Hello, SFC can beboth: - the Sequential (or Static?) Function Chart editor and - a SystemFunction. I think (and I 'm not shure!) the SFC-editor can only be used with a S7-400 CPU (and maybe a CPU 18). I looked in the S7-300 Instruction List(Page 132 /133). There is no SFB 35 listed for the S7-300 CPUs. Looks to my like you try to transfer a PLC-program from S7-400 to S7-300. |

As far as I know both exist, S7 Graph and SFC. I heared from SFC always together with CFC. I think S7 Graph was desined for S7 and SFC for PCS7 Have a look on Chapter 1.1 in this manual: SFC for S7 6.1 (in my eyes the name should be "SFC for PCS7 V6.1") for more information on SFC |

Thanks for the link. I have no experience in PCS7 and since it is posted under S7-300, I guess it is not about PCS7. Moreover, in my very limited knowledge about PCS7, it uses S7-400 as Automation System and since CPU here mentioned is S7-300, it should be a standard S7 system. |
