I have been using the 8055 to count the number of strokes our production machine makes in a minute. The code is in VB6. If we go below a certain number, the screen turns red and the chart goes below the target.
Weirdly, sometimes the counter shows that the counter has a counted an impossible rate. I cannot determine what it is, but I’d guess from the pattern on the chart that the count for that minute, typically 90 strokes per minute, is above 2000 for that minute. Any idea on what would cause the counter to mis read? Are there any fixes, like changing counter settings?
Thanks
Dave
There are no other settings available than this function:
SetCounterDebounceTime(CounterNr, DebounceTime)
It sets the debounce time to the pulse counters.
How often this problem occurs?
Do you reset the counter every minute after the read?
There are two counters. Does this problem occur with both counters?
Thank you for the quick response. I do reset the counter every minute. I will post the code later tonite.
Oddly, this only happens with one of the 5 installed Counter PCs Additionally, it started after the hardware has been working for about 1 year. I replaced the 8055 board with a new one. Perhaps it is the upstream allen bradley sensor, but I might be able to correct the problem with a “if counter is greater than 1000, then reset it, and use 100 as a count”
Thank you very much for your help on this. I am encouraged that we will solve this probem.
