Diagnostic message Fault
code
Meaning Remedy
Module is defective 100
H
Possible causes:
• Electromagnetic interference has
exceeded limits.
•
The F-module has detected an inter-
nal error and has reacted in a safety-
related manner.
• Eliminate the interference. The
module must then be pulled and
plugged, or the power switched
OFF and ON.
•
If the F-module cannot be put back
into operation, consider replacing it.
Watchdog tripped 103
H
Possible causes:
• Electromagnetic interference has
exceeded limits.
•
The F-module has detected an inter-
nal error and has reacted in a safety-
related manner.
• Eliminate the interference. The
module must then be pulled and
plugged, or the power switched
OFF and ON.
•
If the F-module cannot be put back
into operation, consider replacing it.
Internal supply voltage of the
module failed
104
H
Internal voltage is too low. Replace the F-module.
Common mode error 118
H
Voltage between two input channels is
too high.
Correct the input wiring.
Invalid/inconsistent firmware
present
11B
H
The firmware is incomplete and/or firm-
ware added to the F-module is incompat-
ible. This leads to errors or functional
limitations when operating the F-module.
•
Perform a firmware update for the
F-module. Note any error messag-
es.
•
Use only firmware versions re-
leased for this F-module.
Diagnostics memory over-
flow
13E
H
Overflow of the diagnostics memory. It
was not possible to send all pending
diagnostics. This error can lead to deacti-
vation of the F-module and even to switch
off/on of the supply voltage.
Remedy the cause of the diagnostics
surge.
Analog input signal not rec-
orded unique
304
H
Measured values from the sensor are not
plausible.
Possible causes:
• Increased EMC
•
F-module defective
Check the interaction between the F-
module and the sensor.
Internal sensor supply short-
circuit to P
306
H
Possible causes:
• Short-circuit of internal sensor supply
to P
Check the process wiring.
Overload or internal sensor
supply short-circuit to M
307
H
• The internal sensor supply is over-
loaded.
•
Missing or insufficient supply voltage
L+.
• Eliminate the short-circuit in the
process wiring.
•
Check the supply voltage L+ on the
BaseUnit.
• Check the BaseUnit.
