Configure GE Intelligent Platform Drivers and Deadbands

About this task

If you want to add items of different data types to Historian using the OPC Classic DA collector to a GE Intelligent Platform v7.x driver or an OPC server, and you are using deadbands, you must manually modify the source address for each item you add. This is to specify the engineering unit (EGU) range for that item.

Procedure

  1. Access Historian Administrator.
  2. Select Tag Maintenance , and then select the item that you want to modify.
  3. Select Collection.
  4. In the Source Address field, add the following fields:|SIGNALCONDITIONING,LOWEGU,HIGHEGU,HARDWAREOPTIONS
  5. Repeat the steps for each item that you want to modify. If, however, you want all the items to use the same data type, change the settings of the following registry key: \\HKEY_LOCAL_MACHINE\SOFTWARE\In-tellution\Drivers\SI7\OPC\ItemDefaults. These values apply to all items not specified by the source address after you restart the driver.

Using Deadbands with the SI7 Driver

When you use the SI7 driver, it sets the global default values for EGU limits used for deadband calculations to the following values:
  • 1 Lo EGU = 0
  • 1 Hi EGU = 65535
  • 1 EGU Span = Hi EGU - Lo EGU = 65535

You may want change the default values for this driver if the items that you add use data types other than Integer (such as Float).

If, however, you want all the items to use the same data type, change the settings for HiEGU and LoEGU for the following registry key: \\HKEY_LOCAL_MACHINE\SOFTWARE\In-tellution\Drivers\SI7\OPC\ItemDefaults. These values apply to all items not specified by the source address after you restart the driver.
