Case 2 – Accessing the Allen- Bradley PLC via integrated Ethernet port

In this scenario, the CIP client sends some data into the CPU module using the integrated Ethernet port. In a CPU module with integrated Ethernet port, the Ethernet port is in the same slot as the CPU module.

The CIP client in the MindConnect sends a request package to the CPU module at 192.168.0.32 addressing the processor module in slot 0.

Following the previous schema, the above image represents the communication path (route parameters).

Following the previous made explanations, the CIP message travels first through the processor module to the backplane and it returns back to the processor module for interpretation. For such situations, it is possible to use an abbreviated communication path only containing the IPv4 address.

The MindConnect block uses the parameter "slot" to form the communication path (route parameters).
