Introduction
This manual provides information about the DeviceNet module
(MDCOMM-DNET) and using it with MD65 drives. The module is
mounted in the MD65 drive and receives its required power from the
drive and from the DeviceNet network.
This manual is intended for qualified electrical personnel familiar
with installing, programming, and maintaining AC drives and
DeviceNet networks.
1.1 DeviceNet Module Features
The DeviceNet module features the following:
• Switches that enable you to set a node address and network data
rate before applying power to the drive. Alternatively, you can
disable the switches and use parameters to configure these
features.
• A jumper that allows you to select between Single- or Multi-Drive
mode of operation. In single mode, the module represents one
single drive on one node. In Multi-Drive mode, the module
represents up to five drives on one node.
• A number of configuration tools that can be used to configure the
module and connected drive. The tools include the Operator
Interface Module (OIM) on the drive, network software such as
RSNetWorx for DeviceNet, or drive-configuration software such
as VS Utilities.
• Status indicators that report the status of the drive
communications, module, and network. They are visible both
when the cover is opened and when it is closed.
• I/O, including Logic Command/Reference, that 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), that can be used to transmit data between
the network and module.
