I would like to establish a communication between my laptop (WinXP) and a CPU 314 with MPI. I have an old PC Adapter V5.1. I use COM1 with a USB/RS-232 converter trademark ARP DATACON After that, I have an homemade cable RS-232 until the PC Adapter. Baudrate is everywhere set to 19200 (On the Adapter, in PG/PC interface,in the COM1) . I have set PG/PC interface to PC Adapter(MPI) and local connection on COM1. The led "Power" is green but the "Active" not on the PC Adapter. I would like to know if the problem is coming from my specific hardware or my settings? Thank you for the help ------------------------------------------------------------------------------------------ |

Hello, OK, if I want to buy a new cable, can I go with this one? https://support.industry.siemens.com/cs/products/6es7972-0cb20-0xa0/simatic-pc-adapter-usb?pid=10896&mlfb=6ES7972-0CB20-0XA0&mfn=ps&lc=en-WW Now I tested a connection with a CardBus CP5512 and it works good. If I would like to test the communication MPI between a CPU314 and a HMI OP77A (I don't have the hardware for the moment), can I use a standard Profibus cable? Because I don't have a Siemens MPI cable. I see it is possible in this topics https://support.industry.siemens.com/tf/ww/en/posts/cable-pin-outs-and-dip-switch-settings-for-tp177b-to-s7200-cable/30687/?page=0&pageSize=10 Can you please confirm that? Thank you very much |

Hello, yes with this adapter is possible, but is a older one which is phased out, the successor is: https://support.industry.siemens.com/cs/ww/en/pv/6GK1571-0BA00-0AA0/pi You can use a normal PROFIBUS Cable, this is no problem.
