The following table shows direct receive buffer memory access for float 32-bit objects, and unsigned and signed 32-bit
objects.

• Direct transmit buffer memory access to the CiA-405 Object
Use the TO or MOV instruction to write data to 'TPDO' (Un\G13000 to Un\G14023).
The initial setting of TPDO mapping is assigned to unsigned 16-bit objects. To change this setting, execute SDO or use
CANopen configuration software.
If 'TPDO' (Un\G13000 to Un\G14023) is mapped to TPDO of the object dictionary, data written to the buffer
memory area is reflected to the mapped object entry. The data is not reflected to the object entry that is not
mapped. If data is written to object entry using SDO, the data is not reflected to the buffer memory area.
