KS 800 CAN-Interface
8 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 LSB
Format Function block Function Parameter no.
2=Fixed Point Format 0=Device current number current number
3=Float Format 1=Input
2=Controller
3=Alarm
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 (%).
