The UR20-FBC-MOD-TCP eld-bus coupler is a Modbus TCP
participant developed according to IEC 61158. The coupler
is the head module for the u-remote system bus, to which up
to 64 active u-remote modules can be connected. The Mod-
bus TCP coupler has two Ethernet ports, and the integrated
switch supports a line network structure.
The coupler can be activated with a system-independent
web server application via the USB service interface or the
Ethernet. In addition, all information, such as diagnostics,
status values and parameters, can be exported and all con-
nected modules can be simulated or forced.
The station's main power supply is integrated in the coupler.
Power is supplied via two 4-pole connectors, separated into
the input and output current paths.
