Connecting to the CX81xx

Before you can work with the CX81xx you must connect your local computer to the CX81xx (target system). Then you can search for devices such as EtherCAT terminals with the help of the IP address or the host name.

The local PC and the target system must be connected to the same network or directly to each other via an Ethernet cable. In TwinCAT a search can be performed for all devices in this way and project planning subsequently carried out.

Requirements for this step:

Establish a connection as follows:

1. In the menu at the top click on File > New > Project and create a new TwinCAT XAE project.
2. In the tree view on the left click on SYSTEM, and then Choose Target.
