I've got an issue with resetting a counter to 0 on a Micrologix 1500 with a 1769-HSC card. The preset is configured in the IO configuration for 0 and I set the soft preset bit (in this case O:2/81) but nothing happens.
The reset works perfectly when I first download the program but if I upload then download again it stops working. The customer has also rung me after a couple of days to say it's stopped working all by itself. The last time it stopped working I downloaded the original copy of the program and it worked fine, but this time I need a more permanent solution.
I do have the reset on a one shot so the first thing I'm going to try is removing that and holding it on for a while but they'll soon get sick of pushing a button for 20 seconds waiting for it to reset.
I've found a couple of things on the knowledgebase. Article 42716 talks about issue when the other counter is enabled but I'm sure it's not enabled.
Article 56789 says to go into the Input Config screen, check the box for the Reset Counters. Then go to the Counter Configuration tab and verify the value in the Preset. I can't find a Reset Counters box anywhere so I'm thinking that might refer to the compactlogix version and the value in the preset is 0.
I'm going back to site tomorrow to try a few things but I was wondering if anybody on here had some ideas of things to look for.
Cheers!
