SIPART PS2 with PROFIBUS PA
Operating Instructions, 05/2019, A5E00127926-AC
Functions/operations using PROFIBUS PA
Cause
The lower end stop is beyond the
set tolerance.
A run time overshoot was detec‐
ted. In all probability, the energy
(compressed air) is not available.
-
Power was fed to the device.
SIMATIC PDM was used to trig‐
ger a warm restart.
The internal watchdog has re‐
sponded.
The device was reset to factory
settings.
To determine the cause, check in
DIAGNOSTICS_EXTENSION
and DIAGNOSTICS_EXTEN‐
SION_2 which diagnostics event
has triggered the message.
The parameterized characteristic
curve does not have the required
monotony, number of support
points, or the x values are not ar‐
ranged in 5% distances. The orig‐
inal characteristic curve is used
further.
You have changed the PROFI‐
BUS identification number param‐
eter during the active cyclic oper‐
ation. The device reports the iden‐
tification number violation and dis‐
plays a failure warning. In case of
a warm restart, the device no lon‐
ger participates in the cyclic trans‐
fer of useful data without chang‐
ing the system configuration.

Further information about the trig‐
gering diagnostics event is avail‐
able in DIAGNOSTICS_EXTEN‐
SION and DIAGNOSTICS_EX‐
TENSION_2.
9.3 Cyclic data transfer
Measure
Check the valve. Flow restrictors
and/or the seat ring are probably
worn out.
Establish the compressed air sup‐
ply and check the feed lines.
-
Check the cabling and the supply
unit.
-
Depends on the triggering diag‐
nostics event.
Modify the configuration data
(change the GSD) such that it is
consistent with the identification
number set in the device.
