I am new to using CXA_SocketComm TCP.
I manage to established connection from ctrlX to a TCP device. However i did not receive feedback from the device after sending a string. (see attached)
Looking for advice.
Solved! Go to Solution.
I created some examples for communication via TCP between ctrlX CORE and ctrlX COREvirtual. See "Communicate between a ctrlX COREvirtual and other applications [DOCU]". There I am using Node-RED but PLC works in a similar way.
Which function blocks exactly are you using in your example? Normally you have a TCP server on one side permanently running and a client connected to it waiting for getting data.
I am using IL_TCPConnectionAsync function block library.
Thank you for your tip we tried setting up TCP communication in Node-red, connection is established however when we attempt to send a string it did not send to the device and no feedback from the device.
We solved it by using Telnet communication in Node-red. It is unsure why it is behaving this way.
Good morning, not if this is what you are commenting on. I pass you a document on communications in general and another on communication between XM and ctrlX Core in NodeRed using the IL_TCPCyclic module
