Hi Experts, Anyone who has experiment on setting up DNP3 serial communication between TM 1703 and SEL 311L relays Pls help me! I have a such project in which the RTU has 1 SM 2551 card and was configured as DNP master (firmware: DNPMA0) to communicate with SEL relay. In addition, the RTU has also 1 SM2556 plays a role as 104 slave to send data to control center. - I have configured SEL relays and make sure that the relay already sent DNP data outside (picture 1). - The DNP data getting from SEL relays are mapped in to IEC 104 datapoint (picture 2). - But the IEC 104 datapoints have wrong values (It seems that the problem lays on mapping scheme) as point number 215 on picture 3. I have once more confused matter on DNP cyclic polling data parameter in OPM (picture 4). As far as I known, arccording to DNP 3 protocol, object and variation are 2 individual fields, but in OPM, they are combined together, So I don't know how to fill the cell Object variation. I attach here picture 1, 2, 3, 4. Pls help me to resolve my problem. Rgds, Tuan, AttachmentDNP_problem.zip (353 Downloads) |
