Hello Ste39, Thank you for the link - this is very interesting, how to transfer larger amount of data - but still it is S7 connection (BSend/BReceive via CPs). Thank you. Regards, Jiri |

Hello Ste39, I can see FDL in the table for my CP. Please see attached picture. There is no particular information about number of connections, I hope that it is possible to have them more than 1 connections.. Thank you. Regards, Jiri |

Hello, I don't think that you can to have more than 1 connection with 1 CP eg. 1 CP=1 connection. You should find the method of moving the data block to have two separate blocks eg. the first 236 bytes and another (I do not know what is missing to you) and call the first one then the other, and back to the first, you can surely, but I do not have ever done. |
