Good Day Support Team,
Few months ago i built an application running with ModBus communication. On the laptop i made it, it works like a charm.
Then i've installed VTScada on another laptop, and import the project that was on my persoanl laptop on this new one.
i set up the fixed IP address as suppose to be, but i have no communication at all. I can PING the IP of the PLC, so it means that the laptop can see the local network device, but there is no communication between the PLC and VTSCADA.
Where i am doing wrong ?
