## Description

The **Scenario Scheduler** is a Home Controller with instructions called scenarios. These scenarios are managed by receiving **CEN Frames** from command modules or from software to activate, deactivate, enable and disable each scenario.

CEN Frames can be sent on the SCS BUS using SCS Devices (as a normal SCS Command) or using an Open Web Net / SCS Gateway.

The Scenario Scheduler reads these frames on the bus, analyzes them, manages scenarios.

The Scenario Scheduler works also as an Ethernet Gateway¹. It monitors all the SCS Frames traveling in the SCS bus, and all the Open Web Net Frames arriving from IP socket connections. The received SCS Frames are processed and routed according to the CEN source address and the key pressure information.

CEN Frames can be used for integration between My Home System and 3rd party Systems.

Installing My Home Commands in the system, configured as CEN, it's possible to forward the information of pressure of a Command to a 3rd party System using a Scenario Scheduler as Ethernet Gateway. This information can be used to control functions of other System.

*¹ MH200 doesn't manage this function*

A SCS Command configured in modality CEN generates CEN messages when one of its push button is pressed.

This schema helps to understand the meaning of the new functions available with the evolved CEN and CEN PLUS:

## Example

The following schema helps to understand how the Scenario Scheduler translates into Open Web Net frames the actions done on the systems, when a push button of SCS Command configured with M = CEN is pressed or a Software sends CEN Message to the System.

## CEN PLUS Example

The following schema helps to understand how the Scenario Scheduler translates into Open Web Net frames the actions done on the systems, when a push button of SCS Command configured with M = CEN PLUS is pressed or a Software sends CEN Message to the System.

### Example Sequences

When the push button n° 1 of SCS Command 1 is pressed, kept pressed, then released an Open Web Net Client reads the following sequence of OWN Frames:

| Event Connection | Time         | OWN Frame         | Action            |
|:-----------------|:-------------|:------------------|:------------------|
| Client ← Server  | 14:44:00:051 | `*25*22#1*21##`   | Pressure          |
| Client ← Server  | 14:44:00:551 | `*25*23#1*21##`   | Extended Pressure |
| Client ← Server  | 14:44:01:082 | `*25*23#1*21##`   | Extended Pressure |
| Client ← Server  | 14:44:01:238 | `*25*24#1*21##`   | Release           |

When the push button n° 2 of SCS Command 2 is pressed and released after 0.5 seconds an Open Web Net Client reads the following sequence of OWN Frames:

| Event Connection | Time         | OWN Frame           | Action   |
|:-----------------|:-------------|:--------------------|:---------|
| Client ← Server  | 14:42:29:354 | `*25*22#2*22047##`  | Pressure |
| Client ← Server  | 14:42:29:557 | `*25*24#2*22047##`  | Release  |

When the push button n° 3, address 3, of SCS Command is pressed and released in less than 0.5 seconds an Open Web Net Client reads the following sequence of OWN Frames:

| Event Connection | Time         | OWN Frame       | Action   |
|:-----------------|:-------------|:----------------|:---------|
| Client ← Server  | 14:43:22:604 | `*25*21#3*20##` | Pressure |

### Virtual Command Examples

When an OWN Client sends a Virtual Short Pressure of Button=31, WHERE = 1, each Client with an Event Connection opened reads the following OWN Frame:

| Action Connection | Time         | OWN Frame         | Action                |
|:------------------|:-------------|:------------------|:----------------------|
| Client → Server   | 16:11:07:528 | `*25*21#31*21##`  | Virtual short pressure|

| Event Connection | Time         | OWN Frame         | Action                |
|:-----------------|:-------------|:------------------|:----------------------|
| Client ← Server  | 16:11:07:044 | `*25*21#31*21##`  | Virtual Short Pressure|

When an OWN Client sends a Virtual Start of extended pressure of Button=3, WHERE = 2010, each Client with an Event Connection opened reads the following OWN Frame:

| Action Connection | Time         | OWN Frame           | Action                              |
|:------------------|:-------------|:--------------------|:------------------------------------|
| Client → Server   | 16:11:09:041 | `*25*22#3*22010##`  | Start of a virtual extended pressure|

| Event Connection | Time         | OWN Frame           | Action                              |
|:-----------------|:-------------|:--------------------|:------------------------------------|
| Client ← Server  | 16:11:09:062 | `*25*22#3*22010##`  | Start of a virtual extended pressure|

When an OWN Client sends a Virtual extended pressure of Button=0, WHERE = 0, each Client with an Event Connection opened reads the following OWN Frame:

| Action Connection | Time         | OWN Frame       | Action                   |
|:------------------|:-------------|:----------------|:-------------------------|
| Client → Server   | 16:11:21:926 | `*15*23#0*20##` | Virtual extended pressure|

| Event Connection | Time         | OWN Frame       | Action                   |
|:-----------------|:-------------|:----------------|:-------------------------|
| Client ← Server  | 16:11:21:942 | `*15*23#0*20##` | Virtual extended pressure|

When an OWN Client sends a Virtual Release after extended pressure of Button=10, WHERE = 101, each Client with an Event Connection opened reads the following OWN Frame:

| Action Connection | Time         | OWN Frame          | Action                             |
|:------------------|:-------------|:-------------------|:-----------------------------------|
| Client → Server   | 16:15:57:142 | `*15*24#10*2101##` | End of a virtual extended pressure |

| Event Connection | Time         | OWN Frame          | Action                             |
|:-----------------|:-------------|:-------------------|:-----------------------------------|
| Client ← Server  | 16:15:57:163 | `*15*24#10*2101##` | End of a virtual extended pressure |

## General Information About Devices Configured in CEN Mode

### Advanced CEN Configuration

• CEN devices configured with Advanced Virtual Configuration don't use an address on the SCS BUS

• CEN devices configured with Basic Virtual Configuration use an address on the SCS BUS

• CEN devices configured with Physical Jumper use an address on the SCS BUS

**Advanced Virtual Configuration**

Address → WHERE → Object (TiMH200N)

Button n → WHAT → Action (Button) (TiMH200N)

### CEN PLUS Configuration

• CEN Plus device can be configured only with Advanced Virtual Configuration and don't use an address on the BUS

**Advanced Virtual Configuration**

CEN Number → WHERE → Pushbutton (TiMH200N)

Button n → WHAT parameter → Object (TiMH200N)

## Important Note

CEN frames are always delivered via SCS to a Scenario Scheduler. Without a Scenario Scheduler connected on the SCS BUS, the other gateways are not able to read from the SCS System the CEN frames.

For example, if a command is configured as CEN, a F453 can forward OWN CEN Frames to a Client only if an MH200N is on the BUS. Otherwise, when the pushbutton of a command is pressed, the F453 doesn't translate this information.
