6.11 Add Device Net Module
Comm
unication between a DVC5/7/10 Master controller
and a CAN Bus Device Net module is possible using the
Programming Tool. To communicate with a CAN Bus
Device Net device first add a DNET icon into your
project by right clicking in the project window and
selecting the Add Device Net module option from the
popup menu. Next, double click the DNET icon to bring
up the Device Net module window as shown. Using this
window you define the variable names used to send or
receive information from the Device Net module with the
specified MAC ID.
A brief explanation follows that will help explain how
communication is accomplished between the DVC5/7/10
and a Device Net module. The DVC BIOS uses the
explicit message feature of the Device Net protocol.
Each CAN Bus message has an eight byte data field. The first byte of which is the explicit message header.
The other 7 bytes contain the actual data. Messages of more than 7 bytes will take multiple messages to be
transmitted. Each message uses the header to identify the part of the message being received. Your
application will not see the header byte but will have to assemble multiple bytes into application variables where
needed.
Within the Device Net Module window are several fields. The Name field identifies the device. It is the prefix to
reference consume and produce variables. The MAC ID field represents the CAN Bus identifier for the device.
