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 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 4 output module consumes the
message, updates outputs, and produces a response. The response
has 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.
Refer to the table below for the word/bit definitions.

Output no load or overload fault (OFLT): - When the bit is set
(1), an output fault has occurred. OFLT0=outpout 0,
OFLT1=output 1, OFLT2=output 2, OFLT3=output 3.
Reserved
Output Power Fault (OPWR): When the bit is set (1),
Auxiliary Power is not present.

Output bits: When the bit is set (1), the output will be turned
on. Bit 00=output 0, bit 01=output 1, bit 02=output 2, bit
