I like Toshiba in general, as I mentioned I have dealt with many G7 drives. IF the cost is going to be real high then you may want to look at the G7 with the optional ASD board for profibus. I did a job a couple years ago with several machines involved and the PE used the G7 on Devicenet. I had a few issues, like wrong comm board orginally installed on the drive, but Toshiba quickly remedied that problem. These systems were using Horner PLCs with Devicenet, it was fairly simple to work with overall.
