Elipse Modbus Simulator is a generator of random values for applications compatible with Modbus RTU and Modbus TCP protocols. In addition, it also allows receiving writing messages performed by these applications. This program can be downloaded at Elipse Software's website.
When Simulator starts, its working area opens, as shown on the next figure.
