SCADA is an acronym for Supervisory Control and Data Acquisition. Supervisory Control is the ability to take action on remote locations through the use of various controls and mechanisms like opening and closing a valve, unlocking security doors. The Data Acquisition part covers the ability to retrieve key pieces of information from remote devices like weather information from remote sensors, real time traffic data and levels in a fuel tank. There are similarities between M2M that is machine to machine communication and SCADA. M2M solutions generally encompass doing one of the two things covered by SCADA term. The difference only comes from what is done with the information derived from two different solutions. SCADA solutions are primarily used by Operations and Field Service and M2M solutions are used in industries like IT, retail, finance and the data is further introduced to key systems like ERP and CRM. Also. SCADS is heavily linked to connecting to devices using some unique protocols like ModBus, and uses ports that are not common in many areas of the IT world like RS-485. The vast majority of M2M solutions use SCADA as their basis of offerings. Also M2M solutions are easier to understand and explain than SCADA and their information is hosted in cloud-based solutions.
