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.

4. Method of operation
4.1. Operation principle
SU200 is equipped with powerful 16 bit microprocessors. This provides fully digital pre-processing of process data.
Process data are acquired at the field level via the digital and analogue inputs of SU200. The values are formatted into
telegrams and transmitted via a fieldbus link to the central control station.
Each recognised status change of the digital inputs is converted into a process message, marked with date and time with
1 ms. resolution, and written into a message buffer. These time-tagged process messages are together with analogue
values passed on to the central control station.
Control commands from the central control station are converted and provided in parallel form at the output circuitry of
SU200.
Each of the relay output channels is arranged with a feedback control circuit in order to monitor correct command
output.
4.2. Self-monitoring
All hardware and firmware functions of SU200 are continuously monitored by way of plausibility checks. If
irregularities are detected in hardware or firmware, a system message marked with date and time is written into the
message buffer.
The time-tagged system messages are immediately transmitted to the central control station as a common system
message.
Figure 20 shows the individual single system messages and the combination into the respective common system
message, which is then transmitted to the central control station. All single system messages can however be read from
the message buffer using SU200DIA application

4.3. Redundancy
SU200 is designed for fieldbus communications in single master or dual master configuration, whereas single master
configuration may be utilised via any of the two interfaces.
The redundant communications interface enables SU200 to be integrated in a station control system in hot standby
mode.
SU200 User manual

consent of Siemens AS. Offenders are liable to the payment of damages. All

A hot standby configuration at the higher station control level is achieved with an active and a passive central control
station (master), representing a two-channel configuration with a dynamic 1-out-of-2 redundancy. Both central control
stations run in a parallel mode, each with a full update of the process image at any time.
If a hardware or firmware error is detected in the active central control station, immediate and bumpless transfer to the
hot standby (passive central control station) is executed by means of an automatic switchover system and the hot
standby becomes active control unit.
The switchover between master and hot standby is executed without any loss of information and the process is kept
going.
SU200 is designed to accept and process orders received from the active central control station only. If SU200
recognises a switchover of the two central control stations via a specific bit pattern in the received telegrams, the actual
output commands are frozen for 3 seconds.
After 3 seconds, new output orders from the central control station are accepted by SU200 only if one single active
central control station is recognised, in all other cases the command output is reset (command ending).

4.4. Data transfer
4.4.1. Fieldbus
SU200 is designed for data interchange between station and field control level via a fieldbus.
For the open communications between the central control station (master) at the higher station control level and SU200
at the field control level, the PROFIBUS fieldbus is used.
PROFIBUS defines the technical and functional characteristics of a fieldbus and provides for extremely fast handling as
well as comprehensive interchange of process data.
PROFIBUS offers an extensive range of network components for electrical and optical transmission and combines
simple installation and service, good diagnostic facilities and an error-free transmission in an optimal manner.
4.4.2. Network configuration
With the use of star couplers, repeaters and/or optical link modules (OLM‘s) and optical link plugs (OLP‘s), the
PROFIBUS network can be configured individually in a in-line, ring or star topology and allows the linking of two-wire
(copper) and fibre optic transmission media.
4.4.3. Principle of operation
Data exchange on the PROFIBUS fieldbus runs in a programmed cycle using the principle of a master-slave system as
specified in European Norm EN 50 170.
Masters only may initiate requests for data, slaves may only respond to this requests.
4.4.4. Transmission media
SU200 is equipped with two ports for connection of an electrical transmission media and another two ports for
connection of an optical transmission media (redundant interface). Only one of the two communications interfaces
(electrical or optical) of SU200 can be in service at any time.

