In a PLC program, the two functions M14 and M15 are to be programmed as

follows:

M−function Target function Programming in the PLC program

M15 Lift tool Output "tool down" (O_ToolDown) = 0

Wait for "tool up" (I_ToolUp) = 1

M14 Lower tool Output "tool down" (O_ToolDown) = 1

Wait for "tool up" (I_ToolDown) = 1

M30 Program end −−

A program in the language "sequence control" consists of the basic elements

"step", "transition" and "branch". In the sequential function chart, elements

can be added via the right mouse button.

The program "Training1" consists of an initialisation block with two steps

and one transition.
