Hello Everybody, I take a look on every docs about AR_SEND and I only found 1 thread talking about the fact that AR_SEND block only works with S7-400 dating from 20/12/2006. Is there a possibility that this block works with new firmware of S7-300 CPU's ? In all new topics talking about AR_SEND there is no restrictions. Best regards Splitted from Data logging in CPU. |

Hello Nicolas Blocqueau I'm afraid to say that SFB37 "AR_SEND" is still missing from the operating system of even the latest 300 CPU's (see HERE for the latest instruction list). Since adownloadable FB "AR_SEND" doesNOT exist either, you will have to resortto using the clever trick as described by Decin THIS thread to "emulate" AR_SEND behaviour in a 300. |
