Field Monitor Indicators

Each station row displays up to eight indicator cells. On smaller screens some columns are hidden - the full set is visible on tablets and desktops.

DS (Driver Station)

Shows the connection state between FMS and the team's Driver Station laptop.

Color / Label	State	What it means
Red	No link	Ethernet cable is not connected or no link light
Green	Connected	FMS has a good DS link
Green + X	No FMS comms	Ethernet is plugged in, but DS isn't communicating with FMS
Yellow + M	Move Station	Team is plugged into the wrong station; their DS will tell them where to go
Yellow + W	Waiting	FMS is waiting for the team
Dark red + B	Bypass	Station has been bypassed by the scorekeeper
Dark red + E	E-Stop	Emergency stop has been activated
Dark red + A	A-Stop	Autonomous stop has been activated

Radio

Shows whether the robot's radio (OpenMesh OM5P-AN or similar) is communicating with the field access point.

Color	State
Green	Radio link established
Red	No radio link
Green + X	Field can see the radio MAC address but the robot hasn't connected yet

RIO (roboRIO)

Shows whether the roboRIO is communicating over the robot network.

Color	State
Green	RIO is communicating
Red	RIO not detected
Green + X	RIO is up but robot code is not running

Code

Indicated by the RIO cell. If the RIO cell is green with no X, robot code is running. A green X means the RIO is online but code has not started.

Battery

Displays the current battery voltage as a number (e.g. 12.4v) overlaid on a small rolling graph showing the last 20 readings.

Background turns red when voltage drops below ~11V.
A small secondary voltage in gray/red below the main number shows the 2nd-percentile voltage since the match started - a low value here indicates the battery is sagging under load.
Red secondary text appears when the 2nd-percentile is below 7.8V.

Ping

Shows the round-trip time in milliseconds between FMS and the robot.

Background is clear for low ping (normal).
Background becomes increasingly red as ping climbs above 20ms.
Displayed as a rolling graph.

BW (Bandwidth Utilization)

Shows the current bandwidth usage in Mbps as a plain number. High values can indicate streaming, excessive logging, or network issues.

Signal

Shows the radio signal strength in dBm with a visual signal bar icon:

Icon	Level	dBm
3 bars (green)	Excellent	> -60 dBm
2 bars (yellow)	Fair	-60 to -70 dBm
1 bar (red)	Poor	-70 to -80 dBm
No bars	No signal	≤ -80 dBm

The raw dBm value is shown as a small number above the icon.

Last Change

On larger screens, a small timestamp shows how long ago the last state change occurred for this station. Useful for knowing when a robot disconnected or reconnected.

Compact View (Mobile)

On smaller screens, Ping, BW, and Signal are collapsed into a single Net cell that shows all three values stacked vertically (e.g. 12 ms / 0.50 / -65 dBm).
