ModMultiSim is a new simulator that enables realistic simulation of multiple Modbus slaves in their environment.
ModMultiSim is a new simulator that enables realistic simulation of multiple Modbus slaves in their environment.
Users can connect their Modbus masters to ModMultiSim, instead of real Modbus slave devices, in order to test and configure the masters.
Using a simple control language users can simulate Modbus slaves measuring environment properties (eg flow rate), controlling the environment (eg opening valves), performing internal calculations (eg averages), and responding to Modbus commands from masters.
Users can also simulate environment changes (eg viscosity, flow) that are independent of a slave.
ModMultiSim displays the simulated environment and Modbus device registers as they change, and provides a trace of Modbus messages between slaves and masters.
It also has an online manual/troubleshoot/how-to facility.
Support is provided for network (Modbus/TCP) and serial (RTU/ASCII) interfaces.
The program will run on Microsoft Windows, Linux, Solaris and AIX.
A download of ModMultiSim is available for evaluation from the Wingpath website.
