Hello,
I'm programming challenged and like the easy Rockwell Automation world, just not the price. So Unitronics has nice powerful solutions, but the software seems to lag behind a bit... So... what I'd like to be able to do in the Unistream platform is over-write the "read only" register "current count" from the UID-0808THS module. I have shaft encoders and prefer to work on the positive side of the number line. Negative roll over is a programming headache for me.
The application is a mechanical jack screw with 60 PPR A quad B encoder, signal feedback and wiring is easy and works fine. In my control code I take the raw data and scale to engineering units to yield a linear position feedback (jackscrew moving the load a specified distance).
In the Rockwell world, I can turn the counter off, reset to zero or some "preset" value that is meaningful to the application. What's nice about that is the programming is far easier and I can prevent roll-over problems by offsetting the number line using the preset value = non-zero value + a safety margin in counts (could be 10 x the feedback counts per rev.)
Does anyone reading this have has an application similar to this written in Unistream / Unilogic platform? I have my program attached if you are curious about the hardware and software setup. Version 1.7 rev 62.
If not, then I ask the capable guru's at Unitronics to consider enhancements to high speed counter firmware.
Thanks,
Greg
