➢ The mode is applied to the input variables to generate the following result as the output
variable:
o Or: Result = ON if at least one input is ON.
o And: Result = ON if all linked inputs are ON.
o Flip flop: The flip flop function (also called a holding circuit) operates according to the
following formula:
▪ Result = permanently ON if at least one of the inputs I1, I3, I5, I7, I9 has been set to
ON (set holding circuit), even if the input drops out again afterwards (set pulse).
▪ Result = permanently OFF if at least one of the inputs I2, I4, I6, I8, I10 has been set to
ON (delete holding circuit). This delete command is dominant. Therefore switch-on is
not possible when a delete input is ON (reset pulse).
o Exclusive or (also termed XOR)
Result = ON if an uneven number of input variables are set to ON.
Example with two input variables: The result is ON if one of the two input variables is
set to ON. If both are set to ON or OFF, the result is OFF.
Another example with five input variables: The input variables 1, 2 and 3 are set to ON,
4 and 5 to OFF. The result is ON because three input variables (= uneven number) are
set to OFF.
➢ Unused inputs are ignored in all modes.
