The functions that you can run with system-wide engineering and whose device-to- device relationships are managed by the ES include the following: • Copying a complete subsystem that includes charts for the AS and pictures for the OS. • Deleting a subsystem whereby all the objects belonging to the subsystem are deleted. • Moving a subsystem to other devices (AS and OS). Note In the case of AS-AS device-to-device connections, you have to image them on CFBs (communication function blocks) and then connect these via a communications channel. Copying a SIMATIC station or an S7 program: In the Components View you can copy complete SIMATIC stations or finished S7 programs. Below are a few notes on this: • Copying a SIMATIC station (CPU) in the project: When copying a SIMATIC station, the hardware properties of the station are copied 1:1. In the associated program folder all interconnections to global operands and runtime groups, and the interconnections between the charts are retained. The station is given a new name. The technological hierarchy is retained. All charts affected by the copying process are now exist twice in the technological hierarchy (original and copy with different names). • Copying a SIMATIC station (CPU) project to project: When copying a SIMATIC station from one project to another project, the hardware properties of the station are copied 1:1. In the associated program folder all interconnections to global operands and runtime groups, and the interconnections between the charts are retained. The station is given a new name. The technological hierarchy of the copied station is also built up in the target project. If the station in the source project has relationships to the TH, then these are reestablished in the target project (set up of a TH or use of a TH with the same name in the target project). • Copying an S7 program in the project or from project to project: When copying a program folder, all interconnections to global operands and runtime groups, and the interconnections between the charts are retained. You get a 1:1 copy with a new name. • Supplementary documentation: In hierarchy folders you can import or create supplementary documentation (Text, Excel or Word documents). This gives you the opportunity of assigning documents to a subsystem or to process IC points. The associated dialog box is displayed for a selected hierarchy folder via: Insert > S7-Software > Supplementary documentation .

You can also see whether the name of the hierarchy folder is longer than that set under Options > Technological Hierarchy > Settings . Longer names can occur, for example, when copying from other projects or if the name layout is changed afterwards. A check report is issued after checking.
