S-Bus

S-Bus (Smart-BUS) is a protocol based on RS485 connection Topology for intelligent buildings. S-bus is the developed protocol using 64 bits long code, 32 bits as short code, targeting to become the Asian and African Standard protocol as administered by the Smart-Group Association,

Protocol Name Synonyms:

"Smart-BUS" can be called S-BUS, S.BUS, SBus, or sbuspro

Also another S-Bus known as (Saia-Burgess Bus) is a dedicated protocol for reading process data from devices provided by the Saia-Burgess company.

Wire transmission

Twisted pair of data using signaling speed of 9600 bit/s. flexible Bus power with 8-32 V DC, and 25 mA, Polarization critical. Can install up to 250 Devices in each bus group with 254 subnets, linking with network bridges, up to 65280 device per network, Maximum bus length is 1600 m.

Technology:

"Smart-BUS" is a patented Protocol (Patent No: 201110123081.0) Based on "Advanced RS485" 64 Bits Communication. This 2-Way Smart-BUS Communication Protocol was Designed Mainly for Home Automation Industry and thus many call it today "SmartHome-BUS" or Simply "S-BUS".

The S-BUS Engine Drive Many Hardware Devices, Command, Monitor and Control them simultaneously in smooth and confirmed 2-Way Communication ability using Simple 4-Core Twist Pair Data Cable that is widely available in the market.

The Smart-BUS has Multi Edge technology to Easily Communicate with multi Nodes; Wirelessly via the "W-BUS" in what is called the "S-Mesh" Environment. Also It can Communicate with FTP/UDP/TCP Via what is Called the "S-Net" Environment. This "Smart-BUS" Multi-Edge Environment and the Core System technology are Called collectively: the "Smart-Cloud"

Topology:

Using Smart-BUS Technology, installer can connect up to 250 Devices on One Cable that can reach in length up to *(1600 meters). and up to 64000 devices on a single RSIP Network Bridge. where over 16,000,000 can be monitored and controlled in one Network of 250 Bridges.

Meaning that: If installer Link Several BUS Loops together using Network bridges, then up to 65280 devices per network Bridge can be smoothly linked and up to 254 Loops like wise can be Networked together as one Body.

Smart-BUS has very flexible connectivity: It uses Mainly Daisy Chain, it can be either an Open or closed Loop/Ring, Can Work in star Topology wiring, or Even Grid or Mesh.

SMART-BUS Design and Idea:

The smart-BUS or as it was First Called SBUSPro (smart BUS Professional). Has been created as vision with clear targets to become the world’s new Standard of Automation Industry:

1. To have Open Protocol System
2. To Have a System that can Communicate with Thousands of Nodes
3. To Have a system that communicates easily over long Distances
4. To have a system that is Green and do not consume lots of energy
5. To have Smart system with 2-way communication, Monitoring and control.
6. To create a consortium of many manufacturers that can create solutions as PnP

When designing the system, it was also mandatory to understand Installation complexity and protection and well as Tolerance needs:

1. Current Fluctuations in different Countries and Dirty Electricity
2. Variable Voltage and Frequency
3. Cable quality and Disturbances that require Big Operational Voltage Range
4. Overload Protection
5. Over Heat Protection
6. Reverse Polarity Protection
7. LV Port Protection
8. Short Circuit Protection
9. Mixed Wiring Topologies
10. Bothe New and Retrofit Installations
11. Easy Expandability
12. Simple Configuration and Upgrade
13. Modular compact size System
14. Multifunctional Devices for Flexible Stock Usage

Learning from The Best:

When Creating the smart Bus, Many Other Manufacturers and Giant Technologies where the source of inspiration, and the trigger of such system that is Almost Bullet proof.

As well known to many:

• Internet is the Best in Bandwidth and Number of Nodes xxx.xxx.xxx.xxx (But internet Need Network Devices every 150 Meters in Average)
• KNX is the Best in Open Protocol Concept and consortium Concept (But it is not Fully open)
• RS-485 is best in Distances (BUT require special Topology)

Smart-BUS is the mix of best features from all:

S-BUS: as an Advanced RS-485 with flexible Topology and Super Long Distances that Embraces Internet Subnets Ability to connect More than 64000 Devices in one single Net, yet it is based on KNX Open concept.

Industry Giants that we learned from, took their Best and Avoided their Mistakes became accordingly added value Contributors to our Design:

• Delta Controls, (Modularity flexibility)
• Clipsal C-BUS (Simplicity in Programing and Hand Pairing)
• Dynalite (Scripting Multi functionality actions)
• Bosch (Voltage Tolerance)
• HAI (Security and Logic)
• Crestron (IR and Integration)
• Nuvo (Simplicity in Audio Distribution)
• ELAN (Media and Special Sensors)
• Control4 (Retro fit Solutions and Mesh Network)

Issues avoided During Smart-BUS Design:

• End of Loop Terminators (Echo, and daisy chain)
• Voltage Drop or Over Power Issues (Loss of communication, or burning of com Boards)
• Central Wiring (Start Topology Issues)
• Load Limitation Issues (Low Load handling ability of Retro)
• Wifi and LAN Network Issues (Freezes, Security, Pro installers)
• Short circuit Issues (Losses)
• Stocking of Multiple Devices for Multiple Function (Different Device for Different Volt and Function)
• Non Uniform Shapes of Fixtures (Wall Agony)
• Professional Programmers and Scripters issues (Limitations and Costs)
• Special cables (Cost and Availability)

Other Issues that are also considered while designing the system:

1. Working in Dark Locations (No Power yet)
2. Working in Harsh Temperatures (Hot/Cold)
3. Some Installers are Color Blind
4. Sometimes cables are mixed with CCS, CCA or Other
5. Sometimes communication and control cables must pass with Electrical Runs.
6. Sometimes Installers connect loads then measure after its late
7. Many installers go Cheap or easy and do not install protection fuses and breakers

Smart-BUS when designed, it had all the above accounted for as the base and the standard for its topology, field devices, configuration and protocols.

S-BUS Operating Voltage:

The S-BUS Engine can work at wide Voltage DC Range between 8-32Volts. And is considered Green as it consumes between 20-32mA per device during operation. The S-BUS uses 4 Wires (2-Pairs): one Pair for Data Communication and the other for Power. The Smart-BUS has Also Several Lines of protection like: Reverse Polarity Protection, Short Circuit protection, Overload Protection, Overheat protection, and other..

Open Protocol:

Smart-BUS Patented Protocol is also an Open Protocol provided to Professional Developers and Integrators Free of Charge. (Any Registered Organization / Developer Can Easily and directly get the complete Protocol documents that they need after filling and Signing the proper Quality Network Paperwork). The Inventors Mr. Firas Mazloum Mr. Mendel Lin, and Mr. Turath Mazloum has Made Sure to patent the Protocol and BUS technology To Make Sure that it remains Open to Serve Humanity and Environment.

Smart-BUS Enabled Devices and solutions:

Several Home Automation and Building Control Devices are widely available worldwide today, and provided through several Developers and Manufacturers.
