Hi Experts,
I am very new to industrial automation domain. I have a couple of question. I thankful to all if you can clarify some of the things
Our customer has set of devices which are used in the industry. Currently they support Modbus and Hart communication. We are using OPC server and a client Application which is also developed by our customer. Currently the both OPC server and Client lack in Multidrop connection. We are yet to provide support for Multidrop network.
I am in the position to design the system to support Multidrop connection. All I know is, we can specify the port address in the modbus protocol before sending any message and also the device will reply back with the same port address. I am more concerned about data collison. Suppose say, I connected to two devices (Device 1 and Device
2) through multi drop connection.Now My client application wants to trend the data received from Device
1 and Device 2. Is it possible? Are they any possible data collison..Please let me know if you need more information..
Regards,
Krish
