Chapter 16 PLC Function ApplicationsC2000 Plus

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 D2013+n*100). This also
illustrates how the master can handle these tasks through read/write operations in the special
D area.
Furthermore, it should be noted that the remote I/O of PDO2 can obtain the slave device's current
DI and AI status, and can also control the slave device's DO and AO status. Nevertheless, after
introducing a fully automatic mapping special D, the C2000 Plus CANopen master also provides
additional information refreshes. For instance, while in speed mode, acceleration/deceleration
settings may have been refreshed. The special D therefore also stores some seldom-used real-time
information, and these commands can be refreshed using the CANFLS command. The following is
the C2000 Plus's current CANopen master data conversion area, which has a range of
D2001+100*n–D2033+100*n, as shown below:
1. The range of n is 0–7
2. ●Indicates PDOTX, ▲Indicates PDORX; unmarked special D can be refreshed using the
CANFLS command