4.4.5. Electrical transmission media
• The electrical PROFIBUS fieldbus is arranged with 2-core (twisted pair) double-shielded cable.
• Transmission standard RS 485 is utilised.
• The RS 485 interface operates on voltage differences and is therefore less sensitive to interference than a voltage or
current interface.
• The maximum number of nodes of an electrical fieldbus is 32 per segment.
• By means of repeaters a two-wire network can be extended to 127 nodes.
• SU200 is suitable for transmission speed of up to 1.5 MBaud. In particular cases, transmission speed of up to
12 MBaud is possible.
4.4.6. Optical transmission media
The fibre optic network is set up with duplex fibre optic cables (glass or plastic) and is insensitive to electromagnetic
interference.
FO cables serve to transmit signals by means of electromagnetic waves in the region of optical frequencies. SU200
transmitter and receiver are suitable for transmission speed of up to 5 MBaud.
For communications between bus nodes, there is no discernible difference between the two-wire and fibre optic
technology.
4.5. Telegram structure
4.5.1. From SU200 to Master
For the data transmission from SU200 to the central control station (master), the telegram is structured with 32 bytes of
user data.
SU200 will automatically switch between transmission of various types of telegrams:

When a new process- or system-message is generated, SU200 will transmit this
message for 2 out of 3 times until it’s acknowledged, thus while waiting for
acknowledgement; analogue values are transmitted in every third telegram.

Two control bytes and the actual state of all digital inputs are incorporated in all telegram types and is
permanently updated and transmitted.
The message telegram consists of control bits incorporated into control bytes #1 and #2, the actual state of all
digital inputs and a maximum of three messages. The input status is permanently updated and transmitted.
Each message consists of its signal identification (double-word / two bytes) and the time of acquisition in a
six byte code, consisting of the days since 01.01.1984 and the milliseconds after the last full day from
00.00.00
h
onward.
The analogue value telegram consists of the control bits incorporated into control bytes #1 and #2, the actual
state of all digital inputs and the actual measured values of the 8 channels. The input status and the analogue
values are permanently updated and transmitted.
The kWh counter telegram consists of the control bits incorporated into control bytes #1 and #2, the actual
state of all digital inputs and the actual kWh counter inputs of the 12 kWh counter channels. The input status
and the kWh counter values are permanently updated and transmitted.
The general scan telegram is only transmitted after a request from the central control station and consists
likewise of control bits incorporated into control bytes #1 and #2 and the actual state of all digital inputs. In
contrast to the message telegram, the general scan telegram consists of eight messages with only one
common scan time information.

Control bytes #1 and #2 of the telegrams from the master to SU200 serve for communications control.
4.6.2.1. Control byte #1
Bit87654321
XXXX1/00/11/00/1
Togglebits enabling SU200 to monitor the communication.
These bits should be permanently toggled by the central control
stations between the bitpatterns "01" and "10".
SU200 will assume that the connection to the central control station
is interrupted if no toggling occurs within 4 seconds.
See chapter Figure 23 - Arrangement of control byte #2 in telegram
from master to SU200
Communications monitoring.
The combination "00" or "11" is illegal. Illegal telegrams are
ignored by SU200.
Request for active/passive central control station.
10 The central control station wants to be active.
01 The central control station wants to be passive.
The combination "00" or "11" is illegal. Illegal telegrams are
ignored by SU200.
See chapter Redundancy.
If both central control stations (in dual master mode) want to be
active, this is interpreted by SU200, as both units want to be passive.
Acknowledgement of a message block.
This bitpattern should be set-up by the master in order to
acknowledge the receipt of a message block.
When SU200 transmits a message block with messages, which
hasn't yet been acknowledged, a new message block number is
transmitted. The master signals the receipt of the message block by
returning the received message block number in these bits.
This bitpattern is ignored in telegrams from passive central control
stations.

