Siemens S7-300/400PLC Bluetooth communication suite manuals

    Bluetooth is a short-range wireless communication technologies, working in 2.4 GHz of the ISM band, the band Green free band of the genus, use the band the radio resource management departments to apply for license. Bluetooth has adopted a frequency hopping spread spectrum in the way, have good shielding, entered industrial control areas, more and more applications in industrial automation, distributed data acquisition, intelligent transport, electricity, hydraulics, and many other industries, industrial control interface implemented as RS232/RS485/RS422 transparent wireless transmission of signals.

       Siemens S7-300/400 series PLC Bluetooth communication suite FS-BT-MPI (FS is a registered trademark of the FourStar electronic FOURSTAR ), is a FourStar electronic research's industrial-grade Bluetooth MPI adapter, the implementation of the computer or a touch screen devices of RS232 port and USB port to Siemens S7-300/400 series PLC of  MPI estuary of Bluetooth wireless data communications, you can replace the traditional programming-communications interface adapter such as PC/MPI 、 USB/MPI 、 PC adapter etc., Do not need alteration original serial communication protocol and a variety of programming software, monitoring software, etc., do not need to settings, Plug and play is very convenient, especially suitable for use in the following occasions:

★ move or rotate serial communication between devices;

★ in the opposite, opposite the river or highway or railway or communication between devices;

★ other submarine cables all inconvenient for communication between the devices;

Product shape structure

      Each a FS-BT-MPI Composed by two , a connection to PC or touch screen interface of RS232 or USB, another connection S7-300/400 series PLC of MPI interface( RS485 interface), manufactured pairing set up with good right FS-BT-MPI enclosure stamped with the same sequence number .Can only be arranged on the second FS-BT-MPI only chain of communication between the ability to build, a different pair modules cannot be mixed, the parties on the impact of communication and distrust, just like the car's remote control keys can only be opened and its automobile the same.

       In order to tell and narrative convenience, we put the connection to the computer's FS-BT-MPI called “ Master  module ”, connections PLC' s  FS-BT-MPI called “From module.

 ”.

Antenna this product is labeled 2.4 GHz, 3dB antenna, to enhance communication in distance, optional 9dB 、 13dB 、 24dB , etc., high-gain antennas, communication distance may consult the antenna vendor.

           The following table is  FourStar electronic use different gain antenna measured distance from the Bluetooth communication:

Need to be explanatory is that data in a table is in open zone environment measured, in the Interior and the barrier of circumstances, the Bluetooth communication range has a larger decrease, the actual situation is complex, can only be measured according to a live environment.

Actual application should reduce barrier, maximize pairing two Bluetooth module mutual “can see” visible. as possible, do not use the product is installed on a metal cabinet avoid signal is shielded, free cable FS-BT-MPI tends to lead to be installed in the Cabinet, or with an antenna will antenna tends to lead to the Cabinet.

       Use the equipped with the product RS232 the main module for cable connection RS232 socket and computer RS232 receptacle, which had not been the main module, available power supply USB the main module for cable connection USB and of the computer USB , and use a computer USB ports of 5VDC power supply, for there is no such as like touch-screen USB port installations are now available for external power supply terminal voltage is on access9~ 40VDC any power to supply to the main module.

The master module of on USB outlet

       As a standard USB-B -oriented socket, equipped with the product are available from USB cable to connect to the computer's USB estuary, when the work of the main module from the computer's power supply in USB estuary supply, no need external power supply. The first time you USB mouth may prompt you to install the USB drivers, please click on the computer prompts you to install CD's USB driver USB converted to a serial port (com port), please refer to the CD of the USB driver installation notes document.

       The baud rate in the table is a locally attached serial baud rate, and MPI The baud rate for 187.5Kbps and 19.2Kbps, which is included with the PLC of MPI the baud rate to automatically adapt to port.

The required assurances communication software and the Lord, from the module settings to the same baud rate, change switch modules have to power the new settings will take effect.

FS-BT-MPI example

       Personal computer STEP7 programming software and S7-300/400  series PLC implementation of Bluetooth wireless communication, uploaded, downloaded program data, monitoring, PLC etc., Usage are as follows:

1、 FS-BT-MPI the master module and the baud rate from the module to switch to dial and STEP7 programming software “ settings PG/PC interface local area connection ” in the same baud rate, such as 19200bps or 38400bps 。

2、 The master module USB estuary connection to the computer's USB estuary, if this is the first use USB estuary will be prompted to install USB driver, install the driver after the USB port in the Windows of the Device Manager in the corresponding serial number, (com number)。

If you use RS232 estuary, the master module of RS232 estuary connection to the computer's RS232 estuary, when you need to connect the master module USB estuary to the computer's USB estuary to gain power, or in a separate add-in 9~ 40VDC DC power supply.

3、 From the module DB9M plug into PLC of MPI interface( RS485 interface)。If this is more than one S7-300/400PLC MPI of the network, you will be DB9M plug into the network band programming port bus connector.

Note: this product does not support connecting S7-300/400PLC of the PROFIBUS communication port.

4、 If the Bluetooth-slave module of unanimity within range of effective communication, FS-BT-MPI of link some blue indicator light will Flash become flashing on after the seconds that represents the master-slave module has established the Bluetooth communication links, you can have transparent data transfer, this State called“ built chain”.

5、Open STEP7 programming software, click main menu under “ option ” “ setting PG/PC interfaces ” entry, select “ PC adapter( MPI)”, After you click on the  “ Properties ” button ,shown in the following figure:

6、The MPI set communication parameters baud rate setting can be into 19.2Kbps or 187.5Kbps ,FS-BT-MPI automatically adapt to the MPI of the port's baud rate of the PLC, Other parameters to default values, look something like this:

7、Set the local connection of serial port and baud rate as shown in the following figure:

8、 Click “ identify ” button to return to the superior menu, and then click “ identify ” the button to return to main menu,

9、Online tests can be access nodes: click main menu interface as a button in the red circle, appear in the chart data in the Red wire frame, the online test to pass, at this point is set to complete, you can make online, uploading, downloading, monitoring, and so on.

       Go to this, the computer has already passed the Bluetooth wireless connection to the remote S7-300/400PLC , on the remote user can PLC conduct program data upload, download, monitoring the use of communication, and PC/MPI 、 USB/MPI 、 PC adapter etc cable exactly the same.

FS-BT-MPI can also be used in the third-party touch screen or other device and S7-300/400PLC of MPI connection, such as eView , Wei-lun, Kunlun State specific such as touch screen, see using the method of computing and PLC connections.
