Core Functions

Supports full IEC61131-3 programming languages(LD/FBD/ST/SFC/IL/CFC); dual-CPU hot standby redundant configuration with 140CHS11000 redundant module, fault switchover＜80ms without production halt; multi-loop high-precision PID regulation, fast interrupt & high-speed counter processing; complete system self-diagnosis and fault event record storage; online program modification; standby CPU hot-swap available during system running; large data interaction with upper SCADA/DCS via fiber Ethernet.

Application Scenarios

Large petrochemical refining whole-process control, thermal power main boiler & turbine control, large-scale municipal sewage/water supply plant, metallurgy smelting continuous production line, coal mine centralized transportation control, offshore platform auxiliary critical automation system.

Operation & Maintenance Notes

Multimode fiber Ethernet needs matched multimode fiber jumper; programming download requires EcoStruxure Control Expert V8.0 or above; PCMCIA memory card for full program backup to avoid power-down data loss; inspect RUN/FAULT/COM indicator status regularly; replace built-in lithium battery every8~10 years to prevent parameter loss.