4.6.3. Communications monitoring
Communications monitoring is done on both sides of the fieldbus link. In addition to the data transfer
monitoring carried out by the PROFIBUS master, each SU200 is permanently monitoring the data transfer
link via the toggle bits in control byte 1 received from the master.
The bit-patterns "00" or "11" are illegal. Illegal telegrams are ignored by SU200.
If a telegram with a new bitpattern in the togglebits isn’t received by SU200 every four second, a
communications error is recognised and the actual command outputs are reset.
As soon as a new valid telegram is received, communications is considered as healthy again.
4.7. Cyclic buffer
SU200 unit is equipped with a message buffer for storage of up to 500 process messages and 50 system
messages The buffer is designed in a write-over mode, i.e. in case of a buffer overflow, the ”oldest“ stored
message is overwritten.
Messages, which have been transmitted to the central control station, are kept stored and can still be read
using the SU200DIA application
Transmitted messages are marked as acknowledged as soon as the central control station returns the message
telegram number, see chapter From master to SU200.
4.8. Clock control
The date and time information for time tagging of messages is provided via the internal clock of SU200. The
internal clock is designed with an accuracy of 10
After start-up of SU200, the internal clock starts with 00:00:000
with the date 1984.01.01.
-5
(max. 36 ms/hour)
h
and time tagging of messages commences
As soon as the communications link with the active master is in service, the internal clock of SU200 is set
provisionally with the lead time information received via the first telegram from the central control station.
Subsequently, the time mark of messages, which have been written into the message puffer prior to the
reception of the first telegram, is corrected relatively to the time difference.
The time information sent by the central control station is given a few seconds ahead of the actual time and
serves as a lead-time for the setting of the internal clock via an external trigger signal.
For the time synchronisation of the internal clock, an optical and electrical trigger signal input is provided.
The unit is designed to receive a time synchronising impulse (at least 100µs) from an external master clock

6.1.4. Signal ID
Each of the digital inputs has a signal ID, which is unique in the entire control system and is pre-condition for
a proper processing and distribution of signals.
The range of the signal ID is 0 to 32767.
If the signal ID is set to 0, the signal status of the respective input channel is reported as normal, but no
message is generated by SU200. However, if a general scan telegram is transmitted to SU200, the signal
status of all channels is reported independent on whether the signal identification is 0 or any other number.
Each of the digital inputs of SU200 unit should have a unique ID (exception: ID number 0 may be specified
for several channels).
6.1.5. LED
A LED mode may be specified for each of the digital inputs.
If Follow mode is selected, the LED will continuously indicate the current alarm status or the physical
input signal status (depending on the setting of the Physical signal level on LED’s parameter).
If Storage mode is checked, the LED indication of the digital input is stored. This applies both for
indication of alarm-status or physical input signal. The LED will remain lit until the LED TEST button is
pressed.
If Physical signal level on LED’s is unchecked, SU200 will indicate alarms on the LED’s. Since both
positive and negative logic may be applied to digital inputs, a lit LED may not necessary indicate a high
signal on the input.
If Physical signal level on LED’s l is checked, SU200 will indicate physical signal levels on the LED’s. A
high signal on the input will cause the corresponding LED to light even if negative signal logic has been
applied.
The Physical signal level on LED’s parameter is common of all digital inputs, it can not be programmed
individually on a per-channel basis.

6.1.6. Logic
For each of the digital inputs, the user may specify the normal signal level.
If positive logic is checked, a high signal indicates an alarm condition.
If negative logic is checked, a low signal indicates an alarm condition.
6.1.7. Mode
A mode can be set for each of the digital inputs:
Normal mode.
The digital input is an impulse counter. No signal-alarm is generated from the digital input. The logic
level parameter does not apply. The LED will be continuously switched off. Read more about impulse
counters in chapter 6.3.4.
6.1.8. Timing
The user may define a Dead time and a Filter time for each of the digital inputs. A common time unit for
both time values can be selected in the Unit control.
Both time values serve as defined criteria’s for the generation of process messages, the digital input status
that is permanently transmitted to the control station is independent of this filtering.
The time values may be set in the range of 1 to 250 of the selected time unit. The time unit may be set to
1ms. , 10 ms., 1 sec. or 10 sec. Thus a time range from 1 ms. to 2550 seconds may be selected.

