Modbus TCP server accept TCP-IP commands from the external Nodbus client. External client in C/C++,C#, etc. can use SDK/ dll library to communicate with Modbus client that communicates with the server. Java external client can directly communicate with the Modbus library without a need for the dll. Modbus integration approach gives user detailed control of the measurement process. Modbus is a transactional Request/ Response protocol, so every single measurement needs to be requested. This can be an advantage or a drawback, depending on the application requirement. The advantage is a tight control of the timing of the measurement, so it can be synchronized with other actions. Disadvantage is a relatively slow rate of the measurement because of the overhead of the roundtrip for each measurement/transaction. Modbus server integration using SDK and dll library Modbus server integration using Java client.
