I've downloaded and installed VTScada 12.2.26. Once I got the training simulator application running. I wanted to start following along instructions from the Student Workbook: VTScada Operations & Configuration Course Guide on setting up the port and driver. It tells me to set the IP to 127.0.0.1 and the port to 501. Once I added a digital (pump running) I was expecting to see the values for the port and MCD tags showing a 0. It was instead showing a 770 error and a -10,061. I've installed VTScadaLight on my personal laptop using my home network. I read somewhere else that I would have to setup a server through thin client/server setup. I honestly do not know how to do so. The only luck I had with the tag browser showing a 0 value was by adding an authorization realm. I have had some luck in using OpenModSim as a modbus simulator to VTScada. I'm not entirely sure on how to properly use the app though, so still learning. What I'm wanting to do is try to set up an environment where I can learn VTScada more without using a licensed version of VTScada I use at work. I have also created an inbound rule that will open port 501. Is there any way to determine that the port is open to allow traffic ?
