Modbus TCP Server

[ibrahim eren]

Hello Mikhail,

When I try using it as a TCP Client, it works. However, my field modems do not operate as TCP Servers, so it is essential for SCADA to function as a Server. It claims to be listening on the port, but when I check via a port checker, it is not actually listening.

Thank you.

According to the log, TCP server is waiting for incoming connections, but no client is trying to connect.
Is Rapid SCADA installed on a cloud server or in the local network?
