Hello, Check this sample: DP link between CPU 315-2DP (slave) and S7-400 (master) with STEP 7 V5.3
Finally also check the concise description( by our well-experienced expert in Communication and Networks "fritz". Best regards Hamid Hosseini |

Hello, You should allso have a look at the Training modules. D6 - PROFIBUS DP with Master CPU 315-2 DP / Slave CPU 315-2DPAnd more usefull documents with example projects. Regards, Marcjan |
Problem solved? |

Hi Hosseini. I made a simple sample program for 2 plc s cpu 300 and i need your opinion about sample attach. I need to exchange data beetwen master and slave and I'm sure i made mistakes because it s not working in plcsim.Can u help me and change a sample (in LAD language) to be okay? Thank s Best regards George

Dear ChessMaster,
You mean ,for example, to trigger input signals in Master side instead of triggering output signal in slave side.That is possible but does not look natural .Also, I am not sure you can use simulator for SFC14, SFC15 as it may generate error(808x-->System error with external DP interface module).
There is other options when using CPs for PROFIBUS that support for example FDL, S7 Connection.It is possible to simulate communication between 2 CPUs with S7 connection with some system function blocks. check it here: How do you simulate communication between two CPU modules?
