WAGO I/O SYSTEM
A simple expansion of the inputs and outputs of the
UMG 503 is possible with the WAGO I/O SYSTEM. The
UMG 503 is connected to the bus coupling via an interface
cable. The
Modbus RTU
protocol is used for
transmission of data. Function clamps such as analogue
outputs, and digital inputs and outputs can be connected
to the bus coupling.
Function clamps
Function clamps, which can be used with the WAGO
Modbus coupling:
Digital inputs
750-400
2-chanel digital input 24V; 3,0ms
750-405
2-chanel digital input 230V AC

4-chanel digital input 24V AC/DC
Digital outputs
750-501
2 outputs, 24V, 0,5A
750-502
2 outputs, 24V, 2A
750-504
4 outputs,
750-516
4 outputs, 24V
750-519

2 outputs, 230V, Solid State
750-512
2 NO, Relay, potential bound.
750-513
2 NO, Relay, potential free
750-514
2 Change over switch, Relay, po-
tential free
750-517
2 Change over switch, Relay,
potential free
Analogue outputs
750-550
2-chanel analogue output 0-10V
750-552
2-chanel analogue output 0-20mA
750-554
2-chanel analogue output 4-20mA
750-556
2-chanel analogue -10V
As the Siemens data format is not supported by the UMG
503, the function clamps
750-580
0-10V and
750-584
4-20mA
cannot be used.

Installation instructions
The connection of the UMG 503 to the bus coupling can
be carried out via RS232 or RS485 interface. The WAGO
Bus coupling has always the address 1.
For operation with the WAGO bus coupling, protocol
number "06" must be set at the UMG 503 (
Modbus RTU
Master). Please note, that protocol "06" cannot be
operated on both interfaces of the UMG 503 at the same
time.
All existing analogue function modules must be pro-
grammed at the UMG 503. Only the last clamp of the
analogue module does not have to be programmed.
The analogue clamps must be plugged to the bus coupling
at first, and the digital clamps afterwards.
