Create a Calculation Collector
Before you begin
- Deploy Proficy Historian for Azure Cloud.
- Install collectors. You
can install them on-premises or on a VNet (which can be different from the one
on which Proficy Historian for Azure Cloud is deployed). Important: If installing on a VNet, it is recommended that you install the Calculation collector on the virtual machine deployed in the same VNet the Data Archiver is running.
About this task
Features: The Calculation collector performs calculations on the following values:
- Current values of other Historian tags in the same archiver.
- Previous raw samples of other tags in the same archiver.
- Calculated values of other Historian tags in the same archiver, such as minimum, maximum, average, or standard deviation. You can specify a time range for these calculations or perform a filtered query. You can use the resulting single number in a calculation.
- Interpolated values of other Historian tags in the same archiver.
- Any data retrievable using a VBScript, file I/O, ADO, and so on.
- The Calculation collector can keep a history of the calculated values.
- It can perform thousands of calculations per second. Therefore, it is generally preferred to a VB SDK program performing the same functions.
- It can perform calculations on data stored in the following sources:
- A SCADA database (such as iFIX)
- A VB SDK program
- A Historian collector (using input scaling)
- By the Calculation collector
- The Historian OLE DB provider
- Reporting tools such as Crystal Reports
- The Historian Excel Add-In
Procedure
- Run Command Prompt as an administrator.
- Run the AzureCloudHistorianConfigurationUtility.exe file. It is provided along with the collectors installer. After you install collectors, it will be available in the C:\Program Files\GE Digital\Historian Cloud Config folder by default.
-
Enter the number corresponding to creating a collector instance.
A list of collectors that you can create appears.
- Enter the number corresponding to the collector that you want to create.
-
Enter the following details:
Field Description Interface Name Enter the name that you want to provide for the collector instance. Azure Load Balancer IP Enter the Azure Load Balancer IP. A value is required.
Tip: To find the Azure Load Balancer IP:- Go to the Azure portal.
- Go to the Resource Group that was specified during deployment.
- Select the cluster_name-IP to access the resource of type Public IP Address.
- Select or copy the IP Address.
Username Enter the username to connect to Proficy Historian for Azure Cloud. A value is required. Password Enter the password to connect to Proficy Historian for Azure Cloud. A value is required. Tip: For the default user, ihCloudHistAdmin, this is the value you entered in the Password field at the time of deployment.The Calculation collector is created and started.
