Independent Coverage and Control Across Conveyor Lines

Use RSio’s In-Series Diagnostics (ISD) capabilities to create individual safety zones on long-run conveyors common in distribution, 3PL, and material-handling environments. On one safety input, an ISD chain consisting of a rope pull brought in via ISD Connect and a series of e-stops provides stop coverage along the first conveyor line. A second safety input brings in another ISD chain of e-stops to protect a second line. A final switching device (FSD) connected to one of RSio’s safety-rated outputs controls the motor-driven rollers on the first line, while the second line’s final switching device is controlled by the safety controller via the CIP Safety connection. A hybrid port configured as a standard output drives a CL50 Column Light to provide system-status indication at a distance.

When any device in the first ISD chain is tripped, RSio drops the safety output to remove power from the FSD and stop the first conveyor. When a device in the second ISD chain is tripped, RSio reports the safety input status to the Safety PLC over the CIP Safety connection on the EtherNet/IP network, and the Safety PLC commands its final switching device to stop the second conveyor. ISD device-level diagnostics help maintenance quickly locate which device along either line needs attention.
