Hi Team,

I'm trying to communicate to a LS S100 VFD with a PROFInet coupling. I can communicate with using the WRREC but it's limited on the drive side. In order to get to all the correct parameters they suggest to use the PROFIdrive comminicaton.

When executing a 'PDRV_Param_Change_1' block I get the following errors:
PDRV1.wDiagCode: 16#C030
PDRV1.wAddDiagCode: 16#0800
With a PDRV_DiagInfo block it says the following: write record service: unknown wAddDiagCode 0x800

Please see the attachments.

Now I do have one parameter of the PDRV_Param_Change block that is unknown to me and is not described thuroughly in the documentation: PDRV1.bDriveObject.
From the documentation I read 'ID of the Drive Object' but no further explination is given. When I change the value the following error appears:
PDRV1.wDiagCode: 16#C030
PDRV1.wAddDiagCode: 16#B00A
This one is also unknown to the PDRV_DiagInfo.

Can someone shine light on the issue and what's going wrong?
If you need any more info please let me know.

Thanks in advance,
Carel

Hello Carel,
I assume that the error is generated by the ProfiDrive device because the object to be read does not exist or is protected. If it is possible to create a Wireshark Record, the error message must be in readable text. As I know, Profidrive uses WRREC and RDREC to read an object. WRREC writes the universal object with the information that the specific object is being read and in the next step the RDREC reads this object.
