Is it possible to connect ACS880 to two separate networks?
On the ACS880, two net adapters can be installed. The adapters can have different IP addresses.
Is it possible to connect the drive to an AC800m controller with for example profinet through FPNO-21, and at the same time establish a network for "Drive Composer Pro" through a second net adapter?
(to segregate online maintenance from control network)
I think it is possible, because ACS880 is designed for two different field bus connection devices.
A little more difficult is the concept of segregation between maintenance, done with the Drive Composer Pro tool and the primary network towards the DCS.
Every action made through Drive Composer Pro has immediate effect on the drive, so I need to better understand what you mean by separation between maintenance operations and AC800M network operation.
