10.10.8 Using the SNVT_tod_event
On LOYTEC devices supporting CEA-709 networks, the SNVT_tod_event can be used in a
schedule for implementing the next-state feature. The parts of this network variable are:
Current state: This is the currently scheduled occupancy state.
Next state: This is the next, future occupancy state in the schedule.
Time to next state: This part reflects the time in minutes until the next state
becomes active.
To Use a SNVT_tod_event
1.
Create a SNVT_tod_event in the data point configuration.
2.
Add the SNVT_tod_event to the scheduled data points of a scheduler as described in
Section 10.10.4.
3.
All three parts of the SNVT_tod_event are scheduled.
10.10.9 Schedule Configuration Data
It is important to note that the configuration of the scheduler and calendar objects consists
of two parts:
One is the point setup, meaning the number of calendar patterns, number of scheduler
objects, and which points are controlled by which scheduler. This information is part of the
data point setup of the project, similar to the definition of local and remote network objects.
It is always in effect when the project is downloaded and it will have an influence on the
static interface of a CEA-709 device.
The other part is the dates entered in calendar patterns and the actual schedule of each
scheduler (when the scheduler should output which value preset as well as the definition of
the value presets themselves). This information is usually changed during the runtime of the
device, that is, it is considered dynamic data, similar to the current value of a network
variable or server object (this data is in fact the current value of such objects). Therefore,
this data is not reset with every project download, since the user wants to keep the current
values if possible. Only if the scheduler setup itself changed, the device will not be able to
take over the current settings, since they do no longer apply.
