This example describes how to use a PLC to control the “wake-up” and passing of tracking data to the most upstream zone of a ConveyLinx controlled conveyor
For this example, the PLC must establish a connection with Module A. When PLC is ready to transfer a Carton from the PLC controlled conveyor to the Upstream Zone of the MDR Conveyor, the PLC logic must:
- Write a “4” into Set Status for Upstream Induct register. This will cause the upstream zone of Module A to run to accept Carton.
- When Carton clears PE-1, write tracking data to Set Induct Tracking Forward Direction Word 1 and Set Induct Tracking Forward Direction Word 2
- When Carton clears PE-1, write a “1” to Set Status for Upstream Induct register. When Module A sees this register change to “1”, it knows that the tracking data written to Set Induct Tracking Forward Word 1 and Set Induct Tracking Forward Word 2 is valid and when the Carton reaches the sensor in its upstream zone, the tracking data will be correctly inducted
