Complete migration of the control-command system

Customer: Solvay

Segment: Chemicals

Location: Chalampé, France

Launched in 2011 and scheduled to last for a dozen years, it is one of the largest projects launched in the French chemical industry in recent years. A major project to replace the entire control system at this huge 125-hectare site, which produces 40% of the world's demand for "Nylon salt", the base compound for the manufacture of Nylon.


Solvay has migrated the entire current control command and control system (Emerson RS3) to the Siemens PCS 7 solution. To meet this challenge, Siemens joined forces with Actemium, which contributed its know-how on migration methods and its skills in retroanalysis and system configuration.


Technical solution:

Implementation of a mixed supervision capable of controlling the RS3 system and the PCS7 system

Replacing processors

System migration

Segment: Chemicals

Location: France

Among other important investments to ensure its future, our client has undertaken the conversion of its TDI workshop into a new product manufacturing workshop: HDI.


Actemium's job was to migrate the RS3 control and command system to a Delta V Series S DCS. The project represents a volume of 6,900 hours of studies and work.


Technical solution: 

Activity: control command

Technologies used: Emerson Rosemount, System 3, Emerson Delta V series S, Modbus communication with APS Triconex and APS Siemens PCS7 (Safety Matrix)
