When using the Ethernet Fieldbus port for communication with WAGO-I/O-
PRO CAA, the PC and the controller must be connected physically via
Ethernet (refer to Figure 5-2 and 5-3 for typical network connections).
Additionally, the TCP/IP communication driver in WAGO-I/O-PRO CAA
must be setup correctly and the controller must contain an IP address (refer to
section 3.1.6.4 for assigning an IP address to the controller).
