CMDC2PF2 is a protocol conversion module used for exchanging data between Profibus fieldbus and Modbus devices. It supports Profibus-dp fieldbus systems and features optional Modbus RTU/ASCII master/slave, support for multiple commands, and adjustable communication rates. The module is equipped with isolated communication circuits, lightning protection, and reverse power protection.
The CMDC2PF2 protocol conversion module enables data exchange between Profibus‑DP fieldbus and Modbus devices. It supports Profibus‑DP slave communication, Modbus RTU/ASCII master or slave modes, adaptive baud‑rate selection, isolated communication loops, and protective features such as lightning and reverse‑polarity protection.
The manual details hardware dimensions, power requirements, wiring, address setting via SET/SEL buttons or the JTconfig software, parameter configuration, and diagnostic functions. Installation can be performed on a standard U‑type rail, and the module provides LED indicators for power, communication status, and error conditions. This manual is written in Chinese.
