Addressing
symbols &
using arrays:
By the way:
If you work with symbols, you can add constants or other symbols to your
symbol. Like this you can define a basis address and then refer to an element in
perspective to this basis element.
Example:
An output card PCD2.A400 with 8 outputs is placed into the slot with the start
address 80. We then want to set the third output (output 82):
Definition:
We can simply write: SET OutputMotor1+2 in our program.
A more elegant way is to reserve an array of 8 outputs:
In the program we then set the output 82 like this:
SET OutputMotor1[2]
Auto complete
symbols:
If you use long symbol names your program will become easier to read. On the
other hand it will be annoying if you have to re-enter the long symbol name
each time you use it in the program. Therefore you can simply enter the first
letters of a symbol, and then lookup all the symbols which fit the first letters
by using the keys “CTRL and SPACEBAR”:
Example:
CTRL + SPACE
ENTER
