Features

The DeviceNet adapter features the following:

• The adapter is mounted in the PowerFlex drive. It receives the

required power from the drive and from the DeviceNet network.

• Switches let you set a node address and network data rate before

applying power to the PowerFlex drive. Alternatively, you can

disable the switches and use parameters to conﬁgure these features.

• Captive screws are used to secure and ground the adapter to the

drive.

• A number of conﬁguration tools can be used to conﬁgure the adapter

and connected drive. The tools include the PowerFlex HIM on the

drive, network software such as RSNetWorx for DeviceNet, or

drive-conﬁguration software such as DriveExplorer (version 2.01 or

higher) or DriveTools 2000 (version 1.xx or higher).

• Status indicators report the status of the drive communications,

adapter, and network. They are visible both when the cover is opened

and when it is closed.

• I/O, including Logic Command/Reference and up to four pairs of

Datalinks, may be conﬁgured for your application using a parameter.

• Explicit and UCMM (Unconnected Message Manager) Messages are

supported.

• Multiple data exchange methods, including Polled, Cyclic, and

Change of State (COS), can be used to transmit data between the

network and adapter.

• Master-Slave or Peer-to-Peer hierarchies can be set up so that the

adapter and connected PowerFlex drive transmit data to and from

either a scanner or another PowerFlex drive on the network.

• User-deﬁned fault actions determine how the adapter and PowerFlex

drive respond to communication disruptions on the network and

controllers in idle mode.

• Faulted node recovery is supported. You can conﬁgure a device even

when it is faulted on the network if you have a conﬁguration tool that

uses faulted node recovery and have set the data rate switch to

"PGM" (Program). With the PGM setting, the adapter uses

parameter settings for the data rate and node address instead of

switch settings.
