5.1 Introduction to the software
The 907 PC 331 programming software is used for all the AC31 basic units.
This software runs under DOS and also in DOS boxes of Windows
®
(3.1, 95 or NT). In
Windows 95 and NT there are slight restrictions, e.g. printing via network does not work
correctly.
The software allows you to create, send, test and print user programs as well as initialize, start
and stop the basic unit.
There are three programming languages:
- LD: is a graphical language based on the symbols of contact diagrams. It was adapted for
combinational processing and offers the basic symbols and automation function blocks
such as contacts, timers, counters.
- FBD: is a graphical language of function blocks which allows complex procedure
programming by combining existing library functions.
- IL: is an instruction list program which is intended primarily for programmers who already
have considerable experience of automation.
