Downloading
14.4 Downloading to a PC Station
Prerequisites
As of STEP 7 V5.1, Service Pack 2, you can completely load PC stations - such as
S7-300 or S7-400 stations.
• To download STEP 7 completely to the PC station, you must configure the PC
station as target system via Component Configurator (this Component
Configurator is part of the SIMATIC NET CD as of 7/2001). An index is here
assigned to the PC component. This procedure corresponds with the insertion
of modules into an S7-300/400 station.
Once you have entered your configuration of the PC station, you can use the
SIMATIC NCM PC wizards to store it as a project for subsequent reuse in STEP
7 (for example, you can copy it by drag-and-drop to your STEP 7 project and
then configure connections to other stations).
• The PC Station must be accessible online: either STEP 7 is installed on the PC
station or the PC station is accessible for the creating system (PG/PC with
STEP 7) via subnet and respective interfaces (CPs or integrated interfaces).
Downloading while Configuring Networks
You can carry out all load functions while you configure networks with STEP 7 (for
example Download > Selected and Partner Station, ... Subnet Stations etc.).
The procedure is the same as for loading S7-300/400 stations.
System files and a configuration file (*.XDB file) are still generated when a
SIMATIC PC configuration is compiled and stored. However, you do not need this
configuration file to 'convey' the communication configuration to the PC station.
Routing information for Slot PLCs and Software PLCs (WinLC) is automatically
downloaded to the PC station if it represents a network interface.
Previously, download to a PC station was only possible via the integrated
interfaces of Slot PLCs or via a CP on Index (slot) 9.
Downloading While Configuring Hardware
Note the following, especially when you download a hardware configuration:
Index (row) 125 in the configuration table of a PC station contains the fixed entry of
the 'Station Manager'. The Station Manager represents, on the project side (STEP
7), the entire configuration of the SIMATIC PC station.
On the target system side (PC station), a SIMATIC NCM runtime component
function interprets the downloaded configuration data (SDBs). This runtime
component is created with the Component Configurator (on the SIMATIC NET CD
as of approx. 7/2001). In this way, the PC station can compare the downloaded
configuration with the actual configuration and, in case of error, for example,
transmit messages relating to differences between the default and actual
configuration.
