TCP or UDP communication

[IDP]

Hello ,

We want to use TCP or UDP communication between a dedicated print board and the ctrlX Core ( in a ctrlX drive plus ) .

Does this already work ?

Do we need a special app to do this ?

Do we just have to use the TCP or UDP libraries in the PLC programm ?

Is there somewhere a description of how to do this ?

Thank you .

Hi IDP,

this just works out of the box.

The PLC App has full access to all ethernet ports, just use the function blocks in the plc.

The library is "Application/ctrlX AUTOMATION/Communication/CXA_SocketComm"

Find attached a small PLC Project for UDP and for TCP

In general the ctrlX CORE can use any TCP/IP based communication protocol. Independet if drive integrated or not. There just needs to be a communication master/client available.

PLC Based:

• TCP, UDP, FTP, ...: CXA_SocketComm library (Rexroth)
  ctrlX PLC Engineering CXA_SocketComm
• HTTP: APP_HTTP library (made by application department) or HTTP Client library (3S)
  
  

ctrlX Node-RED app based:

ctrlX Node-RED network palette

 

Own App based:

Of course you could always create an own app (snap container) runnable on the ctrlX CORE to do such communication in the programming language of your choice.
