Find the difference between the monitoring channels. Possible causes:
• Incorrect wiring
• Incorrect SPL
• Incorrect assignment of axial SGEs to the internal interface $A_OUTSI
• Incorrect assignment of axial SGAs to the internal interface $A_INSI
• Incorrect assignment of SPL SGE's to the external interface $A_INSE
• Incorrect assignment of SPL SGA's to the external interface $A_OUTSE
Clear alarm with the RESET key. Restart part program
Error in data cross check NCK PLC, stop of %1
%1 = Extension indicating the monitoring channel that triggered the stop
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.
- Alarm display.
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.
Clear alarm with the RESET key. Restart part program
Communication broken off during NCK PLC data cross check, error detected by %1
%1 = Extension indicating the monitoring channel that detected the error
The delay time (10s) for communication monitoring was exceeded in the monitoring chan-
nel specified in %1 (NCK or PLC). The other monitoring channel did not send a new data
packet within this time.
- Alarm display.
Do not start the SPL again. Check the system components (the PLC must have the cor-
rect version of FB15 and DB18).
Switch control OFF - ON.
Checksum error NCK-SPL, %1, %2, %3
%1 = Extension indicating the type of error
%2 = Extension indicating the reference variable
%3 = Extension indicating the actual variable
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 cor-
rupted. 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.
- Alarm display.
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.
Switch control OFF - ON.
