Adapter 6ES7-972-0CB20-0XA0 cannot connect (directly) to Sinumerik 840D PLC, none of the interfaces on Sinumerik has the 24V supply for the adapter. If you really insist on using this adapter you must make an "MPI connector with 24V supply": open an MPI/PROFIBUS connector and solder wires to pins 7 = 24V and 2 = Ground. In this way you supply the adapter (or destroy your interfaces if you do it wrong). Another option is to use A2 adapter: 6GK1571-0BA00-0AA0 this one is using 5V from USB for supply. |
