Buffer Memory Details: CANopen
Mode
Detailed Description of the Module
MELSEC-L Series – CANopen
Module ME3CAN1-L
3 – 29
Direct transmit buffer memory access to the CiA
-405 Object
Use a TO or MOV instruction to write data to the following locations.
The default TPDO mapping is assigned to unsigned 16 bit objects. To change this setting, please use
the SDO command in the CIF (command interface, refer to sections 4.6.5 and 5.1) or CANopen
net-
work configuration software.
●
Signed and unsigned 8 bit object
NOTE
Data written to the buffer memory will only be copied into the Object Dictionary (OD) when they
are mapped into a PDO.
Example: Un\G13000 is assigned to the OD Indexes/Sub-indexes A240

Indexes/Sub-indexes.
