In order to parameterize alarm 27090, file ALSI_xx.com must be incorporated in data han-
dling and announced in HMI via MBDDE.INI in section[IndexTextFiles]
ALSI=f:\dh\mb.dir\alsi_ .
The definition of this file can be changed by the machine OEM, in order to incorporate
additional text passages in the alarm that make sense for their system. If the file definition
shall be changed, the new file must be announced in the system via MBDDE.INI.
Via MD $MN_SAFE_ALARM_SUPPRESS_LEVEL the display of alarm 27090 can be
influenced: MD $MN_SAFE_ALARM_SUPPRESS_LEVEL = 2 : Alarm 27090 is only dis-
played for the data difference found first.
Reactions: - 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: Analyze the value displayed and evaluate DB18: SPL_DELTA on the PLC side.
Find the difference between the monitoring channels. Possible causes:
• Incorrect wiring
• Incorrect SPL
• Incorrect assignment of the axial SGEs to internal interface $A_OUTSI
• Incorrect assignment of the axial SGAs to internal interface $A_INSI
• 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 Con- Clear alarm with the RESET key. Restart part program
tinuation:
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.
Reactions: - 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 Con- Clear alarm with the RESET key. Restart part program
tinuation:
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 chan-
nel specified in %1 (NCK or PLC). The other monitoring channel did not send a new data
packet within this time.
Reactions: - Alarm display.
