Transmission protocols
For the connection of the UMG 503 to existing field bus
systems, two transmission protocols are at your disposal:
- PROFIBUS DP (Slave)
- Modbus RTU (Master and Slave)
The following protocols can be operate via RS485 inter-
face:
off no protocol, interface is not active.
1 Reserved
2 Modbus RTU (Slave)
3-
4 Service protocol
5 PROFIBUS DP (Slave), (Option)
6 Modbus RTU (Master)
*1)
The following protocols can be operate via RS232 inter-
face:
off no protocol, interface is not active.
1 Reserved
2 Modbus RTU (Slave)
3-
4 Service protocol
5 Modem
6 Modbus RTU (Master)
*1)
*1)
Protocol 6 can run only on one interface, RS232 or RS485, at the
same time.
Service protocol
The service protocol is used for calibration and testing
purpose in the manufacturing works only.
Modem
For the connection of the UMG 503 to a modem, the
protocol "modem" must be set at the UMG 503.
Operation of the UMG 503 via modem is only safe with
modems tested by the producer.
