8 ArmorBlock MaXum 8 Input / 8 Output Module Series B

Publication 1792D-IN020B-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 I/O 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. The 8 input / 8 output module consumes the message,

updates outputs, and produces a response. The response has input data, input

faults, 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. Consumption occurs when data changes and the master

produces new output data to the I/O block.

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