check for a color match and update the discrete outputs until the Trigger input is deactivated. The
discrete outputs will remain in the state that they are in when the Trigger input is deactivated. When
Edge is selected, the sensors will check for a color match on each rising edge of the External Trigger
input and update the discrete outputs. The discrete outputs will remain in the state that they are in when
the Trigger input is deactivated. The External Trigger input is generally used when a separate proximity
sensor detects the presence of a sample and signals the sensor to check with the pre-programmed color
recognition channels to determine whether there is a match. Alternatively, the sensor can be operated in
the Free Run mode, and a separate proximity sensor can be connected to the data acquisition system or
PLC indicating a sample is present and the discrete output is valid.
Minimum Output Duration (ms)
Selections: 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
Default = 0
The minimum output duration setting allows the user to increase the time that the discrete output(s)
indicate a match. When “0” delay is selected and a color match occurs, the appropriate channel’s
discrete output becomes active (i.e. changes state) as long as the match criteria is met. When a target is
moving at high-speed, presence of the target may be too short for the polling cycle of the data
acquisition system or PLC. In this case, increasing the minimum output duration lengthens the discrete
output signal, allowing it to remain active long enough for the acquisition system to read its input port.
Illumination (%)
Adjustment range = 0 – 100%
The BFS 30M Color Sensor allows the user to optimize the sensitivity of the sensor by adjusting the
illumination level to prevent the sensor from saturating. The illumination setting must be adjusted prior
to teaching the color recognition channels. Changing this setting after teaching will affect channels
selected for Color & Luminosity mode.
Read BFS 30M Color Sensor Settings
The Read BFS 30M Color Sensor Settings button causes the application program to read the current
settings from the sensor and display them in the Sensor Settings section.
Send BFS 30M Color Sensor Settings
The Send BFS 30M Color Sensor settings button causes the application program to send the selected
settings to the sensor. When changes are made to the Sensor Settings section the Send BFS 30M Color
Sensor Settings button must be selected to transmit the settings to the sensor.
Sensor Communications
The Sensor Communications section provides user control of PC COM port selection and displays
specific sensor information.
Port
The user may select the appropriate PC COM port for sensor RS232 communications.
Communication Status
The Communications status box shows the BFS 30M Color Sensor model and the connection status,
either on line indicating normal communication or Communication lost indicating a disruption in
