Is it possible to connect a HMI panel such as the TP177B PN/DP as a Profibus slave to an APACS PFM? |

Hello Bucs, I'm sorry but the HMI Panel acts as a master and communicates with S7-PLCs with S7-communication. So, it's not possible to connect this HMI as a slave. Best regards. H-H |

Any other Siemens product that could provide this functionality? |

Hello Bucs, I have only one idea that may not look so perfect. You can buy thecheapestS7-PLC that has 2 interfaces like 315-2DP or 313C-2DP. Configure the PLC as a slave for the PFM and use the other interface for the HMI panel. In this case you will be just able transfer 244I/O byte. Maybe if you sacrifice yourHMI updaterate you can transfer multiple of 244 I/O bytes with some effort in programming. Best regards. H-H |
