Different firmware acs 850 drive on devicenet network , i
i had 6 acs 850 ( 2300) drive on the devicenet network , all of them wi same firmware revision, and working fine on the network.
Recently i replaced one drive which is having latest firmware acs 850(2700) . When I registered eds file for this drive i was able to communicate with this drive but now i am not able to upload parameter of remaining drives which are having older version of firmwar.
once highter version eds is registered on the network , it overrides older versions. Since older version drives parameters group is different from latest drive , upload/ download will not work.
can anyone help me out on this ?

you can obtain from your local ABB sales network the old FW version 2300 for the last drive.
Remember to comunicate the serial number inside the Memory Unit of your new drive.
The procedure to dowload the old version of firmware is really simple, but need a little confidence with this procedure. If you not have to do before, may be you can ask to your ABB drive service.
Of course you need to restore the old EDS file in your network.
Hope this help you
