SIPART PS2 with PROFIBUS communication
Operating Instructions, 09/2007, A5E00127926-07
Functions/operations using PROFIBUS PA
Cause
-
The temperature measured at
the device electronic unit has
exceeded one or more set
thresholds.
During operation, the memory is
constantly checked for the
checksum and write/read errors.
This message is generated in
case of an error.
-
The initialization process
required for the device
functioning has not yet been
carried out successfully.
Values obtained during the
initialization process cannot be
used.
The lower end stop is beyond the
set tolerance.
A run time overshoot was
detected. In all probability, the
energy (compressed air) is not
available.
-
Power was fed to the device.
SIMATIC PDM was used to
trigger a warm restart.
The internal watchdog has
responded.
The device was reset to factory
settings.
To determine the cause, check in
DIAGNOSTICS_EXTENSION
and
DIAGNOSTICS_EXTENSION_2
which diagnostics event has
triggered the message.
11.3 Cyclic data transfer
Measure
-
Check why the temperature is
beyond the specified range.
Replace the electronic unit.
-
Carry out the device initialization
process.
Carry out the device initialization
process again. Check the
relevant parameter settings.
Check the valve. Flow restrictors
and/or the seat ring are probably
worn out.
Establish the compressed air
supply and check the feed lines.
-
Check the cabling and the supply
unit.
-
Depends on the triggering
diagnostics event.
