Table 3: Communication interface for RT VLS. are also compatible with LabVIEW software, especially when incorporating GUIs and data visualization windows for the simulation. The economical aspect of the RT simulation tools depends mostly on the objectives and preferences of the educational institution. The initial investment for entry-level equipment could be expensive; therefore, it is important to define the current and future application purposes before acquiring specialized hardware and software. This equipment could also be used to solve industrial problems. Table 4 indicates the approximate pricing of many of these simulation tools; the pricing information was obtained through official websites and available catalogs. RT is not only defined by the simulation processing time; it is also is connected with the experimental hardware and software representation of the solution times of each subsystem and the precision of the real-time results. The minimum processing time that could be achieved depends on the manufacturer of the RT system. Table 4 is added to specify the simulation platforms that allow for long-distance manipulation in the RT system.
