Configurable logic blocks
14.3.1
Introduction
A number of logic blocks and timers are available for the user to adapt the
configuration to the specific application needs.
•
OR
function block.
•
INVERTER
function blocks that inverts the input signal.
•
PULSETIMER
function block can be used, for example, for pulse extensions or
limiting of operation of outputs, settable pulse time.
•
GATE
function block is used for whether or not a signal should be able to pass
from the input to the output.
•
XOR
function block.
•
LOOPDELAY
function block used to delay the output signal one execution cycle.
•
TIMERSET
function has pick-up and drop-out delayed outputs related to the
input signal. The timer has a settable time delay.
•
AND
function block.
•
SRMEMORY
function block is a flip-flop that can set or reset an output from two
inputs respectively. Each block has two outputs where one is inverted. The
memory setting controls if the block's output should reset or return to the state it
was, after a power interruption.
•
RSMEMORY
function block is a flip-flop that can reset or set an output from two
inputs respectively. Each block has two outputs where one is inverted. The
memory setting controls if the block's output should reset or return to the state it
was, after a power interruption.
RESET
input has priority.
