Thai Robotics and Automation is pleased to present our PLC I/O Redundant System, designed to keep production running even when the primary I/O network is damaged.
The system uses a wired DeviceNet network as the primary path, backed by an EtherNet/IP network over WiFi. If the main cable fails, a single selector switch wired to a PLC input moves I/O to the WiFi path immediately. No rewiring and no program download are required.
Key benefits:
✅ Less downtime: production continues while the cable is repaired
✅ Simple, fast switchover with one selector switch
✅ Proven, standard modules: spares are easy to source
