Hi,

i've red some topic about this issue, but with no solution, so i have to ask again.

I am using CP443-1 6gk7 443-1ex20-0xe0 v2.1 with CPU414-4H and i need to establish communication via TCP/IP protocol by ethernet to external program on PC. For communication i use AG_SEND FC15. Parameters are ok, correctly setted, but still i getting error code 80b0 - The module does not recognize the data record.

Any advice is welcome.

Thanks for support.

I ment that i am using communication function of CP_300 family so i tried to change FC15 to FC5 from CP_400 family, now it has no error code, but i dont think that the communication is executed, because CPU has different error about adress. -> After deleting old FC15 change of Symbolic table and full program reload error changed - 7000 with blinking 80b0 ...

Problem probubly solved - solution better read help. Issue - FC5 AG_SEND for CP_400 has limited length of sended data <=240 bytes. For sending longer data <8192 need to be used FC50 AG_LSEND.

Also check HW config of used CP's and used comm. function!

Thanks for support.
