8 ArmorBlock MaXum 8 Output Module Series B

Publication 1792D-IN003B-EN-P - September 2000

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 output data as follows:

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

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

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

message to the module. This 8 output module consumes the

message, updates outputs and produces a response. The response

has output faults and the status of the Auxiliary power.

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 I/O module is

alive and ready to communicate.

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