type
Display Cause
INTF
Internal
error
Errors determined by self monitoring:
• RAM memory test
• Check sum of correction factors
• Check sum of program code flash EPROM or RAM
EXTF
External
error
• Process signal “Analog Out” faulty
• Process signal “Analog In” faulty
• Process signal “Digital Out” faulty
• The 24 V DC load supply for the digital outputs is missing
BUSF1
Bus error 1 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:
• 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 X3B.
BUSF2
Bus error 2 Errors determined by self monitoring at the PROFIBUS DP
connection X3B
• Master monitoring has triggered
• Sign of life has failed
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.
RED
Redun-
dancy error
At module redundancy: The optical–fiber cable coupling between the
redundant AddFEMs has failed.
Compatibility test at the module redundancy in the LINK–UP state:
• The redundant AddFEMs were configured differently
• The master and the reserve modules have different firmware
version states
