Woodward recommends to configure the Node-IDs (parameter ╚═▷ 8950 ) for units, which
participate in load sharing, as low as possible to facilitate a fast establishing of
communication.
7.7.1 Load Share via CAN
Bus load
The bus load increases with the number of units participating in load sharing.
The following parameters affect the bus load:
• Number of CAN participants •
• Baud rate •
• Transfer rate of load share messages •
• Transfer rate of visualization protocols •
We recommend to consider whether all data has to be sent on the CAN bus when
planning the CAN bus. It is also possible to send visualization data via RS-485 for
example.
Measures to reduce the bus load
If you need to reduce the bus load of the load share CAN bus, the following methods may
be used:
• Increase the baud rate (parameter ╚═▷ 3156 ) under consideration of the bus length •
(refer to ╚═▷ “3.4.4 CAN Bus Interfaces” ).
• Increase time of the transfer rate of the load share message (parameter ╚═▷ 9921 ). •
• Increase time of the transfer rate of the visualization message, i.e. the event timer •
(parameter ╚═▷ 9604 ).
• Disable the transmission visualization data on the CAN bus and use the RS-485 •
interface to transmit visualization data.
• Disable SYNC message (parameter ╚═▷ 9100 ) and/or TIME message (parameter ╚═▷ •
9101 ) and/or the producer heartbeat time SYNC message (parameter ╚═▷ 9120 ), if
possible.
