Diagnostics/commissioning

The system variables $A_INSIP(D), $A_OUTSIP(D), $A_INSEP(D) and $A_OUTSEP(D), and
$A_MARKERSIP(D) are only used for diagnostics and commissioning 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 CDC on the PLC side
from the NC. This helps when commissioning the SPL:
● Crosswise data comparison function can be temporarily bypassed
● 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 during the commissioning phase.
In order to allow the SPL to be commissioned without the crosswise data comparison 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 $AOUTSED[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]= $A_MARKERSIPD[1]
IDS = 10 DO $A_MARKERSID[2]= $A_MARKERSIPD[2]
