Communications Gateway Module (CGM)
Quick Start: The system needs a minimum of 3 bits controlled by the PLC to become operational (Heartbeat,
Enable PLC Control, and Activate System). As seen below, the Heartbeat from the PLC mirrors the heartbeat from
the InvisiPac. The InvisiPac will change the heartbeat state every 3 seconds. Next, the PLC will need to bring
"Enable PLC Control" and "Activate System" bits high. If there are no alarms present and the "Immediate Stop" bit
is low, the system will begin heating any devices that are enabled on the system.

Immediately Stop System – Stops the system on the rising edge of this bit, regardless of the Activate System
status. The system will set a bit indicating why the system turned for reasons other than pulling "Activate System"
low.
