Curtis 3140 Manual – Nov. 2016

1—INTRODUCTION

e Curtis Model 3140 CAN instrument is designed to display critical vehicle and motor controller data
on an easy-to-read and attractive LCD. e display includes three 10mm digits and six 5mm digits and all
digits are in 16-segment format to allow use of the full alpha numeric character set. Model 3140 integrates
seamlessly with Model F2A and other CANopen-based motor controllers.

e 3140 includes the following:

• Integrates seamlessly with Curtis Model F2A (and other CANopen-based motor controllers) thereby
reducing the amount of development work by the vehicle designer.

• Attractive xed-segment, transective LCD with 16-segment digits and informative icons allows
intuitive reading in all lighting conditions and battery-powered vehicle environments.

• Optional integral CAN termination resistor allows exibility in customer vehicle design.

• Industry standard 52mm panel cutout allows the use of exising panel/tool designs thereby lowering
development cost.

• Battery State-of-Charge (BSOC) can be calculated in the 3140 or sent to the 3140 by the Model F2A
(or equivalent CANopen-based motor controller).

• In addition to the 3 and 6 digit portions of the LCD, a percent symbol, wrench symbol, hourglass
icon and decimal point are also present which provides more comprehensive information about
vehicle status.

• Single unit operates from 24, 36, to 48 VDC allowing use on many models of battery-powered vehicles.

• Optional backlighting and LCD heater allow use in low-light and cold-store applications.

• Integrated 6-pin Mini-Universal MATE-N-LOCK connector allows for an easy and environmentally
protected connection.

• Environmentally protected (IP65 front, IP54 rear) to allow use in harsh environments.

• CE compliance, UL recognition and RoHS2 compliance ensure compatibility with global
regulatory standards.

CANopen Convenience

Model 3140 is CANopen compliant, responding to the
standard NMT, PDO and SDO communications as well
as the DS301 required identity and standard objects.
The Curtis CANopen extensions allow additional
features, such as OEM and User default congurations.
Model 3140 will receive a single SDO and respond with
a single SDO. ese SDO’s are xed, simplifying the
interface to a VCL-enabled device. All programmable
parameters and viewable values within the 3140 are
accessible via standard SDO transfer.

3 — CANopen COMMUNICATIONS

The Model 3140 adheres 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 the Model 3140.

MINIMUM STATE MACHINE

The Model 3140 will run the CANopen minimum state machine as defined by CiA. The CANopen minimum
state machine has four defined states: Initialization, Pre-Operational, Operational, and Stopped.

When the Model 3140 powers up, it goes to the Initialization state; this is also known as the Boot-up state. No

Transmit Boot-up

Pre-Operational

Operational

Communication

Stopped

CAN communications from the Model 3140 are transmitted in this state although the Model 3140 listens to
the CANbus. When the Model 3140 has completed its startup and self-tests, it issues an initialization heartbeat
message and automatically goes to the Pre-Operational state.

In the Pre-Operational state, the 3140 can receive and respond to SDOs and NMT commands, and will send
its heartbeat. It will not receive or send PDOs. After receiving an Operational State NMT command, the
3140 will enter the Operational state (full normal operation).

In the Operational state, the Model 3140 will start receiving and responding to PDOs and process all other
necessary CANopen messages.

BAUD RATES

The Model 3140 will run at one of seven selectable baud rates: 20kbps, 50kbps, 125 kbps, 250 kbps, 500 kbps,
800 kbps, and 1 Mbps.

The 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

The node address of the Model 3140 can be 1 to 127 and is used by CANopen to route messages to the Model
3140 and to denote messages from the Model 3140. The 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.

Curtis 3140 Manual – Nov. 2017

STANDARD MESSAGE IDENTIFIERS

The Model 3140 will produce—and respond to—the standard message types with the following CANopen
identifiers.

The 11-bit identification field is a fixed part of the CANopen specification called the Communication OBject
IDentification (COB-ID). This field is used for arbitration on the bus. The COB-ID with the lowest value gets
priority and wins arbitration. Consequently, NMT messages have the highest priority of the standard message
types, and the heartbeat has the lowest priority.

Message Type Message Identifier

NMT 0000 – 0x00

PDO-MISO 0011 – 0x03

PDO-MOSI 0100 – 0x04

SDO-MISO 1011 – 0x0B

SDO-MOSI 1100 – 0x0C

HEARTBEAT 1110 – 0x0E

The standard organization of the COB-ID puts the message type in the upper four bits, and the Node ID in the
bottom seven bits:

11 10 9 8 7 6 5 4 3 2 1

Message Type Node ID

NMT MESSAGES

NMT (Network Management Transmission) messages are the highest priority message available. The NMT
message puts the Model 3140 into one of the four defined states. These messages have 1 byte of data sent by the
master; the slave does not respond with any data to an NMT. The Model 3140 state value is transmitted with
each heartbeat message.

