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
program 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
Configuration".

Overview of the system PLC program structure
The settings in the "Task Configuration" and "Library Manager"
areas should not be changed.
7.2.2
prMAIN main program
The most important program of the system program is the main program
"prMAIN". The main program is used to call all other programs and function
blocks. On delivery, power supply activation and the interfaces to the CNC,
the axes and the HMI are already programmed ready for turn-on.
The main program is also used to call system program extensions. We rec‐
ommend that appropriate subroutines are created which can be called from
the main program "prMAIN".
The following figure shows the data structure provided and potential exten‐
sions. The user should not delete the system programs and system function
blocks called in prMAIN.
