GE Proficy Historian Interface
This document explains how to configure the subject interface for Machine Connect.
Setup
1. create a new "point" type Asset Class representing the “System” MC will interface with (you may name it anything. for example "North Plant 1 SCADA");
2. associate the Asset Class with a business line
3. for the new class define the following attributes:
| Type | Required | Key | Name | Description | Default Value |
|---|---|---|---|---|---|
| TEXT | Yes | MC_INTTYPE | Interface Type | Defines the interface type. | GE PROFICY HISTORIAN |
| TEXT | Yes | MC_OLEDB | OLE DB Connection String | Defines the connection string. | |
To connect an OLE DB client to a Historian server on a local connection (both software packages are on the same PC), use the following connection string:
Provider=iHOLEDB.iHistorian.1
To connect an OLE DB client to an Historian Server on a remote PC, use the following connection string:
Provider=iHOLEDB.iHistorian.1;PersistSecurity Info=False;USER ID=[Username];Password=[Password];Data Source=[Target]
4. create a new Workflow Class for that will tell MC what data to collect from the interface. You will create one for like frequency of data collection (for example "Hourly SCADA data" or "15 Minute Data");
5. check the “Machine Connected” checkbox;
6. associate the workflow with the same “Business Line” as the asset class created above;
7. associate the workflow with the asset class;
8. define one field for each tag you'd like MC to query:
| Type | Required | Key | Name | Description | Default Value |
|---|---|---|---|---|---|
| TEXT | Yes | {tag_name} | {tag_name} | Friendly name for the tag |
Note: “GE PROFICY HISTORIAN” is expecting the key value to represent the full tag name as queried from the IHRAWDATA table;
