8 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.
