Because usage requires only simple to open the corresponding PDO, where TXPDO
employs D2034+100*n settings and RXPDO employs D2067+100*n settings.
These two special D areas are defined as follows:
PDO2 PDO1
Default definition Remote I/O Speed

En: indicates whether PDO is used
Length: indicates mapping of several variables
In a simple example, if we wish to control a CP2000 slave device and cause it to operate in
speed mode, we only have to make the following settings:
D2034+100*n =000Ah

Switch the PLC to Run after completing settings. Now wait for successful initialization of
CANopen (M1059 = 1 and M1061 = 0), and then initiate CANopen memory mapping (M1034 = 1).
The control word and frequency command will now automatically refresh to the corresponding
slave device (D2008+n*100 and D2012+n*100), and the slave device's status word and currently
frequency will also be automatically sent back to the master station (D2009+n*100 and
