This practice is dedicated to all the readers of this website who have written to me asking for an entry dedicated to the SCADA Factory Talk View.
The first one I am going to make will be the communication between the SCADA and the PLC.
The PLC I will use will be the RSLogix Emulate 5000 simulator, and here you can find how to configure it. What will also be needed is the configuration of a Topic in RSLinx, and here is how to configure it. Once those preliminary steps are completed, you can proceed with the steps described below.
Once we have created our project in Factory Talk View, the first thing we will do is add the link to our PLC, and we will communicate through the RSLinx OPC Server. By right-clicking on our project, we add a new OPC Data Server.
A configuration window appears where we give it a name of our choice and select the OPC Server as can be seen.
Once added, it can now be seen in our project; this refers to the RSLogix Emulate 5000, and we can access the tags we have in our project since the created topic points to it.
To verify that the link is created correctly and its functionality, we will insert several numeric display type objects to visualize some variable from our PLC.
In the properties of the numeric Display object, we click on Tags to configure the variable we are interested in visualizing.
When clicking on Tags, the Tag Browser opens, where initially the tags do not appear, so we can take one of several options, but in the case of having multiple links, the ideal would be to show the Servers and the tags belonging to each of them.
Once we have configured a variable and a button with the Toggle function, to perform the data reading, we can start checking the steps taken by clicking on the icon that plays or observing the results.
