GSD file
The GSD file is a device specific file, in which the transmission parameters and the kind of measured data between
the Profibus master and slave are determined. The Profibus slave in this case is the UMG507P/EP and the Profibus
master, for example, a PLC.
The GSD file of the UMG507P/EP can be found on the CD-ROM PSWbasic/professional or in the Downlaod area on
our homepage (www.janitza.de).
The GSD file of the UMG507P/EP supports the following modules:
Device address
If several devices are connected via the Profibus interface, the master (PC or PLC) can tell one instrument from the
other by their device address only. Within one network, each device UMG 507 must have its own device address.
Profibus supports device addresses in the range of 0...126. The device addresses are set at the instrument as follows:
Confirm key 1 two times Select flashes. With key „2“ cancel
selection. Confirm key „3“ three times
to call up display „device address“.
Using key „1“ you select the first digit
of the device address, which can be
changed with key „3“. The selected
digit flashes. When the desired
device address is set, confirm key
„1“ until no digit flashes anymore. By
long pressing of key „1“ you leave
configuration menu.

Creating new profiles
The UMG507P/EP has four defined Profibus profiles. While using the delivered configuration program PSWbasic/
professional, new profiles can be created in the program part UMG507 „Configuration of profiles for Profibus“. The
measured values, which must be transmitted are selected and marked within the instrument. Install the software
PSWbasic/professional on your PC. After starting the software go to menu „Configuration Software“, „Define measuring
devices“. Connect the delivered RS232 interface cable to the RS 232 interface of the UMG507 and define the device
within the software.
Select the device type UMG
507 in the Drop Down field.
Press function „add
measuring device“.
Check the Com-Port settings next. Press Com-Port within
the measuring device list. In the manufacturer’s settings,
the configuration is as follows: Device address = 1, Baud
rate = 38400, Protocol = 0. If the device address was not
changed, the settings can be used unchanged.
Test transmission by clicking function „Device info“.
Only for the devices UMG507P and UMG507EP
the option Profibus is available. The other device
types do not support Profibus, and it is not possible
to release Profibus after sales.

8
Open the menu „Configure Profiles
for Profibus“ in menu UMG507. The
first four profiles are not changeable.
20 user defined profiles can be created. Select the profile
„user defined 1“ from the list.
On the right side the possible measured values can
be found. After the selection of a measured value,
please select the data format, floating point format or
integer format.
... At disposal:
- Measured value
- Mean value
- Minimum value
- Maximum value

9
For each user defined profile up to 64
entries are possible. The parameter
number provides the internal register
address (see address list UMG507).
Transmit the profile to the UMG507P/
EP.
Save the profile in a file and transmit it
to the device (Send configuration to
UMG507).

10
For integer values, the scale
must be set additionally. Go to
menu „Configure UMG507“ and
enter panel „Method of
measurement“. After changing
the scaling, it must be
transmitted to the UMG507P/
EP as well.
The solution or scaling must be chosen in a way, that the range of the integer format (e.g. - 32768 to 32767) is not
exceeded. Furthermore it must be selected in a way the solution is as high as possible. Apart from the energy values
(in kWh, kvarh) the measured values are transmitted in their basic units (V,W,VA etc.).
The data formats in integer format are as follows:
Apart from energy, all measured values in format WORD (2Byte) : -32768 to + 32767
Energy values in format LONG (4Byte): -2147483648 to + 2147483647
Some examples:
Example real power:
With a current transformer ratio of 200/5A and a voltage transformer ration of 400V/400V the maximum sum real
power can be 240kW. The transmitted value at a scale factor of „1“ would be 240.000. As the integer range is
exceeded by far, the scale should be set to „/10“. Using this scale, the UMG507P/EP would transmit 24.000 as a
maximum, which is within the integer range and provides the best solution. The measured value is calculated:
Measured value =Transmitted value * scale factor
Example voltage:
Value at display = 230,3V; Scale = *1 ;
Transmitted value in PLC = 230
Value at display = 230,3V; Scale = *10 ;
Transmitted value in PLC = 2303
Example Cos-phi:
Value at display = 0,995; Scale= *1 ;
Transmitted value in PLC = 0
Value at display = 0,90; Scale = *1000 ;
Transmitted value in PLC = 995
Example Frequency:
Value at display = 50.03; Scale = *1 ;
Transmitted value in PLC = 50
Value at display = 50.03; Scale = *100 ;
Transmitted value in PLC = 5003

