    - Configure a data source item for a resource
      This procedure is used to configure data source items for equipment, events, and workflows.
    - GE Historian Data Source
      The GE Historian data source allows you to connect to Historian servers to read from and write to Historian data tags. You add Historian tags to Workflow and then use those tags as data sources throughout Workflow.
    - OPC Client Data Source
      An OPC client provides direct access to data served by OPC Data Access (DA) servers without relying on GE Historian as a bridge between an OPC server and Workflow.
    - OPC UA Client Data Source
      The OPC Unified Architecture (UA) client provides direct access to data served by OPC UA servers.
    - Database Service Providers
      The database service provider allows you to connect to data sources and retrieve or update information for SQL and ODBC statements and procedures.

Data Type Conversions

Data type conversions happen automatically between compatible data types in Workflow.

When a specific data type is selected as the source and is bound to a different data type, if available, Workflow automatically converts the source data type into the destination data type.

Source Data Type	Converts to...
Boolean		Boolean, String, or Object
String		Boolean, String, Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, Single, Double, GUID, DateTime, TimeSpan, or Object
Byte		String, Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, Single, Double, or Object
Byte[]		Byte[] or Object
Byte[]		String, Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, Single, Double, or Object
Int16		String, Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, Single, Double, or Object
Int32		String, Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, Single, Double, or Object
Int64		String, Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, Single, Double, or Object
UInt16		String, Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, Single, Double, or Object
UInt32		String, Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, Single, Double, or Object
Single		String, Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, Single, Double, or Object
Double		String, Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, Single, Double, or Object
GUID		String, GUID, or Object
DateTime		String, DateTime, or Object
TimeSpan		String, TimeSpan, or Object
DataTable		DataTable or Object
Object		Boolean, String, Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, Single, Double, GUID, DateTime, TimeSpan, DataTable, or Object

Example

You can use a write activity in Workflow to write an int32 parameter to a string parameter. The int is converted to a string when the write occurs; for example, a 12 becomes “12”.
