PCS 7 TeleControl engineering station
Engineering station of the SIMATIC PCS 7 process control system
To enable engineering of the PCS 7 TeleControl operator sta-
tion (single station/server), the functions of the engineering
station of the SIMATIC PCS 7 process control system are ex-
panded by DBA technology (Data Base Automation) and the
SIMATIC PCS 7 TeleControl block library.

Data Base Automation (DBA)
Engineering can be automated efficiently and in conformance
with SIMATIC PCS 7 using the DBA technology. DBA supports
plant expansion during ongoing operation, and facilitates
project-specific adaptation of the system as well as importing
of existing configurations in the course of migration.

The DBA executed in the engineering station automatically
generates the OS runtime database with the display hierarchy,
required variables, alarms, alarm messages and alarm priori-
ties, as well as the specific faceplates and block symbols.

required variables, alarms, alarm messages and alarm priori-
ties, as well as the specific faceplates and block symbols.
The display hierarchy is the basis for navigation between the
process displays, for alarm management, and for implementa-
tion of safety measures. DBA positions the type-specific block
symbols, e.g. measured value, counter value, motor or gate
valve, in the process images. These symbols are linked to the
corresponding function blocks and faceplates through the da-
tabase. Manual configuration is mainly limited to the design
and positioning of the static graphic elements, e.g. pipes or
tanks.

SIMATIC PCS 7 TeleControl block library
In addition to the SIMATIC PCS 7 TeleControl basic library,
new user blocks can also be defined using the DBA type editor.
During database generation, the user blocks are treated like
the blocks from the basic library.

Using the DBA type editor it is possible to assign the frequently
unstructured variables of an RTU once to a block type and to
display the variable structured on the operator station via the
block's faceplate.

SIMATIC PCS 7 TeleControl blocks
The PCS 7 TeleControl OS symbols, faceplates and diagnostics
displays created in conformance with SIMATIC PCS 7 take into
account the specific features of telecontrol applications. This
is demonstrated, for example, by the example of the counter
block which offers versatile conditioning options for informa-
tion on transported or processed quantities. At least one
OS faceplate and one OS symbol are available for each type
of block.

In addition to arrangement of information in a variable struc-
ture, the user blocks generated with the DBA type editor can
also calculate derived values using Visual Basic scripts in the
server. This results in numerous possibilities for extending the
functionality and for adapting the system to individual cus-
tomer requirements.

Type-specific OS faceplates and OS symbols for the user blocks
can be created using the standard tools for SIMATIC PCS 7
OS engineering (Graphics Designer and Faceplate Designer).
