device manual AS-i DP - Gateway
R22
DP parameter invalid
The parameter setting of the Profibus master for the device is not valid.
Possible causes:
Setup of the parameter field is incorrect, length of the parameter field is not correct, the coding
of the individual parameters corresponds to the possible settings.
Rectification:
Adopt parameter field from the GSD file and modify it according to the specification.
R23
DP parameter download
The attempt to download the current / projected parameters of the AS-i slaves via the Profibus was unsuccessful.
Possible cause:
The slave to which the parameter was to be written was deleted from the list of detected slaves.
A timeout was found during the execution of the AS-i command “Write Parameter”.
Rectification:
Rewrite the Profibus parameters by separating the connection to the Profibus master.
R24
Missing positive CPTE edge
During communication with the master a change in the state of the control signal was not detected.
Possible cause:
Operating system software error.
R25
master: Unnormal operation
The master reports that it is not in the “Normal Operating Mode”.
Possible causes:
The master detects an AS-i voltage smaller than 22V and therefore changes into the “Offline Mode”.
The master has received a request from the operating system to change into the “Offline Mode”.
The master has found a transfer error in the communication with the operating system.
With the AS-i power supply connected the master detects that no slave is connected to the AS-i line.
Other causes which can lead to the error message directly after the device has been switched on:
Initialization of the master while the device is switched on was not successful.
The master has not yet received the projection nor the projected parameters from the operating system.
The master has not yet been started by the operating system.
R26
>> error message not activated at present <<
R27
Profibus PLC access violation
Not used in AS-i DP Gateway
R28
Execution password protected
A functionality of the device was requested which is not allowed with the current password.
Rectification:
Setting a higher password access in the "System Setup" -> "Password" menu.
R29
PC command unknown
An unknown command was received In the “Test Mode” operating mode of the device.
Rectification:
Sending a specified test command.
R30
PC checksum failure
An invalid checksum in the data flow was detected in the “Test Mode” operating mode of the device.
Rectification:
Configuration of the data flow according to the specification.
