    PROGRAMMING LOGIC USING TEXT SCRIPTS


    What is a Script?
    A Script is a file with orders that once loaded on to the EGW1, is interpreted and executed.

    Operations performed by a Script: The Script describes what operations should be executed by the device, for example:

  • Math Operations
  • Binary Logic Operations
  • Date and Time Operations
  • Working with Timers
  • Read Analog variables
  • Records of Variables
  • Digital I/O Read/Write
  • Sending and receiving SMS
  • Interpretation of data from the serial port
