Pass-Through Events: Y #Pass event messages to processor
The following illustration shows the basic idea of the event pass-through
functionality. When the module receives the event from the remote device, it will
build block 9903, which will be copied to the processor at the configured memory
address:

Event Pass-Through Block Format
The block that is copied from the module to the processor has the following
format. Each block can contain up to 4 events. The number of events per block
will typically depend on the rate between how fast the module receives the
events and how fast these can be passed to the processor (typically depends on
the processor scan rate).
