5.2 Displays and Controls
The seven LEDs on the front of the gateway signal the following:
power The gateway is sufficiently supplied with power.
PB active LED on: The PROFIBUS communications are active.
LED off:PROFIBUS communications are inactive.
config err A configuration error is imminent or no PROFIBUS communications
are taking place (when the "PB active" LED is not illuminated). This
means that with configuration errors, at least one projected slave is
missing or the actual configuration data does not correspond with the
reference configuration data for a projected and recognized slave.
U AS-i The AS-i line is sufficiently supplied with power.
(AS-i Flag "APO").
AS-i active Standard operation is active (AS-i Flag "Normalbetrieb").
prg enable Automatic address programming is possible
(AS-i Flag "Auto_prog_available").
Precisely one slave is missing in the protected operating mode. This
slave can be replaced with a slave of similar design and an address
of 0. The gateway automatically programs the new slave to the faulty
address and thereby resolves the configuration error.
prj mode The gateway is in the projection mode
(AS-i Flag "projecting_active").
