VIDS is composed of software components and hardware components. The hardware components of VIDS consist of the items that are listed below:
VIDS ECM
Message center module
Keypad
Quad gauge module
Various switches
Sensors
Lamps
AlarmsThe software components are the input system, monitor subsystem manager and the operator interface. Data Links VIDS components communicate with each other, with other electronic controls on the machine and with systems off the machine through data links. VIDS uses the two data links that are listed here: Cat data link - This "2 wire data link" allows communication between the VIDS ECM and all machine control systems. SPI data link - This "4 wire data link" allows communication between the VIDS ECM and all display components. VIDS uses four types of data (information). The types of data that are used are listed here:
Sensed Data is read from the sensors. The sensors are communicating continuously with the VIDS ECM or other electronic control modules.
Internal Data is generated within the VIDS ECM. An example of internal data is the date and time.
Communicated Data is sent from other machine systems to the VIDS ECM through the data link. An example of communicated data is the engine speed. The engine speed is received from the electronic engine control.
Calculated Data is determined mathematically by the VIDS ECM. An example of calculated data is the event duration in the event list. VIDS alerts the operator of abnormal machine conditions that exist. All abnormal machine conditions are called data events. An example of a data event is high engine coolant temperature. The VIDS ECM also alerts the operator of problems in other electronic modules that are used on the machine. The VIDS ECM will also alert the operator of problems that occur within the ECM. These system failures are called system events. A typical example of a system event is listed here: The signal voltage of the hydraulic oil temperature sensor is above the normal limit. The VIDS ECM stores information about each event (data and system). This stored data can be used by service personnel while maintenance is performed on the machine. This data can also be used by service personnel to troubleshoot machine systems. DATA events are events that relate to a machine system. In
