13E Overflow of the diagnostic memory. Not
H
all pending diagnostics could be sent.
This error can result in deactivation of the
module up to switching on/off of the
power supply.
300 The discrepancy time set for 1oo2
H
evaluation was exceeded.
Possible causes:
301
H
• The process signal is faulty.
302
H
• The sensor is defective.
• The configured discrepancy time is too
303
H
low.
• There is a short-circuit between an
unconnected sensor cable and the
sensor supply cable.
• Wire break in connected sensor cable
or the sensor supply cable
• An error occurred during the
discrepancy check.
305 An error has occurred during the
H
plausibility check of the input signal
between the processors.
Possible causes:
• The input signal is faulty. For example,
through an impermissibly high
electromagnetic interference.
• There is a high-frequency input signal.
For example, through reciprocal
interference of the sensors, or the
signal lies above the sampling
frequency of the input signal.
• A momentary interruption/short-
circuit of the sensor cable (loose
contact) is present.
• The sensor/switch bounces.
306 Possible causes:
H
• There is a short-circuit of the internal
sensor supply with L+.
• There is a short-circuit of two sensor
supplies.
• The capacitance of the connected
sensor for the configured test time is
too high.
• The sensor is defective.
Eliminate the previously reported error.
• Check the process signal.
• Replace the sensor.
• Check the parameter assignment of
the discrepancy time.
• Check the process wiring.
You must eliminate the occurred error
within 100 hours if no short-circuit test
has been configured for the
corresponding sensor supply.
• Use shielded cables to reduce the
EMC effects.
• Reduce the input frequency.
• Check the wiring of the sensor.
• Eliminate the short-circuit in the
process wiring.
• Check the configured test time and
the process wiring.
• Replace the sensor.
