PCS 7 TeleControl engineering station

Engineering station of the SIMATIC PCS 7 process control system SIMATIC PCS 7 TeleControl block library

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.

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.

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).
