I/O Data Assembly Maps

Read this section for information about how to communicate with your
module.

I/O messages are sent to (consumed) and received from (produced) the I/O
modules. These messages are mapped into the processor’s or scanner’s
memory. Each module produces 1, 8 or 20 bytes of input data based on which
produced assembly is selected. The default setup is 20 bytes.
It consumes 1, 8 or 20 bytes of I/O data (scanner Tx).

Where:

Pt = value of the I/O point,

PNB = Produced Network Bit,

PM = Peer Missing (a 1 indicates the absence of a configured peer)

Owned = Owned by a master.
When set to 0, the module is producing data without a master.
When set to 1, the module is producing while being owned by a master.

LogicEn = Logic Enabled (0 = logic disabled, 1 = logic enabled)
