CANopen Device Monitor
Overview
The CANopen Device Monitor is a tool for the graphical inspection and configuration of CANopen devices in a CANopen network. The embedded scripting ability makes it possible to access the implemented CANopen services and to write test or control applications with a minimum of effort.
The information on how to display the device's object dictionary is obtained from the EDS (electronic data sheet) file of the device or can be scanned from the device directly. Special device configurations can be loaded, stored and scanned from DCF (device configuration file) files. The CANopen Device Monitor supports the XML-based device descriptions files compliant to CiA 311.
Description
The program's graphical user interface consists of:
- A hierarchical tree representation of the object dictionary
- An action field
- An optional command console interface and
- Several tabs
Besides that the CANopen Device Monitor provides function to scan of the object dictionary of the connected devices, to store and restore their parameters and to log the CAN communication. Displaying all implemented objects as a tree facilitates the configuration by hand. It is is divided into the following segments:
- Communication profile
- Manufacturer-specific objects
- Up to eight device profiles are supported
The tab action is used for reading and writing device objects with CANopen SDO transfer messages. Supported standard actions are available for reading/writing and incrementing/decrementing of a device object. Values of manually configured device objects can be stored to a file and reloaded into the device.
The NMT tab makes several fields available for the execution of NMT services like "Start All", "Start Node", "Preop All", "Preop Node" and "Scan Network".
Under the tab-set description an object description of the currently selected object in the object tree is shown.
Additional tabs are available for graphical representations of CAN data and can be defined by the user. With the console an interactive access to the CANopen network is possible by using commands for SDO/PDO transfers, network management services, Heartbeat and Node guarding, Time stamp and Sync.
Through the scripting language all implemented CANopen communication services are available for test and control applications.
Extensions to control drives according to CiA 402, a CANopen-Safety-Plugin (CiA 304) and as well as a LSS-module (CiA 305) are available, too.
Port GmbH can perform special adoptions to the GUI or behavior to meet CANopen device characteristics for service or assembly testing.
CANopen Configuration Manager
Overview
Large CANopen networks with several devices and a multiplicity of inputs/outputs can have a complexity, which is hard to manage without powerful tools. The CANopen Configuration Manager is such a tool that simplifies the configuration of CANopen networks. Using the CANopen Configuration Manager connections between devices and their configuration settings can be configured convenient. So the PDO linking is simplified enormously.
Description
Each network is managed as a project within the CANopen Configuration Manager. Devices can be added to a network via its EDS file or a network scan. Configuration of PDO linking is done by simply marking the objects shown in the table view. Internals of the CANopen protocol are hidden from the user and display occurs application-specific. Writing the configuration of the mapping values is of course possible. The program ensures consistency of project settings and device settings.
The following files are generated after completion of the configuration:
- DCF files of all devices
- Concise DCF files
- Project documentation in HTML format
- IEC 61131 variable list for CANopen-PLCs.
When the computer is connected via a CAN interface to the network the complete configuration or only changes of a single node can be sent directly to the devices on the network. Similarly it is possible to read the configuration of a node or even a complete network.
Advantages
- Simplified PDO linking
- Consistency of the configuration throughout the network
- Direct parameter download possible
- Support of CANopen-PLCs
CAN-Interfaces for CANopen Device Monitor and CANopen Configuration Manager
The usage of these software tools requires a CAN interface. CAN interfaces are currently available for USB, ISA, PCI, parallel port, serial port and PC-104 or an Ethernet interface like the Port's standalone CAN-Server EtherCAN or IGW/900.
