So you are saying that the default Vision conversion from Frequency Measurement to MI just happens to be 600 ppm (or 2400 with X4)? If I had used any other ppr encoder I would have to do some math, but 600 ppm is correct.

Well Kratmel, thank you for the reply, but I'm not following what you are saying... I am doing no calculations, but yet my assigned MI for frequency measurement (here MI 17) is giving me a number that closely matches the speed (rpm) displayed by an existing speed display. Hence my confusion, as like I said, nowhere in the encoder config. or code do I specify the ppr of the encoder, but yet it is correct...

Hey All, I've been playing around with an encoder connected to a V200-18-E3XB. This is a 600 ppr A-B encoder, configured in X4 mode (which I believe gives me a 2400 ppr count as it counts the rise/fall of both channels, correct me please if this is wrong).. I have assigned MI 17 for the frequency measurement of said encoder. The number I see in MI 17 matches the speed of the shaft I am connected to. All Good... But Why? No where in my code have I specified 600 ppr (X4 2400 ppr), and I assumed somewhere I would have to scale/linear MI 17 into a number that matches my real speed. What am I missing? How can it be correct if I have not declared the actual ppr of the encoder somewhere in my code??? Assigning the Frequency Measurement option gives the choice of 100ms,500ms, or 1000ms, does this come into play? I just assumed that was the update time.. JohnR

So, Joe, Are you saying that after version 9.9.0 that it is now required to enter an INFO password, rather than the default "1111" that has been there for years? Like others I'm noticing a lot of questions regarding this on the forum, and it has me puzzled. I'm still using 9.8.65 (as we always say, "don't upgrade just because you can"), but it has me curious, this seems to be a change that is catching folks off guard. Is this a topic that needs to be "pinned"?

V560 with a V200-18-E3XB snap IO, or alternately an external IO-A18 module... JohnR

Hey all, Simple question about vision analog inputs (I hope).. what happens if I feed a negative voltage into a 0-10V analog input? does the associated MI go negative or does it just stop at zero? really didn't see anything about this in the help files. figured I'd ask before chance damage to my hardware.. JohnR

I had this problem once, and Joe T provided me with this answer. You have to tell Remote Access to upload the PLC's images and create a local use file-

MarvinP; Seems to me you are making assumptions about the PLC programming environment, this is not some structured thing that you can treat like some Excel/Access/Powerpoint program. It entails understanding control logic, which is something you have to embellish from a real hands on type of structure, not spreadsheets and databases... yyh2, sorry, but no, this is not some top secret subject, but it is something you have to learn and understand. Nobody can wave a magic wand over your head and give you all knowing knowledge. You have to try (and yes fail from time to time), but if you first try (and that is the prerequisite), then ask questions, folks on this forum will gladly help you. But, sorry Charlie, nobody is gonna hand you a Golden Ticket...

These cables are included with the PLC when you buy a new one (not some $100 cable you have to buy separately like some other manufactures). And any Unitronics supplier is likely to have some on hand. I have a half dozen new in package, would be happy to send you one for the cost of shipping, PM me if you are interested. JohnR

I think that establishing solid communication is only one part of the puzzle. Completing the update is another puzzle piece. And then you will find out whether or not you actually have a valid application to run.

And I've found over the years, that coworkers with a "Goey-In" can be much more rude & crude than us with the "Pointy-Outs".. Just sayin"...

this may sound silly, but what happens if you put your setpoint at 552? does it settle in at closer to 550, or stay at 548.8? numbers are just visual indications of what's going on, but sometimes you just gotta tweak the numbers to get/show the results you want.. Just my 2-cents

Well, that movie came out in the late 70's, I was in my early 20's... So you were about 6? 😇

Well if no one sees it but me, I guess I should just ignore it.😌 Yep, that's where the saying came from. good memory..

Naw, actually been there since early summer, just took me that long to ask questions about it.. Hmmm, maybe around the time of elevator discussions?
