SCADA software is an integrated development environement which allows creation of SCADA HMI applications. Several SCADA software from various manufacturers are available, with significant differences in price and performance. The choice of the SCADA software most suitable for the application to be developed depends on several factors, as well as personal preferences, but is generally based on the complexity of the project, the required performances, any constraints imposed by the client and the available budget.
You should also consider the learning time, which is usually higher in case of a more complex SCADA software. As a general rule, the choice of a complex SCADA software is justified when the project involves a large and high-cost plant, for which software cost and learning time are no longer relevant. in the case of small-to-medium projects with a limited budget, it is advisable to move towards SCADA software that have a lower cost and require a shorter learning time.
All SCADA software, regardless of complexity, must however have common features regarding the following topics:
