7.4 Repair error and reintegrate
Remedy
The error correction of the HMI device should be undertaken depending on the type of error
recognized:
Error Possible causes of error Remedy
Short-circuit in the sensor Eliminate the short-circuit.
Cross-circuit in the sensor Eliminate the cross-circuit.
Short-circuit
Internal error Replace the HMI device.
Serious error Internal error in the HMI device Replace the HMI device.
The process signal is faulty.
The sensor is defective.
Check the process signal.
Replace the sensor if needed.
Discrepancy error
(1oo2 evaluation)
Short-circuit between the sensor line
and the sensor voltage supply line.
Eliminate the short-circuit.
The HMI device does not match the
configuration.
Correct the configuration.
Check the communication paths.
Configuration error
Configuration incorrect Correct the configuration.
PROFIsafe address
deviation
The PROFIsafe address on the HMI
device is set incorrectly.
Set the same PROFIsafe address in
the SIMATIC manager, HW Config
and on the device. This address must
be unique. See section "Setting the
PROFIsafe address (Pag
e 92)".
The communication between the
fail-safe controller and HMI device is
interrupted, for example, due to a
defective PROFINET connection or
EMI.
Check the PROFINET cable.
The PROFIsafe monitoring time set
too low.
Increase the value of the
"F_WD_Time" parameter in the
SIMATIC Manager, HW Config.
Communication error
The configuration of the HMI device
does not match the safety program.
Compile the safety program again.
Then download the configuration and
the safety program to the fail-safe
controller.
Non-permissible
sensor evaluation
An invalid value was transferred for
the setting "Evaluation of the
sensor".
Check the setting. Check the version
of your GSDML-file. Load a new
GSDML file.
Version conflict The HMI device recognized an
invalid combination of firmware.
Update the device firmware
completely and bring it to the current
state.
