Error code A00C, 8304 in MB_REDCL block

Hi,

8304 is no connection between plc and the communication partner.

chcek connection status in NetPro.

Ip addresses and the port numbers, CP address in NetPro and in the hardware.

Thanks,

Yes, in net pro connection status changes from established to closed and so on. IP address and port settings are ok. Error code 8304 is followed by error A00C which means the received byte count does not match the number of registers/bits. How to rectify this error ?

Hello,

check if you have BYTES count as WORDs needed, so if you expect receive 2 WORDs, you must have min. 4 BYTES in your struct/array.
