The Virtual Test Function evolves your plant into a VigilantPlant Efficient and uninterrupted production Virtual Test Function A complete PC-based control logic and HMI emulator that enables quick process changes while maintaining quality Typical situations Typical frustrations • A process unit and its instrumentation must be added that requires changes to graphics and control logic. • The schedule is always tight. Risks that lead to production delays or loss of quality must be kept be a minimum. • The need to install additional hardware and perform settings whenever changes are made. • Existing configuration data cannot be utilized because the configuration tools are incompatible. • Safety controllers are not handled in the same way. Traditional approach To do the debugging we’ll first need to locate some hardware that has the same configuration. No extra hardware/work necessary Getting one would be difficult. • An operator at an engineering station opens the CENTUM VP Virtual Test Function software. • No additional hardware or software is needed.

Efficient and uninterrupted production Traditional approach We found the hardware and now need to duplicate the currently running configuration, including the operator interface. The Virtual Test Function evolves your plant into a VigilantPlant No change to operator work environment This is getting complicated… The Virtual Test Function lets you use an existing configuration and choose which operator station to emulate. Have the same user interface and control logic, all using the same engineering configuration tool. Traditional approach Oh…! It looks like we’ll need to change our safety logic...
