Function operation:
The STP function is used to execute sequence programs. Changing the signal at the exe input from 0 to 1 activates the active output, which is active until the condition of transition to the next step is met, i.e. signal 1 appears on the end_cond input. When the active signal is switched off, the output next is switched on for one program cycle.
If the exe input goes from 0 to 1 with the end_cond signal active, the active output will not be activated and the next output will change state for high for one program cycle.
The active state of the special marker M1011 resets the active and next outputs of all STP blocks in the program. Be sure to change marker M1011 to inactive before running the sequence program.
