7 Troubleshooting and diagnosis options
7.1 Optical displays
If all 4 LEDS are in the flashing mode (simultaneous fast flashing), an exception error
exists. In this case you can try to execute a re-start to put the measuring system into
operation again. If this doesn’t work, the device must be replaced.
7.2 PROFINET Diagnostic alarm
Alarms are part of the acyclic frames which are transferred about the cyclical RT-
channel. They are also indicated with the EtherType 0x8892.
In case of an
internal communication error
by the IO-Device a channel
specific diagnostic alarm (
UserStructureIdentifier
= 0x8000) is sent to the
controller. The transferred error number is 0x0070 = manufacturer-specifically. If this
alarm occurs, the measuring system is faultily, the IOPS bit is set to
BAD.
In this case
you can try to execute a re-start to put the measuring system into operation again. If
this doesn’t work, the device must be replaced.
In case of a
configuration error
by the IO-Device a manufacturer specific
diagnostic alarm (
UserStructureIdentifier
= 0x5555) is sent to the controller.
The transferred error number is 0x0002.
Also see chapter “Number of magnets” on
page 82.
In case of a
measurement error
by the IO-Device a manufacturer specific
diagnostic alarm (
UserStructureIdentifier
= 0x5555) is sent to the controller.
For this purpose
, Bit 0 must be set to “1” in the operating parameter
Option 1
. The
transferred error number is 0x0001.
Also see chapter “Option 1 (Diagnostic alarm -
A measurement error is present, if the magnet is outside of the measuring range or the
magnet minimum distance is too small.
7.3 Return of Submodule Alarm
By the measuring system a so-
called “Return-of-Submodule-Alarm” is reported if
● if the measuring system for a specific input element can provide valid data again
and in which it is not necessary to execute a new parameterization or
● if an output element can process the received data again.
In this case the status for the measuring system (submodule) IOPS/IOCS changes
from the condition
BAD
to
GOOD
.
