4.3.2 Parameters of the Digital Output Modules

The parameterized digital output modules use a subset of the parameters and

ranges of values listed in the table below, depending on the functionality. Refer to

the section on the relevant digital module, starting from Section 4.16, to find out

which subset it is capable of using.

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 support from HWCONFIG.
