  • I am not getting the correct values...
    I had to check the Contiguous batches only and the analogs started working properly.
    The controller I'm talking to is a Siemens 353, in the opc server on other systems I have to set the max coil read to 32, or a low number, I can't find it in the newer manual I have...
    I have everything working in a KEPserver, and the only thing I have not gotten working in mango is the coils...
    any suggestions would be greatly appreciated.

    Thanks,

    Jim


  • I'll need a bit more technical info. Can you provide message traces and such? Also, you know that Mango's Modbus is 0-based?


  • Thanks for the quick reply!
    That was it...
    I had added all our analog tags first, and they all worked fine, so I didn't think about it..
    I do have another small issue though,
    Getting a lot of these...
    Exception from modbus master: Unrecognized Windows Sockets error: -1: socket available
    Now, I am running this on their server 2008 64 out there, I can run this on anything I want...
    Thanks,

    Jim


  • I've seen those errors too. I don't know how to get rid of them, but i also don't recall that they actually caused any problems. Are you seeing otherwise?


  • no, no problems at all.
    as we added more sites and more tags, the watch list update is a little slower sometimes, but that is to be expected.


  • How many points are you updating, and how often?


  • 6 controllers with about 20 tags each.
    2 local and 4 radio.
    will be adding about 4 more on the radios, and about 20 more tags to each.
    now polling every 30 sec, will probably change the radio sites to 1 min...


  • Hmm, that shouldn't be much load if the Mango host is a decent box. Can you quantify the watch list slowdown?


  • not yet, I was on my laptop with verizon wireless connection at a meeting the other night.
    A couple of them took about 5 to 10 seconds to update when switching between them.
    although we are also running a virtual box with the old wonderware polling the same points on the same computer...
    I'll know better next week.
    I'm on vacation right now...
