n If input RESET is set to "1" when the call is issued to SFB 32 then the cycle switch
changes to the step that you have specified as a number at input DSP.
n When this module is called for the first time the RESET input must be set to "1".
n If the cycle switch has reached the last step and the processing time defined for this
step has expired, then outputs Q and EOD will be set and SFB 32 will remain at the
last step until the RESET input is set to "1".
n The SFB 32 is only active in operating modes STARTUP and RUN.
n If SFB 32 must be initialized after a restart it must be called from OB 100 with RESET
= "1".
The remaining processing time DCC in the current step will only be
decremented if the respective event bit EVENTi is set.
Special conditions apply if parameter DRUM_EN is set to "1":
– timer-controlled cycle switching, if EVENTi = "1" with DSP = I =
LST_STEP.
– event-controlled cycle switching by means of event bits EVENTi,
when DTBP = "0".
In addition it is possible to advance the cycle switch at any time (even if
DRUM_EN = "1") by means of the JOG input.
