Hello, I am sending data from a siemens 319-3PN/DP Plc with a Additional Cp343-1 card from the Plc to a remote BNR pc. I have configured 2 tcp send/recv connections in netpro.The PC is the master in the connections. 1 receiving 182 bytes and sending 8 bytes every 50ms. The other connection every 250ms send 252bytes and receives 0 bytes. Both connections are running however after a couple of minutes i get the error 80B0 The module does not recognize the data record. At that point the send telegrams stop for 2/3seconds and then the communication goes again. I only notice this on the send side. receiving data never has this problem. I have updated teh cp card to newest firmware. i have replaced it. but it didnt help. It seems to have something to do with the load. becasue if disable 3 out of the 4 ag communication blocks the time before he same eror comes increases. Does anybody hav an idea? at siemens they also dont know what coould be the problem. Only thing they say it can be the cpu or programming error.
