ModbusView 1.4

ModbusView is an easy to use program that monitors and simulates Modbus communications on your PC. It enables your PC to act as both a modbus master and a slave device making it easy for you to simulate the action of your HMI machine, instruments, PLCs etc

Modbus is probably the most widely used protocol in process control industries today. Modbus allows serial communication to occur between slave devices such as Programmable Logic Controllers (PLC’s) and Instrumentation and Master devices such as computers or Digital Control Systems (DCS’s). The Modbus protocol has two basic forms. The RTU or Binary form and the ASCII form. In RTU or binary form all the bytes transmitted in binary a binary format. Hence the protocol is more efficient and faster. ASCII on the other hand all the bytes are transmitted in the ASCII characters ‘0-9’ and ‘A-F’.
