CAN-OPC Server Data Sheet

CAN-OPC Server Data Sheet
OPC DA Server for the Controller Area Network (CAN)
• OPC Server compliant to OPC DA (Data Access) specification
3.0, 2.05a, 2.0 and 1.0a.
• Allows connecting most SCADA/HMI systems on the market
to CAN fieldbus devices
• OPC item data freely configurable: endianess and bit exact
length/position in CAN data
• Works with any esd CAN interface with Windows® driver
Configuration Based on Text File
CSV file (Comma Separated Values) to describe the OPC items and
the fieldbus configuration (CAN baud rate, ...) which can easily be
edited with a text editor or most spreadsheet software.
OPC Items
CAN data is mapped into OPC items or vice versa with bit
granularity by definition of CAN-ID, bit position, bit length and
endianess together with data conversion rules for the standard OPC
variable types (UI16, I32, ...) and access types (read/write).
Input Data / Read-only OPC Items
The OPC variable’s data is updated whenever a CAN message
matches the configuration.
Output Data / Write-only OPC Items
Changing the OPC variable’s data triggers sending the related CAN
message according to the configuration.
Sample Windows OPC Client Included
To quickly test the OPC server’s functionality/configuration. Lists all
OPC servers, allows to read/write variables etc. Additionally a
simple graphical plotter is included, e.g. to display some variable’s
Illustration 1
OPC item 'TestInt1' as output data for 'Maschine-1' sent in CAN-ID
0x200, OPC item 'TestInt3' as input data from 'Maschine-2' received
in CAN-ID 0x201 etc.