6.3.1. Local Control
Local control mode can be used to control the relays of SU200.
This option is especially important in the course of pre-commissioning of the system, e.g. the control station
is not yet installed or not yet ready to operate and the output circuitry of SU200 should be checked.
Figure 35 - Local Control in SU200DIA
The local control mode window enables the user to directly control all relays from a PC rather than from the
central control station (orders from the central control station are ignored).
When local control mode is started, the current command status of the relays are read and indicated.
The relays can be closed clicking the corresponding checkbox.
The Activate Local Control checkbox must be checked in order to control relays. When this button is
unchecked, all relays are controlled from the central control station.
Local control mode can not be started while the window for simulation of digital input signals is open.
While local control mode is active, SU200 generates and transmits messages to the central control station
unless the checkbox Message Transmission blocked is checked and the Apply button is clicked. In this case,
SU200 will still generate and buffer messages, but the actual transmission of the messages is suspended until
the local control mode is deactivated.
Using the Message Transmission blocked, the user may to do on-site testing without having unwanted
messages transmitted to the central control station. However, since the generated messages are buffered, they
will be transmitted as soon as the local control mode is stopped, unless a hardware reset is applied to SU200.
Applying hardware reset to SU200 will also stop the local control mode.
The local control mode has higher priority than the interlocking-functions (rules). An output channel
normally controlled by the interlocking function can be forced high or low using the local control mode. The
interlocking function will regain control of the output channel once the local control mode is deactivated.
While local control mode is active, the status of all digital inputs are periodically read and displayed.
The bottom status-bar of the main window will indicate that local control mode is active.
SU200DIA application is periodically reading the digital inputs of SU200, any disturbance is detected and
will cause SU200 to switch off local control mode after 30 seconds.
Local control mode is switched off by closing the window or unchecking the Activate Local control

checkbox. Local control mode will also be switched off when SU200DIA application is terminated.
When local control mode is switched off, SU200 unit keeps the current relay outputs unchanged until new
commands are received from the active central control station.
If no fieldbus is connected or faulty communications is detected, all command outputs are switched off as
soon as local control mode is exited.
Communications monitoring is not carried out while local control mode is active; thus the command outputs
are not switched off, even if the communications central control station is interrupted.
The Fetch button is used to read settings from SU200. The Apply button is used to write settings to SU200. If
Auto apply is checked, every single change is applied immediately.
6.3.2. Simulate Digital Inputs
All digital inputs can be manually set to a high or low signal level. The simulated signal level is handled by
SU200, as it was the physical signal level, consequently the simulated signal level will affect all functions
which uses digital inputs.
Typically the simulation of digital inputs will be used for testing the interlocking (rule) function.
Note that the function can not be started while the window for local control mode is open.
Figure 36 - Simulate digital inputs in SU200DIA
An input signal can be set or reset clicking on the corresponding checkbox.
The physical input status is displayed and simulated. Negative logic is ignored.
A maximum of 20 digital inputs can be set.
The bottom status-bar of the main window will indicate that simulation of digital inputs is active.
The simulation of digital inputs is stopped when the window is closed or when SU200DIA is terminated.
When the simulation is stopped, the inputs are immediately set according to the level of the physical input
signals.
SU200DIA will read and display the relay output status from SU200. This enables the user to see the effect
the digital inputs has on the programmed rules (the interlocking function).
SU200DIA application is periodically reading the relay status from SU200, any disturbance is detected by
SU200 and causes digital inputs to be automatically switched off after 30 seconds.

6.3.3. Fail-To-Safe configuration
If the PROFIBUS communication is interrupted or if no active PROFIBUS DP master are recognised, SU200
will enter a fail-to-safe state.
In this state, the control of each relay can be configured:
- Open relay
- Keep relay in its current position
Figure 37 - The fail-to-safe configuration in SU200DIA
The window displays one checkbox per relay. A checked box indicates that the relay will remain in position
(closed or open) if the PROFIBUS communication is interrupted. An unchecked box indicates that the relay
will be open if the PROFIBUS communication is interrupted.
If the Default button is pressed, all checkboxes is set with predefined check-marks for the default
configuration.
The Fetch button is used to read settings from SU200. The Apply button is used to write settings to SU200. If
Auto apply is checked, every single change is applied immediately.
6.3.4. Impulse counter values
Activating this function from the tools menu, will display the window shown in Figure 38. This window can
be used to view/edit impulse counter values. Any digital input channel can be the source of an impulse
counter. Configuration of digital input channels to be used for impulse counters is performed in the main
window of SU200DIA, see Figure 27.
SU200 maintains 12 counter-registers that can be used to count e.g. kWh impulse signals. Every register is
associated with a digital input channel.
For digital input channels configured as counters the following apply:
• If the input level is high for min. 20 ms, the corresponding counter register is incremented by 1. The
pause time between pulses is not monitored.
• No signal-alarms is generated for the channel.
• The applied dead/filter-time parameter for the channel is not used.
• The logic level (positive or negative) parameter does not apply.
• The status of the input channel (high or low) is available as “normal”.
• The LED will be continuously switched off.
The counter registers will overflow from 0xFFFF to 0. The values are stored in volatile memory and thus
cleared at power-up.

