Table 7-111 Elimination of error at "alive and well" counter status "2"
Value
byte 1
Cause Effect Remedy
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.
The "PNFault" LED is activated.
The outputs are disabled.
1)
The value 0x80 is stored in Status Byte
1.
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.
2 Reserved - -
3 Overload at the outputs The "PNFault" LED is activated.
The outputs are disabled.
1)
The value 0x80 is stored in Status Byte
1.
Check the loads at the analog output.
The module must be restarted with Pow‐
er ON following elimination of the error.
4 Incorrect operating mode se‐
lection, e.g. temperature
measurement at the analog
outputs.
Selection of operating mode is rejected, If selected correctly, the module switches
to cyclic operation.
5 Internal error, system error The "PNFault" LED is activated.
The outputs are disabled.
1)
The value 0x80 is stored in Status Byte
1.
The firmware has detected a system er‐
ror, this status can only be exited by
means of a switch-on / switch-off.
6 Overrange at the inputs Check input circuit and adjust, if required.
7 Overrange at the outputs Correct values in the user program.
1)
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.
