b. In the open Contents diagram click File > Print, in the Print dialog set the
options to print the Contents and the Diagrams and then finish the print
action.
If plant modelling to the level of process functions has been done before, steps
Step 1 and Step 2 have already been done.
In Step 11 the I/O Signal objects are assumed to exist already:
• Either the I/O Signal objects have been instantiated before with own object
types like shown in Process Object Type with Signals on page 504.
• Or, if you use the standard object type libraries of AC 800M you have created,
parameterized and assigned the needed I/O Signal objects for functional
planning in a separate steps, for example with an own Bulk Data Management
worksheet.
As an alternative to Step 3 and Step 4 you can create the required instances of the
Function Component object types by editing in Function Designer,
using Insert > Symbol in or using Drag and Drop of an object type from the
corresponding library on to the Function Diagram. See the control loop example in
Working with a Function Diagram on page 42. The instances are created in
Functional Structure below the object that holds the Function Diagram and
represents the process function.
Depending on the project requirements also inserting and connecting Diagram
Variables can be done using a Bulk Data Management worksheet. Even complete
Function diagrams can be created using a worksheet configured accordingly.
How to configure Bulk Data management worksheets in general is described in
System 800xA Engineering, Engineering Studio (3BDS011223*).
Global Variable and Communication Variables
The global variable facilitates communication between restored diagrams (created
upto System Version 5.0 SP2).
The communication variable facilitates communication between:
• Newly created Function Diagrams in System Version 5.1 or later.
• A restored diagram (created upto System Version 5.0 SP2) and a newly created
diagram in System Version 5.1 or later.
