DeviceNet is a communication protocol based on CAN that is used primarily in factory automation and maintained by the ODVA (Open DeviceNet Vendor Association). DeviceNet is primarily to realize master slave network with plug & play characteristics.
Features and Advantages:
In addition to the CANalyzer's high-performance functionality, the DeviceNet extension gives the user a tool that can be used for initial production of the DeviceNet project. The DeviceNet-specific extensions allow the user to concentrate on the actual tasks of data analysis, without detailed knowledge of the DeviceNet protocol. This significantly increases the efficiency when searching for errors. Misinterpretations of CAN frames are avoided as well.
Functions:
CANalyzer.DeviceNet expands the standard functionality of the CANalyzer with:
- Protocol-specific display and evaluation of CAN messages in the Trace Window
- Graphic display and evaluation of all online and offline participants on the network using the scanner
- The DeviceAccess dialog makes all functions available for communication via explicit message and offers the respective services, classes, and attributes for selection.
- The Heartbeat monitor allows the activation and monitoring of the heartbeat mechanism.
- The Explicit Polling function reads cyclical attributes from a device.
- The integrated dynamic database stores all procedures when establishing a connection. This is necessary in order to derive the meaning from an individual CAN message regarded in isolation, on one hand the identification allocation can occur dynamically (UCMM), on the other hand the data contents can have different meanings depending on the type of associated connection (I/O or explicit). For this reason, the pre-history of a connection must be known.
