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.

Do we have a
spare?

• An operator at an engineering station opens
the CENTUM VP Virtual Test Function software.
• No additional hardware or software is needed.
