12.3.5.8 Connection Manager (06
hex
)
The “Connection Manager Object” provides the internal resources that are
required for the input and output data and explicit messages. In addition, the
administration of this resource is an assignment of the “Connection Manager
Object”.
For each connection (input and output data or explicit), another instance of the
connection class is created. The connection parameters are extracted from the
“Forward Open” service, which is responsible for establishing a connection.
The following services are supported for the first instance:
• Forward_Open
• Unconnected_Send
• Forward_Close
No class and instance attributes are visible.
