AirTronic - Operation

Remote I/O Mode

Direct connection to Rockwell/Allen-Bradley
Remote I/O can be made via the Serial Node
Adapter or Serial Node Adapter +. Connect the
Allen-Bradley (AB) RIO cable directly to the
motherboard of the Node Adapter. If the AirTronic
Display Module is in the same motherboard as the
Serial Node Adapter, no further connection is
necessary. If the Display Module is located in a
different motherboard, the local serial bus must be
connected via the connector labeled "Serial Bus."

In general, the I/O data is:

Block Transfer Writes: Channel 1 and 2 Setpoints
and tolerances for over and under flow alarms

Block Transfer Reads: Channel 1 and 2 actual
flows, system input air pressure at the input of flow
block, status indicators for Display module in
Local Setpoint mode, and Channel 2 in Slave
Mode.

Discrete Inputs: Seven status conditions for each
Display Module are provided.

Discrete Outputs: One trigger bit for each channel
for operating a trigger valve in the flow line output.

The detailed PLC I/O Tables for these signals are
located in the Serial Node Adapter Manual, LN-
9238-02 and later versions.

This is not the same bus that is
