The parameters for the SM 322; DO 4 x 24V/10mA are set with STEP 7 .
You must implement the settings in CPU STOP mode. During transfer from
the PG to the S7-300, the parameters set in this way are stored in the CPU
and then transferred by the CPU to the digital module.
Alternatively, you can also change several parameters in the user program
with SFCs 55 to 57 (see /235/).
The parameters for the 2 parameterization alternatives are subdivided into:
Static parameters
Dynamic parameters
Table 2-8 shows the characteristics of static and dynamic parameters.

The digital output features default settings for diagnostics, substitute values,
etc. (see Table 2-10).
These default settings are applicable when the digital module has not been
parameterized with STEP 7 .
The characteristics of the SM 322; DO 4 x 24V/10mA can be parameterized
with the following parameter blocks:
