I'm putting together a system that will include an Allen Bradley Ultra V 3000 drive. The drive will need to follow a pulse train at a ratio to be set by the operator. The ratio can vary over a defined range. Once the ratio is established, it doesn't need to change until the operator decides to enter a new one.
I see where I can configure one (or more) of the drive's digital inputs to put it into follower operation at the stored follower ratio. I am considering using the DeviceNet interface to set the ratio.
My question is, can I use a MicroLogix 1100 with a 1761-NET-DNI module to pass the ratio? The manual for the NET-DNI module says it can be set up as a slave or as a peer, but not as a master. The DeviceNet manual for the Ultra V 3000 says it can only be a slave. Can a peer pass data to and from a slave or do I need a master on the network?
If I have to have a master, what is the minimum PLC model I need? Are there any MicroLogix models that can be DeviceNet masters or do I need to move up to a SLC or Compact Logix controller? The PLC task for the project isn't very sophisticated, so the smallest PLC capable of transmitting motion parameters to the Ultra V drive will be capable of handling the rest of the logic.
