data logging

Hello. We have a laboratory with 20 furnaces, mainly for ceramic, controlled with 2404 controllers and connected to PC over 485 network. We vould like to observe temperatures and some other parameters over time and note them in the graph. We did this with OPC scope. with the last version of the I-tools it works just for limited time, and then give the mesage that we shhould contact local representative to obtain the full version of OPC scope.
Does this mean that the OPC lite have limited time to note the informations or we missed something.
And if yes is for our neads purchasing of the full OPC the right thing.

Thank you

Leopold

    Hello Leopold,
    Itools comes with a 30min demo of the OPC Scope option - If you contact your local Eurotherm, they will give you a cost to add the OPC Scope(trending) option.

    Order code: ITUPG/NONE/NOC/NOC/TREND/NOC/NOC

    Regards, Jon

  • Hello Leopold,
    just some technical additions besides the financial part.
    At one running session of OPC Scope you can view up to sixteen different parameters, not more.
    ( The data logging can handle much more. I don't know if there is a limit, except of the Excel limits. )
    But you can run more than one session of OPC Scope at a time.
    For eaxample:
    20 furnaces with 2404
    every furnace: PV, wSP and wOP = 20 x 3 = 60 parameters
    4 sessions of OPC Scope. Session 1 - furnace 1...4
    2 - 5...8 and so on.
    You save these four standard screens ( group1.uix, group2.uix ... ) so you don't have to create it every time you start the PC.
    You will see that even twelve parameters at one screen are too many to watch.

    Hope that helps.

  • Hello

    Thank you for this answer. But actually I'm a bit confused now, but just a bit. We really have 20 furnaces, but normally we are observing 2 or 3 parameters from 1 or 2 furnaces at a time, but the time of one furnace run is from 1 to 10 hours.
    So please advice me, is the OPC appropriate for us ??

    And if I already have you on. Now we have RS458 network and conversion to USB. what mean also dedicated PC. I was thinking on use of RS485 to Ethernet converter. Is this also possible. And how we can then access to parameters (program changing, data logging), and what software we would nead. We would be interesting that each research ingeneer can access to his temporary dedicated furnace from his computer, without nead of checking the laboratory every 10 minutes.

    Thank you in advance

    Leopold

  • Leopold,
    the OPC Scope ( Trend ) is the cheapest way to have a kind of visualization to Eurotherm controllers. The "Trend" version is the one without any limitation of time.
    The way you described your needs an Ethernet converter will be the best solution to communicate from different PC's ( research engineer ) to one or more furnaces at the laboratory.
    Once you have integrated the Ethernet converter to your Ethernet you can communicate to the different 2404 with iTools ( change any parameter ) and/ or the OPC Scope ( data logging ) the usual way.
    Where are you located?
    Your local Eurotherm will help you to get the best solution.

  • Hi Leopold,
    you do not need any connection to the internet.
    You need to open iTools at the control panel and then enter the code you got.
