2.1.13- Scheduler
The Scheduler allows to control a digital output point (exclusively virtual point) as function of the current day
and time. MCP 4 includes a timekeeper circuit with back-up battery to avoid the date and time loss when
disconnecting the main power supply. The transition from standard to daylight saving time is made
automatically by MCP 4.
MCP 4 includes a complete weekly Scheduler: it allows to specify, for each day of the week, in which time
slots the specified output must be activated and which are not.
Such programming is repeated identical for all the weeks of the year. The virtual point controlled by the
Scheduler must then eventually reported to the desired physical outputs, in combination with other points if
required.
The Scheduler integrated in MCP 4 allows the control of 16 different points (“zones”) each one with 8 time
slots (8 ON-OFF intervals) for each day of the week. The resolution of the Scheduler is 1 minute.
The Scheduler will be activated by the following directive:
SCHEDULER
n (
Vx
)
where:
n
is the Scheduler number (“zone”) and it must be in the range 1 to 16
Vx
is the controlled virtual point
I the points to be controlled are more than one, more directives must be added as in the following example.
SCHEDULER
1 (
V100
)
SCHEDULER
2 (
V101
)
SCHEDULER
3 (
V102
)
Unlike CLOCK equation which will be described later, where the specified times are set in the user program
and then the change these ones requires reprogramming of MCP 4, the Scheduler here described allows
easy setting from any supervision program or through the WEB server (optional) integrated in MCP 4. For
details on entering and modification of schedules, refer to the specific documentation.
The following figure shows an example of a page that can be developed for the management of the
Scheduler.
