Title: PID Structure Field addressing
Post by: HABCO on August 28, 2014, 05:23:54 PM

Can I address PID structure fields directly or do I need to move date into and out of them first?  For example I need to send a setpoint from a RedLion G3 HMI but the Do-More driver it has doesn't drill down that far in memory types. So what I have been doing is sending the SP to R0 and the moving it into .SP

I thought I had a light bulb moment when I thought to import the tag database into the RedLion but the PID fields don't seem to export from Do-More.

Everything is publicly accessible, the limitations are in the driver, so I don't have an immediate answer. You might try creating a nickname for YourPID.SP and exporting that.

I don't think Red Lion implemented internal structures, IIRC.  You'll need to move it in and out.

Thanks Everyone!

I was hoping I just missed something but I guess that's not the case.  I guess I'll be doing some moving then...
