When using Fleet, the following extra window types can be configured:
- Truck Load
- Truck Load History
- Waiting Trucks
- KPI

Example of using main menu button to access "Configuration" > "Truck Load" | |
To open any of these windows, select the Menu key to open the main menu, then select "Configuration" > [window].
A Truck Load window shows the operator how full the next dipper should be to fill the truck to capacity. Colors help with warning the operator when the truck is nearing capacity.
Note: This window only appears to users with capability sets such as Fleet.
Note: This window cannot be used with Caterpillar electric rope shovel (Cat ERS) model 7495 machine types. (The window shows "Next Dipper 100%").
To add a Truck Load window, complete these steps:
- From the main menu, select "Configuration" > "Truck Load". The "Truck Load" dialog appears to allow the setup of percentage values and warning colors.
- Set up value and color selections for the dipper percentages.
The "Load Full", "Load Warning", and "Load OK" values work together to provide a range of dipper values.
Load OK - Indicates that the load is not near capacity
Load Warning - Indicates that the load is nearing capacity
Load Full - Indicates that the load is almost full
In a three-pass loading example that uses the default values, the first two passes will show a green dipper window with a value of 100%. This value indicates that the truck is not near capacity and that the next dipper can be 100% full.
Note: Using the Clear Truck command while loading a truck resets the "Next Dipper %" to 100% even if the next dipper should be less than100%. To prevent overloading a truck, avoid using Clear Truck while loading a truck.
On the third pass, the on-board software may calculate that the truck will be filled to capacity if the next dipper is 50% to 90% full. This calculation is based on an average of previous dippers. If this situation occurs, the window will be yellow. If the on-board software calculates that the truck will be filled to capacity if the next dipper is 49% to 0% full (empty), then the window will be red.
- Select "OK".

Once created, the Truck Load window can be deleted, but cannot be edited.
Note: Note: This section only applies to users of the on-board software with capability sets such as Fleet.
A "Truck Load History" window displays a bar graph of the loads for a specified number of the most recent trucks. The load history graphs are performance indicators of the ability of the operator to load the trucks to capacity. Performance can be displayed for either a single truck class, such as only 300 ton trucks, or for a mixture of truck classes.
The Truck Load History window can be configured to show one or more truck loads. The Truck Load History Window behaves differently when configured for a single truck. A single truck configuration is often referred to as Load Meter (see the Load Meter section for further

