System compatibilityAM-C986-004 belongs to MODICON 984 series coprocessor module. Compatible with MODICON 984 series CPU backplane and related I/O modules. It works together with main CPU to undertake high-speed calculation and data processing tasks, supporting RS232C / RS422 serial communication. Suitable for legacy industrial production line, metallurgy and chemical control system upgrade and replacement as industrial spare part.

FunctionAM-C986-004 is high-speed coprocessor board for MODICON 984 PLC rack. It offloads complex mathematical operation, motion calculation and mass data processing from main CPU, improves overall PLC scan speed. It carries 256KB SRAM memory for data buffer and program operation, supports data exchange with main processor and external serial devices. Widely used for complex process control, serving as reliable expansion spare part.

InstallationCut off rack power before installation. Insert the AM-C986-004 coprocessor module into designated slot of MODICON backplane and lock the board. Check backplane bus contact. Configure coprocessor parameters via programming software and complete online communication test before formal operation.
