Handling Precautions
In a timer code event, an On Time or Off Time setting that is the same as
or exceeds the segment time is invalid.
Note, however, that when there is a G.SOAK wait at the end of a segment
or an END mode at the end of a program, an On Time or Off Time setting
that is the same as the segment time is valid.
● When the event is an event off
Such event items on the programming map are skipped and not displayed.
● When the event is an instrument event
Such event items on the programming map are skipped and not displayed.
