Component List Editor
8.2 Functionality of the Component List
8.2
Functionality of the Component List
Introduction
The component list offers a storage system for the following important runtime properties of
the measurement point in the PCS 7 OS and allows them to be edited:
● Measurement point name
● Measurement point type
● Area location
● Entry point picture
● Name of the block icon in the entry point picture
Generating the component list
The component list derives the project-specific data from the PCS 7 ES configuration in the
course of the AS-OS engineering ("Compile OS").
For measurement points entered by the user in the Component List Editor, the entry point
picture and the name of the block icon are generated (if they do not already exist) from the
calculation of the group display hierarchy of the Picture Tree Manager for the area. If the owner
is neither the user nor AS-OS engineering, the project-specific data is updated.
If a picture configuration exists already, the entry point picture is determined for the
"LoopInAlarm" function. If a block instance is in several pictures, the system selects one of the
pictures as the entry point picture. However, if you wish to designate a specific picture as the
entry point picture, you must change the entry point picture for the measurement point in the
Component List Editor.
The entries in the component list receive an owner which serves to establish the origin of the
data. The owners have the following properties:
● In the entries created by AS-OS engineering, they can change the entry point picture. These
entries have the owner "System ES".
● You can change and delete properties of the entries you yourself have created. These
entries have the owner "User".
Updating the entries in the component list
AS-OS engineering after editing the component list guarantees the update of entries. The
existing entries are deleted and newly created ones are assigned the "System ES" as the
owner. If the entry point picture resulted from calculation of the group display hierarchy, the
entry point picture is determined once again.
If another owner deletes a measurement point in the component list or renames the entry point
picture, the name of the previous measurement point or the original entry point picture remains
in the component list following the AS-OS engineering.
If you change the entry point picture to a module, you must also change the object name
accordingly. You must save the group display hierarchy again in the "Picture Tree Manager"
editor or load the project.
