8.4 Conditionally interruptible program sections (DELAYFSTON, DELAYFSTOF)
Comments
; Blocks with N10xxx program level 1.
; Stop delay section starts.
; Interpretation of subprogram 2
; Ineffective, repeated start, 2nd level.
; Ineffective, end at another level.
; Stop delay section end at the same level.
; Stop delay section ends. From now, stops act
immediately.
Path traversing behavior
Stops immediately even in stop delay
section.
Does not stop (even short-term) until after
stop delay section.
Program is aborted because illegal program
commands have been used in stop delay
section.
Program is continued, an illegal action has
taken place in the stop delay section.
The program section (stop delay section)
enclosed by DELAYFSTON and
DELAYFSTOF could not be activated.
Every stop will take effect immediately in
the section and is not subject to a delay.
