Parameter Data Structure

The VPC3+C evaluates the first seven data bytes (without

User_Prm_Data), or the first eight data bytes (with User_Prm_Data). The

first seven bytes are specified according to the standard. The eighth byte is

used for VPC3+C specific characteristics. The additional bytes are

available to the application.

If a PROFIBUS DP extension shall be used, the bytes 7-9 are called

DPV1_Status and must be coded as described in section 7,

“PROFIBUS DP Extensions”. Generally it is recommended to start the

User_Prm_Data first with byte 10.
