Example programs
The following program illustrates the initialization of the serial RS232 interface
in the INIT: section and the cyclic reading and writing of data in the EVENT:.
section. The process is timer-controlled:
REM The program initializes the serial interface
REM in the Init: section.
REM In the Event: section data is exchanged between
REM the interfaces 1 & 2 of the RS module.
REM The interfaces are tested with this program.
REM For this connect the interfaces with each other
REM befor starting the program.
