In this practice, we will communicate Intouch with RSLogix Emulate 5000 through the FSGateway which in turn links to the RSLinx Configuration as OPC server.
It could be a real configuration if RSLogix Emulate 5000 is replaced with our PLC.
1.- We start our project in Intouch and add a new Access Name, Application Name is FSGateway and the topic is the one configured in the practice FSGateway
2.- Once the Access Name is created, we will add the items (variables), select their corresponding Access Name and we will use the tag name as the item (variable) name
3.- We will use the names we gave when configuring the Items in the FSGateway configuration, as shown in the following image.
4.- Now we configure all our screens, in this example we will visualize the values of the variables and some buttons
5.- We can now run our Runtime and observe the results, we use the simulator to force the inputs, it can also be checked how RSLinx is active and the items it is serving.
6.- At the same time, we can also check how our FSGateway is functioning correctly and the items it has configured
7.- In the following image, I have added some LEDs for better visualization and a button with the Toggle function, but if I execute the input with the button, although in the SCADA it shows that the input is activated, it is not so. If you observe the simulator and the online program, you can see that the value is not forced, ideally, the simulator should be used to force the inputs
On the other hand, using the Simulator everything seems more real when working simultaneously with RSLogix for our PLC program and our SCADA
