  1. Brett, Writing 1151 (start) and 1150 (stop) does start and stop the drive, i also wrote the speed to the drive modbus adress 1. In order to let the drive turn the other way you have to use negative numbers. You can do this with writing multple vectors but i chose to create more nets and reading and writing 1 vector at a time. I also made a net to read the actual speed at adress 4. When you whant to read and write more data from and to the ABB drive you can download the ABB documentation from their website with the modbus adressing table. Gert P.
