The software inspects the writing of attribute 3 of assembly instances 101, 102

and 103. If the limit value has been exceeded, it is identified and, if necessary,

corrected. However, a write request is not rejected. This means that if less data is

received than expected, only this data is written. If more data is received than

expected, the received data at the upper limit is deleted. In the case of explicit

messages, however, a defined CIP is generated even though the data has been

written.

11.3.5.7

Connection (05

Because the connections are established and terminated via the connection

manager, the class and instance attributes of this class are not visible.

11.3.5.8

Connection Manager (06

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.

Port Class (F4

The "Port Class Object" specifies the existing CIP ports on the fieldbus

coupler/coupler. There is one instance for each CIP port.
