i!-Schedule

Introduction

i!-Schedule is an application that allows you to schedule NetLinx events directly from a touch panel

connected to a NetLinx control system. i!-Schedule provides a user interface to schedule up to 240

NetLinx events to run on a repeating or non-repeating basis. i!-Schedule also provides a scheduling

engine that triggers each event at the appropriate time and reschedule repeating events.

Two scheduling modules are available with i!-Schedule.

 i!-ScheduleEngineMod is the scheduling engine module only. This module has no user

interface and can be used for fixed events that do not need to be edited by the user. Use

this module if you do not want a user interface for scheduling.

 i!-ScheduleMod includes the functionality of the engine module and provides a user

interface where the user can edit the scheduling of events. Use this module if you want a

user interface for scheduling. You do not need to include the i!-ScheduleEngineMod if

you use this module.

Using i!-Schedule

i!-Schedule

Using i!-Schedule

Little work is required to add i!-Schedule to your existing NetLinx code. i!-Schedule is

implemented as a NetLinx module so you need to add the module definition and all it’s parameters

to your code. You must also define the NetLinx events you would like to schedule.

In order to use i!-Schedule, you will need to program and define a series of events in the NetLinx

control system. The key to the scheduling engine is the virtual device, vdvSchEvents. You must

support the events you want scheduled using this virtual device.

Think of the virtual device, vdvSchEvents, as a touch panel. Normally, you would write your

NetLinx program to respond to certain push channel from a touch panel; i!-Schedule is exactly the

same. Let’s say you want the user to be able to schedule when the outdoor lights turn on and when

they turn off. Imagine you have two touch panel buttons that do these functions. You would write

code that responds to the pushes; turning the lights on and then off. (Let’s use relays for lighting

control to simplify the example):

BUTTON_EVENT[TP,1] (* Outdoor Lights On *)

{

PUSH:

{

ON[RELAY,1]

}

BUTTON_EVENT[TP,2] (* Outdoor Lights Off *)

{

PUSH:

{

OFF[RELAY,1]

}

To schedule these events using i!-Schedule, we write the same code substituting the touch panel

device for our scheduling virtual device:

BUTTON_EVENT[vdvSchEvents,1] (* Outdoor Lights On *)

{

PUSH:

{

ON[RELAY,1]

}

BUTTON_EVENT[vdvSchEvents,2] (* Outdoor Lights Off *)

{

PUSH:

{

OFF[RELAY,1]

}

When the scheduling engine detects that the user has programmed the lights on event to run at a

certain time and that schedule time has occurred, i!-Schedule will "push" the button on the virtual

device just like a user pushes a button on a touch panel. There is now only one thing left to do: tell

the user which events are which.

In order to expose an event for scheduling via i!-Schedule, you need to support the programming

for the event (as we have just seen) tell i!-Schedule what that event is. i!-Schedule allows a user to

scroll through a list of events and edit the time which it runs. In order to associate an item in the list

Using i!-Schedule

4i!-Schedule

with a button/channel number, you must tell i!-Schedule what each channel you have programmed

can do.

To specify the name of an event, you need to send a command to the scheduling virtual device

describing the name of a given channel code. To specify the names of the commands in the above

example, you would add some code like this:

DATA_EVENT[vdvSchEvents]

{

ONLINE:

{

(* Setup events *)

(* Outdoor Lights On *)

SEND_COMMAND vdvSchEvents,"'SET NAME-1,Outdoor Lights Off '"

(* Outdoor Lights Off *)

SEND_COMMAND vdvSchEvents,"'SET NAME-2,Outdoor Lights Off'"

}

Once i!-Scheduling receives these commands, it will show the user the two events in the main event

list, sorted in alphabetical order, and allow the user to schedule these events. Whenever the user

schedules the "Outdoor Lights On" event to run at a certain time and that time occurs, the

scheduling engine will push button one and your code can turn the lights on.

Each event can be programmed to occur on a repeating or non-repeating basis running at a single

time per day. Additionally, each event can have a start and end time. Events do not have end dates

so they can only span a 24-hour period; however, that 24-hour period can span 2 dates by specifying

an end time less than a start time. For instance, if a user schedules an event to start at sunset and end

at sunrise, i!-Schedule will start the event at sunset of the scheduled day and stop the event at

sunrise of the following day.

In addition to specifying the name of an event, you can also program the date and time when the

event should occur. The scheduled virtual device supports a variety of commands to set and query

the values of the names, dates and times for each event. See the Send_Commands section on

page 12 for more details.

Dynamic Events

So far, i!-Schedule has handled simple fixed events where each event provides a single function and

can be scheduled only once for each day. Some scheduling applications require dynamic events

where the user can add and delete events on the fly. i!-Schedule has a provision to handle this case.

Let's look at the programming side of i!-Schedule for a moment. For every event that needs to be

scheduled, your program must contain a BUTTON_EVENT to handle the push and/or release of that

event. To provide dynamic events, you must provide dynamic BUTTON_EVENTS.

Let's say you want to schedule a new event using i!-Schedule while the program is running. This

seems easy, you simply add the send command to name the new event:

SEND_COMMAND vdvSchEvents,"'SET NAME-14,My New Event'"

The name "My new Event" appears in the event list, the user schedules it to occur at 5:00 on

Saturdays and everything is fine. Now Saturday 5:00 rolls around, and the scheduling engine

pushes button 14 for this event to occur. Since you did not re-compile and download your program

after the user scheduled the event, you would have had to add code for button event 14 prior to the

user scheduling the event! So the problem is: how do you program for an unknown number of

events that has not been scheduled? Additionally, since you did not define these events up front,

Using i!-Schedule

i!-Schedule

how is the distinction made between event 14 and the next event, 15 (they don't do the same thing

right?). One word: Event Parameters.

