CAN-OPC UA Server
OPC UA Server for Mapping CAN Frames as Objects
Powerful and Resource Efficient
Scalable, high-performance and resource-efficient OPC UA server
Platform-independent and secure data exchange for CAN fieldbus devices
Implemented as a Windows® service it can be executed without an active user
Supports Classical CAN as well as CAN FD (Flexible Data Rate)
Fully Configurable and Flexible
Customizable OPC variables with bit-exact length/position in CAN data
Highly configurable by adding permissions, descriptions, units etc.
Adaptable to the structure of your CAN network topology
High Compatibility
Supported by any esd CAN interface with Windows driver support
Integration Support on Request
• esd supports your integration and development process
• Extended support is available
Linking OPC UA and CAN
Every CAN frame is mapped to one or more OPC UA variables by defined CAN ID, bit position and bit length together with data conversion rules for data types (Boolean, SByte, Byte, Int16, UInt16, Int32, UInt32, etc.).
Additional options for structure and accessibility are provided by adding groups, enumerations, and properties, to define the OPC UA variables.
Easy Configuration
Easy-to-use configuration tool for settings, mapping, and logging. Mapping is done via a CSV file, which can be easily edited with a text editor or most spreadsheet programs.
Input Data
The OPC variable’s data, including additional information about last received CAN message and variable state, is updated on each reading operation.
Output Data
Changing the OPC variable’s data can be configured to either directly trigger the related CAN message or to store the information to be send on demand.
Security
CAN-OPC UA Server für Windows supports a fully integrated encryption for Basic128Rsa15, Basic256 and Basic256Sha256 protocols.
Access Control
Customizable read/write permissions are defined by variable and client. Authentication support for anonymous and authenticated access.
High Compliance
The OPC server implementation was tested to be compliant with the OPC UA specification 1.3 (‘Micro Embedded Device Server Profile’, ‘SecurityPolicy-Basic256Sha256’) with the UACTT V1.3.
