Designed for fail-safe CPU applications meeting IEC 61508 (SIL 3) and ISO 13849-1 (PLe\/Cat. 4) standards, the unit processes safety-critical signals while continuously monitoring execution timing and hardware\/software self-tests. The controller integrates four 10\/100BaseT RJ-45 Ethernet ports via an internal switch for safety-rated peer-to-peer networking, EtherNet\/IP communications, and programming. Non-safety serial communications are supported through RS-485 interfaces, including Modbus RTU Slave on COMM1 and GuardPLC ASCII\/High-Speed Safety Protocol (HSP) on COMM3.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eIntegrated on-board safety I\/O including 24 digital inputs, 8 digital outputs, 8 safety-related analog
