Status
Normal operating status
Device diagnostics are run-
ning and/or diagnostic
data are on hand.
Device is connected cor-
rectly to the bus node, but
internal communication is
faulty.
A connected device was re-
moved after commissioning
Incorrect device connec-
ted:
– Device detected that is
not I-Port compatible
– Non-configured device
detected
If X1 and X2 are flashing
red simultaneously:
– No device connected to
the bus node
– Configuration error
Meaning/error elimination
Device is connected correctly to the
bus node.
Data connection between bus node
and device is built up.
•
Device diagnostics can be read via
fieldbus communication (if activ-
ated via DIL switches on the bus
node)
•
Check I-Port connection: cables,
plug connectors, signal
transmission (error counter
overrun)
•
Restart the bus node (by switching
the power off -> on)
•
Use an I-Port-compatible device
(e.g. appropriate valve terminal)
from Festo
•
Connect at least one device
•
Restart the bus node (by switching
the power off -> on)
