Assignment Meaning Remedy
Inconsistent iParame‐
ters (iParCRC error)
4B
H
F-module The F-module has detected inconsistent
iParameters.
Check the parameter assign‐
ment.
F_Block_ID not suppor‐
ted
4C
H
F-module The F-module has detected an incorrect
block ID.
Check the parameter assign‐
ment of the PROFIsafe driver.
Transmission error: In‐
consistent data (CRC er‐
ror)
4D
H
F-module The F-module has detected a CRC error.
Possible causes:
• The communication between F-CPU
and F-module is disturbed.
• Electromagnetic interference is too
high.
• An error has occurred in the sign-of-
life monitoring.
• Check the communication
connection between F-
module and F-CPU.
• Eliminate the electromag‐
netic interference.
Transmission error:
Timeout (monitoring
time 1 or 2 expired)
4E
H
F-module The F-module has detected a timeout.
Possible causes:
• The F-monitoring time is set incorrect‐
ly.
• There is a bus fault.
• Check the parameter as‐
signment.
• Ensure that communica‐
tion is functional.
Module is defective 100
H
F-module Possible causes:
• Electromagnetic interference is too
high.
• The F-module has detected an inter‐
nal fault and responded to it in a safe‐
ty-related manner.
• Wrong terminal block
• Eliminate the interference.
Removal and insertion of
the F-module or a POWER
OFF – POWER ON is then
required.
• Use a suitable terminal
block.
• Replace the F-module.
Watchdog tripped 103
H
F-module Possible causes:
• Electromagnetic interference is too
high.
• The F-module has detected an inter‐
nal fault and responded to it in a safe‐
ty-related manner.
• Wrong terminal block
• Eliminate the interference.
Removal and insertion of
the F-module or a POWER
OFF – POWER ON is then
required.
• Replace the F-module.
Internal supply voltage
fault
104
H
F-module Internal voltage is too low. Replace the F-module.
Invalid/inconsistent
rmware present
11B
H
Channel The rmware is incomplete and/or rm‐
ware extensions of the F-module are in‐
compatible. This leads to errors or func‐
tional limitations when operating the F-
modules.
• Perform a rmware up‐
grade of the F-module and
watch out for any error
messages.
• Use only the rmware ver‐
sions released for this F-
module.
Diagnostic queue over‐
ow
13E
H
F-module Overow of the diagnostics memory. Not
all pending diagnostics information could
be sent. This error can lead to disabling of
the F-module until the supply voltage is
switched o/on.
Correct the cause of the diag‐
nostics surge.
