Status messages of the u-remote station
In addition to the process input data a coupler status word as
well as module status bytes are transfered to the SPS. Thus
diagnostics and status messages can be read directly.
The coupler status word describes the status of the u-remote
station including the following information:
Coupler status bits UR20-FBC-EC
Bit Name Bedeutung
0 Summarized module diagnosis Module diagnostic is present. A diagnosis is available for at least one module with diagnostics functionality.
1 Errorbit 1 Reserve bit 1, currently not used
2 Errorbit 2 Reserve bit 2, currently not used
3 Systembus error Error on the system bus. Communication with the connected modules is disrupted.
4 Errorbit 4 Reserve bit 4, currently not used
5 Errorbit 5 Reserve bit 5, currently not used
6 I/O-Conguration error Deviation in the conguration. The module list has changed. The list of congured modules (Congured Module Ident List
0xF030) differs from the module list detected by the coupler (Detected Module Ident List 0xF050).
7 Master conguration error Master conguration error. The list of congured modules (Congured Module Ident List 0xF030) differs signicantly from
the module list detected by the coupler (Detected Module Ident List 0xF050). No process data can be exchanged with the
modules. The station switches into PRE OPERATIONAL state.
8 Errorbit 8 Reserve bit 8, currently not used
9 Errorbit 9 Reserve bit 9, currently not used
10 Force mode active Web server force mode is active. Force mode was activated through the web server. Process data cannot be exchanged
between the EtherCAT master and forced channels.
11 Errorbit 11 Reserve bit 11, currently not used
12 Errorbit 12 Reserve bit 12, currently not used
13
Voltage U
OUT
error Error in the supply voltage of outputs
14
Voltage U
IN
error Error in the supply voltage of system and inputs
15 Errorbit 15 Reserve bit 15, currently not used
Status messages of the modules
A module status byte is added to each module’s process
data (with the exception of safe I/O modules UR20-
*
-FSOE).
It describes the status of the module including the following
information:
Module status messages
Value Meaning
0x00 Plug-in station is undened
0x01 Plug-in station = module OK
0x80 Plug-in station empty, module has been removed
0x81 Incorrect module plugged in
0x82 Diagnosis available
