Object directory

The manufacturer-specific, list-oriented entries in the object directory are explained below.

8.1

Survey of object directory - manufacturer-specific section

Note: The overall object directory is designed dually (from index 2001; from index 3001) to

permit equal objectswith different data types.

Index table structure:

The index is a 4-digit number in hexadecimal notation with the following structure.

MSB

Configuration mode:

Configuration changes such as output allocations or span end values are not taken over on-line.
For changing these parameters, KS800 must be switched to configuration mode. Mode switch-
over is via SDO access.

Index 2008 (OPMod):

value = 0 configuration mode
value = 1 normal mode

For changing data identified with rw

*

) in the object directory, OPMod must be set to 0. The

new parameters are taken over when changing the OPMod back from 0 -> 1 subsequently.

Used data-formats:

Unsigned8: 8-bit-value, without sign, range 0 ... 256
Unsigned16: 16-bit-value, without sign, range 0 ... 65535
Fixedpoint1: 16 bit-integer-value with 1 fixed digit behind the decimal point, within
-32767 ... +32767. When interpreting these values, the last digit is considered as a digit behind
the decimal point, e.g. 12345 means 1234,5 (

°

C), or 873 are 87,3 (%).
