It is possible to reference a tag in a remote application (one running on another computer) inside of a local InTouch application on a different machine. To do so, you will first have to set up an access name to the WindowViewer session on the remote machine. The second part involves creating an I/O tag in the local application that references the tag you are trying to read in the remote application.
NOTE: WindowViewer must be running the application on the remote machine for the live value to update.
- In the local application set up a new access name following the example below.
Node Name: <Host Name / IP of remote machine>
Application Name: VIEW
Topic Name: tagname
- In the local application create a new I/O tag in the Tagname Dictionary that references the InTouch tag on the remote system/application.
Access Name: Access name you mapped to the remote InTouch application.
Item: Tag name of the tag in the remote InTouch application.
