SIMATIC PCS 7 process control system

SIMATIC PCS 7 process display: route network overview
Route Control engineering
The configuration of Route Control builds on the basic configuration
of the SIMATIC PCS 7 process control system using
blocks from the PCS 7 standard library. Even existing SIMATIC
PCS 7 plants are therefore easy to expand with SIMATIC Route
Control.
Technological elements of relevance to control of 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)
■ Sensors elements (sensors)
■ Parameter elements (setpoints)
■ Connection elements (material information related to partial
routes)
Route Control library
The Route Control library contains blocks for RC configuration,
blocks for creating transport routes, and interface blocks for
RC elements. It is made available in the catalog of the
CFC editor.
Route Control wizard
The Route Control wizard constitutes the interface between
the RC configuration and the SIMATIC PCS 7 basic configuration.
The wizard, which can be called up from the SIMATIC
Manager menu, receives the RC-specific configuration data of
the SIMATIC PCS 7 project for importing into the Route Control
engineering. In doing so it carries out a plausibility check, defines
the AS-RC server and AS-AS communication connections,
and creates the RC server signals.
Route Control Engineering tool
Once the RC-relevant basic data of a PCS 7 project have been
adopted in an RC project, the next step is to configure the
RC-specific objects with the Route Control Engineering tool:
■ Partial routes: through division of the transport paths into
partial routes, it is possible to increase the flexibility and
reduce the configuring overhead through repeated applications.
Relevant partial route parameters: "bidirectional"
and "priority" (lowest total of partial route priorities is decisive
when searching for the overall route)
■ Locations: marking of beginning and end of each partial
route and thus also of the origin and destination of a material
transport through plant points; these are parameters
for the requirements of a material transport (origin, destination,
intermediate points/via).
■ Interconnections: "interconnection" of the RC elements
through installation in a partial route; the elements acquire
additional properties depending on their type
(e.g. "close valve" in base position). These properties
can be edited in configuration windows.
■ Function catalogs: partial routes can be assigned to certain
function catalogs, e.g. "Cleaning" or "Product transport",
according to technological and product-specific aspects.
When searching for routes, function catalogs allow
you to limit the results to the type of material transport.
■ Function steps/sequence functions: each function catalog
includes as many as 32 configurable technological sequence
functions, e.g. base position of the control elements,
open transport valves, open origin valve, switch on
pump. Together with the RC elements interconnected in
the partial routes, the sequence functions determine the
sequence of material transport.
Special configuration functions make it easier to perform repetitive
routine work and extend the range of options for controlling
material transport, e.g.:
■ Exporting configuration data in the form of CSV files to
MS Excel, copying and editing the data there, and then importing
the files back into Route Control
■ Controlling the joint use of partial routes by configurable
function IDs
■ Checking material compatibilities and interlocking partial
routes in case of incompatible material sequences based
on the material ID saved in the connection element of the
partial route
■ Connecting dynamic (external) setpoints arriving from
the process (e.g. weighed quantity) to the route block in
runtime
