Ethernet TCP\IP: PC to Vision

TCP/IP Project Settings enable VisiLogic to access a Vision PLC via an Ethernet connection. Each PLC included in the project will be accessed according to the protocol and port number assigned to it.

TCP/IP Project Settings contain IP addresses and settings that are specific to a particular VisiLogic project. However, you can add any of the IP addresses it contains to the Favorites file, which is a common, global file that can be accessed from any VisiLogic project.

1. Select TCP/IP Settings from the Project menu.
    

   

2. Open the IP Address Selector in order to enter the IP of the PLC s in the project.

 

 

3. Enter an IP address either by:
   - Typing it,
   - Importing any IP addresses you may have defined in your project within TCP/IP Init FBs
   - Importing the IP of a PLC currently linked to your PC via a valid communication connection.

 

 

Note ♦

If you import a Vision's IP, its protocol type (UDP or TCP) and port number are also imported. If you have typed the IP address, you must also type the port number.

4. Before exiting TCP/IP Project Settings, you must set the PLC name. This is a unique name that is assigned to the controller via the Set PLC Name FB.
    

Note ♦

You can add any PLC defined in TCP/IP Project Settings to the Ethernet Favorites file.

Favorites is a common, global file that can be accessed from any VisiLogic project, as well as by other programs such as Remote Access.

Favorites is a file that is created by VisiLogic after you have added a PLC to the favorites list. It is a global file stored in the Program\Common files\Unitronics folder as Eth_Favorites.evb.

Ethernet Favorites is located on the Connection menu.

Once Favorites have been created, you can access them in order to:

• Import the definitions into TCP/IP Project Settings.

• Select a PLC listed in Favorites to enable VisiLogic to access a PLC via Vision Communication - PC Settings.

Once the conditions above have been met, VisiLogic can access a selected PLC via Ethernet.

1. Select Communication and OS from the Connection menu.

2. Under Connection Type, select TCP/IP (Call), and then select the target PLC from either Project Settings or Favorites.
   

VisiLogic is now ready to communicate via Ethernet.
