Communicate with the 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.
ATTENTION: Make sure all connectors and caps are securely tightened to
properly seal the connections against leaks and maintain IP enclosure
type requirements.
