The 1761-NET-DNI DeviceNet Interface
The DeviceNet Interface (DNI) is an intelligent DeviceNet-to-DF1 protocol
conversion device that let existing DF1 devices communicate on DeviceNet
network. The DF1 device is able to exchange I/O data with a master device
and is able to initiate and receive DF1 encapsulated DeviceNet messages
across a DeviceNet network.
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:
• to collect and receive input data from the DF1 device connected on its
RS-232 port and forward that data to a connected master on a
DeviceNet network.
• to monitor output data received from the DeviceNet master and write
that data to the DF1 device.
• to let DF1 devices send and receive messages across the DeviceNet
network.
The DNI can be used to interconnect:
• MicroLogix controllers.
• PLC-5 programmable controllers.
• operator interface devices.
• SLC 5/03, SLC 5/04, and SLC 5/05 processors.
