Part Names and Functions Section 3-1
Normal Indicator
Display
The MS, NS, and TS indicators are all lit green when the status of all Units
and the Network are normal.
3-1-3 Switch Settings
Note The DeviceNet Communications Unit automatically detects and matches the
baud rate of the master, so the baud rate does not require setting.
Front Rotary Switches
Use these switches to set the node address as a slave in the DeviceNet net-
work between 00 and 63 (node addresses 64 to 99 cannot be used).
Set the ten's digit with the upper rotary switch, and the one's digit with the
lower rotary switch.
Any node address within the specified range can be set, as long as each node
in the Network (master, slaves, Configurator) has a different node address.
Note 1. Always turn OFF the DeviceNet communications power supply and EDU
power supply before setting the Unit.
2. The factory setting is 00.
3. If two or more nodes are set with the same node address, a node address
duplication will occur and the nodes will not be able to participate in com-
munications.
Copy Function
The DeviceNet Communications Unit can read and save the parameters of
the connected Temperature Controllers, allowing the parameters to be copied
to the Temperature Controllers when required.
