This document discusses different types of SCADA (Supervisory Control and Data Acquisition) systems and HMI/PLC (Human-Machine Interface/Programmable Logic Controller) systems. It describes traditional standalone SCADA systems used for pipelines and power distribution over long distances, as well as local control SCADA used within plant boundaries. It also discusses typical networked SCADA architectures, standalone and networked HMI/PLC systems, and issues with distributed control, computing, I/O, standards, and life cycle costs.

1. “Any way you want it”
The best of both worlds from Invensys

2. The two faces of SCADA
• Traditional SCADA for pipelines, power distribution or
anything that spans great distances
– Typical
– Stand-Alone
– Networked
• Local control SCADA for plant or unit operations or
any architecture that is within a defined boundary
– DCS
– PC based
– HMI / PLC

3. Only Invensys…
…delivering leading brand solutions, from
the production line to the bottom line.
