Line 129:
Increasingly, and ironically, DCS are becoming centralised at plant level, with the ability to log into the remote equipment. This enables operator to control both at enterprise level ( macro ) and at the equipment level (micro) both within and outside the plant as physical ___location due to interconnectivity primarily due to wireless and remote access has shrunk.
As wireless protocols are developed and refined, DCS increasingly includes wireless communication. DCS controllers are now often equipped with embedded servers and provide on-the-go web access. Whether DCS will lead Industrial Internet of Things (IIOT) or borrow key elements from remains to be established.
Many vendors provide the option of a mobile HMI, ready for both [[Android (operating system)|Android]] and [[iOS]]. With these interfaces, the threat of security breaches and possible damage to plant and process are now very real.
