Isakovic Posted September 1, 2016 Report Share Posted September 1, 2016 Hi, I opened U90 help files by mistake instead of Vision help files , and found that for HSC it says "Counter value is an integer with a range of -32768 to +32767. After the counter reaches the maximum value of +32767 it will continue to count in the negative range. " I couldn't find similar statement in VisiLogic help files. Now, I plan to use Vision controler V430, and in Technical Specifications for V430-J-TR34 it says that hardware counter has resolution of 32-bit. Does that mean that I can link ML to high speed inputs and they will count to 2^31? I am using two shaft encoders if it's of any matter. I wasn't even thinking about this question, but since accidentally I looked at U90 help it's been bugging me. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted September 7, 2016 MVP 2023 Report Share Posted September 7, 2016 Don't let it bug you. Visions are way more powerful than M90s. You can assign an ML to an HSC input with no problem. Here's the catch - it will reset to 0 when you cycle power. I put an STO block in that continually copies the ML value to another ML with a NC of SB2 in front of it. This creates a running buffer of the value. I use an NO of SB2 to copy the buffer back to the HSC accumulator so I don't loose my place on power-up. Joe T. 2 Quote Link to comment Share on other sites More sharing options...
Isakovic Posted September 8, 2016 Author Report Share Posted September 8, 2016 Thanks for the response. Machine operator will need to run home routine upon turning on so I won't be needing position backup. Quote Link to comment Share on other sites More sharing options...
