Have someone noticed that the data chaged event for data subscribers triggers twice or sometimes more?
I use AHMI v3.6.2 in a project we started but was put on hold months ago. Updating to "after v3.8.0" version it will be unlikely as we only use a simple tags monitoring. We connect to two Compact Logix and monitor only a couple of string tags in each of them. One of those tags holds a number and on the change event I analize its value with a case function. What I see when debugging, is that the event starts and finishes normally, then starts over without having to change the value contained in the data subscriber, executing the same code again. No problem so far, as my code will not have a negative effect from that, but I do not like the idea when I use something that has to be executed just once.
I'm on VB.net 2013, pro edition.
