Material Composition FR4 flame retardant PCB with conformal acrylic coating 32-bit RISC processor chip Flash memory and RAM memory chips FTE network isolation transformers Watchdog monitoring circuit TVS surge protection components ABS flame retardant front panel Multi-color LED indicators for status, network, fault and redundancy Metal rack locking buckle
Structural Features Standard Series C plug-in controller module form factor. Front panel integrates multiple LED indicators for power, run, fault, redundancy and FTE link status. Side anti-misalignment notch prevents reverse insertion. Rear gold finger contacts connect to rack backplane bus. Two FTE RJ45 ports are arranged on front panel for redundant network connection. Lock clip fixes module firmly on controller rack slot.
Working Principle Engineering workstation downloads control logic, PID parameters and alarm configuration into flash memory of CPCNT01. The processor runs logic program in fixed scan cycle. It reads field process data from I/O modules via backplane bus, executes control calculation, and sends output command to I/O modules. It synchronizes all logic data and real-time variable with redundant partner controller. When primary controller fails, redundant controller takes over control automatically without bumping process. It sends alarm, SOE and process data to Experion server via FTE network.
Installation Requirements Power off controller rack before inserting module. Align anti-misalignment notch and insert into controller slot, lock buckle. Connect FTE A and FTE B Ethernet cable to two RJ45 ports. Configure controller address and redundant pair in Experion Control Builder. Download control logic and parameter set. Power on rack and verify run status, redundancy synchronization status. Use shielded CAT5e industrial Ethernet cable for FTE network.
Usage Notes Redundant pair must use two identical CPCNT01 modules. Do not disconnect FTE cable during normal running. Static protection must be applied during module replacement. Backup control logic file before firmware upgrade. Do not use this module outside Experion PKS C300 system architecture.
