Technical manual
When any one of 16 input signals (INPUT1 to INPUT16) has logical value 1, the
IND output signal will get logical value 1.
The function has a drop-off delay of 200 ms when all inputs are reset to provide a
steady signal.

Basic configurable logic blocks

The basic configurable logic blocks do not propagate the time stamp and quality of
signals (have no suffix QT at the end of their function name). A number of logic
blocks and timers are always available as basic for the user to adapt the
configuration to the specific application needs. The list below shows a summary of
the function blocks and their features.
These logic blocks are also available as part of an extension logic package with the
same number of instances.
• AND function block. The AND function is used to form general combinatory
expressions with boolean variables. The AND function block has up to four
inputs and two outputs. One of the outputs is inverted.
• GATE function block is used for whether or not a signal should be able to pass
from the input to the output.
• INVERTER function block that inverts the input signal to the output.
• LLD function block. Loop delay used to delay the output signal one execution
cycle.
