■Protocol
1 Essentials
This document describes the CAN communication protocol for the CAN button operation panel. The key arrangement and corresponding key number (from A1 to B4 respectively) are shown in Figure 1:
|
Figure 1 Layout of CAN key panel |
2 CAN protocol
Refer to CAN2.0B
Baud rate：250kBit/s
Identifier：11位（Standard frame）
Description: All information in 8 bytes, BYTE0-BYTE 7, multibytes composition data low bytes first, high bytes behind
3 Send a message (key-press message)
Identifier: 0x007 (default)
Cycle: During power-up, the operation panel is always sent at a 100ms cycle, but immediately when the data changes (key status changes). data:
ID | Byte0 | Byte1 | Byte2 | Byte3 | Byte4 | Byte5 | Byte6 | Byte7 |
0x007 | Bit0:A1 Bit1:A2 Bit2:A3 Bit3:A4 | Bit0:B1 Bit1:B2 Bit2:B3 Bit3:B4 | 0xFF | 0xFF | 0xFF | 0xFF | 0xFF | 0xFF |
Description: If the value of the key when the key is pressed, the value of the key is 0.
4 Receive message (indicator light message)
Receive the controller data and control the corresponding indicator light according to the received data.
Identifier: 0x008 (default)
period: 100ms
Data: The indicator light receiving the CAN bus data control keys A1 to B4 is turned off
ID | Byte0 | Byte1 | Byte2 | Byte3 | Byte4 | Byte5 | Byte6 | Byte7 |
0x008 | Bit0:A1.1 Bit1:A1.2 Bit2:A1.3 Bit3Backlight control enabling Bit4:A2.1 Bit5:A2.2 Bit6:A2.3 Bit7:nc data | Bit0:A3.1 Bit1:A3.2 Bit2:A3.3 Bit3: No definition Bit4:A4.1 Bit5:A4.2 Bit6:A4.3 Bit7: No definition | Bit0:B1.1 Bit1:B1.2 Bit2:B1.3 Bit3:No definition Bit4:B2.1 Bit5:B2.2 Bit6:B2.3 Bit7: No definition | Bit0:B3.1 Bit1:B3.2 Bit2:B3.3 Bit3: No definition Bit4:B4.1 Bit5:B4.2 Bit6:B4.3 Bit7: No definition |
|
|
|
|
Note: 1. If the value of the corresponding bit in the data is equal to 1, the light is on; if the value is equal to 0, the light is out. 2. When the "backlight control enable" is 1, the "backlight control data" is effective, 1 backlight, 0 backlight out |

5 CAN key panel function setting
The communication node number and port rate of the CAN keyboard are set by the CAN bus data. When setting the CAN panel, the ID number is fixed to 0x7FF and the data format is as follows:
|
Figure 2 CAN panel function setting the data format |
The setting parameter (BCDE) exceeds 10 when setting the port rate is invalid; ID number (BCDE) exceeds 0x7FF when setting the standard frame; invalid ID number (BCDE) exceeds 0x1FFFFFFF when setting the extended frame; and invalid BCDE is not 0 or non-0 xFF when setting the power button function.
When the setting of node, port rate parameters and power button function meets the requirements, the parameters will take effect immediately after the setting.
6 Uploading of the system parameter information
In 1S before the panel is powered on (A1-2 indicator light), the CAN key panel sends the system parameter information through 0x7FE at a baud rate of 250 Kbit/s, the specific format is::
CAN Key-press panel system information
ID | Byte0 | Byte1 | Byte2 | Byte3 | Byte4 | Byte5 | Byte6 | Byte7 |
0x7FE | 0x20（order number） | Hardware version number (Low in front, high in back) | Software version number (Low in front, high in back) | 0xFF | 0xFF | 0xFF |
|
|
CAN the Key panel sets the parameter information
ID | Byte0 | Byte1 | Byte2 | Byte3 | Byte4 | Byte5 | Byte6 | Byte7 |
0x7FE | 0x21(order number) | Porter rate serial number (Low in front, high in back) | Received data ID1 type | Data ID1 (low before, high first)） |
|
|
|
|
Receiving data ID type value =0: standard frame format; =1: extended frame format. 0x7FF data is sent by serial number 0-1 for 100ms.
