MindConnect EthernetIP - CIP Communication path (route parameters) settings¶
The CIP uses a method of encapsulating the messages adding communication path segments to the command segment. This leads to a longer and longer growing message as the number of routing stations grows.
As an example, the following simple layout is used to explain that fact.
The MindConnect is acting as a CIP client.
The CIP server is provided by a ControlLogix or CompactLogix.
Each CIP message contains the routing information to the target. Every time a bridge accepts such a CIP message it strips out its own address information and forwards the modified CIP message to the next addressee along the way. When there is no further routing information available the destination target has been reached and the CIP message will be interpreted. Once interpreted the response will be send the same way back the request came. This means each bridge keeps a reference to the request package.
