Product Overview
Description
The DeviceNet Interface is a stand-alone, DIN rail or panel mounted,
intelligent DeviceNet to DF1 protocol conversion device that allows
existing DF1 devices to communicate on DeviceNet. The DF1 device is able
to exchange I/O data with a Master device and is able to originate and
receive DF1 encapsulated DeviceNet messages across DeviceNet.
The DNI provides a single DeviceNet connection point and a single RS-232
connection. The DeviceNet port is isolated from the DNI digital logic and
RS-232 port.
The primary functions of the DNI are threefold:
•
to collect or receive input data from the DF1 device connected on its
RS-232 port and forward that data to a connected master on DeviceNet
•
to monitor output data received from the DeviceNet master and write that
data to the DF1 device
•
to allow DF1 devices to send and receive messages across the DeviceNet
network
Operating Modes
The DNI can be used in either or both of the following modes:
•
peer-to-peer
•
DeviceNet slave
Device Compatibility
The DNI can be used to interconnect the following devices:
•
MicroLogix controllers
•
DF1 Full Duplex compliant products, for example: PLC-5
®
programmable controllers, operator interface devices, and SLC 5/03™
and higher processors
