SIMATIC IOT2050
102 Operating Instructions, 03/2024, A5E39456816-AF
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.
You can use any COM port as an RS232, RS422 or RS485 interface through the software-
controlled interface parameter assignment.
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)".