| Illustration 3 | g01172880 |
Illustration 3 shows two truck load history windows. The left window (1) indicates that the truck loads have been consistently loaded within capacity. The right window (2) indicates that the current truck has room for more material.
(1) - A truck load history window that displays a load status bar for each of the last ten truck loads. The most recent truck load is to the left.
(2) - A truck load history window that displays a single load status bar for the truck that is being loaded. The window is set up to display the truck load as dippers are added.
(3) - Indicates that the load capacity of the current truck is 236 tons
(4) - A line that indicates when the truck is in an overload status
(5) - A line that indicates when the truck is in an underload status
(6) - A green bar that indicates that the truck load was within the desired capacity
(7) - Indicates that the average truck load is at 98% of capacity
(8) - A red bar that indicates that the truck was in an overload status
(9) - A yellow bar that indicates that the truck was in an underload status
(10) - A yellow bar for the current truck that indicates the current load in the truck. The yellow bar updates as dippers are added to the trucks.
(11) - Indicates that the current truck contains 100 tons of material
Truck Load History Window with VIMS Input
Truck Load Histogram Behavior for VIMS
The Truck Histogram for the VIMS input includes the following behaviors:
- The Truck Histogram will respond to all VimsLoad inputs to Terrain for grading and loading by displaying the weight that the messages include.
- The Truck Histogram will not support dippers.
- The Truck Histogram will ignore Clear Truck, Send Truck and all other truck status messages. The Truck Histogram displays the weight from the latest VIMS message.
- During a Terrain session the Truck Histogram updates only when a new VimsLoad message is received.
- The Truck Histogram should not rely on the existence of a set loading truck. The Truck Histogram will display the weight within the VimsLoad message whether a truck is or is not set in a Loading state.
- Within the Truck Histogram, even is a truck is loaded back to back, each VimsLoad message creates a bar.
- The Truck Histogram is cleared and begins capturing new data after a restart.
- Terrain discards VimsPayload messages from Truck IDs that are not in the Truck.mwf file.
- Terrain will not consider the TMAC time stamp.
Load Meter is a term commonly used for a Truck Load History window that displays only a single truck
The Load Meter shows only the current loading truck. After a truck is sent, a new truck must be set in a Loading state before updates are added.
Manned and unmanned systems behave the same.
The Load Meter and Truck Histogram behaviors for inputs other than VIMS remain unchanged.
The Load Meter behavior for VIMS input is as follows:
- The Load Meter responds to all VimsDipper inputs to Terrain by displaying the weight that is included in the messages.
- The Load Meter ignores Clear Truck, Send Truck and all other truck status messages. The Load Meter displays the weight from the latest VIMS message as was the case in legacy Terrain v5.3.
- The Load Meter updates only when Terrain receives a new VIMS message.
- During the Terrain for grading and loading session, the Load Meter retains the last VIMS input weight until a new VIMS message is received
- The Load Meter does not rely on the existence of a set loading truck. The Load meter displays the weight within the VimsDipper message whether a truck is or is not set in a Loading state.
- The Load Meter is cleared and begins capturing new data after a restart.
- Terrain for grading and loading discards VimsDipper messages from Truck IDs which are not in Truck.mwf file.
The Load Meter for the VIMS input includes the following behaviors:
- The Load Meter shows the last VIMS input weight indefinitely during a Terrain session irrespective of Truck Clear, Truck Send, and input truck state changes.
- The Load Meter updates only on a VimsDipper input.
- The Load meter will show fluctuating weights if the office sends VIMS messages to Terrain that are out of synch.
- Terrain ignores the TMAC time stamp.
Add a Truck Load History Window
To add a Truck Load history window, complete these steps:
- From the main menu, select "Configuration" > "Truck Load History". The "Truck Load History" dialog appears.
Show/hide table
Illustration 4 g03498985 Truck load history dialog - Set up percentage values and warning colors.
Overload - If set up with an Overload value of 110 and the color red, any truck load filled to 110% capacity or greater will appear as a red bar that reaches above the 100% capacity line. The percentage calculations are based on the payload of the current truck being loaded and the capacity of this truck as contained in the MineStar (*.mwf) truck file.
OK - If set up with an "OK" label and the color green, any truck filled between 90% and 110% of capacity (overload and underload) will appear as a green bar. The bar will rest under the 100% capacity line and above the underload capacity line.
Underload - If set up with an Underload value of 90% and the color yellow, any truck load filled to 90% of capacity or less will appear as a yellow bar. The bar will reach below the underload capacity line.
Capacity - This field acts as a filter. Any truck capacity that matches the configured number will be displayed in the payload history window. For instance, if the payload history window is to show only the payload history for trucks with a capacity of 100 tons, type 100 in this field. If no value is set in this field, then the history for all truck classes will be displayed in the window.
Load Count - The Load Count field specifies the number of loads that will be displayed in the truck load history window. If creating a window that displays only the current payload, enter the number "1" in this field. The left window (1) in illustration 3 is set up with ten load counts. The right window (2) in illustration 3 is set up with one load count.
Range (+/-) - The Range (+/-) fields specify the maximum and minimum percentages that will be displayed in the payload history window. If the left (+) value is 140, then the vertical bar for a load filled to more than 140% of capacity will reach beyond the top of the display window. If the right (-) value is 30, then the value for a load filled to less than 30% of capacity will register at the baseline of the vertical bar.
Display Dippers - If the vertical bar for the current truck load is to be displayed incrementally as dipper information is known, select the "Display Dippers" checkbox. If this box is not checked, the vertical bar will be displayed only after the information for the entire load is known. Select this option If a window that displays only the current payload is being created. The left window (1) in illustration 3 is set up with the Display Dippers option unselected. The right window (2) in illustration 3 is set up with the Display Dippers option selected.
- Select "OK".
Once created, the Truck Load History window can be deleted, but cannot be edited.
A Dipper Load History window displays a bar graph of the dipper loads for a selected number of previous dippers. Sites can monitor the ability of the loader operator to load the dippers to capacity (height of each bar).
For additional information about setting up the window, refer to "Dipper Load History Window" in the MCU Help file.
Payload is a term referring to the weight in a dipper and is confined to loading machines only. The payload may be in metric or non-metric units, and in standard or non-standard gradations of that unit.
Use the following references in the MCU Help file to understand the payload units and how the units appear in the on-board software:
"Terrain Display Units" setting - Units that are used on the Terrain display module
"MCU Display Units" topic - Units used on the MCU display
"Units Conversion" setting - Units used for converting GPS coordinates
"Payload Conversion" setting - Conversion factor used to display the payload in the All Dippers window and the Truck Load History window
"Use Cat ERS Dipper Weight" setting - Units associated with the Cat electric rope shovel (Cat ERS) model 7495
Units set in Cat MineStar System office software which come through as hardcoded values in the MCU - See Cat MineStar documentation for more information.
Known Issue v4.1 - Truck Load History for Surface Miner Machine Type
In standard ore control applications, truck load information is detected by the action of a large load of material activating a switch in Fleet. Fleet informs the on-board software, which in turn shows the amount of material loaded in the truck on the Truck Load History window.
Surface miners use a conveyor which fills the truck slowly. There is no large load to activate the switch causing Fleet to detect truck load information irregularly.
The Truck Load History window will not accurately show how full the truck is. Operators must look to see the amount of material in the truck.
When this loading issue is resolved, the on-board software will not only show the truck load, but will warn the operator when the truck is almost full. The Truck Load History window and a Truck Load Alarm buzzer are linked. The buzzer sounds when the load in the current truck reaches the Alarm Triggered (Percentage) level.
A "Waiting Trucks" window displays a truck icon and some text columns with the following information about trucks being loaded or waiting to be loaded:
- Truck name
- State
- Operator name
- Material being loaded
- ETA or estimated time of arrival
- Side of loading truck is double-side loading
To add a Waiting Trucks window, complete these steps:
- From the main menu, select "Configuration" > "Waiting Trucks". The Waiting Truck window fills the entire screen on the display.
- Using the cursor, resize the Waiting Truck window.
- Using the cursor, complete these steps to resize the columns within the Waiting Trucks window:
- Hover the mouse between the two columns that are to be adjusted until a double-headed arrow (12) appears.
- Click and hold down the left mouse button while dragging the column.
The column can be adjusted to the desired size, or column can be adjusted so that the window is no longer visible on the screen.

