11.2.5.7 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.
11.2.5.8 TCP/IP Interface (F5
hex
)
The “TCP/IP Interface Object” provides for the configuration of the TCP/IP
network interface of a fieldbus coupler/controller. Examples of configurable
objects include the IP address, the network mask and the gateway address of the
fieldbus coupler/controller.
The underlying physical communications interface that is connected with the
TCP/IP interface object can be any interface supported by the TCP/IP protocol.
Examples of components that can be connected to a TCP/IP interface object
include the following: an Ethernet interface 802.3, an ATM (Asynchronous
Transfer Mode) interface or a serial interface for protocols such as PPP (Point-to-
Point Protocol).
The TCP/IP interface object provides an attribute, which is identified by the link-
specific object for the connected physical communications interface. The link-
specific object should typically provide link-specific counters as well as any link-
specific configuration attributes.
Each device must support exactly one instance of the TCP/IP interface object for
each TCP/IP-compatible communications interface. A request for access to the
first instance of the TCP/IP interface object must always refer to the instance
connected with the interface, which is used to submit the request.
