5.4 Modbus TCP eldbus coupler UR20-FBC-MOD-TCP
The UR20-FBC-MOD-TCP eldbus 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
Modbus TCP coupler has two Ethernet ports, the integrated
switch supports a line network structure.
The coupler can be accessed with a system-independent
web server application via the USB service interface or the
Ethernet. Thus, all information, such as diagnostics, status
values and parameters, can be read and all connected mod-
ules 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.
