The methodology of carrying out a migration or conversion project plays a very important role, because as we well know, shutting down a process to change the entire control system is often not possible. That is why this methodology allows this to take place orderly and safely.
3-Phases methodology
The methodology of how to carry out a migration or conversion project plays a very important role, because as we well know, stopping a process to change the entire control system is often not possible, due to industries where the operation never stops. That is why this methodology can greatly support us to be efficient in these projects.
1
PHASE
Consoles / HMI
- Replacement of operating consoles
- Installation of workstations running FTview
- Graphics update using face-plate libraries
- Connectivity to old system control network
2
PHASE
I/O modules
- Replace I/O from DCS for new I/O modules
- Interface between new remote I/O with the current control system network
- Old control system interacts with new I/O modules
3
PHASE
Processors
- The old DCS program is translated to the new system with similar add-on functions
- Functionality, network tests and simulations are run
- Control units are replaced according to the system configuration until the entire network is completed with the new PlantPAx platform
