Workshop PG5
FUPLA programming
4.5 Write your first FUPLA program
Open the file:
At the beginning of this chapter (4), we made a new file called: "Blink with output".
We will write our first code in this file.
GOAL:
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 2) or normal run (NormalRun signal Input I 1). The pump must not run if
there is a emergency stop (Emergency signal Input I 7).
As long as the pump is running a signal lamp will blink. The lamp is connected to the
output 33 (PumpRun_Signal O 33)
Double-click on the file called: "Blink with output.fup" and the FUPLA editor will
open.
Prepare the symbols:
Before we start to write our program, we have to make a list of the symbols we are
planning to use. Enter the following symbols into the Symbol Editor: (Refer to page
3-13 if you need help on entering symbols)
Now the programming
begins:
The pump runs if the machine is in conditional run OR normal run:
Select the “OR” FBox from the family “Binary” and draw the first combination:
