Cold-junction compensation (CJC) circuits are implemented for accurate thermocouple temperature readings. FOUNDATION Fieldbus and PROFIBUS PA connectivity allows deterministic loop execution and direct device-level communication, supporting 4-20 mA HART loop integration for hybrid analog-digital control.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eQ: How is hot-swapping of I\/O modules handled?\u003cbr\u003eA: I\/O modules support controlled hot-swap under duplexed operation; only the module in the inactive channel may be replaced without interrupting the active control channel.\u003c\/p\u003e\n\u003cp\u003eQ: What is the expected failover delay between primary and backup CPUs?\u003cbr\u003eA: Duplexed failover occurs within a few milliseconds, limited by I\/O scan synchronization and communication latency on the backplane.\u003c\/p\u003e\n\u003cp\u003eQ: Can the system firmware be updated in the field?\u003cbr\u003eA: Firmware updates are supported via redundant CPU channels.
