”.

Here you will learn …

more on the functionality of the STEP 7 sample program

the assignment of the input and outputs on the distributed I/O

how you operate the sample program

Note This chapter does not include an extensive program description. This application does not focus on the S7 program; it focuses on the configuration of WinAC RTX as well as on the process interface via distributed I/O.

Functionality of the S7 program

The S7 program from the example project is used to control a virtual mixing and bottling plant. This plant consists of:

A boiler with two inlet valves and one outlet valve

a mixer for the boiler

a heater as well as a cooler for the liquid in the boiler

The user has the possibility of influencing the mixing process by selecting different recipe data records.

Input and output assignment

The S7 program is operated via digital inputs. Connect an “ET 200S” periphery with the SIMATIC IPC427C through the desired communication channel. Make sure the distributed I/O and the power module is supplied with power. For further information, refer to the "Distributed I/O System ET 200S – Operating Manual" manual under the following entry ID: 1144348

Connect a switch each to the inputs E 0.0, E 0.1, E 0.2 of the periphery (ET 200S). The actual process is controlled via digital outputs. The assignment of inputs and outputs is listed in the following table.

7.1 Installing the example program

In this chapter, you will learn how to install the example program

Loading the STEP 7 project

The STEP 7 project is available in archived form. It has to be loaded in the WinAC RTX.

Note The WinAC RTX V4.6 has to be included in the hardware catalog of the STEP 7 software. This is only possible from STEP 7 V5.5 onwards.

Table 7-2

No. Instructions

1. In the previously extracted "S7Proj“ folder of this application, you will find the 23942303_WinAC_SE_CODE_v20.zip file. This is the archived STEP 7 project. Open STEP 7 and retrieve this archive via "File Retrieve". Open the project.

2. Connect the IPC427C and the PG to a network (e.g. connect both devices through an Ethernet cable and adjust the IP addresses, as described in chapter 4.2).

3. Check the “Station Configuration Editor”. Make sure that the station name in the configuration matches the station name in the station configuration editor of your IPC427C. If necessary, adjust it accordingly. Further information in chapter 4.3.

4. Set the PG/PC interface of your PG to TCP/IP(Ethernet).

5. Load the project from STEP 7 into the WinAC on the Microbox 420-RTX.

Once you have loaded your STEP 7 project, now determine the boot-up behavior of the WinAC RTX. When setting up the “boot-up behavior”, two properties need to be taken into account.

Boot-up behavior (e.g. warm start, cold start) of the WinAC RTX which is defined in the hardware configuration of the STEP 7 project. Here, the same settings have to be made as for other SIMATIC S7 CPUs.

Automatic start of the WinAC RTX controller on a PC (e.g. on the SIMATIC IPC427C). For this purpose, the functions “Controller for start when booting PC” and “Autostart” are provided in the “CPU” menu of the WinAC RTX.

Start behavior of the WinAC RTX

If the WinLC RTX operator panel is to start automatically once the computer has been booted, enable the “Start controller at PC boot” option in the properties.

After the restart or after a power failure of the IPC427C, the WinAC RTX is automatically started and changes to the “STOP” mode, even if the “RUN” mode was set up before.

If you would like to set up the WinLC RTX so that it starts in the same mode after a restart in which it was previously, than you have to additionally enable the “Autostart CPU” function.

Changing the start behavior

By enabling the "Autostart" function, WinAC RTX starts in the same operating mode as it was before shutting down the controller. The same is the case for a reboot or a restart of the IPC427C.

This means:

if the controller was in the “RUN” mode when it was closed the controller will start in the “RUN” mode.

if the controller was in the “STOP” mode when it was closed the controller will start in the “STOP” mode.

Enable the “Autostart” function as follows:

Table 7-3

No. Action

1. Open the “WinLC Properties” dialog with the WinAC RTX menu command “CPU Properties…”.

2. Make the desired changes. By clicking “OK” you close the dialog

8 Restoring the System A PC system which has been set up (e.g. SIMATIC IPC427C) can be backed up by means of a specific program (e.g. " SIMATIC IPC Image & Partition Creator V3.1"). In this case, the status of the system can be reset. This might be helpful in the following cases:

Restoring the delivery state of the SIMATIC IPC427C

System is no longer stable

Resetting modifications of the system since the last backup

This chapter describes how to restore the delivery state of the SIMATIC IPC427C by means of a restore CD. For further information, refer to the following entry ID: 42794491

ATTENTION After restoring the system, the delivery state of the operating system of your SIMATIC IPC427C and of the programs will be restored. All modifications and settings made by you will get lost.

BIOS settings remain unchanged after restoring the system.

Restore CD

The Restore CD is available via Technical Support. The restore CD is bootable. Also read the "readme.txt" file on the restore CD.

Booting up the Microbox 420-RTX from the restore CD

Table 8-1

No. Action
