ArmorBlock MaXum 8 Input / 8 Output Module
Publication 1792D-5.20 - October 1998
Polled device - a master initiates communication by sending its polled I/O
message to the module. The 8 input / 8 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.
