Communicate With Your ArmorBlock MaXum I/O Module

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

a cyclic, poll, or change-of-state 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 12 input / 4 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.
