meantime, you should check if the data in Emergency message are correct.
 Node ID: The node address of the target equipment on CANopen network.
 Total number of data: The total number of Emergency messages CANopen master receives
from the slave.
 Number of data stored: The latest number of Emergency messages CANopen master
receives from the slave. (5 messages at most)
 The data in D6004-D6007 are the content of Emergency 1 and every Emergency message
consists of 8 bytes of data.
The data format of Emergency message on CAN bus is shown below. Datum 0~ datum 7 in
Emergency response message correspond to byte 0~ byte 7 respectively
