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
24 23
16
15
14
12 11
0
SI
SE
S/P
PS
Data Block Number
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
