7.5 Write your first IL Program
Open the file:
At the beginning of this chapter (7.0) we made a new file called : "Oilpump.src"
We will write our first code into this file.
GOAL:
Lets start with a simple binary combination.
We will turn on a pump ( Oilpump signal O 32 ) if the oil level becomes too
high ( OilHigh signal input I 0 ) and if the machine is in conditional Run (
Cond_Run signal input I 1 ) or normal run ( NormalRun signal input I 2 ). But
the pump must not run if there is an emergency stop ( Emergency signal input I
7 )
This is what the program would look like in LADDER:
Double-click on the file called: "Oilpump.src" and Sedit will open.
Before we start to write our program, we have to make a list of the symbols we
are planing to use. Enter the following symbols into the Symbol Editor:
