SPECIAL INPUTS
These input symbols cannot be placed on the input units of the controller.
Digital constants
Constant level 1 (ON). Used to position the function inputs.
Constant level 0 (OFF). Used to position the function inputs.
In simulation and monitoring modes, these constants can be inverted by clicking on the symbol or by clicking (with the right-hand mouse button) on the symbol output or on the output connection.
Constant level 1 (ON) forced to the OFF state
Constant level 0 (OFF) forced to the ON state
Numerical constant (integer between -32768 and + 32767). Used to
set numerical values on the non-connected inputs of the following functions:
COMPARE IN ZONE, GAIN and TRIGGER
The value of the constant specified/modified in the parameters tab in the parameters box cannot be modified via the DISPLAY function. When the program is in the controller, the only parameter modification mechanisms which can be used to change the constant are the buttons on the front panel.
Other inputs
In edit mode, the symbols are displayed with the value OFF.
OFF | ON | Type |

SUMMERTIME: The output is in the OFF state for the whole of wintertime and changes to the ON state for the whole of summertime. |
