Hi,

Could you help me?

what to set user_prm_Data (3 to 4) under parameter assaigment in hardware configuration for X20IF1063-1

------------------------------------------------------------------------------------------
Split from Configuration of an profibus card.

Hello ahmaddedi;

The user_prm_data is a manufacturer module-specific parameter, and corresponds to the way the Profibus slave ASIC of your module is programmed and exchanges data with the master; as a Profibus user, you do not specify anything in the user_prm_data field. This is read from the module's GSD file and should not be modified.

Here are a few documents that could sghed some light on the subject:

- from Profibus International (the governing body for Profibus and Profinet):

User_Prm_Data: (O)

Manufacturer-specific field. Specifies the default value for User_Prm_Data. If this parameter is used, its length has to agree with the User_Prm_Data_Len.

Hope this helps,
