LED display Color Meaning

SF
Red, flashes
System error:
Flashes (approx. every second), if the configuration

LINK Green, continuous
Connection via the RJ45 interface:
Ethernet connection has been established
RX/TX Green, flickering Ethernet activity:
Data are being received and transmitted via the
Ethernet
Note:
A packet received via the Ethernet is not necessarily
intended for the CP 243-1. The CP 243-1 initially
accepts every packet transmitted on the Ethernet.
Only then does it decide whether the package is in-
tended for it.
The RX/TX LED also flashes as soon as the
CP 243-1 attempts to send a packet if the Ethernet
cable has been unplugged.
