Polymath is the programming software of ESA elettronica, developed in .NET technology with latest generation features. Equipped with a modern and complete interface, it offers a wide functionality range in step with the new requirements on the HMI market. The architecture of Polymath is extremely flexible as it allows to program all operator panels in the ESA range, as well as develop supervision solutions for small and medium plants. In this way, the user can pass easily from an application developed on HMI platform to one developed on PC platform and vice versa. Thanks to a very high number of communication protocols supported, with Polymath there are no longer limits to connectivity, both in industrial environments and towards the world of PCs. All of the most important communication buses in the industrial world are also available: Profibus, DeviceNet, Can and Profinet. Polymath allows easy and intuitive programming, which allows optimisation in terms of time and effectiveness both in the development phase and in the execution of the project. Among the advantages offered by Polymath there is, for example, the possibility to import the variables directly from the PLC database, thus avoiding useless time-loss for filling in the project variable table. Within Polymath the user can also make use of import and export of recipes, alarms, translations and variables in standard Excel format tools. In the case of applications developed in several languages, Polymath integrates a dictionary for automatic translation of the terms.
