DP/AS-Interface Link 20E
Release 11/2002
C79000-G8976-C138–04
1.9.5 Upload Actual Configuration
Aims
You can upload the current actual configuration over the AS–i Link 20E to the open
STEP 7 project.
This allows you
S to read in a complex configuration and to use it as a basis for further
configuration in STEP 7;
S to check the current configuration.
Notice
The uploaded configuration is always the current actual configuration. The actual
configuration can differ from the configuration set with the buttons and stored on
the AS–i master, for example, when a slave was subsequently removed or added.
If you download the configuration from the STEP 7 project to the AS–i Link 20E,
the configuration detected during button configuration is overwritten.
Follow the steps below
Preparation: Create and download the basic configuration:
1. Create a basic configuration by inserting the AS–i Link 20E in a DP master
system of an S7–300 / S7–400 station.
2. Download this basic configuration to the S7 station with HW Config.
Uploading:
3. Then select the “Options AS–i Slaves” tab
4. Click the “Upload to PG” button.
An existing defined configuration is overwritten. Prior to accepting the
configuration, you must confirm a warning.
5. Then change to the “Slave Configuration” tab to view the current actual
configuration and, if necessary, edit it.
Tip:
To use this function simply for information despite an existing defined configuration
in STEP 7, you can upload the actual configuration, check it and then click the
“Cancel” button in the dialog.
