Operate the DeviceNet Interface
Initial Power On Before you apply power to the DeviceNet Interface, verify that it is
properly connected to the power supply, to the bus connectors and to
the basic unit. Then, switch on the power supply for the basic unit
and the DeviceNet Interface.
The LEDs of the 1760-DNET flicker.The device automatically detects
the correct baud rate (see Data Transfer Rates – Automatic Baud Rate
Recognition on page 2-4). The GW information (intelligent station
connected) is displayed on the basic unit.
When the device in the network management is switched to the
‘Operational’ status, the state of the GW changes to static even on the
devices with a flashing GW,(see Network Status LED (NS) on
page 3-5).
If the unit has default configuration (node ID = 127), you need to
define the DeviceNet slave address.
DeviceNet Setting the
Slave Address Each DeviceNet slave requires a unique address (MAC ID) in the
DeviceNet structure. Within a DeviceNet structure, you can assign a
maximum of 64 addresses (0 to 63). Each MAC ID must be unique
within the entire bus structure.
There are three ways to set the DeviceNet address of an 1760-DNET:
• Using the integrated display and keyboard on the basic unit
• Using Pico-Soft V3.01 or higher on the PC
• Using Pico-Soft Pro on the PC
• Using the configuration software of the installed master
programmable controller (possibly by means of an explicit
message).
Set the Address on the Controller Unit with Display:
Make sure that:
• The respective basic units and DeviceNet Interface are supplied
with voltage.
