JTPLC DDMC2PF2 Protocol Conversion Module User Manual
The DDMC2PF2 protocol conversion module enables data exchange between Profibus‑DP fieldbus and Modbus devices. It supports Profibus‑DP slave communication and optional Modbus RTU/ASCII master or slave modes, with configurable baud rates and address settings.
The manual provides hardware installation on a standard U‑type rail, wiring diagrams, parameter configuration via dip switches or software, and fault‑diagnosis features. It also details how to map Modbus registers to Profibus remote input/output words for seamless integration with PLCs such as Siemens S7 series. This manual is written in Chinese.
