108 Function Description

Table 90: Explicit Device ID (Upper 8 Bits) Object 0x2134

Sub-Index
0
7.4.9 Objects 0x9000 ... 0x93F0
For every I/O module there is an object in the information area (0x9000 to
0x93F0) with the Module PDO Group (SI9) and the Module Ident (SI10).
Additional information about Module Ident
You can read about Module Ident in more detail in "Function Description" >
"Object Dictionary" > "Structure of Module Ident".
The indices are assigned according to the following formula:
Index = 0x9000 + (number of the I/O module - 1) × 0x0010
7.4.10

Objects 0xF030 and 0xF050

Objects 0xF030 and 0xF050 concern two lists with the Module Ident's of the
connected I/O modules. The two objects serve to allow the master to compare
the node structure with an expected structure.
Additional information about Module Ident
You can read about Module Ident in more detail in "Function Description" >
"Object Dictionary" > "Structure of Module Ident".
The master has two opportunities to check the node structure.
Using object 0xF050, the master can read the structure of the local bus node. SI0
supplies the number of inserted I/O modules and the remaining subindices
supply the Module Ident's of the individual I/O modules. The master can read
these and compare them to a set list.
Alternatively, the master can write the number of expected I/O modules in SI0
from object 0xF030 and finally write the expected Module Ident's in the remaining
subindices from object 0xF030. In case of a difference, the write access is denied
by the fieldbus coupler using the SDO Abort Code 0x8000020.
