Communicate With Your ArmorBlock MaXum I/O

Module

This ArmorBlock module’s I/O is exchanged with the master through

a poll, change-of-state, or cyclic connection.

The module consumes and produces I/O data as follows:

Cyclic - allows configuration of the block as an I/O client. The block

will produce its I/O cyclically at the rate configured.

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

message to the module. The 8 input module cans the inputs and fault

bits producing a response that reflects their status.

Change-of-State - productions occur when an input changes or a

fault condition occurs. If no input or fault condition 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.

Refer to the table below for the word/bit definitions.
