Hi Karri_R, for a safety-related IO-Controller-IO-Device communication transfer areas with 6 and 12 bytes are needed, see "Safety-related IO-Controller-IO-Device communication - Limits for data transfer". You should also take care to write the parameter LADDR of SENDDP and RCVDP for a S7-300 in hexadecimal format. Kind regards |

The communication is now working after adding 6 bytes for both directions. Thank you Stefan Arcularius! |
