Q12195 - HOWTO: Supported Variable Configurations for Interface Q12180

Wonderware Historian Variable Cross Referencing

To configure a variable to summarize values from Wonderware Historian (InSQL), select Edit/View Variables in the client and select the Interface tab.  Then click Interface To radio button. The drop down box next to the option is now enabled, click the drop down arrow and choose the Wonderware Historian interface name (name given when configuring the interface).

Note: Tag is CASE Sensitive

FIELDS

Tag: The SCADA Tag to import data from. Note: Tag is CASE Sensitive.  Data will be pulled from the Wonderware Historian table named History by default.  To specify a different table in the Historian to pull data from, simply put the table name in square brackets ("[tablename]") followed by a dot (".") then the tag name.   Note:  Wonderware InSQL version 7.1 did not have a "History" Table/View, therefore if using 7.1 use the v_AnalogHistory table.  Later versions (8.x, 9.x,...) of Wonderware Historian have the History view.  

Example Tag Settings:

WTP_WW_FLO_VLV.PosEU - Will pull data from the History table in Wonderware Historian where TagName = WTP_WW_FLOW_VLV.PosEU

[v_AnalogHistory].WTP_RAW_TURB.TuEU - Will pull data from the v_AnalogHistory view in Wonderware Historian where TagName = WTP_RAW_TURB.TuEU

If the Browser is configured (see Browser Setup), the ? button can be used to browse the available tags:

 

The tag browser lists all tags listed in the Historian Tag table.  The TagType indicates the type of data (analog, discrete, etc...).  The following table describes the TagType field (SELECT * FROM TAGTYPE):

TagType TagTypeName
1 Analog
2 Discrete
3 String
5 Event
7 Structure

Select a tag and then click OK and you will be back at the Edit Variable screen.  Click on the column headers to sort by column and use the Search function to filter the list to find a particular tag (Search looks at both the TagName and Description and is not case sensitive). 

 

NOTES:  You do not need to specify the tablename if you want to pull data from the History Table/View.  If you specify the table/view in square brackets, the table MUST have the following fields:  DateTime, Value, TagName, wwRetrievalMode, wwRowCount.  The History, v_AnalogHistory, and v_DiscreteHistory views have these required fields. 

 Statistic:  Sets how to summarize the Wonderware data for import. The following table shows the supported statistics with the actual query used for a daily parameter variable with Start Time set to 00:00 and Stop Time of 23:59.  Tag is set to 'ETP_RW_FlowTotal.FlowTotalOS', therefore the History View will be used.

* The INVENTORY statistic will ignore non-numeric values and will hold last value for the time slot difference. In the following example, the 12:03 AM value will be skipped and the difference will be between 9.67 (12:02 AM) and 9.25 (12:04 AM) when evaluating the 12:04 AM inventory value.

Scale Factor: This is the value to multiply the result by when using parameter variable types. Commonly used to convert from one unit base to another. For example to convert gallons per minute (GPM) to gallons per day (GPD), set the scale factor to 1440 (1440 minutes per day).



Filter: All three fields must have numeric values or the word None (as shown). The Low Range and High Range will crop data from the source. For example to eliminate negative numbers from a particular tag, set the Low Range to 0 (zero) - this will get any values equal to or greater than 0 (zero). The Deadband is used for the statistic Inventory and will elliminate noise levels up to the value specified. For example, if you enter .5 next to Deadband, any value change of .5 or less, will be ignored.



Start/Stop Time:   Sets the time period within the variable's frequency to summarize data for.

    • Start Time will set the beginning of the time slot for this variable.
    • Stop Time will set the ending time for the time slot.
    • Same Day as Start is only used by daily variables and it means the stop time is on the same day as the start time.
    • Day After Start is also only used by daily variables and it means the stop time is a day after the start time.

Note: Start and Stop Time can be used for daily detail variables (i.e. Hourly, 15 Minute, etc...) to set the part of each slot to get data from.  For example, for an hourly variable, set to Start Time to 00:15 and Stop Time to 00:45 to only look at data between 15 minutes and 45 minutes of each hour. 

 

Filter Data:  Used to filter what times the SCADA data should be analyzed.  Example, you want to get the maximum filter turbidity but ONLY WHEN the Filter to Waste value is closed (i.e. the tag F1_WASTE_VALVE_POS = 0). 

Condition Description
<, >, =, <=, >=, <> Summarize values based on statistic when the Filter Tag is <, >, =, <=, >=, or <> to the value specified.
CYCLESTO Summarize values based on statistic when the Filter Tag changes to Value specified.
ACT(n) After Cycles To - Summarize values based on statistic looking at data that is n minutes after the Filter Tag changes to the value specified.   
BCT(n)

Before Cycles To - Summarize values based on statistic looking at data that is n minute before the Filter Tag changes to the value specified.
NOTE: There is a work around setting for this filter function to work with the City of Ventura's Interface.  The setting: BCT_TWEAK_VENTURA must be set to 1.  Ex: 1

GOES>(n) Summarize values based on statistic looking at data that is offset n minutes from when the Filter Tag goes above the value specified.  N of Zero (0) means get data in the same minute, 1 means 1 minute after, -2 means 2 minutes before.
GOES<(n) Summarize values based on statistic looking at data that is offset n minutes from when the Filter Tag goes below the value specified.  N of Zero (0) means get data in the same minute, 1 means 1 minute after, -2 means 2 minutes before.

NOTE: The CYCLESTO, ACT, etc... conditions are not on the pulldown list, simply type the condition. 

How filtering works:

The Interface grabs data for the source tag and the filter tag once a minute using retrieval mode of cyclic and pairs up the values for each minute.  It then loops thru the records and only analyzes source tag values when the fitler tag meets the criteria. 

Example: The following example gets the Minimum Chlorine Residual when the Tank Level is above 16.5:

Query:

select source.timestamp,savg,favg from
(select MIN(Value) as savg, cast (cast(month(DateTime) as varchar) + '/' + datename(day,DateTime) + '/' +datename(year,DateTime) + ' ' +  datename(hour,DateTime) + ':' + datename(minute,DateTime) + ':00' as datetime) as timestamp
from dbo.AnalogHistory
where DateTime >= '2015-04-29 00:00:00' and DateTime < '2015-04-30 00:00:00' 
and TagName='NPS_36IN_TTL_CL_RES.PvEU'  AND value is not null  AND wwRetrievalMode = 'Cyclic' AND wwRowCount = 1440
group by cast (cast(month(DateTime) as varchar) + '/' + datename(day,DateTime) + '/' +datename(year,DateTime) + ' ' +  datename(hour,DateTime) + ':' + datename(minute,DateTime) + ':00' as datetime)) source
left outer join 
(select MIN(Value) as favg, cast (cast(month(DateTime) as varchar) + '/' + datename(day,DateTime) + '/' +datename(year,DateTime) + ' ' +  datename(hour,DateTime) + ':' + datename(minute,DateTime) + ':00' as datetime) as timestamp 
from dbo.AnalogHistory where DateTime >= '2015-04-29 00:00:00' and DateTime < '2015-04-30 00:00:00'
and TagName='WFN_WELL37_1B.PumpingLevelEU'  AND value is not null  AND wwRetrievalMode = 'Cyclic' AND wwRowCount = 1440
group by cast (cast(month(DateTime) as varchar) + '/' + datename(day,DateTime) + '/' +datename(year,DateTime) + ' ' +  datename(hour,DateTime) + ':' + datename(minute,DateTime) + ':00' as datetime)) filter
