Annex
C) Overview of the encoder functions
The specification of the measuring instruments contains functions for detailed diagnostics and functions
for the parameter setting of the position value. Tables A.1 and A.2 provide an overview of measuring
instrument-specific data for measuring instruments of class 1 and class 2.
These data are implemented as application-specific data of the communication functions.
Table A.1:
measuring instrument-specific data class 1 (CLASS 1), compulsory for all DP
measuring instruments
Function
Octet no.
