PCS 7 TeleControl blocks for system-conformant operator control and monitoring

The RTUs are integrated into the PCS 7 TeleControl Operator System by means of the PCS 7 TeleControl blocks such that there is no difference for the operator with regard to operat- ing philosophy and alarm behavior for the central or remote automation functions.

The blocks required for data conditioning and display are saved in a library. These blocks support SIMATIC PCS 7 compli- ant operator control by means of symbols and faceplates, as well as the hierarchy of SIMATIC PCS 7 fault messages.

In addition to blocks for processing of process data, the library also contains blocks for diagnostics and for control of communication. If necessary, the supplied basic library can be extended by new script-based block types specific to the project by using the DBA Type Editor.

Long-term archiving and logging

The PCS 7 TeleControl Operator System includes a high-perfor- mance cyclic archive based on Microsoft SQL Server for time- limited saving of process values and messages/events. Data from this cyclic archive can be exported time-controlled or event-controlled to a long-term archive (StoragePlus/central archive server).

The logging system of the PCS 7 TeleControl Operator System supports the display and evaluation of data recorded during operation by means of various predefined types of protocol which can also be matched individually:

•Message sequence report

•Message and archive log

•Measured value log

•Operator input log

•System message log

•User log

The logs saved in EMF format can be previewed on the screen, and can be printed manually or time- or event-controlled.

In order to comply with statutory directives and standards it may be necessary to provide special proof, e.g. proof of con- formity with the ATV M260 standard for sewage treatment plants. The SIMATIC PCS 7 add-on product ACRON equipped with additional functionalities for long-term archiving and logging provides excellent support for this purpose.
