3.6.4 Second Program
We will use the second program to show you the following:
How to insert a block in an existing program.
How to select a block for a special function.
How to enter parameters.
Changing circuits
In order to produce the second program, we have to modify
the first one slightly.
Let’s begin by looking at the circuit diagram for the second
program:

You already know the first part of
the circuit. Switches S1 and S2 op-
erate a relay. This relay switches on
consumer E1 and switches it off af-
ter a delay of 12 minutes.
