Heartbeat – Explained

Thrive refers to a “heartbeat” signal to determine line up or line down.

The heartbeat is an electrical signal tied directly into the PLC to terminal 1 or terminal 5 on the PLC input card.

The heartbeat is ran directly from the manufacturing line and will give the PLC a “0” or “1” to determine line up or line down.

Example:

The signal could be tied into a conveyor system. When the conveyor stops the line is considered down and we receive a “0” to the heartbeat input. When the conveyor is running we receive a “1” which tells us the line is currently running.
