z  Command: Fixed to “01Hex”. 

z  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. 

z  MAC ID: The node address of the target equipment on CANopen network. 

z  Total number of data: The total number of Emergency messages CANopen master receives. 

z  Number of data stored: The latest number of Emergency messages CANopen master receives. (Every slave 

gives less than 5 messages.) 

Note: 

z  CANopen master can only send out 1 SDO, NMT or Emergency request message to one equipment at a 

time. 

z  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.
