Hardware Installation and Configuration
Follow these steps to set the ControlNet network address for the linking
device.
1. Choose and set a network address.
2. Write the network address setting in the space provided on the linking
device label.
3. Apply (or cycle) power to the linking device to enable the new network
address.
4. Make the same address changes in your NI-FBUS configuration
software.
Interpreting the LEDs
Module STATUS LED
The STATUS LED is located on the front of the linking device, between the
two Fieldbus connectors, as shown in Figure 1.2. It indicates whether the
linking device is powered, configured, and operating properly. Table 2.A
shows how to interpret the STATUS LED states.
Standby state indicates the linking device has passed all self tests and is
ready to operate. Yet, it is not functioning because of a lack of
configuration.
Operational state indicates the linking device has left standby state because
the necessary network configuration (if any) has occurred.
For optimum throughput, assign network addresses to your ControlNet
nodes in a sequential order starting with 01 for the PC running the
configuration software.
