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 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 - 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.
Refer to the table below for the word/bit definitions.
