For unique labeling, the LAN interfaces are numbered on the enclosure. The numbering by the
operating system can differ.
You can use any COM port as an RS 232, RS422 or RS 485 interface through the software-
controlled interface parameter assignment. Possible parameters: "Auto-flow-control", "Onboard
termination", "Half-duplex" or "Full-duplex"

Termination can be set with the software.
Additional information on parameter assignment is available in the SIMATIC IOT2000-
Forum, see section "Software and commissioning (Page 29)".
