27251 PROFIsafe: F-module %1, %2 reports error %3
Parameter %1 = PROFIsafe address or name
%2 = signaling components (master/slave)
%3 = error detection
Explanation There is a communication error between the F-master and the specified F- module.
The component that detected the error is displayed in %2:
● Master: Error was detected in the F-master.
● Slave: Error was detected in the F-slave.
If the alarm was detected in the "F-slave" then the following error IDs (%3) are possible:
● CN: An error was discovered in the telegram sequence.
● CRC: A CRC error was detected
● TO: The parameterized communication timeout has been exceeded or the PROFIsafe address was
incorrectly set.
● LBF: Communication error, telegram mirroring
If the alarm was detected in the "F-master" then the following error IDs (%3) are possible:
● CN: An error was detected in the telegram sequence
● CRC: A CRC error was detected
● TO: The parameterized communication timeout has been exceeded
● IO: F-slave sends empty telegrams
● TF: Timer overflow - all of the specified values for %3 can, depending on the error profile, also be displayed
in a combination.
Response Mode group not ready
NC start disable in this channel
Interface signals are set
Alarm display
NC stop for alarm
A STOP D/E is initiated (this can be set using MD10097 $MN_SPL_STOP_MODE) on all axes with safety
functionality. Failsafe values were activated for the specified module.
Remedy Check the I/O bus.
Restart the F-slave modules.
Restart the NCK/PLC
Check the logical basis addresses (the direct and indirect addressing should be taken into consideration) to
see if they have been used in other parts of the PLC configuration.
Additional diagnostic options
● Prevent the user program from being executed
● General PLC reset and load the basic program from the toolbox
Program con‐ Clear the alarm with the RESET key. Restart the part program.
