3）Configure the communication protocol

4）Configure the communication protocol

Micro850_FreeTag Ethernet

This example introduces the establishment of Ethernet communication between Wecon V-box and CompactLogix L1769. It is introduced through three parts: PLC software configuration, V-box software configuration, and hardware wiring.

Software configuration of PLC

1）PLC programming software

2）New PLC project

Click New Project and select the PLC model.

3）Set Ethernet parameters

Follow the steps below to configure Ethernet parameters

PLC IP address：192.168.40.101

default gateway：192.168.40.1

subnet mask：255.255.255.0

V-box software configuration

1）V-box programming software

2）Configure device network

Click the Configuration Download button , It is used to configure the device network, update the device time, obtain the device machine code, check the device network, etc.

In the example below, the IP address of V-Box is configured as 192.168.40.66, and the networking method is 4G connection

3）V-net add device

Open VNET client software → add device. As shown in the figure below, click "+" in the order of steps, and the Add Device window will pop up, enter the device machine code/product code, device password, and device alias to add the device.

4）Set communication port parameters

In the device list on the left, find the Vbox that communicates with the L1769, click it and select configuration,communication port configuration in the main interface to add a communication protocol.

The communication port is selected as Ethernet, the device type is selected as Allen-Bradley, the protocol is Allen-BradleyMicro850_FreeTag EthemetIP, and the IP is the internal IP address of the L1769 PLC. The port number is 44818.

After adding the protocol Allen-BradleyMicro850_FreeTag, click icon add label.

5）Engineering production

According to your own needs, use the V-NET client software to edit the required data monitoring points.

hardware connection

1）Hardware wiring diagram

This example introduces Wecon V-box with Allen-Bradley L1769 PLC to establish communication through Ethernet. The connection diagram is as follows:

The above are all the steps for establishing Ethernet communication between Wecon V-box with CompactLogix L1769 PLC.

Micro850_FreeTag Ethernet（new）

This example introduces the establishment of Ethernet communication between Wecon V-box and 2080-LC50-48QWB,Micro850. It is introduced through three parts: PLC software configuration, V-box software configuration.
