The JTPLC CMDF5-4AD User Manual provides installation, configuration, and operation instructions for the 4‑channel analog input module.
The CMDF5‑4AD is a 4‑channel, 12‑bit analog input module designed for Profibus‑DP fieldbus systems used with PLCs, DCS, PCS and computers. It supports multiple input ranges (0‑5 V, 0‑20 mA, 1‑5 V, 4‑20 mA), isolated power and communication, and offers LED display and button‑based address/parameter setting.
The manual covers hardware installation, power connection, Profibus‑DP wiring, GSD file installation in STEP 7, parameter configuration, troubleshooting LEDs, and sample STEP 7 programming for reading analog values. This manual is written in Chinese.
