8 ArmorBlock MaXum 12 Input/ 4 Output Module Series B

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.
