Communicate with Your Module

This module’s I/O is exchanged with the master through a cyclic, polled, or
change-of-state connection.
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 module consumes the message, updates outputs, and
produces a response. The response has input data.
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 Module Data Definitions table for more information.
