COMPACT LOGIX firmware v36 - digital tags not working

Ryan Huynh

Hi,

Just updated our driver abclx to the newest version 5.6.0.2. 

Everything is working except our digital tags. Keep saying bad and saying [802 ] Structure not found : Alarm_var.Alarm_1.9. in syslog. 

Any opinion will be appreciated!

    What 's the driver version you upgraded from? Take a look at Readme_ABCLX.html and see what are changes between the previous and latest versions of the driver. Hope that you could find some helpful information.

    Hi Jacky,
    I upgraded from 5.03 . I don't see anything mentioned about digital tags. I've compared it to other existing ABCLX plc, syntax of my digital tags are same with others. Not sure why it is not working!

    Hi  

    If possible, I'd recommend rolling back to the previous ABCLX version.

    Please reach out to AVEVA Technical Support so this issue can be investigated further.

    Kind regards

    hi Oliver, 

    I didn’t mention other tags are working fine, did I? If you look at variables window, you would see total of 11 tags of this plc, they are all working fine except 2 digital tags. 

    If I roll back to 5.03, this plc won’t be connected as it compact logix firmware v36. 

    When I was at v5.03, I tried everything but it kept saying driver error. I actually found your reply and downloaded the v5.6 and got it connected.

    Hi  

    I'm a bit confused, what exactly has changed in your system? What PLC and driver version was working previously? What other changes, besides the ABCLX driver upgrade did you do on the system?

    It would be helpful to also specify the PLC details, exact model and firmware version you are running.

    The Driver team have confirmed that communications is working in their test system with Control Logix and digital tags. It is not possible for them to test all hardware combinations, but it should be possible to get communications working with Compact Logix PLCs from previous experience we have had with customers.

    Here is what they suggested you try:

    1. If digital tag is belongs to the structure which is having some elements with external access NONE? if yes, can you please ask customer to disable below INI parameter and check the behavior.
      [ABCLX]
      OptimizeUserDefinedDataType= 0

    2. Please ask customer to create a simple Plant SCADA project with less than 10 tags and try to reproduce the issue and capture the Wireshark logs and sys logs by enabling below INI parameters.
      [ABCLX]
      DebugLevel= ALL
      DebugCategory=ALL
      LogTagInfo=1

    I recommend doing the above and then contacting AVEVA Technical Support to get the logs analyzed.

    Kind regards

    Thanks Oliver. Issue came from the alarm_var.alarm_1.9 . It should be alarm_var.alarm_1/9.
