In GX-Configurator DP start a new project and select the QJ71PB92V.

The master settings can be left as default for easier setup, however these can be changed if necessary, in this case theBaud rate is 1.5Mbps, FDL Address is 0 and Start I/O Address is 0000.

Click next.





Version: 1



In this window, the head addresses for buffering I/O and diagnostics are set. For easier setup these have been left asthe default settings of Block transfer with Input data starting at D1000 and Output data starting at D2000. The

diagnostic data areas have not been set in this case. It is important that the Consistency box is checked. Other settings

have been left at their default setting.

Program written in ladder for Master.

In GX developer, set the following program for the QJ71PB92V.

This program check the status of the module and initialises the data exchange, the program also transfers data between

the user areas and the buffer areas.

The I/O signal for the QJ71PB92V are bases on the module being in head address 0, on this basis the following table

shows all I/0 with details for the module relative to this position.

Inputs and Outputs for the QJ71PB92V

For more details on the QJ71PB92V please refer to the user’s manual ref: QJ71PB92V PROFIBUS/DP MASTER, Art. No.166558, SH(NA)-080572, VERSION C.







Program for FX3U Written in ladder for slave 1.

Open a new FX3U project in GX-Developer and enter the following program for the slave station.







This program sets the station number of the slave, checks the consistency and data exchange status. The program also

writes data to the master and reads data from the master for 64 words each way. The method uses U/G instructions in

this case as they are supported in the FX3U.







Program for FX3G Written in ladder for slave 1.

Open a new FX3G project in GX-Developer and enter the following program for the slave station.







This program sets the station number of the slave, checks the consistency and data exchange status. The program also

writes data to the master and reads data from the master for 64 words each way. The method uses TO/FROM

instructions in this case as the U/G instructions are NOT supported in the FX3G.
