Communicate With Your ArmorBlock MaXum I/O Module
This ArmorBlock module’s I/O is exchanged with the master through
a cyclic, poll, or change-of-state 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 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. 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 - 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.
