I'm setting up a communication with an Ethernet s7-300 cpu. But when I connect cpu313c-2dp to cp343-1 ethernet module, communication is being established, but sina_pos block gives DPRD_DAT error. Do I need a block for communication between the Ethernet module and the CPU? Can you send a sample document or program? ------------------------------------------------------------------------------------------ Split from CP343-1 SFC14 ,SFC15.

If you use a CP you must use PNIO_SEND and PNIO_RECV. And SINA_XX Blocks are designed for the Onboard Interfaces of the PLC, CP are not supported. Regards Christoph
