CONTROL SYSTEM FOR CONVERTER PSR-SYSTEM

Fieldbus Coupler 32 I/O

UP C090 AE

FEATURES The "Fieldbus Coupler 32 I/O" belongs to the PSR2 family of devices and is in turn, a

member of the remote peripherals with a connection to the Fieldbus. 32 digital inputs for connection to a passive opto-interface. 32 digital, short-circuit proof outputs suitable for direct connection of passive relay interface

with 16 channels. The device is intended for both wall-mounting as well as insertion in standard cubicles (to

snap on a top-hat rail). The connection on the bus side is carried out using a BNC-coaxial connector whereas on the

customer side is by means of a flat cable; with 16 channels per cable.

SHORT DESCRIPTION Purpose

The "Fieldbus Coupler 32 I/O" is a node on the ARCnet-Fieldbus with 32 digital inputs and outputs. It transmits in serial, the 32 input/output signals to and from the processing controller via Fieldbus (coaxial cable). In this way, a remote acquisition and transmission of control signals is achieved with a minimum amount of wiring effort.

Function

The process input signals on the customer side are cyclically read by a micro-controller (C), pre-processed and stored in the RAM. On the other side, the control commands of the processing controllers are received, saved and output in parallel via Fieldbus.

The data transfer on the bus is only performed by the ARCnet-controller and in asynchronous to C. The bus control as well as error handling are integrated in the system protocol. A driver is installed on the bus side which is able to drive a medium size remote system in a bus or star topology.

2.2 Power Supply

An external supply voltage of +24 Volt DC is required. The non-electrically-isolated voltages of +5 Volt and -5 Volt are created internally. As long as the power supply is not in order, a watchdog of 5 supply voltage sets the "Reset" signal high. A green LED indicating "power supply ok" is turned off in case of a faulty power supply. In order a fault in the device not to block the 24 Volt input voltage, a replaceable fast fuse of 2,5A is inserted at the input.

2.3 ARCnet- and Micro-controller

The combination of the micro-controller 80C31 and ARCnet-controller COM 20020 controls the whole function of the network nodes. The micro-controller accesses the software saved in EPROM via its ports 0 and 2. The software on one hand, controls the Interface to hardware, on the other hand, the data transfer to the bus-controller. This in turn controls the complete traffic on the Fieldbus. For the bus-protocol, it should be referred to the software specification which is not discussed in this paper.

Memory

The 8-bit micro-controller 80C31 provides a maximum memory range of 64 kBytes of program code as well as 64 kBytes RAM. The RAM memory is in addition to the controller memory, used for the I/O interface and node addresses. The corresponding memory partitioning is shown in the following diagram:

HIEE 420289 E

- 7 - UP C090 AE

Node Addresses

Each node in the network must have a unique address. The address is selected by means of a DIP-switch S201 in range 1..63 and can be chosen on-will as long as it is unique within the network. It should be noted that the nodes are processed in the order of their addresses.

2.4 Line Driver

The line driver Hybrid HYC 9088 converts the digital signals of the serial output of the ARCnet-controller into electrically-isolated and DC-free "dipulses" which are then transferred to the bus. Besides, it also receives dipulse signals sent by other nodes and converts them into mC-compatible digital signals. It is also able to drive a coaxial cable (RG 62). The link from one device to another is carried out using a BNC-T through which the device can be mechanically separated from the bus without disturbing the rest of it. On both ends, the bus cable must be terminated by a 93 Ohm surge impedance. The bus driver is electrically compatible with the standard ARCnet systems. The bus partitioning which avoids the data collision is implemented in the software protocol.

2.5 Interface to Hardware

Inputs

The status of the 32 input channels are read by the two connectors X1 and X2, converted into 5 Volt and transferred onto the internal bus via four 8-bit transparent latches. These are always read 8-bit in parallel. During reading, the input latches are blocked in order to keep the data consistency within one byte. On these connectors there are at the same time, +24 Volt and 0 Volt outputs which are used to directly read either passive opto-interface or galvanically-isolated contacts.

Outputs

As outputs, there are also four 8-bit latches which are individually written by the data bus. After conversion to 24 Volt, they are transferred to 16 channels of the two output connectors X3 and X4. The output connection is suitable for direct control of a passive relay interface. Each output is individually monitored against short-circuit. If a fault occurs, the corresponding channel is disabled and this is read by the controller and reported on the bus as a fault alarm. After the fault clearance, the channel can be enabled again using the release key S101.

2.6 Monitoring

The following hardware supervisory circuits are included in the device. The power supply supervision or watchdog alarm is indicated by clearing the green LED.

Power Supply Monitoring

This supervises the failure of +5 Volt and -5 Volt power supply as well as undervoltage and at the same time, by power-up creates a power-up signal through which the bus driver and controller are set to stillstand (hold).

HIEE 420289 E

- 8 - UP C090 AE

Watchdog

The device contains a watchdog which supervises the correct program sequence and in case of a malfunction restarts the controller via an interrupt routine as a first step. If this doesn't clear the fault, it creates a "Reset" signal to block the bus driver so that the network detects the fault. This error is saved and can be only reset either by the power supply or the release key (S101).

Besides, there is a time-out (ARCnet-condition) which forces a bus initialization, if the node doesn't receive the token for longer than 840ms. The bus initialization takes ca. 2s. Furthermore, if a device is defected, the network detects it automatically, but the rest of the bus traffic is not disturbed. The same applies when the device is put back into operation in which it automatically returns into the logical ring.

Short-circuit Monitoring

This is described in chapter 2.5 "Interface to Hardware".

3.4 Input/output Memory Assignment

The 32 inputs (connectors X1 and X2) as well as the 32 outputs (connectors X3 and X4) each occupies 4 bytes of memory. The address assignment of the required data is carried out in FUPLA configuration as shown below:

Inputs (signals from the process to the controller)

The Size_IN defines the number of the bytes to be transferred. The offset can be assigned in FUPLA, otherwise, it is inactive meaning that the transfer always begins from byte 0.

4. COMMISSIONING AND FUNCTION CONTROL

4.1 Commissioning Hints

- select the node address; this should correspond with the configuration in FUPLA

- insert the interface

- connect the bus cable; if the device is the last one on the bus, a termination resistor must be connected to the free end of the BNC-T.

- switch on the 24 Volt power supply

4.2 Function Control

- after switching on the power supply the green LED must come on after a short delay (ca. 6s).

- if the LED is not on, it could be that it is not yet initialized by the master and/or has not received valid data. To find out whether the device is serviced correctly by the master, the software must be checked.

- if the LED is not on, although the master runs correctly, the fuse must be checked. If this is ok then the device is defective and must be exchanged.
