Tab allows you to setup a SCADA Interface within Equipment Entry.  Equipment can be cross referenced to SCADA points and meter readings can be imported using optional interfaces.  Interfaces are available for GE Intellution, Wonderware, Cimplicity, RS View, etc.... Contact Hach for more information on interfaces. Note: In order to enable this tab, the Scada Interface for Equipment Meter Readings option must be checked in Options.  Also, the Metered option should be checked on the Equipment Entry form to indicate meter readings are to be tracked for this piece of equipment.

FIELDS:

Signal Tag The tag used to identify the field to import data from.
NOTE:  Each individual  company (Intellution, WonderWare, Cimplicity,ect.) will have a differant type of format for there signal tag.  Be sure and read the documentation that comes with each interface. In order to setup  the signal tags according to the formatting required for that software.

Statistic - Specifies how to pull data from the SCADA system.

• Last Good Reading - Takes the last reading for the day and places it in the Meter Reading Table.
  
• Add to Previous - Takes the maximum reading for the day and adds it to the last meter reading in Job Cal Plus for the equipment.  Add to Previous is typically used when the value to be transferred is the daily runtime and is reset everyday.  
  
• Accumulate Difference - Takes the last reading for the current day minus the last reading for the previous day and adds that value to the last meter reading.  Detects if the meter reading has rolled over.  For example:

Date	Last Readings	Meter Reading Stored
12/13/2012	950	14000
12/14/2012	985	14035 (14000 + (985 - 950) )
12/15/2012	10	14060 (14035 + 25 (Rollover assumed at 1000))
12/16/2012	42	14092 (14060 + 42-10)

If there is no value for the previous day, the current days last reading will be added to the last meterreading value found in Job Cal Plus.

Scale Factor Used as a multiplier to scale the statistic before placing the value in the database.  For example, if WonderWare is storing the number in tenths of hours use a scale factor of .1 to convert the reading to hours.  If WonderWare is storing the runtime in minutes, use a scale factor of 0.0167 (1/60) to convert the reading to hours.
