In the attachment you find the FC5 and FC6 functions. The ID is 1, i think it's the same as the ID in the netpro configuration. AttachmentDoc1.zip (248 Downloads) |

Hi Frederik84, it's right, the ID is 1. Your Laddr is w#16#0100. This information you can find easily in NetPro --> block parameters
Please check the laddr parameter, I think there is the fault. |

What do you meen? The block parameter in netpro is W#16#0100 (LADDR). So in my program, this is the same parameter for FC5 and FC6. |

Hi Frederik Maybe I can help ..if you still have the problem On PLC side we use FC5 FC6 or FC50 FC60 ,we use a UDP connection On the Delphi side we use the UDP Indy components and this works very well One problem is using UDP where you get no confirmation of succecfull send , We did a loop back to check if the data arrived. Another problem is with the indy components , they are not compatible between versions, upgrading Delphi from say D7 to D2010 or to Delphi XE will mean that you have to remove the existing indy and re-install the new components Greetings Eric EDIT1 I just noticed that you are sending more than 240 byte ... See if you can reduce this to 240 AttachmentDelphi_S7.zip (281 Downloads) |
