Programming/flow diagrams
Below you will find a section from a STEP 7 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 filling process. To do this, memory marker
M30.0 must be set.
The pulse duration in this example is 5000 ms.