Note: This section only applies to users with capability sets such as Fleet.
A KPI window displays "Key Performance Indicator" information to the operator. KPI information could be information such as tons hauled by the truck during the current shift, or tons hauled by the operator of the truck team during the current shift.
This information allows the truck operator to be aware of performance information. For example, the target for the operator may be to load 100 trucks per day. If the current load is set to "10", then the KPI is 10%.
Different types of targets can be set up for the operator. Individual KPI windows can show different targets. A single KPI window can toggle between different targets. The targets are defined in the MineStar KPI file, KPI#.mwf.
Reference: For the definitions of these targets, refer to "List Files" section of this manual.
A KPI message from the office software contains an identity that matches a record in the MineStar KPI file. This message identifies the target. The message contains a window identity that specifies the KPI window in the on-board software. The message also contains the target value and the current value. The specified KPI window updates to show this information.
To add a KPI window, complete these steps:
- From the main menu, select "Configuration" > "KPI". The "Create KPI Window" dialog appears.
- Enter an identification number for the window In the "Window Id" box . This number must match the ID that the office uses when sending out KPI messages.
- By default, the window will be displayed as a horizontal bar graph. If the window is to appear vertically, select the "Vertical" checkbox. If a graph is not needed, then select the "No Graph" checkbox. If the "No Graph" check box is selected, only the KPI text and the percentage are shown in the window.

Use "All Dippers" and "Truck Load History" windows with Vital Information Management System (VIMS).
The truck VIMS reports when a dipper is loaded into the truck and also when the truck is loaded. The on-board software uses the VIMS Dipper reports and the VIMS Truck Loaded reports from the truck to display truck load history.
Dipper and Truck Load History or "Payload" windows are typically used on loading machines, rather than on trucks. The windows are used to help loading machine operators load a truck to capacity. Based on the payload information for the current truck, the Dipper window shows the operator how full the next dipper should be to fill the truck to capacity.
A Truck Load History window displays a bar graph of the loads of the past several trucks loaded by the loading machine operator. This bar graph displays the past performance of operator in loading the trucks to capacity.
When a VIMS dipper weight is less than the previous VIMS dipper weight received, the system assumes that the lighter dipper weight is the first dipper for a new truck.
Terrain v6 and above supports the LoadRite system for excavators. LoadRite calculates a payload weight for individual bucket loads and combines the weights into a total truck load weight
When Terrain detects LoadRite, all other dipper weight inputs are ignored. LoadRite and VIMS cannot work together. When LoadRite is no longer detected, Terrain must be restated without LoadRite connected to use VIMS.
LoadRite weights are used in all MineStar TMAC messages that contain weight information. The weight units are usually in Tonnes = metric ton.
