Abstract

See full text

Wiring work without requiring a safety PLC is simplified even when a plurality of safety switches having a lock function are arranged. The plurality of safety switches are cascade-connected to a wiring unit. The wiring unit supplies power received via the power input unit (a VCC terminal or a GND terminal) to the plurality of safety switches. The wiring unit performs through-output of an OSSD input received from the most downstream safety switch to the outside of the wiring unit. The wiring unit outputs upstream-facing communication data COM (a lock input or the like) based on a lock instruction (LOCK). The wiring unit receives downstream-facing communication data COM (such as bundle data of AUX outputs) and outputs the communication data COM as individual AUX outputs.
