      I am looking for a paid or free course online for LabVIEW instrument control that covers topic like  communication protocols, RS232. GPIB etc. Can anyone suggest a good one. Thank You.

      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 project is now available on GitHub: https://github.com/rfporter/Modbus-Master

      I wanted to cross post metux's discovery here asap, and have a separate discussion.
      Metux's original post:
      The recent Linux driver package introduces a CRITICAL security vulnerability:
      It adds additional yum/zypper repos, but explicitly disabling package signing and using unencrypted HTTP transport. That way, it's pretty trivial to completely takeover the affected systems, by injecting malicious packages.
      CERT and BSI are already notified.

      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
