LINGKONG GUIDE:As the middle bridge module switch module, a Profibus protocol into the RS232/485 protocol, the host information sent to FX2N from the station FX2N series PLC;Profibus, on the other hand the RS232/485 protocol into the Profibus protocol FX2N series PLC;Profibus, the FX2N from the station information is uploaded to the main station, to ensure that the FX2N exchange data through the PROFIBUS-DP bus and the main station.

As the middle bridge module switch module, a Profibus protocol into the RS232/485 protocol, the host information sent to FX2N from the station, on the other hand the RS232/485 protocol into the Profibus protocol, the FX2N from the station information is uploaded to the main station, to ensure that the FX2N exchange data through the PROFIBUS-DP bus and the main station.

Specific methods can be implemented using the following three:
1, directly connected to the FX2N programming, using MITSUBISHI's built-in FX2N programming port protocol, this method does not require any setting and programming in FX2N, only in the Profibus master protocol programming and so continue to read and write data can be FX2N from the station, from the station will master response response data.
2, through the FX2N communication module (FX2N232BD/ FX2N485BD or FX0N232ADP/ FX0N485ADP), using a MITSUBISHI protocol format or protocol format (four specific agreements are detailed in the MITSUBISHI FX communication user manual), in addition to the read and write data to and from the station protocol programming in the Profibus main station, FX2N station from the need of basic communication format set, but do not need to write the communication response program, FX2N will automatically respond to.
3, through the FX2N communication module (FX2N232BD/ FX2N485BD or FX0N232ADP/ FX0N485ADP), write your own communication protocol, this method not only need to master in the Profibus protocol programming according to continuously read and write from the station data, also need to FX2N from the station to write communication program master call response time. Although this method is cumbersome, it is flexible and adaptable. In fact, this method not only can be used in the FX2N series PLC, can also be used in other PLC or intelligent instrument, as long as the two sides set a consistent agreement, are available through this method, CZP1-PQ20-T10ZL2-1A Profibus universal RS232/RS485 bridge module TrumpJet company, to achieve the equipment on the function of the Profibus network.
