I. Core Positioning

EPI3382 is the communication and control hub of the Tricon system, installed in the key slots of the mainframe frame; it adopts the TMR triple redundancy architecture, integrating dual Ethernet ports + local I/O + real-time processor, responsible for data exchange between Tricon and DCS/SCADA/upper computer/third-party devices, and can also expand local I/O and execute safety interlock logic. It is the core for SIS system interconnection and edge control.