6.3.5. Analogue input scaling
Each of the analogue input raw values from the AD converter (12-bits+sign) are scaled by a
fraction equal to
4095
From the window shown in Figure 39, the denominator of the scaling fraction can be set individually for all
analogue input channels. The final result is truncated to a range from –4096 to 4095.
The default value is 3236. No scaling will be applied if the value 0 is selected

Parameter Description
Master switchover timeout SU200 can be controlled from one out of two PROFIBUS DP masters through
the redundant PROFIBUS interface.
During the switchover of active PROFIBUS DP master, there may be a short
time-period in which none or both DP masters wants to control SU200. The
maximum time-period can be set with the
Master switchover timeout parameter.
If this time is exceeded, SU200 will enter a fail-to-safe state. Depending on the
set fail-to-safe configuration, relays may be opened in this state.
Togglebit change timeout In the PROFIBUS telegrams sent to SU200 from the active PROFIBUS DP
master, two bits are used to indicate presence of new data. Read more about this
in chapter 4.6.1.1.
If this two bits remains frozen for the time set by the
Togglebit change timeout
parameter, SU200 will assume that connection is lost with the active
PROFIBUS master and enter a fail-to-safe state.
Analogue input filter factor Filter factor which is used to stabilise current readings.
All values are filtered according to the formula

Menu Function
Load rules Load rules defined in a text-file into SU200.
The use is prompted for a file with default extension
TXT.
The file is syntax-checked and compiled. Any semantic errors are reported both in a window and in a
generated report-file.
If the rules are correct, the compiled program is downloaded to SU200.
Reload rule
file ….
Reloads the last loaded rule-file (SU200DIA will save the name of the last loaded rule file and use that
name at the next start).
Clear rules Clear all rules in SU200. (any relays controlled by the rules are opened)
Verify rules Basically the same function as Load rules, except that the rules in a text-file are compared with the rules
currently programmed into SU200.
Rule status Indicates if SU200 has a rule program or not.
Table 10 - Rules menu in SU200DIA
All rules are compiled to a single program in machine code by SU200DIA. This allows the fastest possible
evaluation of the rules. The size of the rule-program is limited to 1024 bytes.
The interpretation of the rules is carried out at by SU200 at power-up and cyclic every 4 ms. during normal
operation.
The relays controlled by the rules can not be controlled from the fieldbus master.
The rules defines logic which may be performed on:
Signal levels of all digital inputs
•
•
Internal state variables in SU200
For digital inputs specified in the rules, the following apply:
Any digital input channel (1-40) may be specified
•
•
Signal transitions are recognised without any delay at all.
•
The applied dead and filter-time parameter for the channel is not used when the rule is evaluated.
•
The logic level (positive or negative) parameter for the channel is not used when the rule is evaluated.
The following state variables may be used in the rule logic:
State variables Description
1 SU200 healthy
Set to “1” if all the following conditions are true:
Memory OK (RAM, EEPROM)
•
•
The internal hardware watchdog has generated no reset.
Both power supplies are functioning.
•
The time synchronisation signal is correctly received within 30-minute time windows.
•
Note: Writing to this state variable in the rule program, will only change the variable for a max. of 4
ms., as the state variable is updated by a 4 ms. firmware cycle.

2 (In firmware version older than V3.00, this state variable is fixed set to 0).
Set to “1” if the message buffer overflows. This happens when 500 unsent messages are stored in the
message buffer and a new signal message is raised (not system message).
This state variable can be reset clicking the LED-TEST button.
However, if a message condition is present, the state variable will be immediately set since the
message buffer isn’t cleared when the LED-TEST button is pressed. Following a LED-TEST button
press, any set alarms are re-reported.

