The detailed user manual for YASKAWA MEMOCON-SC 2000 series reversible counter module B2801 (model JAMSC-B2801) covers installation environment requirements, 4 types of counter functions (compare/cycle/sample/store), I/O interface configuration between CPU module and external devices, terminal wiring specifications, fault diagnosis and testing operation process. It supports GL20 (6-digit counting) and GL60S (8-bit counting) CPU modules, with a maximum counting speed of 200kpps, suitable for industrial pulse counting and signal output control scenarios, emphasizing safe operation and anti-interference wiring requirements.
Scanning time error (1016 relay ON): CPU scanning time is too short. Add ladder program or virtual allocation; Extend scanning cycle
3. Troubleshooting process
Observe indicator lights: RDY (module status), ERR (error type), ENB/INC/DEC (counting status)
Read input relays: READY, Preset NAK, Scanning time error
Check the setting parameters: Read the initial setting value through the input register, confirm that the function mode, magnification, and preset value are correct
Check hardware connections: loose terminals, damaged cables, grounded shielding layer, power supply voltage
