The hardware identifier of the module or submodule which sends the process
event.
The identifier must belong to a hardware component in the currently loaded
project.
•
UINT16 in_Channel:

PLCSIM Advanced assigns a unique consecutive number to each interrupt
event.
According to PROFINET standard the sequence number is 10 bits wide (1 to
7FF ). When the highest number is reached the numbering starts again at 1.
