UDP SOCKET

[Angeles]

This means that another script is already bound to this UDP port. You can find script PID like this:

Code:

res = io.readfile('netstat -puln | grep 8891')
log(res)

Or open print view for all scripts (Scripting > Tools > Print script listings) and search for 8891 there.

Hi again:

The system that I try to read is a energy meter concentrator. We manage to communicate with the device through the usr-vcom application and we receive data. The system was already installed when our clients hire us but anybody know how read the data and there is not any program.

We have test with protocol modbus, mbus and there is no response. The communication throught USR-TCP232-T2 -  (TTL - ETHERNET).

When a create a socket.tcp the connection is correct but receive is nil. What could be the problem.?

Thanks for your help
Best Regards.
