It is possible to activate the O.P.O. mode by:
- serial link
- by keyboard
- automatically at the end of a program execution.
It is possible to exit from O.P.O. mode:
- manually by
- serial link
- keyboard
- logic input (RUN/HOLD selection)
- automatically by Clock function.
Clock calendar
This option allows to obtain an automatic start of the selected
program even if the plant is unmanned.
In run time mode it is possible to select the program to start and
to set the time and the day of the automatic start.
In run time mode it is also possible to verify the actual time and
day of the instrument.
The actual time and day is programmed in configuration mode
(group 6).
In configuration mode is also possible to set the start condition.
NOTES:
A) If the program selection is made by logic inputs, three
different situations may occur:
A.1) the selected program exists, the starting program will
be the program selected by logic input;
A.2) the selected program is the program 0 or a program
higher 99, the starting program will be the program
selected by “Pr.St” [rb.05] parameter;
A.3) the selected program does not exist but it is between
program 1 and 99, no program will start.
B) If a logic input used for RUN/HOLD selection is programmed
and the selection is related with the input status, two
different situation may occurs:
B.1) when the start time has due and the logic input is in
HOLD condition, the program execution does not start;
B.2) When the program assigned to the clock start is
selected, and a RUN command is generated, the
program does not start until the programmed time is
reached.
