LEDs for displaying the CP communication status

In addition to the LEDs that signal the CP state, the following LEDs provide information about the status of the CP interface to Industrial Ethernet.

Table 4-1

LED			Display			Meaning

RX/TX (green)					The CP is sending/receiving over Industrial
					Ethernet
					Note:
					Sending / receiving over PROFINET IO is
					not signaled here.

P1 / P2					Port has no connection to
(green / yellow)					Industrial Ethernet.

				green	Existing connection over port to
					Industrial Ethernet (LINK status).

				green /	LED flashes yellow (constant light green):
				yellow	Port sending/receiving over
					Port sending/receiving over
					Industrial Ethernet or PROFINET IO.
					Note:
					All received / sent frames are signaled for
					each specific port including those simply
					forwarded by the switch.

P1 / P2				yellow	Continuous data transfer at the port over
(green / yellow)					Industrial Ethernet (for example
					PROFINET IO).

Legend:	(colored) on		off	(colored) flashing		“−” any
