Bluetooth Advantage
1. Replace the string wire cable : Connection with wireless Bluetooth may replace the string wire cable.
2. Unifies the Bluetooth and the Internet technology. Uses CPU handling ability which Bluetooth offers, increases multi-function for the equipment, such as build-in WEB human interface stage.
3. Industry Access Point. Through access point connects several Bluetooth equipment with the traditional wired network, for instance IP network (ex : Ethernet) or industry scene fieldbus network. (ex : Controlnet and Profibus...etc. )
4. Wireless sensor and starter. Use Bluetooth to come to relate the closest equipment with the physical system regulation (sensor, starter and the simple analogy/several IO equipment) connects the supervisory system.

Replace Serial Cable

At present many industrial equipment all use the traditional serial interface (ex.RS232, RS422 or RS485) to connect the disposing tool or programming tool. Those tools specially need to redeploy or to program when the equipment with it connection, usually all operates on the standard computer, and generally uses some independent method or the equipment special-purpose correspondence reached an agreement comes and the equipment carries on the connection. These factors all cause this field to become a Bluetooth very good opportunity.

Chart 1.

Had demonstrated the PC type programming tool which connects PLC using the string serial (link) cable.
Replaces the string serial cable with the Bluetooth to have two methods : One is outside industrial equipment sets at sequence port connected to Bluetooth adapter, another is the equipment electron partial interior connected in sets at the Bluetooth adapter.
The Bluetooth adapter may the analogy sequence port, and uses the RFCOMM agreement (to support Serial Port Profile) in the air transmit data. The computer may use the PC card or additional equipment supports the Bluetooth.

The Bluetooth also may set at the TCP/IP equipment and the WEB server more advanced industrial equipment domain in the support replace the string cable.

Chart 2.

had demonstrated the Bluetooth adapter replaces the basic structure of serail cable.

Bluetooth and Internet Technology Combination.

MCU is embedded with RF circuit, unceasingly transmit the dynamic condition and control variable information by normative Modbus agreement to computer. (Ref.chart 3).

Chart 3

Add a Bluetooth adapter to this equipment (out built or inbuilt). Bluetooth adapter through Modbus agreement and valve correspondence. The WEB/WAP page was provided by inbuilt WEB/WAP server., and draws support from Modbus to reach an agreement compiles, uses in to show and the revision dynamic data.
This structure drawing shows in chart 4 :

Chart 4

To see from the chart 4, except Modbus, the Bluetooth adapter can use other industry agreements and the device control system communication as well. It may use the WAP over Bluetooth mobile come to visit inbuilt WAP user interface. WAP over the Bluetooth standard is fixed "the route" function to be one part of the mobile capability. This causes the local WAP page is allowed to have hyperlink to WAN Center.

The industry access point

Using the wireless correspondence in the industry environment will be a process. To request industrial equipment must be able to use the Bluetooth function and to be connected with the existing wirednetwork, for instance IP network (ex : Eithernet) or industry scene fieldbus network (ex : Controlnet and Profibus and so on).

Chart 5.

The WEB interface built into equipment is through. (AP, as in chart 5 1). AP likes "the telephone converter", connects each valve. Through the WEB interface built into AP, could display all connection with Bluetooth equipment.

The user chooses one of the equipment, and establishes LAP with this equipment (Lan AccessProfile) to connect, and then AP starts to operate a router function. At the same time, the user through Bluetooth ...all equipment based on WEB HMI (like in chart 5 2). The second example : AP uses modem, GSM, GPRS or UMTS technology to have a AP function. (like in chart 6).

Chart 6

Many varied of fieldbus in today´s industry, has the standard, also has some special for merchants.The under is showing Bluetooth function equipment. Fieldbus Access Point connected in the original wired network using the scene. (like chart7).

Chart 7

Bluetooth equipment transmits the data to the access point through bluetooth special-purpose transmission agreement (chart 7 1). The datal is transformed into the form which support filedbus, and transmits to one of the filedbus that send the request instruction in the equipment.

In chart 7 -2, the bluetooth equipment also simultaneously be as the Internet equipment in built WEB HMI and access point with carring on data receiving and dispatching the data getting equipment.
Chart 8 showing the basic equipment of Fieldbus Access Point

Chart 8

Here´s data transmission agreement can use to call the Bluetooth on the L2CAP or RFCOMM to stack. .

Wireless sensor and starter

The wireless sensor and the starter extremely fit to the application field of migrating industrial equipment.

This application needs a plan of replacing power supply (for instance to use battery or other power sources). It can support a complete wireless plan. The bluetooth is proper to be applied to support low power module, but when developing this plan must to pay much attention on request.

Chart 9

The first example (chart 9) the control system (PLC) has contained some simple I/O equipment and two wisdoms sensor/starter (here is single return route controller), I/O equipment is through the standard wired I/O fieldbus connection. Even if the Bluetooth connection temporarily severs, the single return route controller still be able to execution.

Chart 10

The second example (chart 10) the control system I/O equipment is connects through the bluetooth. This kind of plan is requested much careful, in order to ensure the communication is stable.

I have a question:

2.4GHz Bluetooth 2.0V Low Working Voltage Data Module
