“Any way you want it”The best of both worlds from
Invensys
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
…delivering leading brand solutions, from the production line to the bottom line.
Only Invensys…
