Mitsubishi FX2N series PLC and Profibus link

The bridge module is used as the intermediate transfer FX2N PLC and Profibus Mitsubishi module. FX2N PLC and Profibus Mitsubishi On the one hand, the Profibus protocol is transformed into RS232/485 protocol, which makes the FX2N from the station, on the other hand, the RS232/485 protocol is transformed into Profibus protocol, so that the FX2N from the station to the main station to ensure that the FX2N through the PROFIBUS-DP bus and master data exchange.

Implementation uses the following three <a href="/searchfanan.html?search=type&select=7">types:

1, directly connected to the FX2N programming interface, the use of MITSUBISHI's FX2N programming interface protocol, this method does not need to make any setup and programming on the Profibus, just in the FX2N master station and so on.

2, FX2N (FX0N485ADP FX0N232ADP/), (FX2N485BD FX2N232BD/), the use of MITSUBISHI protocol format four (specific protocol content in the MITSUBISHI FX communication user manual, in addition to the need for this protocol programming on the Profibus master station data, the FX2N from the station need to set up the basic communication format, but do not need to write a communication response program, FX2N will automatically respond.

3, through the FX2N communication module (FX2N485BD FX2N232BD/ or FX0N485ADP FX0N232ADP/), write their own communication protocol, the method is required in the Profibus master station in accordance with the protocol programming to read and write from the station data, but also in the FX2N from the station to write a communication program to respond to the call. Although the method is more troublesome, the protocol is flexible and adaptable. In fact the method not only can be used in FX2N series PLC and application in other PLC or smart meter, as long as the agreement on both sides of the set a consistent, all, this method can be used, by a Czech company PROFIBUS universal RS232 / RS485 bridge module CZP1-PQ20-T10ZL2-1A. To realize the equipment connected to PROFIBUS network function.
