11.2 NCK safety alarms for SINUMERIK 840D sl
27090 Error in crosswise Data comparison NCK-PLC %1 [%2], NCK: %3; %4<ALSI>
Parameter %1 = name of the system variable in which the error was detected
%2 = supplementary info, system variables - field index
%3 = supplementary information, comparison value, NCK
%4 = supplementary information, crosswise data comparison - field index
Explanation For cyclic crosswise data comparison between the NCK and PLC differences have occurred in the data that
are being compared. Parameter %1 specifies the incorrect system variable ($A_INSI, $A_OUTSI, $A_INSE,
$A_OUTSE or $A_MARKERSI) with field index %2.
Special cases:
● Display "Error for crosswise Data comparison NCK-PLC, $MN_PREVENT_SYNACT_LOCK[0], ..." means
that the SPL commissioning status is set differently in the NCK and PLC.
● Display "Error for crosswise Data comparison NCK-PLC, $MN_SPL_STOP_MODE[0], ..." means that the
SPL stop response (Stop D or E) is set differently in the NCK and PLC.
● Display "Error for crosswise Data comparison NCK-PLC, TIMEOUT[0], NCK: 0" means that there is a
critical communication error between the NCK and PLC - and crosswise data comparison cannot be
performed.
● Display "Error for crosswise Data comparison NCK-PLC, $MN_SAFE_SPL_USER_DATA[n], ..." means
that the user data are set differently in the NCK and PLC.
● Display "Error for crosswise Data comparison NCK-PLC, $A_FRDP_SUBS[n],
$A_FRDP_ERR_REAC[n], ..." means that the specified system variables are different in the NCK and
PLC.
Using parameter %4, a specific alarm message can be configured on the HMI for each of the listed system
variables:
0: Error SPL commissioning status ($MN_PREVENT_SYN-ACT_LOCK[0,1] - SPL_READY)
0: Error, SPL stop response ($MN_SAFE_SPL_STOP_MODE - STOP E)
0: Error, SPL user data ($MN_SAFE_SPL_USER_DATA - SafeUserData)
0: Error FSENDDP error response ($A_FSDP_ERR_REAC[n] - FSDP_ERR_REAC
0: Error FRECVDP error response ($A_FRDP_ERR_REAC[n] - FRDP_ERR_REAC
0: Error FRECVDP substitute values ($A_FRDP_SUBS[n] - FRDP_SUBS
1...64: Error in system variables $A_INSE[1...64]
65...128: Error in system variables $A_OUTSE[1...64]
129...192: Error in system variables $A_INSI[1...64]
193...256: Error in system variables $A_OUTSI[1...64]
257...320: Error in system variables $A_MARKERSI[1...64]
321...448: Error in system variables $A_INSE[65...192]
449...576: Error in system variables $A_OUTSE[65...192]
577...704: Error in system variables $A_INSI[65...192]
705...832: Error in system variables $A_OUTSI[65...192]
833...960: Error in system variables $A_MARKERSI[65...192]
Response Alarm display
A STOP D/E is initiated (this can be set using MD10097 $MN_SPL_STOP_MODE) on all of the axes with
safety functionality if the SPL commissioning phase (MD11500 $MN_PREVENT_SYNACT_LOCK[0,1] not
equal to 0) has been completed.
