Error Meaning
code
300 Possible causes:
H
• The process signal is faulty.
301
• The sensor is defective.
H
• The configured discrepancy time is
302
H
too low.
• There is a short-circuit between the
303
H
cable of an "unconnected sensor"
and the sensor supply cable.
• Wire break in the line of a "connec‐
ted sensor" or the sensor supply ca‐
ble
• An error occurred during the dis‐
crepancy check.
307 Possible causes:
H
• The internal sensor supply is short-
circuited to ground.
• Impermissibly high electromagnet‐
ic interference is present.
See the note below
message.
30D No valid PROFIsafe address is stored in
H
the retentivity memory.
Possible causes:
• Initial commissioning
• Deliberate parameter change of the
PROFIsafe address
• Deviation between set and actual
configuration of the plant
30E F_source_address and F_destina‐
H
tion_address parameters invalid
310 Too many signal changes have occurred
H
within the time configured with the
"Monitoring window" parameter.
• The "Monitoring window" setting is
too high.
• The "Number of signal changes" pa‐
rameter setting is too low.
• A momentary interruption/short cir‐
cuit of the sensor cable (loose con‐
tact) is present.
• Impermissibly high electromagnet‐
ic interference is present.
• The sensor/switch bounces.
• The sensor is defective.
Remedy
• Check the process signal.
• Replace the sensor.
• Check the parameter assignment of
the discrepancy time.
• Check the process wiring.
• Eliminate the overload.
• Eliminate the short circuit in the
process wiring.
• Check the "Sensor supply" parame‐
ter.
regarding this
*1)
• Eliminate/reduce the electromag‐
netic interference.
• Assign the PROFIsafe address during
initial commissioning or when delib‐
erately changing parameters.
• Check the consistency between the
nominal and actual configuration.
Check F_source_address and F_destina‐
tion_address parameters
• Check the "Monitoring window" pa‐
rameter.
• Check the "Number of signal
changes" parameter.
• Check the process wiring.
• Eliminate/reduce the electromag‐
netic interference.
• Replace the sensor.
