MEP, MEF
Outline
MEP and MEF commands are instructions that change the operation results to pulses so that device numbers do not
have to be specified.
1) MEP
have to be specified.
1) MEP
The operation results up to the MEP instruction become conductive when the driving contacts turn ON from OFF.
The use of MEP instructions simplifies the process of changing driving contacts to pulses when multiple contact
points connect in a series.

points connect in a series.
2) MEF
The operation results up to the MEF instruction become conductive when the driving contacts turn OFF from ON.
The use of MEF instructions simplifies the process of changing driving contacts to pulses when multiple contact
points connect in a series.
