“Data 1” shows the data transfer process from PROFIBUS to CAN; “Data 2” shows the data transfer process
from CAN to PROFIBUS.
The gateway runs in CANopen network independently, and transmits read/write commands of CANopen
parameters periodically according object dictionary, also transmits and receives PDO commands. When receiving
I/O request from PROFIBUS DP, the gateway will instantly respond with the latest CANopen data to realize the
matching of network speed. This is asynchronous mode.
TPDO and RPDO applies producer/consumer mode, and often be used in the occasion with high requirement
about speed; Upload SDO and Download SDO applies client/server mode, the mode can guarantee safety of data,
and often be used in the occasion with low requirement about speed.
