Instructions:
Use the "SFC-Chart".TARGETSEQ and "SFC-Chart".TARGETSTEP connections in order to switch from one SFC sequencer and continue the sequence in another SFC sequencer.
"SFC-Chart".TARGETSEQ is the number of the sequencer to which you wish to switch. You can find the number in the properties dialog box for the sequencer under "Edit > Sequencer Properties".
  Fig. 01
"SFC-Chart".TARGETSTEP is the number of the step to which you wish to switch. You can find the number in the step properties. Right-click the target step to open the properties dialog box.
  Fig. 02
In the target step dialog box you can check the sequencer and step which were active most recently with "SFC-Chart".LASTSEQ or "SFC-Chart".LASTSTEP in order to set different target steps, for example.
During configuration, use the assignments TARGETSTEP and TARGETSEQ when processing the step, for example, as a way of indicating where you wish to switch to.
  Fig. 03
Note:
The TARGETSEQ and TARGETSTEP parameters are not used to "jump" to another sequencer. The parameters enable you to process this sequencer later on by defining the step (TARGET STEP) from which you wish to start processing the sequencer. The sequencer is activated in accordance with the operating status logic of the SFC, e.g. by executing the corresponding command, not by setting TARGETSEQ.
You can find further information in the Online Help for the SFC under "SFC - Sequential Function Chart > Runtime controls in the PLC > Processing an SFC".
