While wiring considerations alone can justify vehicle networks, end users find that the network provides an additional benefit. The advanced diagnostic capability allows for the immediate awareness of unstable conditions. When a device is broken or worn, the problem may remain undiscovered until equipment failure, or other more serious problems occur. Electronic Innovation vehicle networks perform internal self-diagnostics and are able to report the working status of each device over the network. When a fault does occur, diagnostics identify the location of the fault. This eliminates the time-consuming process of tracing faults back through the wiring harness
The Electronic Innovation Inc. "DN" line of modules is intended to provide rugged, reliable, DeviceNet I/O capability in unusually harsh environments. These include applications such as on-board control of heavy mobile equipment. The DN line has been designed from the ground up to survive these environments with special attention in the following areas:
Mechanical design for high shock, vibration, and concussion tolerance, resistance to liquids such as water or oil, and most forms of corrosion, along with wide operating temperature ranges.
Electrical design to ensure reliable operation in the face of severe electrical transients, which can occur on vehicle electrical systems. All modules have been designed and tested according to automotive standard SAE J1113 and mil spec QSTAG-307
Electronic design to minimize electromagnetic emissions and provide low susceptibility to external electromagnetic interference.
Extensive design effort has been expended to ensure that hardware, software, or network faults, if and when they occur, will result in a predictable and timely transition of the module to the safest achievable state.
