Title: Text string into a math block?
Post by: Garyhlucas on June 03, 2024, 01:20:03 PM

I was wondering if you could input an equation as text in an HMI and then send that into a BRX math block to do the calculation. We have an application where this would be useful.

No, sorry. All math is precompiled by DmD. To do what you are describing would require the PLC to be the compiler.

Thanks,
I think we can probably build an HMI screen with fields to do the job, but this seemed like it could be pretty slick.
