Logic Function Blocks
The Logic Function Blocks (FL) perform logical operations on the digital input
signals before their values are used in the control system.
The available logic function blocks are summarised below.
Table 30 Available Logic Operations.
The Logic Function Blocks can be interconnected to allow more complex logic
functions to be constructed from basic operators. For example connecting a digital
function block set to NOT to the output of a block that is set to AND will give the
logical NAND function.
And
Status = Signal1 AND Signal2 AND Signal3 AND Signal4
The And function has four digital inputs, Signal1, Signal2, Signal3, Signal4 and
one digital output, Status.
