3.9 Other performance recommendations
Here you can find some general recommendations that enable faster program
processing of the controller.
Recommendation
Note the following recommendations for programming S7-1200/1500 controllers in
order to achieve a high performance:
LAD/FBD: Disable "generate ENO" for blocks. This avoids tests at runtime.
STL: Do not use registers since address and data registers are only emulated
for compatibility reasons by S7-1500.
Note You will find further information in the following entry:
How do you disable the ENO enable output of an instruction?
