Publication 1792D-IN004B-EN-P - August 2000
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 device - 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 device - 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.
