Hello, Are you using a CP343-1 Lean, then it is not possible. Because the Lean card can not be a Profinet IO Controller. See the following link: What differences are there between the Industrial Ethernet CPs of SIMATIC S7-300? Best regards, Wizard |

hi emilhumm, CP343-1 lean can´t work as IO-Controller, only as IO-Device. see the technical data: You need a CP343-1 6GK7343-1EX30-0XE0hope this helps, regards, |

Hi, for you question exists a FAQ - you only need FC11/FC12 once per CP343-1. How do you program communication blocks FC11 and FC12 for the PROFINET IO controller?Regards, Towome |

Hello, Perhaps these links might help: How do you program communication blocks FC11 and FC12 for the PROFINET IO controller? - You need 1 call of both blocks. - You need the amount of bytes to be mapped in Datablocks. You communicate through CP. Best regards, Wizard |

hi, no, you won´t. The CP343-1 has an own subordinate IO-system that needs to be read-out with the functions PNIO_SEND/PNIO_RCV. You can see it when you establish an IO-System on an internal interface(PN or PB). You can assign the address twice one on the internal system and one in the PNIO-System from the CP343-1. Whit addressing Ix.x and/or Qx.x you accessing the process-image of the IO-system of the internal interface. thats why you need to use this blocks like it is described in the FAQ: How do you program communication blocks FC11 and FC12 for the PROFINET IO controller?hope this helps, regards, |

SO do I need to make a DB with an array of 528 byte? Why does it need so much? |
