  • Page 10 Section 1-1 Features Introduction This manual describes the installation and operation of NT20M and NT2000M Programmable Terminals (PTs). Both models can come with or without touch panels. Programmable Terminals have three main functions: 1) monitoring operating conditions, 2) directing on-site personnel, and 3) input- ting data.

  • Page 44: Numeric Displays

    Section 4-5 Numeric Displays Numeric Displays A numeral table is stored in the PT, and you can display numeric values from the table at programmed positions on a screen. In addition, the values in the table can be transferred from the host so that they are renewed each time a new value is transferred.

  • Page 45: Character Strings

    Section 4-6 Character Strings Character Strings This function displays variable character strings on the screen. These char- acter strings can be changed with transmissions from the host. A character string memory table is stored in the PT. By changing, from the host, the memory table values corresponding to the display position, you can update the characters displayed.

  • Page 46: Bar Graphs

    Section 4-8 Lamps Bar Graphs If the numeric values that you want to make into a bar graph have been input into the numeral table in advance, then that graph can be displayed simply by designating the screen on which the graph is registered.
