4.3.1 Parameters of the Digital Input Modules
The parameterized digital input modules use a subset of the parameters and
ranges of values listed in the table below, depending on functionality. Refer to the
section on a particular digital module, starting from Section 4.7, to find out which
subset it is capable of using.
Don’t forget that some digital modules have different time delays after parameter
assignment.
The default settings apply if you have not performed parameter assignment in
STEP 7.

1)
If you use the module in ER-1/ER-2, you must set this parameter to “No” because the interrupt lines are
not available in ER-1/ER-2.
2)
Only in the CC (central controller) is It possible to start up the digital modules with the default settings and
without HWCONFIG support.
