SCADA connect pump_status importing problems

Hi guys,

I try to build a robust SCADA connect model, but faced some very weird issues:

  • Importing historical overrides provides me exactly the opposite controls: When my SCADA data indicates status=1 (pump is ON), the import function adds a control to turn off the pump.
  • May Pump_status be enumerated the opposite way that would seem to be logical (1=off; 0=on)? Please confirm that what does 0 and 1 mean for pump_status!

Importing initial settings:

  • The last SCADA signal value for the two pumps were 0 (as shown below).
  • The initial setting for one of my pump was 0, for the other one was 1. The only way I could set my pump OFF initially was to add a control override in SCADAConnect simulator.

The lines from the Log file related to these signals:

2017-03-29 15:11:41: Invalid data for SCADA element: Ferihegy_Rcs_2_PMP_status

2017-03-29 15:11:41: Imported SCADA element: Ferihegy_Rcs_4_PMP_status to element: Ferihegy_Rcs_4, value: 0, quality: Good.

I've got no idea, why one of the signals considered "Invalid data" or "Invalid context", and others are not. It seems like 'Ferihegy_Rcs_4_PMP_status' signal is good and everything is fine, except controls are turned around.

Additional information:

  • All SCADA signals were connected by ODBC (.xlsx)
  • No signal value mapping was done
  • Time tolerance was set to 30 min as default
  • Simulation Start Time was 2016.05.26 00:00:00
  • Simulation period: 24 hours
  • Labels did not contain any location specific characters (although SCADA signal names did!) 

Do you know, what is the problem with my model? I can send it via confidential sharing.

Best regards,

  • Hello Attila,

    Most likely the raw values in your SCADA signals need to be mapped to values that WaterGEMS can properly interpret. This is done by way of the "Signal Value Mappings" tab in the database source. From the Signal Mapping window, right click on your database source, choose "Edit Database Source", then click the "Signal Value Mappings" tab.

    You can read more about this in the section of the below article titled "Signal Value Mapping for translating SCADA signal values and formats" and in the Troubleshooting section under "The pump status was not displayed after computing the model."

  • Hi Jesse,

    Thank you for your answer! Mapping did solve the "turned around" control (although the (mapped) 'signal value' is 1 for On and 0 for Off and Raw signal value is blank), but the initial status issue is just the same. I tried to modify the time tolerance to see if that's the source of problems, but it made no difference.

    Do you have any idea?

  • Hello Attila,

    I'm not quite sure I follow. Are you able to reproduce in a local file version of the SCADA data source (such as an Excel spreadsheet), so that the files and exact steps to reproduce can be provided? These can be sent using the following method:
