I don't know if in your case you use GRAPH5/II. Try this tool: Converter from GRAPH5/II to S7 GRAPHFiles for conversion from GRAPH 5/II Best regards, Hristo Mihalev |

Hello aeiouauioe I think there's some confusion going on here, so allow me to explain a few things: SB's in S5 had a "Dr. PB and Mr. Sequencer"role. Mr. Sequencer: You woulduse S5 Graph to program (graphically) Sequencers and SB's would be used to store the sequencer logic. In this case you would need S5 Graph to "look" at the graphic Sequence program inside the SB and you would needUMENCHO's afforementioned S5 Graph converter to convert these to S7 (or reprogram them manually in Step 7) Dr. PB: You wouldprogram anSB just like you program a PB via "normal' Step5 languages (LAD/FBD/STL). In this case the S5 to S7 converter will convert the (LAD/FBD/STL)logic inside the SB just like any other S5 Block and create an S7 FC out of it. Question: What happens if you open SB 1or SB 2 with Step 5's (LAD/FBD/STL) Block editor? On the issue of the SB's NOT being called by your S5 program, be aware that Blocks can be called indirectly. This would typically be done by"DO FW xyz or DWxyz" command followed by a "JU (or JC) SB 0" (the 0 is a just a so called placeholder which is substituted in runtime by the variable number in the FW or DW of the "DO" command). I suggest youat least quickly check the Xref of your S5 program for calls to "SB 0"to see if this indirect Block call mechanims is used. Having said that the above, the "6ES5 095-8MA.." S5 95U contains SB2 as an integrated "default"Graph 5 related Sequencer Block (whether you use it or not, see the 95U manual for more) which can explain its existence in your program (it may have come from a PLC upload,this doesn't explain SB 1 though). I hope this helps |
