3 — CANopen COMMUNICATIONS
Models 3140 / 3141 adhere to the industry standard CANopen communication protocol and thus will
easily connect into many CAN systems, including those using the Curtis AC and Vehicle System controllers
(such as Models F2A, 1234/36/38, 1298, 1310, and enGage VII). Any CANopen-compatible master can be
programmed to control Models 3140 / 3141.
MINIMUM STATE MACHINE
Models 3140 / 3141 will run the CANopen minimum state machine as dened by CiA. e CANopen
minimum state machine has four dened states: Initialization, Pre-Operational, Operational, and Stopped.
When Models 3140 / 3141 power up, they goes to the Initialization state; this is also known as the Boot-up
state. No CAN communications from Models 3140 / 3141 are transmitted in this state although Models 3140/
3141 listen to the CANbus. When Models 3140 / 3141 have completed their startup and self-tests, they issue
an initialization heartbeat message and automatically go to the Pre-Operational state.
In the Pre-Operational state, the 3140/3141 can receive and respond to SDOs and NMT commands, and will
send its heartbeat. It will not receive or send PDOs. Aer receiving an Operational State NMT command,
the 3140 / 3141 will enter the Operational state (full normal operation).
In the Operational state, Models 3140 / 3141 will start receiving and responding to PDOs and process all
other necessary CANopen messages.
BAUD RATES
Models 3140 / 3141 will run at one of seven selectable baud rates: 20kbps, 50kbps, 125 kbps, 250 kbps,
500 kbps, 800 kbps, and 1 Mbps.
e baud rate can be changed by an SDO. Changes in the baud rate require an NMT reset to make the new
rate active.
NODE ADDRESSES
e node address of the Model s 3140/3141 can be 1 to 127 and is used by CANopen to route messages to
Models 3140 / 3141 and to denote messages from Models 3140 / 3141. e node address is part of the COB-
ID and therefore also plays a part in message priority and bus arbitration.
Changes to the node address require an NMT reset or power-cycle.
