Scope of functions
The functions that can be used with the IEA include:
● Standardized plant libraries with tested process tag types and models
● Import of plant data (e.g. process tag lists or I/O lists) from the higher-level CAD/CAE
environment
● Automatic generation of the AS configuration based on imported process tag lists and
process tag types (CMTs cannot be used).
– Creation of the plant hierarchy
– Editing stored process tags
● Automatic derivation of the OS picture hierarchy, automatic connection of blocks, and
positioning within pictures
● Automatic creation of an OS archive
● Creation of individual process objects using appropriate graphical tools such as CFC and
SFC
● Export of optimized parameters back to the CAD/CAE environment
Working with the import / export assistant (IEA)
The Import Export Assistant offers the convenient option of creating function charts using
process tag types and models. You also are given the option of exporting the files created in
PCS 7 (for plant documentation, for example), editing them in Excel, and then importing them
back into PCS 7.
The following procedure should be followed when creating process tag types and models:
● Create the process tag types and test them to ensure that they function correctly. Changes
made at a later cost time.
● All workers in a multiproject should use the same process tag types. Each worker should
be assigned a name band for IEA files he creates.
This allows the files to be easily entered into the multiproject. The workers should be able
to use the process tag type for import, but should not be allowed to change the template.
Changes should always be made from a central location, and then made available to the
workers.
● The IEA should be only be used during the configuration phase. Changes to parameters
and interconnections in the charts should be made during the FAT (Factory Acceptance
Test) or during commissioning.
Since users make changes in the charts and not in the IEA files, any new IEA import may
overwrite the changes.
● During the FAT and subsequently while the plant is in process mode, the process object
view offers the possibility of editing charts created via the IEA in tabular form. You also
have the option here of exporting and importing (see also section:"Managing process tag
types with the process object view (Page 179)").
