Communicate With Your ArmorBlock MaXum I/O
Module
This ArmorBlock module’s I/O is exchanged with the master through
a poll, change-of-state, or cyclic connection.
The module consumes and produces I/O data as follows:
Cyclic - allows configuration of the block as an I/O client. The block
will produce its I/O cyclically at the rate configured.
Polled - a master initiates communication by sending its polled I/O
message to the module. The 8 input module cans the inputs and fault
bits producing a response that reflects their status.
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 module is alive
and ready to communicate.
Refer to the table below for the word/bit definitions.
