The master station sends a SDO request message.
The slave station sends an SDO response message.
A: An AH500 series CPU module sends request information to the master station AH10COPM-5A.
B: The master station AH10COPM-5A sends the request information to target equipment.
C: The target equipment processes the request information, and sends response information to the
master station AH10COPM-5A.
D: The AH500 series CPU module received the response information (SDOs, NMT, and
emergencies).
