Monitoring Functions and Diagnostic Functions

Watchdog for Cyclic
Communication
F4012 Incorrect I/O length
Diagnostic LED "H30"
P-0-4073, Field bus: diagnostic
message
DOK-INDRV*-MP*-02VRS**-FK01-EN-P
Monitoring Functions
As a standard, the time required for the watchdog monitoring function is
automatically calculated and configured. It is displayed in parameter
P-0-4075, Field bus: watchdog (in ms).
Note: The entry "0" in parameter P-0-4075, Field bus: watchdog
means that the watchdog monitoring function has been
deactivated!
When the error message F4012 Incorrect I/O length is generated, the
drive is in the PROFIBUS status "Data_Exchange"; the LED display "H30"
is active. The parameter channel is working but the data of the input and
output module are not processed internally.
Diagnostic Possibilities
The status of the field bus master communication of an IndraDrive device
is diagnosed via:
• LED display "H30" at the front panel of the controller
• diagnostic parameter P-0-4073, Field bus: diagnostic message
The LED display "H30" is active when the drive is in the PROFIBUS
status "Data_Exchange". This means that real-time data are exchanged
between IndraDrive device and master.
This parameter contains the status of the field bus master communication
in plain text. The contents of parameter P-0-4073 have the following
significance:

Master Communication
Significance
initialization value of the diagnostic message
A PROFIBUS-DP card has been recognized as
master communication and the hardware is
checked.
The hardware is okay; the PROFIBUS interface
is monitored in order to recognize the baud rate
used.
The baud rate has been found, the drive waits for
a parameterization telegram of the master that
contains its IDN (contained in the device data
sheet).
The IndraDrive device has received a valid
parameterization telegram and now waits for the
configuration telegram in which the master tells
the drive for which modules it is waiting for
input/output configuration.
The drive has received a valid configuration, it
exchanges real-time data with the master. The
communication is monitored by a watchdog.
The drive has received a valid configuration. It
exchanges real-time data with the master without
the communication being monitored by a
watchdog.
