Table 7-111 Elimination of error at "alive and well" counter status "2"
Value Cause
byte 1
1 In the temperature measure‐
ment operating mode, an in‐
put voltage is too high. The
hardware may become dam‐
aged/destroyed as a result.
2 Reserved
3 Overload at the outputs
4 Incorrect operating mode se‐
lection, e.g. temperature
measurement at the analog
outputs.
5 Internal error, system error
6 Overrange at the inputs
7 Overrange at the outputs
The analog outputs retain their last specified value.

Diagnostics via Status Bytes 0/1
In Status Byte 0, the set operating modes are reflected e.g. "0x55" if Control Byte 0 = 0x55
has been specified.
In the event of an error, the error bit is set in Status Byte 1 (bit 7). In the event of an error in
one channel, all channels are disabled.

Remedy
It is essential that a Pt100 element is
connected to terminals 3-4 or 7-8.
The module must be restarted with Pow‐
er ON following elimination of the error.
-
Check the loads at the analog output.
The module must be restarted with Pow‐
er ON following elimination of the error.
If selected correctly, the module switches
to cyclic operation.
The firmware has detected a system er‐
ror, this status can only be exited by
means of a switch-on / switch-off.
Check input circuit and adjust, if required.
Correct values in the user program.
