The display of Alarm 27090 is influenced via the MD
$MN_SAFE_ALARM_SUPPRESS_LEVEL: MD
$MN_SAFE_ALARM_SUPPRESS_LEVEL = 2 : Alarm 27090 is only displayed
for the first data difference found.
Response Alarm display
A STOP D/E is initiated (this can be set using MD $MN_SPL_STOP_MODE)
on all of the axes with safety functionality if the SPL commissioning phase (MD
$MN_PREVENT_SYNACT_LOCK[0,1] not equal to 0) has been completed.
Remedy Analyze the displayed value and evaluate DB18: SPL_DELTA on the PLC side.
Find the difference between the monitoring channels. Possible causes:
-

Program continuation Clear the alarm with the RESET key. Restart part program.
27091
Error in data cross check NCK-PLC, STOP of %1
Parameter %1 = supplementary information about the monitoring channel that has initiated
the stop
Explanation 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). Alarm 27090 provides additional information
about the reason for the Stop D/E.
Response Alarm display
A STOP D/E has been initiated (this can be set using MD
$MN_SPL_STOP_MODE) on all of the axes with safety functionality if the SPL
commissioning phase (MD $MN_PREVENT_SYNACT_LOCK[0,1] not equal to
0) has been completed.
Remedy Evaluate the alarm parameters of Alarm 27090 and correct 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 continuation Clear the alarm with the RESET key. Restart part program.
27092
Communications interrupted for crosswise data comparison, NCK-
PLC, error detected by %1
Parameter %1 = supplementary information about the detecting monitoring channel
Explanation The delay timer stage (1s) for the communication monitoring has been
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.
Response Alarm display
A STOP D/E has been initiated (this can be set using MD
$MN_SPL_STOP_MODE) on all of the axes with safety functionality if the SPL
commissioning phase (MD $MN_PREVENT_SYNACT_LOCK[0,1] not equal to
0) has been completed.
A timer stage of 5 sec is started – after it has expired
- the external NCK-SPL outputs are deleted
- the PLC goes to stop.
Remedy Do not start the SPL again. Check the system components (PLC must have the
correct version of FB15 and have DB18).
Program continuation Power-down the control and power-up again.
