Core Functions

Execute user control program (LD/FBD/ST/IL/CFC languages); dual-CPU hot standby redundant control with seamless switchover <100ms when main CPU fault; local+remote I/O data collection & analog PID closed-loop regulation; multi-network data exchange with DCS/SCADA; onboard system fault self-diagnosis & event log storage; online program modification & remote diagnosis via Ethernet; support FDR faulty module online replacement under running system。

Application Scenarios

Petrochemical refining process control, thermal power plant boiler & turbine auxiliary control, water treatment large-scale automation, cement production line centralized control, metallurgy smelter continuous process system, offshore auxiliary equipment PLC control。

Operation & Maintenance Notes

Redundant configuration allows hot swap of standby CPU without system shutdown; adopt shielded CAT5E cable for all Ethernet wiring; program download exclusively by Unity Pro V7.0+ software; regularly inspect front RUN/FAULT/COM LED indicators and system fault records; PCMCIA memory card used for program backup to avoid data loss after power failure。
