D6024~ D6031
 Command: Fixed to "01Hex".
 ReqID: The request ID. Whenever an Emergency message is sent out, the message will be given a ReqID for the
CANopen master to identify. For the next Emergency message to be sent out, you have to change the ID number.
Range of ReqID: 00Hex ~ FFHex.
 MAC ID: The node address of the target equipment on CANopen network.
 Total number of data: The total number of Emergency messages CANopen master receives.
 Number of data stored: The latest number of Emergency messages CANopen master receives. (Every slave gives
less than 5 messages.)
Note:
 CANopen master can only send out 1 SDO, NMT or Emergency request message to one piece of equipment at a
time.
 When you use WPL program to send out SDO, NMT or Emergency request messages, we recommend you clear
the "request message editing area" and "response message editing area" to 0.
