      View File Plasmionique Modbus Master
      This package contains the Plasmionique Modbus Master library for LabVIEW.
      It supports RTU, ASCII and TCP modes with the following function codes:
      0x01 - Read Coils
      0x02 - Read Discrete Inputs
      0x03 - Read Holding Registers
      0x04 - Read Input Registers
      0x05 - Write Single Coil
      0x06 - Write Single Register
      0x07 - Read Exception Status
      0x0F - Write Multiple Coils
      0x10 - Write Multiple Registers
      0x16 - Mask Write Register
      0x17 - Read/Write Multiple Registers
      0x2B/0x0E - Read Device Identification
      Other features include:
      - Sharing a COM port across multiple Modbus sessions using VISA locks (10 second timeout).
      - Sharing a Modbus session across multiple communication loops.
      - TCP transaction ID handling to ensure that requests and responses are matched up correctly in case responses are received out of order.
      - Modbus Comm Tester, available through the "Tools->Plasmionique" menu, for testing communication with a slave device without writing any code. 
      - Detailed help document available through the "Help->Plasmionique" menu.
      Examples are included in "<LabVIEW>\examples\Plasmionique\MB Master\":
      MB_Master Comm Tester.vi: Demonstrates usage of API to open/close connection and communicate with a Modbus slave device. MB_Master Multiple Sessions.vi: Demonstrates usage of API to open concurrent Modbus sessions. MB_Master Simple Serial.vi: Demonstrates polling of a single input register over serial line. Download a copy of the user guide here: MB_Master - User Guide.pdf
      Note that Version 1.3.4 of this library has been certified compatible with LabVIEW and has been released on the LabVIEW Tools Network: http://sine.ni.com/nips/cds/view/p/lang/en/nid/214230
      The most recent version of this library will always be released on LAVA first before going through NI's certification process.

      This is a DSC module question: has anybody here experience with building standalone executables which include shared variables bound to DSC modbus i/o servers? I have an issue with deployment, possibly related to licensing. I posted on the dark side, but haven't got feedback yet.

      TIA, Enrico

      Hi,
      How i can to send the data through modbus TCP/IP (behavior of a PLC) and receive the data in other client computer with ( station , I/O ADRESSE)
      can you send me an example for this operation please.
       
      Thank you for your help.
