6.2 PLC System Program Structure
6.2.1 Overview
The PLC
system program has a clear structure. The most essential elements
are the following:
1. The "_OEM" folder is provided for the programs and function blocks of the
machine manufacturer. This folder is empty on delivery.
2. The "_System" folder is reserved for interfaces, programs and data struc‐
tures of the system program.
3. The global variables of the system are defined (declared) in the "_Sys‐
tem_Variables" list. These global variables can be used in any program
and/or function block. More global variables are declared in the
"MT_MTXmicro_Tech" library.
4. The "I_O_VARIABLES" list contains all digital inputs and outputs of the
MTX micro (see also: chapter "Configuration Instructions").
5. All programs are called from the "_prMAIN" main program. The main pro‐
gram is called and processed cyclically (every 20 ms).
6. The "Library Manager" contains the system libraries.
7. The chronological run of the PLC program is controlled in the "Task Con‐
figuration".
