Hello,

Please can you give the MLFB number of the adapter you use?

Perhaps this link is helpful:

Which connector cables are available for connecting to SIMATIC Panels?

Best regards,

 hi Mr WIZARD

the number for my adapter is ( PC Adapter USB(6ES7 972-0CB20-0XA0))

when i m in the profibus network for the machine it s ok i can uplaod the back from the panel, i have no probleme, but when i went work in my office with this panel for uploid the backup without stope the machine , she can't communicat ni with profibus parametres ni with mpi...

dear wizad

it s ok but with this adapter, i have an uploid for this panel when it s in network, i ask for wths the deffirents betoin when we are in network and when we are hors network

If you wish to connect directly to a panel, you need PC Adapter USB A2. This adapter gets the operational voltage from the computers USB port. The older model PC Adapter, needs a partner that will supply the operational voltage.

 hi Mr hati,

with y adapter i can uploid the backup when the panel is run in original network profibus, hors this network i can't runing the communication,

for the voltage, i have all led is run ( MPI=green, usb= green , power= green)

if the power is the probleme, i m instal the panel in an other network profibus (not the original) but i cant upload the backup ( but when the ihm is in original profibus it s ok i can upload the backup wethout no probleme... i ask wher is the différence)!!!!

 When the panel is connected to the network, where exactly do you connect the PC Adapter? To a biggy-pack connector on the PLC or? If you connect the PC Adapter like this, the you get the operational voltage from the PLC.

What is the status of the PC Adapters LED's when you have the HMI on the table on you connect directly to the HMI with PC Adapter?

 my adapter connected in network in the profibus cable (connecteur profebus with resistor is in off) it s work good, but whin i connected the panel in an other profibus network sche can't connected, and with out the profibus cable, directly to the port DB9 for the panel not work, .. waths is the different!! possible the adress?
