I would like to set up a modbus communication using TCP/IP.
In order to test it, I wanted to set the communication between two Matlab sessions on the same computer and set up the communication using local IP address.
To do so, I tested the following:
m = modbus('tcpip', 'localhost');
m = modbus('tcpip', '127.0.0.1');
but in both case I get the following error:
Error using modbus (line 96)
Requested transport resource is either in use or does not exist. Unsuccessful open: Connection refused (Connection
Is it related to a configuration that I have not done on my computer or is it impossible to set up such a communication?
Thanks for your help.
