Dear Maarten, The error-message is coming because the receiving unit have not yet get the data with the AG_RECV from the CP443-5, so for the new one that comes there is no space.... and that is giving the message that you are refering to. So the cycletime of the receiving CPU have to be shorter then the sending one, you could also get the bit DONE (without errors)of the AG_SEND. See also the example of the FDL communication. How do you program the communication blocks FC5 and FC6? It could also be that you didn't load Netpro into the CPU's, or that the CPUs are not in one project and that the configuration is not right between the CPUs. |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
