SIMATIC Route Control is fully integrated in SIMATIC PCS 7 and, 

thanks to the modular architecture and 3-step scalability (up to 

30 / up to 100 / up to 300 simultaneous material transports), can 

be flexibly adapted to different sizes of plant.
SIMATIC Route Control provides graded user privileges for en-

gineering, operating and maintenance personnel who are inte-

grated into the user administration with SIMATIC logon. SIMATIC 

Logon is an integral component of SIMATIC PCS 7.

The Route Control Engineering Tool, the Route Control Library 

and the Route Control Assistant are integrated together with the 

other engineering tools of the SIMATIC PCS 7 process control 

system in the central engineering system.
In SIMATIC PCS 7, blocks from the SIMATIC PCS 7 standard li-

brary are inserted into CFC plans and connected to plant control 

blocks in accordance with the technological requirements in or-

der to control and monitor the elements of a plant. These individ-

ual connections are omitted with SIMATIC Route Control (RC). 

You adapt the standard blocks of the technological elements rel-

evant to RC (RC elements) using standardized interface blocks 

from the Route Control library, and allow RC to control and mon-

itor the elements during operation. This is of course also possi-

ble with existing plantswithout an increased overhead.
The blocks of the Route Control library support redundancy at 

the controller level. They can be used with standard automation 

systems or also with fault-tolerant systems or mixed configura-

tions. The changes in the engineering system can be recorded 

(Change log), both in the SIMATIC PCS 7 project and in the RC 

project.
The Route Control Assistant functions as the interface between 

the PCS 7 basic configuration expanded by RC components 

and the RC engineering tool. It analyzes the hardware and soft-

ware configuration of the SIMATIC PCS 7 (multi-)project, and 

generates a database which serves as the basis for further, 

RC-specific configuration with the RC engineering tool.
During the RC-specific configuration, the elements imported 

from the SIMATIC PCS 7 project by the Route Control Assistant 

must be inserted into a sub-route structure. These sub-routes di-

vide the plant. The complete routes will be subsequently "joined 

together" from them during the automatic route searching. The 

response of the sub-routes in a particular function are already 

defined when inserting the elements into them. Functions repre-

sent the technological requirements when operating the plant 

(e.g. "Open source", "Pumps" etc.). 
As a rule: the more finely divided the sub-route structure, the 

more flexible the subsequent automatic route searching. With 

purely static routes, a sub-route can already be a complete 

route.

After the transport network has been configured and the variants 

of the material transports tested, the Route Control configuration 

data are transferred to the Route Control Server where they can 

be activated via the Route Control Center at a suitable time from 

the process engineering viewpoint. From then onwards, the new 

data are taken into consideration when searching for the route. 
If a material transport is pending during operation, a route (ma-

terial transport) is requested by the controller (e.g. using an 

adapted RC SFC type) or by the operator on the Route Control 

Center. In addition to definition of the source and target as well 

as up to 10 optional locations (intermediate points), this also in-

cludes the creation of a start signal on the route control block 

RC_IF_ROUTE in the automation system (AS). The AS "informs" 

the RC Server which then starts searching for the route and – if 

possible – combines the statically defined sub-routes into a 

complete transport route. From this point onward, the Route 

Control takes over control and monitoring of all RC elements in-

volved in the transport route. If faults occur, detailed diagnostics 

information is provided concerning the cause, e.g. why the 

search for a suitable transport route was unsuccessful. The plant 

control program only switches the individual technological func-

tions, everything else is handled by the Route Control.
The Route Control Server (RC Server) supplies the Route Control 

Clients (Route Control Center) with the necessary data and 

transfers their operations to the automation systems. 
For maintenance purposes, an automation system can be spe-

cifically set to "in maintenance" (out of service). The material 

transports being carried out by this automation system are still 

continued until finished. However, new material transports are no 

longer permitted.

In the process displays of the SIMATIC PCS 7 operator systems, 

each route block is represented by an RC block symbol and an 

RC faceplate. Through a route block’s RC block symbol it is pos-

sible to select its RC faceplate, and through a route block’s RC 

faceplate it is possible to select the Route Control Center. 

The selection of locations (synonym: nodes) is made simpler in 

the process display by means of drop-down lists.
