MasterBus – CANopen Interface / EN
5 MasterBus Event data to CANopen network
Your CANopen devices can react on Events in the
MasterBus network. The CANopen interface will
broadcast this data on the CANopen network. An
event PDO is transmitted containing all the 8 Event
states, each as a single data byte. Any MasterBus
product with Events can be configured to transmit an
Event to the CANopen interface. The CANopen
interface has 8 event targets; named Event target 1
to 8.
Transmit Event PDO
Once the “Send Event PDO” option is checked the
Interface will transmit a dedicated PDO with the data
of 8 events. This PDO will be transmitted periodically
and upon changes of the events.
COB-ID
Select the COB-ID for the Event PDO.
Example:
If you want a CANopen product to react on an empty
battery event of your MasterShunt battery monitor.
Select the following configuration:
In the MasterShunt configure one event.
Event source: Battery low
Event target: CANopen Interface
Event command: Event target 1
Event data: Copy
In the CANopen interface check the “Send
Event PDO” option and set the COB-ID for
the broadcast message.
Make sure your CANopen device listens to this
broadcast. An event PDO will be transmitted
periodically and when new events are received from
MasterBus.
The Event PDO consists of 8 bytes each
representing an Event state. 0x00 indicates OFF,
0x01 indicated ON, 0x02 indicates Alarm and 0xFF
indicates Not Applicable / Not initialized.