11
The configuration at the PLC (e.g. S7) is done as follows:
Install GSD file:
In the hardware configuration in menu point „Extras Install new GSD“ the GSD file is imported. After installing the GSD
file the catalogue must be actualized.
Insert a measuring device into the DP master system:
Go to the folder Profibus DP in the hardware catalogue. Under field devices „Others“ the UMG 507P/EP, installed by
the GSD file can be found. Mark a module, for example „STD: 24 Word In, 2 Byte Out“ in the catalogue and drag it
with a pressed mousekey into the DP master system. The software asks for the address of the instrument. Set the
address, which was programmed at UMG507P/EP before. Please note, that the addresses may not be given twice.
Hint regarding the module: It is not vital to read out the complete profile. If only the first measured values of a
profile with e.g. 64 Word are required, a smaller module with e.g. 16 Word can be selected.
Make table of variables (VAT)
For testing communication, please make a table of variables. Move to the respective menu in the project overview.
After calling up the variable table, the operands must be assigned. The assignment results from the address range,
which was automatically given in the hardware configuration.

etc.
Example real energy:
The energy is always transmitted with the unit kWh. Using the format LONG at scale *1, the transmission value is
limited to 2147 GWh. But the display range of UMG507 is up to 9999GWh. The scale factor depends on the power of
the panel. For small to bigger panels, a scale factor of 1 can be selected, as 2147 GWh are usually big enough. For
very large panels, a scale factor of 10 should be selected. This results in a solution of 10kW. The maximum measured
value would be 21474 GWh
There is the alternative to reset energy over a Profibus flag whlie reaching the limit of 2147 GWh.

Profibus flag:
Via Profibus flags internal target action can be released, which means, the PLC for instance controls directly via
internal functions of the UMG507P/EP.
The programming is done in PSWbasic/professional in window „Output channels“.
The following actions are possible:
- Set a digital output.
- Send Email (only possible at UMG507EP).
- Start / stop second timer.
- Start / stop integrator (integrates any measured value over time).
- Tariff changeover of energy meter (real / reactive energy).
- Maximum demand control, target value changeover.
- Saving a parameter in the parameter memory.
- Synchronize internal clock on next full hour.
- Reset measuring period (Maximum demand controller).
- Reset real and reactive energy.
- Reset the minimum and maximum values (e.g.current, voltage etc.)
Furthermore, the Profibus flags can be used in the logical combinations.
Trigger status:
The status feedback of the trigger events (short interruptions) lay in the input range of the PLC on Byte 2 with a fixed
follow-up time of 10 sec. which means, after a short interruption, for example of voltage in phase 1, the status Bit of
the event is left on high level for the duration of the event, but at least 10 seconds. The reaction time is <200ms. The
programming of the trigger event is done with PSWbasic/professional in window „Trigger events“. The overcurrent
events are „OR“ combined on the same Bit.
Analogue outputs:
The internal analogue outputs of the UMG507P/EP can be controlled via Profibus as well. The range of 0 to 65535
can be assigned to 0 (4) to 20mA via PSWbasic/professional. The internal parameters 9000 or 9002 are used.

13
Examples:
Example 1: Use of the Profibus flags
The internal clock shall be synchronized via Profibus flag 1 for the next full hour, and additionally, the Profibus flag 2
deletes the energy counter for real power. At first, install a UMG 507 P/EP in software PSWbasic/professional as
written in chapter „Create new profiles“. Change to menu „Configure UMG507“ into window „output channels“.
Assign output channel 1 to the
target function „set clock“ and
output channel 2 to action „reset
real power“.

Example 3: Analogue output
The control of the analogue output is carried out via the 3. and 4. or 4. and 5 Byte in the output range. Die Daten
werden fest auf die Parameter 9000 bzw. 9002 geschrieben.
Configure the analogue outputof the
UMG507P/EP to the parameters 9000 or
9002 and set the scale for the scale
starting value and scale end value.
In the above mentioned example, the scale starting value for the analogue output was set to 0 and the scale end value
was set to 300. A decimal e.g. of 150 on the 3. and 4. Byte in the output range results in an output of 10mA.
