The UMG507 supports the protocols Modbus RTU, Modbus TCP/IP, Modbus over TCP/IP (Modbus Gateway) or

Profibus DP V0, depending in the version. This functional description is an addition to the manual and describes the

configuration of the corresponding function step by step.

More functional descriptions can be found on the CD-ROM PSWbasic/professional. At present, the following functional

descriptions are available:

- UMG507 used as remote data display for external Modbus slaves

- OPC Server Port 502

- OPC Server Port 8000 (Modbus Gateway Function)

- The webserver of UMG507

Profibus

.The certified Profibus instrument UMG507P/EP supports Profibus DP V0 up to 1,5Mbaud.

The Profibus connection of the UMG507 is carried out as 9 pole Sub Dplug ausgeführt. For connection, we recommend

a 9 pole Profibus plug (Type: SUBCON-PLUS-ProfiB/AX/SC Manufacturer: Phoenix part no.: 27 44 38 0 or similar).

Profibus Profile

The UMG507 supports 24 Profibus profiles at the moment, where 20 are user defined configurable via PSWbasic/

professional. The assembly of the profiles is as follows:

UMG507P/EP Profibus plug SUBCON

390Ohm 220Ohm 390Ohm

VP (5)

GND (6)

Connection of the bus wires:

Connect the incoming bus wire always to the inputs 1A/1B (even at the beginning on a bus system!) The further

leading bus wire is always connected to the inputs 2A/2B. The terminal resistors will be activated by the switch at the

beginning and end of the bus system. At the same time the connection inputs (2A/2B) for the further leading bus wire

is disconnected.

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.

Display device address

Protocol setting

The RS485 interface of the UMG507P/EP is suitable for transmission of data over a distance up to 1200m. Up to 31

UMG507P/EP and a master (PC/PLC) can be connected. The RS485 interface of UMG507P/EP supports several

protocols, which can be selected directly at the device.

master .

cancel selection. Confirm key „4“

three times to call up display

„RS485“.

With key „1“ select the third line, and

change to protocol 2 by key „3“. The

desired protocol is set, confirm key

„1“ until no digit flashes anymore. By

long pressing of key „1“ you leave

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.

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

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).

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
