1. Introduction
1.1. Application
The task of SU200 is to serve as a decentralised field control device in a microprocessor based station control and
monitoring system.
SU200 is developed for data collection, data pre-processing, data transfer and command output at the field control level
in medium-voltage and high-voltage substations, power stations and industrial plants.
SU200 is designed to be located in the immediate vicinity of the process with hard-wired parallel interfacing to the
various control devices Thus, a distributed intelligence ensures that process data is collected, logged and pre-processed
where it is generated.
Communications with the central control station is made via a PROFIBUS fieldbus, which offers interface for both
high-speed handling as well as for comprehensive interchange of process data.
The following functions are implemented:
• Acquisition and filtering of binary signals, e.g. from switchgear control and protection units
• Acquisition of analogue values
• Transmission of process data to the central control station
• Reception, conversion and output of relay commands from the central control station
• Time tagging and recording of messages
• Guaranteed data delivery of messages
• Self-monitoring / plausibility checking
• Monitoring of communications links
SU200 is designed to serve as part of a station control and monitoring system.
The functionality of SU200, together with an appropriate fieldbus link and the managing and co-ordinating functionality
of a central control station enables the execution of a large number of tasks.
Figure 1 shows how SU200 is incorporated in a structured station control and monitoring system.

3.2.2. CPU and communications module
The central processor unit (CPU) is responsible for pre-processing of acquired process data and organising of the data
exchange with the central control station.
The microprocessor carries out a full restart on power-up and reset.
For communications with the central control station, a redundant interface for both electrical and optical data
transmission media is provided.
For the connection of a redundant fibre optic fieldbus link, four bus terminals with bayonet coupling (ST standard ports)
are provided, consisting of two receiver and two transmitter ports designed to operate with 62.5/125 µm fibre optic
cables.
The receiver incorporates an integrated photo IC containing a photo-detector and dc amplifier driving an open-collector
output transistor.
The transmitter contains an 820 nm emitter capable of efficiently launching optical power into four different optical
fibre sizes.
The receivers are easily identified by their dark grey colour; transmitters are made in light grey colour.
In addition, 2 SUB-D jacks are provided on the CPU for the connection of a redundant electrical fieldbus link.
For the open communications, the protocol PROFIBUS-DP as defined by EN 50 170, part 3 is selected.
The fieldbus interface is arranged with subsystems containing a standard PROFIBUS-DP controller and a processor,
which communicates with the main CPU via dualport RAM.

3.2.4.1. Relay output monitoring
All relay output channels are monitored for correct command output.
By way of feedback circuits, the output of an individual channel is only released after a plausibility check has been
executed and the output circuitry is considered as healthy.
In case of malfunction, the respective output group (two channels) is blocked and a corresponding system message is
sent to the central control station.
3.2.4.2. Relay output circuitry
Each relay output channel is provided with two NO (normal open) contacts.
The output channels are organised by groups of two channels. Two output channels are connected to common paths and
enable, on one hand, double-pole switching and, on the other hand, switching in both directions (e.g. closing and
opening of an external control/switching device).
Figure 10 shows the general output arrangement and a typical connection of a high voltage switching device.
