From version 4.2.0
Generic Driver is a communication driver available with Reliance 4. It is designed for the data exchange (through a serial port or Ethernet) between Reliance and devices for which a native driver or OPC/DDE server is not available. In the future, Generic driver should be used instead of External Communicator. The communication with a connected device is realized through special tags defined within the Generic device (in the Device Manager). In comparison with External Communicator, Generic Driver is more deeply integrated into a visualization project and it is easier to use. In addition, it is likely to be further improved along with other native communication drivers.
Note: Generic Driver will be functional with the license for External Communicator. External Communicator will not be further developed and maintained.
