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.
