Connection Parameters Needed for HMI/cMT Products to Communicate with a Mitsubishi QJ71E71 (Ethernet) using EBPro (EasyBuilder Pro)

PLC Setting

QJ71E71-100 Ethernet module settings:

1. Open Network Parameters in GX Developer

   Use USB or RS232 of Q-CPU for setting PLC parameters. Open Network parameters under the Parameter node in the project tree.

   

2. Click Operational Settings

   In the Network parameter dialog, select Ethernet/CC IE/MELSECNET and configure the module: set Network type to Ethernet, assign Network No. and Station No., then click Operational settings.

   

   

3. Select Ethernet (V2.0) and Set IP Address

   In the Ethernet operations dialog, set Send frame setting to Ethernet(V2.0) for communicating with HMI. Set the IP address in DEC format (e.g., 192.168.10.105).

   

4. Click Open Settings

   Back in the network parameter panel, click Open settings to configure TCP/UDP port parameters.

   

Configure GX Developer Connection

1. Press END to Finish Settings

   Press END to complete the Open settings and finalize the Ethernet module configuration.

   

2. Restart PLC Software and Read from PLC

   Restart PLC software and select READ FROM PLC, then select QCPU(Qmode) and press OK.

   

3. Set Network No. and Station No. in PC Side I/F

   In PC side I/F Ethernet board setting, set Network No. and Station No. Station No. 1 is the PC Station No., not the Ethernet module Station No. (range 2–64). The Network No. cannot be the same as that of the PC.

   

4. Set QJ71E71 IP Address in PLC Side I/F

   Select Ethernet module in PLC Side I/F to set the QJ71E71 IP address. The IP address must match the Network Parameter IP address (e.g., 192.168.10.105).

   

5. Configure Other Station Settings

   For Other station, click Other station (Single network) to set Check at communication time and Retry times.

   

6. Run Connection Test

   After finishing the settings above, click Connection test to test the communication and send the PLC program.
