Who know how can connect rs232 or rs485 device ?


  • Now want to use mango received the data . Devicehave connect the computer via rs232(serial).

    what protocol and data source will be choosen?


  • What protocol is the device you want to connect to? If you know that then you know what Protocol to use in Mango. There is also a general serial data source that you can use regex to parse values out of the serial stream. See the end of this thread to download the latest module.

  • I find the EQUIPMENT use RS232 communication and the TCPIP .SO what protocol will be choose for receiving data ?


  • You need to find out what protocol your device uses. RS232 or TCPIP are not protocols they are only methods of communication. You need to find documentation on your equipment that will tell you what protocol or language they speak.


  • yes.
    The equipment can output:-

    ASCII comma separated data with RS232, RS422 or RS485 levels.

    SDI-12 format data.

    Modbus ASCII or RTU data with RS232 or RS485 levels.

    But now the equipment directly the computer via serial port(rs232). what should I do ? whether use modbus serial is supported? if it not support it whether I must use modbus tcp/ip?

    Configuration
    Click on the MODBUS Page
    Mode: Choose between RTU and ASCII, in this case RTU.
    Address: Choose a MetPak Address number to be between 1 to 247.
    Data Bits: Choose 7 for Modbus ASCII and 8 for Modbus RTU.
    Stop Bits: Choose 1 for Even/Odd Parity or 2 for No Parity (None).
    Parity: Choose Even/Odd or None.
    Termination Char ASCII code: Choose between 0-255.
    Inter Char Timeout (ms): Choose between 500ms to 10000ms.
    Operation
    Select the COMMS Page
    Protocol: Select MODBUS
    Interface: Default is RS232. Select RS232 or RS4852W. RS232 will only
    allow a single point to point non multi drop network connection. RS485 2 wire will
    allow networking with up to 32 connected devices.
    Baud Rate: Default is 19200. Select required Baud rate (9600 or 19200
    supported).
    Node ID: Default is Q. Not used for MODBUS.
    Output Rate: Default is 1Hz. Set update rate for Data (0.25Hz
    to 1Hz).
    Message Mode: Default is CONT. Select POLL mode and equipment will
    only make and output a measurement (set by the output rate) on demand from the
    Modbus Master. In CONTinuous mode the MetPak continuously makes
    measurements set by output rate (0.25Hz to 1Hz) and only outputs a result when
    demanded from the Modbus Master.
    When required settings have been selected click on Save Settings to Device
    Click on Yes and OK.
    Power down the and apply power back to the MetPak to complete setting
    changes.
    Note: now that the unit is in MODBUS mode if any further changes need to be
    made use the SAFE MODE connection and method to re-establish communication
    with equipment

  • HI,
    I try to connect use modbus serial .but I setting COM1 (it is really COM1 port) and scan modbus node and it is not sucessful.in data point display " Point value may not be reliable ".
    I donot know how to setting make modbus serial can connect mango system. but I use hyperterminal it is very easy to connect COM1 port as show attahment.

    any idea?

    BR

  • Have not answer?


  • When I in Port find "dev/ttys0" and "dev/ttys1", When I choose "/dev/ttyS0", In "point locator test" test and display "There was a problem testing the locator. (com.serotonin.io.serial.SerialPortException: Port In Use: /dev/ttyS0)" ,when I choose "/dev/ttyS1", In "point locator test" test and display “Main equipment malfunction:1”,

    Any suggestion?
