Upgrade from 4.6.2.2 to 4.7.1.5 bouncing timers

For some reason when I am trying to upgrade from Pro Suite 4.6.2.2 to the newer Pro Suite 4.7.2.4 (or 4.7.1.5 or 4.7.0.47), a couple of my timers start bouncing their values. These are standard TMR timers. Using hour units. And the value bounces up and down several 100 "hours" every second. No idea what to try in order to fix this. Delete the rung and make a new one? Can I trust that the other couple dozen or so timers in my ladder are not also randomly corrupted? Adding an always off contact at the enable seems to stablilize it. The enable signal does not trigger a counter.

 

Older P2-550 on a P2-07B. Was on older firmware but have upgraded to 1.3.0.6 and 1.0.16.0.

LMK and kewakl like this.

    Or development team discovered a bug that was introduced in Productivity Suite v4.7 that is affecting the Reset pin of the timer instruction and causing the issue that you are seeing. The bug fix will be in the next release of the software. In the meantime, the only work arounds are to either fall back to Productivity Suite v4.6 or disable the Reset pin of every timer and add code to reset the current timer value to the reset value.

    We sincerely apologize for the inconvenience this has caused you.

    Can you post an example? Are you allowed to post a project?

      • kewakl (Customer)

        Understood.

        Posting a project would be: zipping the <your project>.ADPRO file and posting that .ZIP archive to this forum.

        So I should probably delete email addresses out of the ladder. Are IP addresses also included in the project for things like the HMI and my remote devices? Any way to click a button and it anonymizes it?

        When possible, I try to build a MRE

        I understand that not all issues have a small reproducible example.

    Could you connect to the CPU online, generate a system report using the older v4.6.2.2 software, then repeat the process with the newer v4.7.2.4 project, and PM both reports to me? Then we can attempt to duplicate here on our end. Thanks!

      I do have a ticket open where I sent those system reports. 02669241. Also working on sending Wayne some videos of the bouncing tag values. But they are big.

      • RedBarn (Customer)

        Changing names of tags and making new timer does not fix it. Too many timers?

        If you have access, HandBrake can trim/transcode to other formats for size

    @RedBarn (Customer)​ Which task and rungs of the timers is having the issue? I am running your project in 4.7.2.4 Heat pump control task and not seeing any huge swings or jumps on current values.
