5.1 Process Image
This section describes the process data. The structure of the process data depends on
which connection (connection 1, connection 2 etc.) is used between the EtherNet/IP
scanner and the module. The module offers multiple connections; a connection was se-
lected during configuration of the EtherNet/IP scanner.
