Causes and Fixes

  1. 1

    Press the Help key (i) or soft key to display the syntax requirements for the current PLC variable data type.

  2. 2

    Verify the data type of the PLC variable you are modifying (BYTE, WORD, DWORD, INT, REAL, etc.) in the PLC status display.

  3. 3

    Re-enter the value using correct syntax: decimal numbers without prefix, hexadecimal with 'H' suffix (e.g., 1A3H), or binary with 'B' suffix (e.g., 10110101B).

  4. 4

    Ensure the value is within the valid range for the data type (e.g., 0-255 for BYTE, -32768 to 32767 for INT).
