Error in data cross check NCK-PLC, %1[%2], NCK: %3; %4<ALSI>
%1 = Name of system variable in which the error was detected
%2 = System variable array index extension
%3 = NCK comparison value extension
%4 = Cross-check array index extension
Differences in the compared data have occurred in a cyclic data cross check between
NCK and PLC. Parameter %1 specifies the erroneous system variable ($A_INSI,
$A_OUTSI, $A_INSE, $A_OUTSE or $A_MARKERSI) with error index %2.
Special cases:
• Alarm "Error in NCK-PLC data cross check, $MN_PREVENT_SYNACT_LOCK[0], ..."
means that the SPL startup status has been set differently in the NCK and PLC.
• Alarm "Error in NCK-PLC data cross check, $MN_SPL_STOP_MODE[0], ..." means that
the SPL stop reaction (Stop D or E) has been set differently in the NCK and PLC.
• Alarm "Error in NCK-PLC data cross check, TIMEOUT[0], NCK: 0" means that the com-
munication between NCK and PLC is generally disturbed and that a data cross check can
no longer be performed.
With data cross-check errors on system variables $A_INSE, the hardware assignment
parameterized in MD $MN_SAFE_IN_HW_ASSIGN[0...7] is displayed in addition to the
affected system variables in alarm parameter %1, so that the affected hardware connec-
tion is shown directly by the specifications in the alarm line.
Example: Error in NCK-PLC data cross-check, DMP 04.03 Bit 01=$A_INSE[2], NCK: 1;
The specifications in the example (04.03) correspond to the entries made in the machine
data $MN_SAFE_IN_HW_ASSIGN[0...7] for the mentioned system variable.
They specify:
DMP 04.xx The drive number of the affected terminal block (value range = 01...21).
DMP xx.03 Module number of the input module (value range = 01...08).
The indicated numbers are represented as hexadecimal numbers, same as in MD
$MN_SAFE_IN_HW_ASSIGN[0...7].
Same as with the numbering of the inputs on the DMP modules, the bit numbers begin
with value 0 (value range = 00...15).
When assigning the SPL inputs to the NC onboard inputs, the extended alarm text is as
follows:
Error in NCK-PLC data cross-check, NC-Onboard-In 01=$A:INSE[1], NCK: 1; 2.
With parameter %4 a specific alarm message can be configured on HMI for all listed sys-
tem variables:
%4 = 0: Error SPL startup status ($MN_PREVENT_SYNACT_LOCK[0,1] -
DB18.DBX36.0) or different stop reaction ($MN_SAFE_SPL_STOP_MODE -
DB18.DBX36.1).
%4 = 1.... 64: Error in system variable $A_INSE[1...64]
%4 = 65...128: Error in system variable $A_OUTSE[1...64]
%4 = 129...192: Error in system variable $A_INSI[1...64]
%4 = 193...256: Error in system variable $A_OUTSI[1...64]
%4 = 257...320: Error in system variable $A_MARKERSI[1...64]
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.
