Table of Contents

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

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 should be reset or return to the state

before the interruption, after a power interruption. Set input has priority.

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 should be reset or return to the state

before the interruption, after a power interruption. Reset input has priority.
