GLOBAL SYMBOLS<br />

Global symbols are know to all the files in the CPU.<br />

Make locak symbols<br />

global:<br />

If you want to use the same symbols in several files, then you have to move the<br />

symbols from the local list to the “GLOBAL” list (just mark some symbols in<br />

the list use the “Make Global” function (right mouse click)). Once a symbol is<br />

listed as “GLOBAL”, you can access it from any file within your project.<br />

Sharing data between two different PCD’s is more complicated than sharing<br />

information between files. You need some kind of network connection between<br />

the two PCD’s. This network connection can be designed in our network editor<br />

(to date we support: Sbus, Profibus DP, Profibus FMS and LON Networks).<br />

The “Network Editor” lists all the symbols in the “Network” list, and you can<br />

use them in your program in order to move data from one PCD to the other.<br />