Value State

0x00 Initialization (or “boot-up”)

0x04 Stopped

0x05 Operational

0x7F Pre-Operational

The NMT message identifier consists of the standard message type (NMT)
in the top four bits; the bottom seven bits must be set to zero.

pg. 4

3 — CANopen COMMUNICATIONS

Curtis 3140 Manual – Nov. 2017

The first data byte of the NMT command is the command specifier:

Value Command Specifier

0x01 Enter the Operational state

0x02 Enter the Stopped state

0x80 Enter the Pre-Operational state

0x81 Reset 3140 (warm boot)

0x82 Reset the CANbus

The second byte of the NMT command defines whether this NMT is for all slaves on the bus (data byte = 00h)
or for a specific node (data byte = Node ID of the Model 3140).

HEARTBEAT MESSAGES

The heartbeat message is a very low priority message, periodically sent by each slave device on the bus. The
heartbeat message has a single byte of data and requires no response. Once the Model 3140 is in the Pre­Operational state, the next heartbeat will be issued and will continue until communication is stopped.

The heartbeat message has only one data byte. The top bit is reserved and should be set to zero. The bottom 7
bits hold the current NMT device state as defined previously.

LCD LAYOUT

The LCD layout is shown below. It features three large 16-segment characters, six small 16-segment characters,
an hourglass icon, percent icon, wrench (service) icon and a decimal point.

Curtis 3140 Manual – Nov. 2017

POWER-UP SEQUENCE

Upon power-up or transition from Pre-operational to Operational state, the 3140 will go through a three­second diagnostic sequence. e LCD will be blank for the rst second, then turn on all segments for one
second, then blank for one second. e LCD will show all asterisks for ve seconds aer the power up
sequence is complete, or whenever the NMT state is Operational but PDOs have not yet been received. is
sequence will be aborted if PDO message processing has been started (3140 commanded to Operational
state and PDO messages received).

EMERGENCY MESSAGE PROCESSING

Emergency messages are not supported on this product. e product is simple enough that there are no
errors.

PDO MESSAGE PROCESSING

When the Master sends a Slave device a PDO (PDO-RX, Master Out, Slave In), the Slave device will respond
with a corresponding PDO-RX within 16 milliseconds.

PDO1_RX

Byte 1 Command_Word Low Byte CAN object 0x3000

Byte 2 Command_Word High Byte CAN object 0x3000

Byte 3 Large_Text_Char_1 (leftmost) CAN object 0x3001, sub-index 0x01

Byte 6 Backlight percent CAN object 0x3005, sub-index 0x00

Byte 7 Hourmeter enable CAN object 0x3010, sub-index 0x01

Any data bytes in excess of seven will be ignored. If a byte is not present in the PDO message received, the
object mapped to that byte will not change as a result of the PDO reception.

Byte 1, bit 0 determines if the 3 large text characters displays the ASCII text sent in Bytes 3 – 5 or the internal
BSoC calculation. Byte 1, bits 1 – 2 command the 3 large text characters to be on, o or blinking. Byte 1, bit 3
determines if the 6 small text characters displays the ASCII text sent in PDO2_RX or the internal hourmeter.
Byte 1, bits 4 – 5 command the 6 small text characters to be on, o or blinking. See Table 1 for details.

BDI_CTR_empty: e “empty” parameter for the charge-tracking-reset curve, in mV per cell.

BDI_OCR: e open-circuit reset value, in mV per cell.

BDI_integration_time: e integration time, in minutes.

B+_nominal: e nominal B+ system voltage, in volts, e.g. 24, 36, 48.

can_baud_rate_struct_length: is parameter indicates the number of CAN ports that have baud rate

can_baud_rate: is parameter is enumerated as follows:

denitions.

Value Baud Rate

-2 20k

-1 50k

0 125k

1 250k

2 500k

3 800k

4 1M

can_node_id_struct_length: This parameter indicates the number of CAN ports that have Node ID

denitions.

can_node_id: 0-127 indicating the node ID of the display.

can_pdo_timeout_period: 0-32767 indicates the time in milliseconds that the last CAN-commanded

data will be displayed. If no PDO1_RX messages are received within this time, all icons
and the backlight will turn o, Hourmeter Enable will be set to zero (stopping the internal
hourmeter from counting), and the large text display will show “***” until the next
PDO1_RX message receipt. If the large text source is “BSoC”, then the large text display
will continue to show the internal BSoC calculation.
If no PDO2_RX messages are received within this time and the small text source is set for
“CAN”, the small text display will change to “******” until the next PDO2_RX message
receipt. Otherwise, the small text display will continue to show the internal hourmeter
value.
Note: If both PDOs time out, then the unit enters Pre-operational mode. When
this occurs, the display will go blank and the backlight will turn o.

P_User_1 ~ P_User_10: ese objects are 32-bit general purpose non-volatile objects. ese objects will be

stored in EEPROM if “save” is written to canopen_store_all_parameters.
