•
OR
function block. Each block has up to six inputs and two outputs where one is
inverted.
•
PULSETIMER
function block can be used, for example, for pulse extensions or
limiting of operation of outputs, settable pulse time.
•
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, after a power interruption, the flip-flop resets or
returns to the state it had before the power interruption.
RESET
input has priority.
•
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, after a power interruption, the flip-flop resets or
returns to the state it had before the power interruption. The
SET
input has
priority.
•
TIMERSET
function has pick-up and drop-out delayed outputs related to the
input signal. The timer has a settable time delay.
•
XOR
function block. Each block has two outputs where one is inverted.
15.6.1
AND function block AND
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.
