Setup and Wiring
3-1-3 Operation Indicators
The DeviceNet Communications Unit/Card has 2 operation indicators that show the status of the
power and communications as described in the following table.
3-1-4 Node Address Settings
A unique number (called a node address) is assigned to each Master/Slave in order to manage com-
munications in the network.
There are two ways to set the node addresses. The node addresses can be set with the rotary
switches on the DeviceNet Communications Unit/Card or from the Configurator.
■ Setting the Node Address with the Rotary Switches
Set the 10s digit with the left switch and the 1s digit with the right switch (up to node address 63).
When the node address is set to a value between 64 and 99, the node address can be set from the
Configurator. (See Configurator setting procedure below.)
Note The Unit/Card reads the node address setting on the rotary switches when the power is turned
ON.
Indicator Display Meaning
Color Status
MS Green Lit Power is being supplied and the Unit/Card is operating normally.
Flashing Initial settings or necessary preparations for communications are incom-
plete.
Red Lit A fatal error (hardware error) has occurred in the Unit/Card.
Flashing A non-fatal error, such as a switch setting error, has occurred.
--- Not lit Power is not being supplied from the Inverter.
The Unit/Card is not connected properly and power is not being to supplied
to it.
NS Green Lit The DeviceNet Network is operating normally.
(Online and communications connection established.)
Flashing The Network is normal, but the communications connection with the Master
Unit is not established.
Red Lit A fatal communications error has occurred.
A DeviceNet communications error was detected caused by node address
duplication or Bus OFF. (These errors make communications impossible.)
Flashing A non-fatal communications error has occurred due to communications time-
out.
--- Not lit A DeviceNet Network error has occurred (offline). For example, the Network
does not exist, power is not supplied to the Unit, or the baud rates do not
match.
