Mr - Master Reset - Eaton easyE4 series Manual

6.1.7.8 MR - Master reset
General
easyE4 base devices provide 32 master reset function
blocks MR01 to MR32.
These function blocks can be used to set the markers
and all device outputs to a state of 0.
Operating principle
Depending on the operating mode set, it is possible to reset either the outputs only, the
markers only or both.
To ensure that all data ranges are reliably cleared, the master
reset function block must be the last function block executed in
your program. Otherwise subsequent function blocks may
overwrite the data ranges again.
