Fig. 3-61: PLC trace: Adding variables
Note
By default, PLC addresses are restricted to the address range of the smallest
PLC.
To remove this restriction if you are using a more powerful PLC and want to use
the addresses in SINUMERIK Integrate, increase the related values in the trigger
DB (DB239 in SINUMERIK Integrate Standard) in DW8 for inputs, DW10 for
outputs, DW12 for flags, DW14 for timers, and DW16 for counters, to the
available address ranges. Restarting the PC that holds the client is necessary.
Warning
Using the trigger DB with an increased address range can cause the PLC to stop
when you use the higher addresses in SINUMERIK Integrate configurations, and
this address range is not really available in the connected PLC.
