SOFTWARE
The Scada "Supervisory Control And Data Acquisition" system offered by Samac, the result of twenty years of experience, was entirely developed and is constantly updated using the latest technology on the market. The search for a continuously evolving standard that will also last over time, without being bound to third-party architectures or dedicated hardware compatible with proprietary busses or hard to procure in the future, has led us to use the following development packages:
  • Microsoft Visual Studio 2015 development environment
  • Microsoft C# development language
  • framework used 4.6
  • Microsoft SQL Server Express 2014 SP1 database

To make the system as open as possible to future developments, the supervisor has been implemented with a base package and "satellite” modules that can be integrated or not depending on the particular requirement.
