In the menu "Programmable Logic Control" you can enable or disable the logic control of
the MLT analyzer, of the analyzer module or of the digital outputs by a corresponding
program. So, you can decide for instance if some calibration results should be sent to a
certain analyzer output. If you want to realize a program, you have to change to the
submenu "Program" (line "Programming..."). If you want to control the output status you
have to change to the submenu "PLC Outputs" (line "Results...").

Note:
The PLC is only able to work with signals of the MLT analyzer or analyzer module selected!
It is not possible to work with auxiliary modules or external undefined input signals!
