4.3.1 [1] AND operation
Type Function
Type Function
I1
b input value 1
O1
b O1 = AND (I1 I2 I3 I4)
I2
b input value 2
O2
b
negated output O2 =
1O
I3
b input value 3
P1
I4
b input value 4
P2
Description:
The inputs are AND-combined with one another. The inputs of the instruction are the assigned
signal sources. Output is TRUE if all inputs are TRUE. As soon as one input is FALSE, the output
will be FALSE. Via the output buffer, the output signal is globally available.
Note:
Unused inputs must be set to "6 - TRUE". For example, I3 and I4 must be set to "6 - TRUE" if
inputs I1 and I2 are to be combined by the AND operation.

4.3.2 [2] OR operation
Type Function
Type Function
I1
b input value 1
O1
b O1 = OR (I1 I2 I3 I4)
I2
b input value 2
O2
b
negated output O2 =
1O
I3
b input value 3
P1
I4
b input value 4
P2
Description:
The inputs are OR-combined with one another. The inputs of the instruction are the assigned
signal sources. Output is logic TRUE if at least one input is TRUE. If all inputs are FALSE, the
output will be FALSE. Via the output buffer, the output signal is globally available.
Note:
Unused inputs must be set to "7 - FALSE" (factory setting). For example, I3 and I4 must be set
to "7 - FALSE" if inputs I1 and I2 are to be combined by the OR operation.
