This window summarizes the device addresses and resources (output devices/ relays and RTD inputs) that have been found by the
system and can be used for setup.
Fig. 3.34 Network | Devices window
Pressing this button starts a search/scan for all connected peripheral devices. When the scan is completed, the window displays all
devices and RTDs found connected to the NGC-UIT3.
If expected devices or RTDs are not discovered on the first scan, Update Network may be pressed a second time.
If a known device or RTD is not discovered, check for proper connection to the RS-485 wiring, power at the peripheral device, and
possible address conflicts (no two peripheral devices can have the same address setting).
Use the Update Network button whenever a new device or RTD is added to the system.
To add a new device or RTD, make sure it:
1. Has a unique address
2. Has power
3. Is connected to the RS-485 wiring
