Example of an SDB 100

Introduction
Module identifier
5-4
Using a programmable controller containing an SDB 100, modules whose
parameters can be assigned can be parameterized each time a switch is made
from STOP to RUN.
During startup, the CPU performs a bus identification procedure and enters
the module identifier(s).
When the SDB 100 is transferred to the module, the CPU first checks to de-
termine whether the module identifier entered for the respective slot matches
the module identifier stored in the SDB 100 for this slot. The parameters are
not transferred until this check is performed successfully.
The module identifier classifies the installed module with respect to its ad-
dress in the I/O address area of the CPU.
Example:
The SM 338 has the module identifier 05ED
00000101 11101101
