6 ArmorBlock LP2 2 Sinking Input Module

Publication 1792D-5.43 - July 1999

Polled - a master initiates communication by sending its polled I/O

message to the module. The 2 input module scans the inputs producing a

response that reflects their status.

Change of state - productions occur when an input changes. If no input

change occurs within the expected packet rate, a heartbeat production

occurs. This heartbeat production tells the scanner module that the module

is alive and ready to communicate.
