PLCnext Engineer to Linux data transfer

PLCnext Technology & PLCnext Controls

Hello, So I am try to make a project that uses both the Linux side and the PLC of the AXC F 2152. Ideally we want to have a website running on the Linux side that will be able to directly send data to the PLC side (in PLCnext Engineer). The PLC side will then control the mechanical/electronic components. Nothing too complex, just simple integers. I’ve done a lot of searching to see whether this is a capability and we have been told that it is. We suspect it has something to do with accessing variable databases, but we’re new to programming PLCnexts. How do you have the Linux and PLC sides communicate data? Kind regards, Sean

Hello Sean,

there are some posibilities to communicate with the PLCnext runtime.

  • You can use the REST interface.
  • You could use PN or OPC UA
  • Remote Java SDK
  • “Sample Runtime” / AnsiC Interface
  • Setup some proprietary socket connection to your Server.
  • …

Have a look at the info center for more information. Have a look at the posibilities of the eHMI and how to attach HTML/JS etc. support files.
Maybe this will solve what you want to do already?
kind regards,
Oliver
