16. With ‘LAD, STL, and FBD – Program S7 Blocks’, you now have an editor that allows you to

edit your STEP7 program accordingly. To this end, OB35 has already been opened with the

first network.

To generate your first operations, you have to highlight the first network. Now you can write your

fist STEP7 program.

In STEP 7, individual programs are usually subdivided into networks. You open a new network

by clicking on the network symbol.

Note: Comments on program documentation are separated from the program commands by the

character sequence“//“.