SU200 will verify the rule program at power-up and after download by means of a 16-bit checksum. A
system alarm is generated in case of checksum error.
The rules may be tested by means of simulating the inputs.
The level of the outputs controlled by the rules can only be overridden -setting by the local control mode.
No indication is sent to the central control station when an output is set, reset or blocked due to a rule.
The following types of function blocks can be programmed:

6.3.7.8. Rule file macros
In order to avoid directly addressed input/output signals in the rule functions, i.e. SET O1=I1&I2 a macro
function can be used.
Macros are defined using the syntax:
DEFINE <macro> <text>
<macro>
A token which may consist of one or more alphanumeric (letters and digits) characters terminated by a
space (e.g. the “_” character can not be used in macro-names).
Any occurrence of the word given by <macro> in the rule file will be replaced by <text>. Macro
definitions are however not recursive. Any text following after a DEFINE statement will not be
evaluated using the macro substitution.
<text>

6.3.11. Downloading new firmware
Warning
The download of a new firmware is not a 100% secure process. Any unexpected failure during the
download, e.g. a power-down or PC failure may cause the download to stop. In this case, the main
flash memory devices in SU200 must be replaced as described in Appendix D.
Special procedures may be required to perform a firmware upgrade without changing the SU200 operating
parameters. This procedures depends on the firmware version. A safe procedure would be to use SU200DIA
to upload/save parameters prior to the download, then re-apply these parameters after the download has been
completed.

8.1. General
Prior to the commissioning, check that the order number shown on the nameplate matches with the intended
application.
safety instructions can result in severe personal injury or property damage.
Only qualified personnel should work on this equipment. These personnel should be thoroughly
conversant with the relevant safety measures and the warnings contained in this manual.
Note in particular that:
The equipment must be properly earthen before connecting any cables.
•
•
Hazardous voltages may still be present after the auxiliary power supply has been disconnected
or switched off (electric charge).
Under certain circumstances it might be useful to carry out the functional checks of SU200 in the course of
the commissioning of the secondary circuitry of the process, i.e. during checking the interaction between
SU200 and the connected process (e.g. switchgear).
An industrial standard PC is part of commissioning tools and allows, just as an operator panel, all necessary
settings, read-out of data and initiation of command output with the added comfort of visualisation and
menu-guided procedure.
SU200 is ready to operate when the required operational parameters have been entered. Parameterisation is
done by subsequent entering of settings or by downloading all parameters from a parameter file.
8.2. Checking the auxiliary power supply
Prior to the function tests of SU200, the auxiliary power supply circuits are to be tested for correct polarity
and fusing.
After closing the m.c.b. of power supply circuit 1, the voltage magnitude is measured at the input terminals.
The unit starts up and after completion of the run-up period, indicated via a short-time flashing of the upper
40 LED‘s, it must be checked that LED #1 (OPERATION) and LED #2 (POWER SUPPLY) of SU200 light
up accordingly.
Subsequently, the aforesaid steps must be repeated with power supply #2 only, see chapter LED display.
8.3. Checking the fieldbus link
The communications interface with the central control station(s) is to be checked for proper connection. For
optical bus links, the allocation of transmitter and receiver channels is to be checked.
Electrical bus links must be checked for correct polarity of the inner conductors and for proper treatment of
the cable screen.
After putting the central control station(s) into service, it must be checked that the respective LED on SU200
(INTERFACE 1 and INTERFACE 2) light up and, thus, indicate healthy data transfer.

8.4. Checking the clock control and time synchronisation
8.4.1. Checking the clock control
Prior to putting the fieldbus link(s) into service, the internal clock control of SU200 is initially checked by
way of fetching the message log of SU200 using SU200DIA application.
After SU200 start-up, the system message S101 is generated and logged as shown below.
Figure 57 - System message 101, SU200 time not yet synchronised
In order to check the internal clock control of SU200, the communications interface with the central control
station(s) is then put into service.
Subsequently it is to be checked, that the internal clock is set with the advance time (lead-time) received via
the first telegram from the central control station and the time mark of S-101 is corrected accordingly.
Figure 58 - System message 101, SU200 time has been synchronised
8.4.2. Checking the time synchronisation
A trigger signal is to be simulated on both interfaces by way of applying an appropriate voltage signal to the
electrical synchronisation input and connecting the optical signal input. In each case correct function is
indicated via LED #39.
In order to check correct clock control and time tagging, a process message should be generated by way of
simulating a status change on a digital input at a definite time. Subsequently, the message log of SU200
should be read and checked for correct time tagging.
8.5. Checking the digital input
After completion of the cabling, the digital input is tested by way of subsequent initiation or simulation of the
input signals at a suitable point and by checking the correct response of SU200 with regard to:
Correct acquisition and channel association
•
Correct LED display
•
•
Correct status image processing
Correct generation of process messages

