Talking to...a Raspberry Pi?

And now for something completely different!! (-;…

One of our very clever staffers developed a QC project that runs on Raspberry. If you’re not familiar with it… give a Google. Neat little computer-on-a-board. I use one to interface some home automation equipment but never really considered industry possibilities.

…and this guy is using it in place of Labview! Really clever!

Anyhow, he’s getting some data from it that we’d like to get into Ignition. Anyone got ideas? FTP, OPC on Raspberry…heck, I don’t know. I suspect he’s running a Linux flavor OS on it, so a lot may be possible. I’d like to dig in a little further and would appreciate hearing others ideas or experiences!



Can he have the Raspberry Pi write to MYSQL database (or other DB) on the server?

Once there then Ignition can get the data from the DB.

Today, I just got one of my Pi2’s loaded up with CODESYS and simultaneously running an Ignition client. CODESYS has OPC-UA builtin, and for 35 euro + VAT (came to a little less than 50 USD, all told), it’s not a bad deal.
Other functionality:

  • CODESYS EtherCAT Master
  • CODESYS Profinet Master
  • CODESYS Modbus TCP Master / Slave
  • CODESYS Modbus RTU Master / Slave (serial interface must be supported by and installed in the OS)
  • CODESYS WebVisu
  • CODESYS SoftMotion CNC
  • CANopen via EL6751 Gateway
  • CODESYS EtherNet/IP Scanner
  • CODESYS EtherNet/IP Adapter

Now to finish up an interface board design for the GPIO…
