Did you select "Slavemode" for the DP-Port of Slave CPU? Please show us the diagnostic buffer. |

Check your hardware IO, and check FC1 and FC2 send and recieve bit length. It should have same legth. |

Hello sogal there are no restrictions and 315-2 PN/DP should work just as well as an intelligentDP Slave as the older 315-2 DP did. Questions: Are both stations in the same project and did you use the "Configured Stations" to set up the 315 as the DP Slave (e.g. as per THIS example) OR did you use a GSD file based configuration of the 315 as a DP Slave? If the latter is the case I wonder if you used the correct GSD file for the 315-2 PN/DP (please check and grab the correct from HERE if need be). I hoep this helps and if not please upload your S7 project here for evaluation. |
