Diagnostics/commissioning

The system variables $A_INSIP(D), $A_OUTSIP(D), $A_INSEP(D) and $A_OUT-
SEP(D), and $A_MARKERSIP(D) are only used for diagnostics and commission-
ing the NCK–SPL. These system variables represent the input data for crosswise
data comparison on the PLC side. They are updated every IPO cycle. They can
also be used to access the crosswise data comparison on the PLC side from the
NC. This helps when commissioning the SPL:
S Crosswise data comparison function can be temporarily bypassed
S NCK–SPL can be simulated to the process and to the NCK monitoring channel
To do this, the relevant PLC images are written to the variables $A_OUTSED
and $A_OUTSID as long as there is no NCK–SPL. This means that the NCK–
SPL can be commissioned step–by–step. This data may only be accessed dur-
ing the commissioning phase.
In order to allow the SPL to be commissioned without the crosswise data compari-
son function constantly responding, the following "minimum NCK–SPL" can be
installed in this phase:
; Simulate external SPL interface
IDS = 03 DO $A_OUTSED[1]
IDS = 04 DO $A_OUTSED[2]
; Simulate internal SPL interface
IDS = 07 DO $A_OUTSID[1]
IDS = 08 DO $A_OUTSID[2]
; Emulate PLC markers (for all markers used in the PLC)
IDS = 09 DO $A_MARKERSID[1]
IDS = 10 DO $A_MARKERSID[2]
; End of program
