zProgram explanation

1.The program first reset the SDO request message editing area and SDO response message editing area to 0.

2.When M0= On, CANopen master will send out SDO request message and write 0104Hex into index 2047, sub index 2 of the target equipment (at node address 02). If the communication is successful, the slave will return with the response message.

3.When M0 = On, CANopen master will send out request message only once. If you would like it to send out messages again, you will have to change the ReqID.

4.The messages returned from the target equipment are stored in D6000 ~ D6004.
