Cause
The AS-i master has detected
insufficient voltage on the AS-i cable.
Data exchange on the AS-Interface
has been stopped.
The ACTUAL configuration of the
AS-i slaves on the AS-i cable differs
from the CONFIGURED configuration
saved in the AS-i master.
Possible causes of short-term failures:
High levels of electromagnetic
•
interference are affecting the
AS-i installation.
Other possible causes:
The functional ground connection
•
to the AS-i power supply unit or
AS-i data decoupling module is not
connected to ground potential.
Protected operation:
•
A configured slave has failed or
there is an excess slave on the
bus.
Configuration mode:
•
A slave with address "0" has been
detected on the bus.
A ground fault is present between
AS-i+ and ground or between AS-i-
and ground.
Possible consequences:
Disruption of communication
•
Slave failure
•
Configuration error
•
Hazard as a result of secondary
•
faults
There is an unconfigured AS-i slave
with a default address or an A address
on the AS-i bus. The channel number
of the message shows the address of
the affected AS-i slave.
On the AS-i bus there is an
unconfigured AS-i slave with a B
address. The channel number of the
message indicates the B address of
the affected AS-i slave

Remedial measures
Check:
Voltage
•
Polarity on AS-i cable
•
Power supply
•
Check:
AS-i slave failure
•
Overload
•
Excess slave
•
Incorrect address
•
Incorrect slave type
•
EMC environment
•
Remove the
electromagnetic
interference.
Check:
Insulation fault on
•
AS-i cable
Sensor/actuator cable
•
Ensure that the ground
fault is rectified.
Change the
CONFIGURED
configuration in the
AS-i master or remove the
AS-i slave.
Change the
CONFIGURED
configuration in the
AS-i master or remove the
AS-i slave.
