3.6.7 Second circuit program
Up to this point, you have successfully created your first
circuit and assigned it a name and, if desired, a password. In
this section we will show you how to modify existing circuit
programs and how to use the special functions.
Using this second circuit program, we will show you how to:
• Add a block to an existing circuit program.
• Select a block for a special function.
• Assign parameters.
Modifying circuits
We shall use the first circuit program as a basis for the
second, with som
e slight modifications.
First of all take a look at the circuit diagra
m for the second
circuit program:
You already know the first part of
the circuit. S1 and S2 switch a
relay, which is to be used to
switch on the load E1, and to
switch off the load with a delay of
12 minutes.
