Read SPEED OVERRIDE setting from LR Mate over TCP / OPC / somehow?

  • I would like to know if our robots have speed reduced using SPEED OVERRIDE.

    I have Ethernet connection, FTP, etc.

    I have Inductive Automation's Ignition SCADA with TCP driver, Modbus RTU, and Modbus RTU over TCP.

    Can anyone give me a clue how to get started - if it's possible at all?

    Many thanks.

    Approved the thread.
  • What are you trying to accomplish?

    There are ways to read the current speed, but there are other ways to force the robot to run at whatever speed you want at all times, or to force the speed to 100% at start up, and then allow the user to control the speed.

    Check out the Fanuc position converter I wrote here! Now open source!

    Check out my example Fanuc Ethernet/IP Explicit Messaging program here!

  • Thank you for the reply.

    Our robot programs have `OVERRIDE = 100%` in the program but technicians slow them down sometimes to solve (floppy) product placement issues. We'd just like to track that and see what's going on. If they're having to do it frequently it would tell us that we need to improve the program.

  • I think you are looking for something like this. This person on github did a project that is licensed MIT. His code matches his SNPX_ASG instead of being portable, but that shouldn't matter for DI/DO. Specifically, the decode_bit function in is what you would want to call to monitor the DO. You do need the HMI option for this.
