3.7.7 Second circuit program
Up to this point, you have successfully created your first circuit program, assigned it a name,
and optionally a program password. In this section you will learn how to modify existing circuit
programs and how to use the special functions.
Using this second circuit program, you will learn how to perform the following tasks:
Add a block to an existing circuit program
Select a block for a special function
Assign parameters
Modifying circuits
ou will use the first circuit program as a basis for the second, with some slight modifications.
First of all take a look at the circuit diagram for the second circuit program:
This is the circuit program layout in IDEC SmartRelay:
ou can see the OR block and the output relay 1 that you used in the first circuit program.
The only difference is the new off-delay block.
