SIMATIC Route Control
Route Control engineering software
■ Overview
The Route Control (RC) configuration supplements the basic
SIMATIC PCS 7 plant configuration with blocks from the PCS 7
standard library. Existing plants are then also easy to upgrade
with SIMATIC Route Control. Technological elements of relevance
for control of the material transport (RC elements) are
adapted in the CFC Editor using uniform interface blocks from
the Route Control Library. The RC elements include:
• Control elements (actuators)
• Sensor elements (sensors)
• Parameter elements (setpoints)
• Connection elements (material information related to partial
route)

■ Function
Locations of partial or complete routes are configured in the-
SIMATIC Manager as "Equipment properties of plant units" and
transferred to the RC project together with the other RC-relevant
basic data of the SIMATIC PCS 7 project. The configuration requirements
caused by many repeated sequences can be minimized
by exporting locations in CSV format, duplicating and
modifying them using a spreadsheet program, and then importing
them again.
Locations (synonym: nodes) are parameters for requesting a
material transport (source, destination, intermediate locations/via)
and which mark the start and end of each partial route,
and thus also the source and destination of a material transport.
In addition to the basic tools (SIMATIC Manager, CFC, etc.) of
the SIMATIC PCS 7 engineering system, the following configuration
components of the SIMATIC Route Control Engineering program
package are available for configuration of the route control
applications:
Route Control library
The Route Control library contains blocks for RC and transport
route configuration and interface blocks for RC elements. It is
provided in the catalog of the CFC editor.
Route Control wizard
The Route Control wizard is the interface between the SIMATIC
PCS 7 basic configuration supplemented with RC interface
blocks and the actual RC configuration in the RC engineering
tool. The wizard, which can be called up from the SIMATIC Manager
menu, accepts the RC-specific configuration data of the
SIMATIC PCS 7 project into the Route Control engineering. In
doing so, it carries out plausibility checks, defines the AS-OS
and AS-AS communication connections (NetPro and CFC), and
configures the RC server signals.
Route Control Engineering tool
Following importing of the basic data of a SIMATIC PCS 7 project
relevant to the RC into an RC project, the RC-specific objects are
configured using the Route Control Engineering tool:
• Partial routes:
division of the transport paths into partial routes is used to increase
the flexibility and minimize the configuring overhead
by means of repeated application. Relevant partial route parameters:
"bidirectional" and "priority" (lowest total of partial
route priorities is decisive when searching for the overall
route).
• Interconnections:
Through inclusion in a partial route, the RC elements receive
additional properties depending on the type, and these can
be edited using configuration dialogs (e.g. in the basic setting:
"close valve").
• Function catalogs:
The partial routes can be assigned to function catalogs depending
on technological and product-specific aspects, e.g.
"cleaning" or "product transport". In the route search, function
catalogs permit restriction of the resulting quantity to the type
of material transport.
• Function steps/sequence functions:
Function catalogs contain as many as 32 configurable technological
sequence functions which define the sequence of material
transport by means of the RC elements connected in the
partial routes, e.g. base position of the control elements, open
transport valves, open origin valve, switch on pump).
