The following image shows the architecture of AVEVA Workflow Management Connector for System Platform:

AVEVA Workflow Management and System Platform Integration

A WCF (Windows Communication Foundation) layer integrates the System Platform with AVEVA Workflow Management. An AppObject named WorkflowGateway, placed in the ArchestrA environment, manages the Outbound and Inbound communication between these layers.

• Outbound connection contains information related to the WCF service hosted inside the workflow engine (windows service). Outbound connection is used to trigger workflow during events in ArchestrA. The same connection is also used to get information from AVEVA Workflow Management layer.
• Inbound connection contains information related to the WCF service hosted inside the Runtime node as a windows service. Inbound connection is used to perform read/write attribute operation and also to synchronize user information from ArchestrA layer to AVEVA Workflow Management layer.
