Mitsubishi Q series PLC and GX Works2 connection method

01 USB connection

USB connection requires the device USB driver, generally the device will be actively driven after the installation of GX Works2 software, but at a single time due to anti-virus software or system reasons, or the device may not be available, then we need to manually drive the device to the accounting machine. You can find out the specific device method by yourself.

The USB interfaces of different CPUs are also different, some are square USB, the scientific name is TYPE-B, and there is a trapezoidal USB port, the scientific name is Mini-B, which is a little smaller than the square port;

If you use USB connection, you can directly set it to USB connection, and you don't need to select the COM port like FX3U, just select USB directly.

02 The CPU comes with an Ethernet port connection

First of all, use the CPU's built-in Ethernet port to connect, and select the three options of computer side-programmable controller side-other stations in turn;

Among them, the accounting side refers to the connection method of our computer, and the selection of Ethernet Board generally refers to the network card of the accounting machine;

On the programmable controller side, select PLC Module, which refers to the CPU component body.

Other selection, select No Specification, which refers to accessing this site, that is, the CPU itself;

Then, double-click the PLC Module button again to enter the PLC side setting;

There are two situations here, one is that the computer is directly plugged into the network cable to the CPU, which does not need to set the IP address to be connected;

The other is through the hub, that is, the switch for connection, here you need to set the IP address, to be common with the IP of the built-in Ethernet port of the CPU, here you can find through the built-in Ethernet PLC on the search network, the IP address will be displayed;

Ethernet IP to PLC parameters;

03Communication via Ethernet module

Mitsubishi's Ethernet modules communicate with third-party Ethernet devices, and through switches, they can communicate with many devices, and of course with GX Works2.

First of all, set up the Ethernet module, here added three Ethernet modules, separate from different communications, some are dedicated Ethernet modules, such as MES communication, and video communication, and some Ethernet modules are universal, mainly used to communicate with touch screen, computer debugging, here the third network card is with the touch screen and debugging communication, pay attention to the network number is 1, station number is 1;

Click Run Settings, set the IP of the Ethernet module, and click Set to complete when the setting is finished;

If you want the computer to communicate through GX Works2, you want to add MELSOFT connection, only one computer is allowed to connect to one channel, if you want to allow multiple people to debug the connection at the same time, then set up a few more channels;

After the parameters are saved, they are downloaded to the PLC through USB connection or built-in Ethernet module connection, and then the Ethernet connection method can be used.

QJ71E71 create a new connection method, double-click to enter

Click the connection method Ethernet Board on the computer side, and set the network number and station number, the network number is common to the Ethernet module, and the station number is not common to the Ethernet module.

On the PLC side, select the Ethernet Module, set the station number and IP address, and the station number here should be the same as the station number of the Ethernet module.

Click on the other two items to complete the setting;

Click on the communication test, and it is now connected to the PLC;

After setting the connection channel as the default, GX Works2 will use it as the default connection method to communicate with the PLC in the future.
