Communicate with Your ArmorBlock Module
This ArmorBlock module acts as a slave in a master/slave environment.
It is both a “polled device” and a “change of state device.”
When configured as a polled device, a master initiates communication
by sending its polled I/O message to the ArmorBlock module. The 2
input/2 output module scans the inputs and fault bits producing a
response, and consumes the message, updates outputs, and produces a
response that reflects their status.
When configured as a “change of state” device, productions occur
when an input changes, or an output fault occurs. If neither has
occurred within the “expected packet rate,” a heartbeat production
occurs. This heartbeat production tells the scanner module that the
ArmorBlock module is alive and ready to communicate.
