Page 40: Screen Item Object Dictionary Locations
Screen Item Object Dictionary Locations There are 10 OD entries which are for configuration of the items that can be displayed on the screen. These are at location 0x2900 to 0x2909. Each object fully defines one screen item. Each item has a set of sub-index items which are used to control the appearance of the item. The exact functionality varies depending on the type of item selected. - Page 41 Configuring the Display Sub 1 – Item Type The item type is selected according to the table below: Data Description Example Image No Item This entry is not used Ellipse graph.

Page 44: The Arc Graph
The Arc Graph The arc graph is a curved analogue graph. This is intended to show a variety of data including speed and motor RPM. The graph is constructed from the data parameters which can fully control the shape and appearance on screen. - Page 45 Configuring the Display To finally create the arc graph shape we define the start angle and end angle. The display will then create a bounding rectangle around the remaining arc, ready to be drawn onto the screen, e.g.: In this picture the blue rectangle contains the arc that will be seen on screen. The start and end angles in this case were (approximately) start at 15, and end at 165.
- Page 46 Sub 10 Data 5. Graph thickness. Sub 11 Data 6. Maximum value displayed Sub 5 – Style flags The style flags are contained within an U16 item. The flags help to define the operation of the item. The following attributes can be configured: Direction of the graph fill.
- Page 47 Configuring the Display Sub 11 – Maximum range This defines the maximum range of the graph. The operation of this depends on the signed / absolute setting: If graph setting absolute: If maximum range is less than the maximum for the referenced data object, then the maximum on screen range will be according to this item.

Page 48: The Bar Graph
The Bar Graph The bar graph is a rectangular analogue graph. This is intended to show a variety of data including speed and motor RPM. The graph is constructed from the data parameters which can fully control the shape and appearance on screen. - Page 49 Configuring the Display 00 = signed values 00 = fill upwards 00 = no tick marks 01 = absolute values 01 = fill downwards 01 = tick marks left or top 10 = fill to the right Sub 6 & 7 – (x,y) Size These items defines the x and y size of the outer rectangle shape used to create the frame.

System Information The first time the display is powered on, and detects some connected Sevcon nodes it will interrogate the nodes to determine the system configuration. This “system info” is then stored in the display so that on subsequent power cycles it can start up more quickly. - Page 63 Local CAN Bus Settings The stored information can be cleared using the “CANbus-Clear System Info” parameter. Setting this item to ‘yes’ will cause the stored information to be erased. On the next power cycle the information will be re-acquired and stored. The System configuration is determined from the VPDO and PDO settings that have been configured on the controllers on the vehicle.
