Traffic Lights / Web Switch
Setup and configuration for the Web Switch Plus device connected to Traffic Lights to use in Fast-Weigh Ticketing.
Traffic Lights work through Fast-Weigh via a Web Switch that allows the software to send a command to toggle the switches on and off. These Web Switches have one Ethernet Port for network connections, and two outlets for the Traffic Light to connect to.
Traffic Light Network Configuration
To use the Web Switch, it must be set to the same IP Scheme as your existing network so it can be reached by other devices your network. This typically involves setting specific IP/Network configuration settings on a computer that can reach the device to initially connect and set up the WebSwitch. If you are unsure how to do so, please consult an available IT professional.
A Quick-Start Guide with some relevant details to this can be found here: https://controlbyweb.com/wp-content/uploads/2024/03/webswitch-plus-qsg_v2.3-2x2-1.pdf
Additional Relevant Information:
Default Username: admin
Default Password: webswitch
Switch Outlet 1: Green Light in Fast-Weigh
Switch Outlet 2: Red Light in Fast-Weigh
Once the Web Switch is configured to your network, and your traffic light is connected to your webswitch, and given their relays are named, you can begin the process of configuring it in Fast-Weigh.
Traffic Light Fast Weigh Setup
ControlByWeb WebSwitches has had some firmware changes that alter some of the integration steps between the device and fast weigh. Please check what firmware version of the WebSwitch you are using before proceeding further under the appropriate tab. For more information, please visit ControlByWeb Firmware
Firmware 3.12+
In Fast-Weigh Ticketing, go to Server Settings.
Under the Manage Devices area, select Add Device.
Server Settings > Add Device > Traffic Light In the field labelled Device Type, choose Traffic Light.
Name the device.
Next insert these URLs in [ Green Light IP Address ] & [ Red Light IP Address ] , but replacing the <ws-ip> with your web switch's IP Address.
Green Light
http://<ws-ip>/state.xml?relay1State=1,http://<ws-ip>/state.xml?relay1State=0
Red Light
http://<ws-ip>/state.xml?relay2State=1,http://<ws-ip>/state.xml?relay2State=0
Fill out remaining fields as needed:
Signal On Inbound: Enable to signal the traffic light when an inbound ticket is created.
Signal On Tare: Enable to signal the traffic light when a truck is Tared on the scale.
Note, Ticket Creation will trigger the signal as well.
Light Delay (in Seconds): Amount of seconds before the signal to trigger the light reaches the switch. If set to 5 seconds, it will take 5 seconds for the light to switch after signaling the input in Fast-Weigh.
Fully configured example for a traffic Light. Assign device to the Lane in the Manage Lanes section with the drop-down selector labelled Light.
Assigning the Traffic Light to the Lane. The traffic light will automatically trigger if you have the On Inbound or On Tare settings enabled.
If not, you can manually trigger the light from the ticketing menu using the indicator symbols on the bottom right. (Red and Green circles for each light respectively.)
Manual triggers for the traffic lights.
Legacy Firmware ( pre 3.12 )
In Fast-Weigh Ticketing, go to Server Settings.
(You must have appropriate User Permissions to access these settings).
Under the Manage Devices area, select Add Device.
Server Settings > Add Device > Traffic Light In the field labelled Device Type, choose Traffic Light.
Name the device.
Next fill out all of the relevant fields and choose the options you wish to be enabled. The following is a breakdown of these fields:
Green Light IP Address: IP/Network Address of the Web Switch. This is for Outlet #1.
Red Light IP Address: IP/Network Address of the Web Switch. This is for Outlet #2.
This should be the IP/Network Address only, with no http:// or https:// in front of it. These two IP/Network Addresses will typically be the same unless you are running two independent Web-Switches.
Signal On Inbound: Enable to signal the traffic light when an inbound ticket is created.
Signal On Tare: Enable to signal the traffic light when a truck is Tared on the scale.
Note, Ticket Creation will trigger the signal as well.
Light Delay (in Seconds): Amount of seconds before the signal to trigger the light reaches the switch. If set to 5 seconds, it will take 5 seconds for the light to switch after signaling the input in Fast-Weigh.
Fully configured example for a traffic Light.

Assigning the Traffic Light to the Lane.
The traffic light will automatically trigger if you have the On Inbound or On Tare settings enabled.
If not, you can manually trigger the light from the ticketing menu using the indicator symbols on the bottom right. (Red and Green circles for each light respectively.)
Additional Traffic Light Configuration
Light Always Shows Red, Unless Green
There are additional settings that can be adjusted for the traffic light and Web Switch in order to have it stay Red and only show Green temporarily (for a set number of seconds). Setting this up requires uploading a text file to the Web Switch in a specific configuration area so it knows to function this way. The following steps will go over how to do this and also includes the text file needed:
Connect to the Web Switch via a web browser by inputting it's IP/Network Address ending with "/setup.html".
If the Web Switch has an IP address of 192.168.0.150, then the web address will be "192.168.0.150/setup.html".
Enter the Login information if prompted.
Default Username: admin
Default Password: webswitch
Navigate to the Script section in the settings menu.
Download the following .txt file below.
Edit the file with any text editor, and input your corresponding relay names where <relay-name> appears. Then save.
DO
IF io.<GREEN-light-relay-name> = 1 THEN
LET io.<RED-light-relay-name> = 0
ELSE
LET io.<RED-light-relay-name> = 1
END IF
LOOP
ENDSubmit the edited file by selecting [ Choose File ] and [ Submit ]
Ensure that RUN Script is set to Yes.
Select Submit to finish uploading.
If these steps were done correctly, you should have something like this showing on the Script page:
In order to finish this configuration, you MUST completely power off the Web Switch for a few seconds, then power it back on.
Now that it's powered off, you can use the Fast-Weight device settings to determine the length of time before the Green light turns off, which will switch it to Red. The Traffic Light device setting in Fast-Weigh labelled Light Delay (in Seconds) should now determine how long the light stays on Green before changing back to Red.
