- Incorrect assignment of the SPL SGEs to external interface $A_INSE
- Incorrect assignment of the SPL SGAs to external interface $A_OUTSE
- Different SPL startup status set in NCK and PLC
- Different SPL stop reaction set in NCK and PLC
Program Clear alarm with the RESET key. Restart part program
Continuation:
27091 Error in data cross check NCK-PLC, stop of %1
Parameters: %1 = Extension indicating the monitoring channel that triggered the stop
Definitions: The monitoring channel specified in %1 (NCK or PLC) has triggered a stop D or E (depending on the
parameterization in MD $MN_SAFE_SPL_STOP_MODE). The alarm 27090 provides further
information about the cause for the stop D/E.
Reaction: Alarm display.
Trigger a STOP D/E (settable via MD $MN_SPL_STOP_MODE) on all axes with safety functionality,
as soon as the SPL start-up phase (MD $MN_PREVENT_SYNACT_LOCK[0,1] unequal to 0) is
completed.
Remedy: Evaluate the alarm parameters of alarm 27090 and amend the SPL, or check the I/O modules/wiring
or the internal SPL interfaces to the safety monitoring channels in the NCK and drive 611D.
Program Clear alarm with the RESET key. Restart part program
Continuation:
27092 Communication broken off during NCK PLC data cross check, error
detected by %1
Parameters: %1 = Extension indicating the monitoring channel that detected the error
Definitions: The delay time (1s) for communication monitoring was exceeded in the monitoring channel specified
in %1 (NCK or PLC). The other monitoring channel did not send a new data packet within this time.
Reaction: Alarm display.
A timer of 5 secs is started, after the expiry of which
- the external NCK SPL outputs are deleted
- the PLC changes to stop.
Remedy: Check the system components (the PLC must have the correct version of FB15 and DB18).
Program Switch control OFF - ON.
Continuation:
27093 Checksum error NCK-SPL, %1, %2, %3
Parameters: %1 = Extension indicating the type of error
%2 = Extension indicating the reference variable
%3 = Extension indicating the actual variable
Definitions: A checksum error has occurred in the NCK SPL. The file /_N_CST_DIR/_N_SAFE_SPF was
subsequently modified. The safe programmable logic (SPL) in the NCK may be corrupted. Parameter
%1 indicates the type of modification:
- %1 = FILE_LENGTH: the file length has changed.
- %1 = FILE_CONTENT: the file contents have changed.
%2 specifies the reference variable (file length, checksum of file contents), %3 specifies the actual
variable which is calculated cyclically.
Reaction: Alarm display.
Remedy: Check the file and the time of the last modification to the file. Reload the original file and start the
monitoring system again with a Power On.
Program Switch control OFF - ON.
