For unique labeling, the LAN interfaces are numbered on the enclosure. The numbering by
the operating system can differ. Siemens recommends you use shielded ethernet cables.
2
You can use any COM port as an RS232, RS422 or RS485 interface through the software-
controlled interface parameter assignment.
3
Termination with 120 Ω terminal resistance can be set with the software.
The maximum cable length is 1000 m under the following preconditions:
•
Data signaling rate is below 90Kbps
•
Using twisted pair copper wire of 24AWG or larger diameter
Additional information on parameter assignment is available in the SIMATIC IOT2000-Forum,
see section "Software and commissioning (Page 35)".