8.6. Checking the command output
After completion of the cabling, the command output is checked by way of giving respective commands
either from the central control station or by means of SU200DIA application.
In doing so, the proper function is tested by checking the correct response of the associated connected
devices (high-voltage switching devices, control and protection units). At the same time, the corresponding
LED display on SU200 must be checked.
8.7. Checking the analogue inputs
After completion of the cabling, the analogue inputs are tested by simulating the respective measured
variables at a suitable point (either at the input terminal of SU200 or preferably at the external measuring
transducer or transmitter). Check the correct response and data pre-processing of SU200 with regard to:
Correct acquisition and channel association
•
•
Correct conversion and transmission
•
Correct conversion into percentage values for diagnostics
The simulation of analogue inputs can be done using an appropriate secondary test set.

Appendix C PROFIBUS Test Tool
The PROFIBUS test tool allows a PC to be connected to one of the two PROFIBUS communication channels
of SU200. The tool can be used for testing and demonstration of important features of SU200.
The PC must have a PROFIBUS master card installed. Currently two types of cards are supported:
Siemens CP5613
•
•
Siemens CP5412
The CP5613 card is operated with drivers for Windows NT, the CP5412 card has drivers for Win9X and
Windows NT. Before the tool can be properly operated, a manual set-up of the PROFIBUS card is required,
see appendix C.1.
Note that the installation of the PROFIBUS drivers and the COM PROFIBUS application requires an
authentication disk (the drivers are copy-protected) as well as a SIMATIC NET CD.
Launching the PROFIBUS test tool will display the window as shown in Figure 61.

Control Description
Adr Select the PROFIBUS address of the connected SU200
Type Set type of PROFIBUS card in the PC. The card must be installed. A PROFIBUS network
set-up should be created using COM PROFIBUS and loaded into the PROFIBUS card. See
appendix C.1
Id Access point for the PROFIBUS card. Unless there are more than one PROFIBUS card in
the PC, the default value can be used.
For CP5412 cards, this control states the board number (1.4).
•
•
For CP5613 cards, the controls states the access point, e.g. CP5613_5614_1, where the
last digit is the board number.
Write-Time The PROFIBUS test tool does cyclic send telegrams to SU200 by the rate given by Write-
Time (in ms.).
The SU200 is operating as a DP slave and responds when new telegrams are received.
If a high time-value is set, the data exchange is operated at a slow rate, allowing the user to
visually inspect received and transmitted telegrams.
The minimum value depends on the type of PROFIBUS card installed. For CP5613 cards,
the min. value is 4 ms., while the min. value for CP5412 card is 10 ms.
The actual cycle-time (measured time between every received telegram from SU200) is
indicated in the status-bar.
On New Check this checkbox to activate the fastest possible data exchange rate with SU200.
The PROFIBUS test tool will transmit new telegrams to SU200 with the minimum Write
Time. To increase the speed, a new telegram is sent immediately when the PC receives a
new telegram from SU200 without respect to the set WriteTime.
Master mode Select if the PROFIBUS test tool is active or passive master.
Only an active master is allowed to:

However, if a second PROFIBUS test tool is running and also connected to SU200,
both PROFIBUS masters will be set to passive master state in the case where they are
both requesting to be the active master (only one interface can be the active master).
You are slave indicates that the PROFIBUS test tool is operating as a passive master.
•
This checkbox is checked if passive master mode has been selected.
Device OK indicates that both power supplies and internal memory of SU200 are ok.
