CANopen Communication Module DVPCOPM-SL M0 ReqID = 01, Command = 01 Size = 04 Type = 01, MAC ID = 02 Index = 2021 Sub index = 04 END 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 read the contents in index 2021, sub index 4 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 4. The messages returned from the target equipment are stored in D6000 ~ D6005.
messages again, you will have to change the ReqID. Example II Target: When M0 turns OFF to ON, set the content in index 2047, sub index 2 (i.e. the control word of the target temperature) in IFD9503 to 0104Hex (i.e. 26.0°C). Please note that you have to write 0401Hex into D6255 of the PLC. DVP-PLC Operation Manual 35 MOV H0101 D6250 MOV H0004 D6251 MOV H0102 D6252 MOV H2021 D6253 MOV H0004 D6254
