4.3.3 Parameters of digital output modules
Overview
The configurable digital output modules use a subset of the parameters and ranges of values
listed in the table below, depending on the functionality. For information on subsets
"supported" by specific digital modules, refer to the section dealing with the relevant module
beginning with section 4.7.
The defaults apply if you have not set any parameters in
STEP 7

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.
