The Basic Instruction Set
Evaluating a rising signal pulse
Ladder Diagram
Relay M0 is only switched on for the duration of a single
program cycle
Evaluating a falling signal pulse
Ladder Diagram
If X0 is off (0) and M235 is on (1) relay M374 is switched on for the
duration of a single program cycle.
With the exception of the pulse trigger characteristic the functions of the LDP, LDF, ANDP,
ANDF, ORP and ORF instructions are identical to those of the LD, AND and OR instructions.
This means that you can use pulse-trigger operations in your programs in exactly the same
way as the conventional versions.
