CANopen Communication Module DVPCOPM-SL l Command: Fixed to “ 01Hex ” . l 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 l node address: The node address of the target equipment on CANopen network. number. Range of ReqID: 00Hex ~ FFHex. l Total number of data: The total number of Emergency messages CANopen master receives. l Number of data stored: The latest number of Emergency messages CANopen master receives. (Every slave gives less than 5 messages.) Note:
l CANopen master can only send out 1 SDO, NMT or Emergency request message to one equipment at a time. l 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. 5.5 Application Examples In this section, we will illustrate how to compile a WPL program to send out SDO and NMT messages or read Emergency request messages. n Example I l Target: When M0 = On, read the content of index 2021, sub index 4 (i.e. actual output value of AC motor drive) in IFD9503.
