have two device one of them Modbus master and another modbus slave.Modbus master working on windows PC. And it polling modbus read query and expects modbus response.
They communicate succesfully when slave powered on , than when I disconnected cable from Windows pc, and connect again they couldnt communicate never. ( Master changed port but slave couldnt close before port, or master couldnt close before port who is responsible for that i dont know)
Data packets like these and it flows forever: (1.40 device slave another master)
Why this happen? I did Modbus TCP Master-Slave this https://superuser.com/questions/1616670/modbus-tcp-master-slave configuration for slave side but it doesnt affect any thing. How can I solve this
