In this case, the additional IPv4 address of will be set properly and the Auto-ip connection can be established.

In other words, the network adapter must be enabled and configured at the moment the direct connect utility is enabled. When this is present, CX-Programmer can 'find' the CP1L-EL/EM unit and a connection can be established.įor example, if the network adapter (connected to the CP1L-EL/EM) is disabled at the moment of enabling the direct connection utility, the IPv4 function is not achieved properly when the network adapter is later enabled. Look for the presence of an additional IPv4 Address of. It is then necessary to disable and re-enable the Direct Connection Utility before attempting the Auto-IP function. The Direct Connection Utility functionality can be verified via the commandline (cmd.exe utility) using the ipconfig command. In some cases, it could already be enabled but no connection is achieved. The Direct Connection Utility must be enabled to use the Auto-IP ( CP1L-Ethernet Online) function.

the adapter where the PLC is connected to. To correct this problem, use the DirectEthernetUtility (Direct Connection Utility) installed with CX-One.įirst of all make sure that you selected the correct network adapter.
