Programmable Modbus slave simulator

Wingpath has released a programmable Modbus slave simulator for use by system integrators and software developers. Master software can be connected to ModSlaveSim instead of the real slave device, and ModSlaveSim will provide a changing and responsive environment with which to test and configure the master.

Wingpath Software Development has released ModSlaveSim, a programmable Modbus slave simulator.
Master software can be connected to ModSlaveSim instead of the real slave device, and ModSlaveSim will provide a changing and responsive environment with which to test and configure the master.
ModSlaveSim will be of particular interest to system integrators and software developers, who need to develop systems before a slave device is producing real data in a live installation.
ModSlaveSim enables you to simulate not only the internal logic of a Modbus slave device, but also the environment of the device: the values it measures (temperatures, flow rates, etc.) and the equipment it controls (valves, motors, etc.).
Both serial (RTU and ASCII) and network (TCP) interfaces are supported, and the program will run on Windows, Linux, Solaris and AIX.
A free download of ModSlaveSim is available for evaluation from: http://www.wingpath.co.uk/modslavesim.php.