Event parameters provide a way to allow dynamic events to be added and deleted during run-time.

The Send_Command to the scheduling virtual device allows you to add and delete events while

i!-Schedule is running. Parameters will allow you to add additional information to each event to be

stored by i!-Schedule and recalled at the time the event is fired.

Let's take a simple example: a VCR record timer. Now let's make it a bit more complicated: How

about a VCR record timer for 5 VCRs. Now, to program this in NetLinx is pretty easy, if you know

the VCR number and the channel number the user whishes to record. Consider this code:

BUTTON_EVENT[dcVCRRecordEvents] (* VCR Recording *)

{

PUSH:

{

(* Assume we are able to obtain the VCR Number and the Channel Number *)

(* And we store them in nVCRNumber and nChannelNumber *)

Switch (nVCRNumber)

{

Case 1: dvVCRDev = dvVCR1

Case 2: dvVCRDev = dvVCR2

Case 3: dvVCRDev = dvVCR3

Case 4: dvVCRDev = dvVCR4

Case 5: dvVCRDev = dvVCR5

}

Send_Command dvVCRDev,"'CH',ITOA(nChannelNumber)"

Send_Command dvVCRDev,"'SP',8" (* Record *)

}

RELEASE:

{

Switch (nVCRNumber)

{

Case 1: dvVCRDev = dvVCR1

Case 2: dvVCRDev = dvVCR2

Case 3: dvVCRDev = dvVCR3

Case 4: dvVCRDev = dvVCR4

Case 5: dvVCRDev = dvVCR5

}

Send_Command dvVCRDev,"'SP',2" (* Stop *)

}

Easy, right? If we have the VCR number and Channel number, we can easily write a BUTTON_EVENT

handler for any number of buttons to start recording a certain channel on any number of VCR's for

any channel number. Therefore, the VCR number and the Channel number will need to be event

parameters.

Now, i!-Schedule is written to be a universal scheduling engine which means it has no idea that you

are interested in a VCR and Channel number. If i!-Schedule were written to understand these

parameters, then it would not be very useful for automatically dialing a phone number, since the

phone number could not be stored in either the VCR number location or the Channel number

location. And, it would be confusing to the user to say the least! To solve this problem, i!-Schedule

can support 8 number or value parameters and 8 string parameters per event. You may use these

parameters in any way you see fit.

To implement a parameter for a given event, you will need to collect the information, such as the

VCR number and Channel number, from the user and tell i!-Schedule to store these values along

with the event. In order to integrate the editing of the event and the editing of the parameters, each

Using i!-Schedule

6i!-Schedule

event has a Parameters page and Parameter Text associated with it. When the user edits a given user

and the event has a Parameter Page associated with it, a button labeled "Parameters" appears on the

editing page. If the user presses it, i!-Schedule generates a PAGE-<Parameter Page> command to

the touch panel. Optionally, if the Parameter Text option is set, the button displays this text instead

of the default "Parameters".

Now, this is where your programming comes into play. The user has now been flipped to the

Parameter Page where they expect to event parameters. You must implement the code to allow the

user to enter the parameters. For our example, we would implement some BUTTON_EVENT handlers

that allow the user to select from 1 of 5 VCR's and select a channel number.

Once you have gathered all the information needed to select what and where to record, you need to

tell the i!-Schedule module to store the parameters for you. For VCR numbers and Channel

numbers, it would be appropriate to use our value parameters to store this information. Use the

Value Parameter number 1 to store the VCR number and Value Parameter number 2 to store the

channel number. In practice, your page will probably have an OK and Cancel button. The Cancel

would simply return them to the scheduling edit page while the OK button would return them to the

scheduling edit page and update the parameters. You could send the new parameters values to

i!-Schedule as the user selects them, but there would be no way to "undo" them should they decide

to cancel. With that in mind, we would update i!-Schedule with the new parameters value on an OK

button handler like this:

BUTTON_EVENT[Tp,11] (* OK *)

{

PUSH:

{

(* VCR Number *)

SEND_COMMAND vdvSchEvents,"'SET VPARAM-14,1,',ITOA(nVCRNumberFromUser)"

(* Channel Number *)

SEND_COMMAND vdvSchEvents,"'SET VPARAM-14,2,',ITOA(nChannelNumberFromUser)"

}

Now, you do not need to remember which VCR number or Channel number was selected for this

event, i!-Schedule does that for you. To complete our code, we need to retrieve the parameters from

i!-Schedule when the event is triggered. i!-Schedule posts the string parameters, strings and value

parameters as levels prior to firing the event. When button event 14 is fired by

i!-Schedule, the VCR number and Channel number will be waiting on levels 1 and 2 to use. Add

this code:

DEFINE_VARIABLE

Volatile Integer nVCRNumberParam

Volatile Integer nChannelNumberParam

DEFINE_START

Create_Level vdvSchEvents,1,nVCRNumberParam

Create_Level vdvSchEvents,2,nChannelNumberParam

BUTTON_EVENT[dcVCRRecordEvents] (* VCR Recording *)

{

PUSH:

{

Switch (nVCRNumberParam)

{

Case 1: dvVCRDev = dvVCR1
