DDMC2PF2 user manual is the user manual of Profibus-dp to MODBUS RTU/ASCII protocol conversion module released by JIETON Technology Co., Ltd. The main purpose is to exchange data between Profibus field bus and Modbus devices. It adopts Profibus dedicated chip and supports all Profibus-dp field bus systems.
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.
