Errors determined by self monitoring:
•
error RAM memory test
•
Check sum of correction factors
•
Check sum of program code flash EPROM or RAM
•
Process signal "Analog Out" faulty
•
error Process signal "Analog In" faulty

Process signal "Digital Out" faulty
•
The 24 V DC load supply for the digital outputs is missing
Errors determined by self monitoring at the PROFIBUS DP
connection X3A:
•
Master monitoring has triggered
•
Sign of life has failed
Parameterization error via PROFIBUS DP connection X3A:
•

values.
•
At 2–channel configuration: The received parameter values
deviate from the configuration via the PROFIBUS DP connec-
tion X3B.
Errors determined by self monitoring at the PROFIBUS DP
connection X3B
•

Parameterization error via PROFIBUS DP connection X3B:
•
The received configuration message contains invalid parameter
values.
•
At 2–channel configuration: The received parameter values
deviate from the configuration via the PROFIBUS DP connec-
tion X3A.
