Below you will find a section from a STEP7 STL program.
The configured start address of the inputs and outputs of the 2PULSE is 256. Configured
with a short control interface.
You use this part of the program to start the process. To do this, memory marker M30.0 must
be set. Set up the off-delay in memory word MW32.
