Unimplemented
Protocol for CAN-Based Communication
GC1100 genset controller implement a CAN-based protocol that can be used for reading the
measurement values, status of alarms and derived computations (such as cumulative power), as well
as for sending mode change and start-stop commands to the controller. Details of the communication
protocol are as described below
.
13.1
Connection Details
Baud rate used for communication is 250 kbps. The ID of the controller is fixed to 0x01. ID scheme for
CAN communication is Standard ID (not extended ID). Packet size used for communication is 8 bytes.
13.2
Structure of Communication
The controller continuously broadcasts measurement values, status of alarms/commands and derived
computations. Additionally, a set of commands can be sent to the controller. Response to the
commands is a part of the data that is broadcasted.
shows the structure of the broadcasted
message.
