  1. We have a V570 that has been in use in the factory that suddenly jumped to the Info screen while in the middle of the program. The technician touched the screen calibration button and the target just keeps jumping around before it is even touched. We tried restarting the unit, but it does the same thing. Anything we should try or has this unit failed?
  2. Thanks for the method, but I'm not sure I'm all that interested in going to this length to get a plot. I was hoping to have an easier way to do it . I should also have mentioned that I'd be taking the x and y values from a data table (which your method would support of course).
  3. I was wondering if it is possible to plot an XY graph with the V570 where X and Y values are both based on analog inputs. I've taken a look at trends, etc, but it seems like they're all based on a time scale for the x axis. If it is possible, is there an example I can look at somewhere? Thanks!
  4. I'm looking at using a V570 with a V200-18-E3XB snap on I/O and am trying to determine the sampling time for the analog input. The documentation on the V200 states that the conversion time is synchronized to the cycle time. If I then look at the V570 documentation, it states that the cycle time is approximately 9usec/1K of program size. Am I correct in assuming that (1) the analog input will read a new value every scan and (2) if my program is 1K, the analog input updates every 9usec? If I am using multiple analog inputs, do each of them update every 9usec or do you have to allow 9us for each analog input? Or am I going about this completely wrong?
  5. Would you be able to mention the specific examples you are referring to here? I was looking through the sample programs there and not really coming across anything regarding this (from my perspective).
