Buffer Memory Details: CANopen
Mode
Detailed Description of the Module
MELSEC-L Series – CANopen
Module ME3CAN1-L
3 – 15
3.5
Buffer Memory Details: CANopen
Mode
3.5.1
Data Exchange Control (Un\G20)
This buffer memory address allows the control of the OD and EMCY data exchange.
3.5.2
Function Mode (Un\G21)
The ME3CAN1-L chooses the communication function corresponding to the function mode set in the
buffer memory address 21.The possible settings are shown in the following table:
The buffer memory setting needs to be stored by Un\G22 bit 0 and afterwards to be restarted by Yn2
to make the new settings effective (Refer to section 3.5.3 and section 3.3.2).
Bit
Description
0–7
Reserved
8
Only in CANopen
modes: Data exchange mode setting (only OD data)
Bit = 0: No data exchange between buffer memory and CANopen
object dictionary
Bit = 1: Activate data exchange between buffer memory and CANopen
object dictionary
NOTES:
앫
The data will be also exchanged if this entire buffer memory address is set to 0 (default value).
앫
If the bit is set and the module is not in CANopen
state
Operational
, the PDO data will be exchanged after
going into
Operational
state.
9–11
Reserved
12
Data exchange status (only EMCY data)
Bit = 0: No data exchange between Emergency Message buffer memories and EMCY Receive Buffer
Bit = 1: Exchange data between Emergency Message buffer memories and EMCY Receive Buffer
For more information please refer to section 3.5.17
NOTE:
앫
The data will be also exchanged if this entire buffer memory address is set to 0 (default value).

Function Mode
Description
11
11 bit CAN-ID Layer 2 mode
This mode supports the 11 bit CAN-ID Layer 2 Message.
29
29 bit CAN-ID Layer 2 mode
This mode supports the 29 bit CAN-ID Layer 2 Message.
405
CANopen
405 mode
This mode supports the CANopen

405 IEC 61131-3 Program-
mable Device Profile.
Other value
—
All other settings will generate an error (in this case bit 6 in Un\G29 is
set (Refer to section 3.5.7).
Tab. 3-8:
Function mode setting in buffer memory address Un\G21
NOTE
During a restart, all Object Dictionary (OD) settings will be deleted when the CANopen
mode is
changed.
