3.2 Identification Numbers (IDNs)
All operation data, parameters and commands of a Sercos slave can be accessed
using the service channel, the real-time channel or using S/IP and are addressed
using IDNs.
The Sercos-III-IDNs consist of 32 bits and are subdivided as follows:
31
SI
Data Block Number:
Contains the data block number or function group
Value range: 0...4095
PS, Parameter Set
Contains the number of the parameter set. Sercos specifies only IDNs with
parameter set = 0.
Value range: 0...7
S/P:
S = Standard IDN (S-0-nnnn)
P = Product specific IDN (P-0-nnnn)
Value range: 0: S, 1: P
SE, Structure element:
The Structure element is used to address the element (parameter).
Value range: 0...127 = Standard SE; 128...255 = Product specific SE
SI, Structure instance:
Contains the number of the parameter instance.
Value range: 0...255
Symbolic notation of a standard IDN:
IDN / S - <Parameter Set> - <Data block number> . <SI> . <SE>
Example, Encoder status:
