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 output data as follows:
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 - a master initiates communication by sending its polled I/O
message to the module. This 16 output module consumes the
message, updates outputs, and produces a response. The response
has output data, output faults, and contains the status of the Auxiliary
power.
Change-of-State - productions occur when an output changes or a
fault condition occurs. If no output 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.
