Configuring Central Racks
2.3.3 Arranging the Central Rack
Requirement
Procedure
The station window must be open and you must have a plan of the hardware
configuration of the station.
1. Select a suitable central rack ("Rack") for your configuration from the
"Hardware Catalog" window; in SIMATIC 300 the Rail, in SIMATIC 400 the
Universal rack (UR1), for example.
2. Drag the rack to the station window.
The rack appears in the form of a small configuration table in the upper part of
the station window. In the lower part of the window, the detailed view of the
rack appears with additional information such as the order number, MPI
address, and I/O addresses.
Alternatively to steps 1 and 2, you can also double-click the rack in the
"Hardware Catalog" window.
2.3.4 Arranging Modules in a Rack
Requirements
Procedure
You have arranged a rack in a station window and the rack is not shown minimized
(the rack slots are visible).
If you want to have the visual advantage of having the available slots of a selected
module highlighted in color in STEP 7, your monitor display must set for more than
256 colors.
1. Select a module (for example, a CPU) from the "Hardware Catalog" window.
The slots available for this module are highlighted in color.
2. Drag & drop the module into the appropriate row of the rack (configuration
table). STEP 7 checks whether any slot rules are violated (an S7-300 CPU
must not, for example, be inserted in slot 2).
Symbol that appears when the slot rules are violated.
3. Repeat steps 1 and 2 until the rack has been fully equipped with the required
modules.
Alternatively, you can also select the appropriate row in the configuration table and
double-click on the required module in the "Hardware Catalog" window.
If no row in the rack is selected and you double-click a module in the "Hardware
Catalog" window, the module will then be placed in the first available slot.
