Conditioning and display of data on the PCS 7 TeleControl OS (single stations/servers) are carried out by SIMATIC PCS 7 TeleControl blocks present in a library. These blocks support operator prompting in conformance with SIMATIC PCS 7 using symbols and faceplates, and also the hierarchy of the SIMATIC PCS 7 alarms.

Special blocks in combination with SINAUT ST7 enable integral use of the Industry Library in S7?300 as well as S7?400 RTUs.

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

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.

When linking RTUs by means of the SINAUT ST7, DNP3, IEC 60870?5?101 or IEC 60870?5?104 telecontrol protocol, the raw data in the remote stations is provided with a time tag and transmitted to the PCS 7 TeleControl OS (server/single station) acting as control center. Adaptation, further processing and archiving are carried out there. This procedure is appropriate for the event-based principle of operation of the telecontrol protocol as well as the subsequent chronological processing of data which was buffered in the remote station.

The time and date of the remote stations connected per SINAUT ST7, DNP3, IEC 60870?5?101 or IEC 60870?5?104 can be synchronized by the PCS 7 TeleControl OS (time master). Switchover between daylight-saving time and standard time is also taken into account.

In order to comply with guidelines, statutory directives and standards it may be necessary to provide special proof, e.g. proof of conformity with the ATV M260 guideline for sewage treatment plants. For this we recommend the ACRON software package equipped with even more functionality for long-term archiving and logging. ACRON is an add-on product in the Catalog ST PCS 7 AO (Add-ons for SIMATIC PCS 7).
