• 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.
