Alican Tarım Posted October 17, 2020 Report Share Posted October 17, 2020 Good afternoon, I have a V1040 Master Plc and I want to communicate more than 2 slave devices (v700,v570,v430 etc.) I tried Modbus TCP-IP Master-Slave and UDP Master-Slave examples, but I could not communicate at the same time. While doing a sample with UDP, when I send data from Slave1, it writes to the Master MI20. Likewise, when I send data from Slave2, it writes to the MASTER MI20. When I send data from Slave1 that I want, it will write to Master MI20. If I send data from Slave2, It will write to Master MI30 For example, I want to write between MI100 and MI130, between ML100 and ML120 from Master PLC to Slave1 PLC. I want to write between MI200 and MI230, between ML200 and ML220 from Master PLC to Slave2 PLC. And also, I want to read between MI500 and MI530, between ML500 and ML520 from Slave1 PLC to Master PLC. I want to read betweeen MI500 and MI530, between ML500 and ML520 from Slave2 PLC to Master PLC. I would be very happy, If you could help. If you want, I can send the application by e-mail. Have a nice day. Quote Link to comment Share on other sites More sharing options...
