Communicate with Your Module
Refer to this section only if you are not using RSLogix5000 to communicate with your
I/O board.
This board’s I/O is exchanged through a cyclic, or change-of-state connection.
Cyclic — The block will produce and consume its I/O cyclically at the rate configured.
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 connection originator that the
I/O board is alive and ready to communicate. Consumption occurs when data changes and
the connection originator produces new output data to the I/O block.
