  1. Dear All,

    I am having a problem with my cimplicity Auto Report Generation, When I Click on Generate Report,

    it shows "0 values collected" does anyone knows what's possibly could gone wrong here ??IMG_20180809_131726.thumb.jpg.b75016274d

    kW x hours = kWh

    If power consumption is constant then it's easy. Run time in hours x kW usage = kWh.

    If it's not constant (more likely) then it becomes more interesting. Not difficult, just more interesting.

    Personally, I would make it an AOI so I could use it for individual users (motors, etc) or total power, variable load, etc. I would use a periodic task. I like structured text for things like this.

    Kind of like so:

    GSV(task, THIS, Taskrate);  // Get the rate of the periodic task. Units are microseconds

    t := Taskrate / 1000000; // Convert task rate in microseconds to seconds 

    kWh := kW x t; // calculate kw(t) where t is the number of seconds of the period. If t is 1s then the units are kWs. If t = 60s then kWm (kilowatt-minutes), etc. So you can vary the period of the periodic task to get the resolution that you want.

    You can use a totalizer outside of the AOI or incorporate it in the AOI. If you put it in the AO! you might want to add 

    GSV(WALLCLOCKTIME, ,DateTime, Clock.Year); Date, Time, etc This would be used to trigger the time that the totalizer resets (time of day)

    I created a user defined datatype called DateTime and used it inside of the UDT for the Clock tag. Ie a tag named Clock of the type DateTime. If this interests you at all I can cut and paste the UDT structure here tomorrow. It's late here and I'm not typing this on my programming computer or I would add it now.

    Of course you could forgo all of this and just do what the post above mine says. Just remember that this is a value per unit time calculation and time is an important part of the calc / totalization.

    This all sounds complicated but it's really not. If you sample every second you'll get kWs in the totalizer. If you sample every hour you'll get kWh in the totalizer. If you sample every minute then you get kWm... etc. Sample time depends on how much resolution you want.

     

     

    Plz Share with us yours UDT, and screenshots of ur Ladder Logic


  3. Thanks a Lot Sir Steve Bailey you were always here to assist Us!

    But Can Anyone figure Out what i am doing wrong that not letting me to display 32bit data.

    I have checked the satec PM130EH MFM meter modbus register manual, found there two sets of 16bit scaled energy counters/registers one is lowOrder & other is highOrder.

    And done a Conversion for getting the desired output without altering any variable's data type(as on doing so it generates error10808) and validate my project which generates no error but on uploading data to GE IP controller .. Nothing fruitful happens on cim HMI screen.

    Steve Bailey as you have previously assisted me ..on how to get 32bit data from 16bit registers, i have attached pics of LD on which i have made some changes (and i have 4days left for activating PME thats Y iam able to do modifications!)

    Is i am getting it totally wrong??

  4. Actually i was working on getting the 32bit large data by 2-16bit consecutive addresses and doing little convertion of adding high order and low order datas to get my energy kwh readings which is greater than what a 16bit data can holds.

    But on validating it generates error code 10808, may be i have to change the data type of my kwh output from workbench too??

    But workbench is logoff , asks for Management logOn!


  5. I cant able to make any changes on the points (datatype from INT to DINT) on cimplicity workbench  everything thing is greyout!!

    i checked and found that the workbench has a change management logOn option asking to logon!

    Which asks for user name and password!!

    And No one here Now has the user name or its password!!

    what to do now on such cases , Also on doing modifications on logic developer validating project generates error  may be due to mismatch data type of that associated point on workbench.

  6. Since From 5th of jan.2017 its been 2weeks i didn't get my query answered on my level.

    :(  Sry.. !

    " In the GE PLC, a 32-bit integer resides in two consecutive %R addresses. You appear to only be displaying one of them "

    Now, Do i have to create 2 consecutive %R addresses for each Feeder's PowerMeter as i cant add another Address consecutive to the present one as all of them already associated to other Points :( ,

    To do the same, Is there Other Easy & Simple way i am totally missing ??

     

    Thank You very much for yours valuable Reply.
    Sry, I am New to GE-Cimplicity Platform.


  7. Here Satec MFM Power Meter Shows :

    1970698 kWh (HT-MOTOR-01) but On SCADA It Shows as Only 0698 i.e 698.

    1560714 kWh (HT-MOTOR-03) Showing as Only 0714 i.e 714 Only.

  8. I am Facing Problem Getting Kwh Readings From My Satec MFM(PM130-PLUS), Required for an easy & reliable Monitoring On Energy Consumption .

    Connected via RTU Slave Interface with SCADA User Interface (GE_Cimplicity).

    Here's what happening :

    Actual Kwh Reading has 8_decimal data digits on MFM LED Display but on Cimplicity SCADA User Interface Screen It only able to Display it as 4_Decimals point digit,

    eg, 63290058 kwh shows as 0058 ,

    and 15299999 kwh shows as 9999 ,

    and then 15300001 kwh shows as 0001 i.e 1 only!

    Plz Do a Rply , your slight approach to my Query Will be highly Appreciated!! :)
