2.9.2 Operation Phases

If a Frame Application requests available functions from the DTM (GetFunctions()), it passes the operation phase, which can be used by a DTM to adapt the availability of functions and the appearance of the user interface.

There are five operation phases:

• Engineering
  Planning and configuring of a plant,
  no online access to the plant
• Commissioning, workshop
  Installing the plant and the devices,
  Scanning the network to verify a planned network,
  Downloading project data into the plant,
  Programming, diagnosis of the devices,
  Adjusting parameters
• Runtime
  The plant is completely commissioned and running.
  Very restricted access to configuration and parameterization data.
  Scan to verify the network
  Replacing defect devices.
  Reading process values and diagnosis information.
• Service
  This operation phase is used for service tool Frame Applications.
  Scan to create a topology. Scan to verify a network. All service related operations. Unrestricted access to the device.
• Not supported
  The application doesn’t support the operation phases defined above.
  A DTM must offer all functions if the Frame Application passes "not supported".

The following table describes the usage of operation phases in different Frame Application types.

For example the DTM allows the maintenance actor during commissioning phase the complete online parameterization, but during runtime phase it doesn’t allow it or it allows it only for some of its parameters
