Introduction
The properties of analog modules may differ. The module properties can be programmed.
Programming tools
You program analog modules in STEP 7 . Always program the module while the CPU is in
STOP mode.
After you defined all parameters, download these from your PG to the CPU. The CPU
transfers the parameters to the relevant analog modules at the STOP → RUN transition.
Also, position the measuring range modules of the module as required.
Static and dynamic parameters
Parameters are organized by static and dynamic properties.
Set the static parameters while the CPU is in STOP, as described earlier.
You can also modify dynamic parameters in the active user program using SFCs. However,
the parameters set in
STEP 7 will be applied again after a RUN → STOP, STOP → RUN
transition of the CPU.
Parameters configurable using CPU
operating state
static PG (STEP 7 HW CONFIG) STOP
PG (STEP 7 HW CONFIG) STOP dynamic
SFC 55 in the user program RUN

Parameters of analog input modules
For information on parameters supported by specific analog modules, refer to the chapter
dealing with the relevant module.
The defaults apply if you have not set any parameters in STEP 7.
