Question

Why can I see my P3-550 CPU in the PAC Connections Dialog, but I can not connect to it?

Answer

The most common reason for this is a conflict in the Subnet Mask in your Ethernet configuration between your PC or Laptop and the P3-550. The discovery method used to find connected CPUs on the network is different from the method used to connect and communicate to the CPU, which explains why you may be able to see the CPU, but not connect to it. See the Communications Ethernet topic.
