z Program 

explanation 

1.  The program first reset the SDO request message editing area and SDO response message 

editing area to 0. 

2.  When M0= On, CANopen master will send out SDO request message and write 0104Hex into 

index 2047, sub index 2 of the target equipment (at node address 02). If the communication is 

successful, the slave will return with the response message. 

3.  When M0 = On, CANopen master will send out request message only once. If you would like it to 

send out messages again, you will have to change the ReqID. 

4.  The messages returned from the target equipment are stored in D6000 ~ D6004. 

DVPCOPM-SL has three LED indicators and a digital display on it. POWER LED displays whether the power 

supply of DVPCOPM-SL is normal. RUN LED and ERR LED display the current operational status. The digital 

display shows the node address of DVPCOPM-SL and error messages from the slave.
