High reliability and availability

The PDP800 supports full redundancy at all levels, including the PDP800 module, power supply, PROFIBUS DP link, and controller communication bus (HN800).

All redundancy options are independent of each other to ensure the highest level of availability and reliability.

Data Accessible to Control Applications

The functionally coded control application in the Symphony Plus controller has access to PROFIBUS device cycle data.

The data can be calculated, used as part of a control strategy, or displayed and alarmed at the S+ operator console.

An overview of the functions of the PDP800 is shown in Figure 2.

Managing Intelligent Field Devices

PROFIBUS devices are fully integrated into the Symphony Plus system, bringing benefits that go far beyond reduced footprint and cable costs.

In the S+ Engineering Workbench, field engineering tools support configuration, commissioning and maintenance of PROFIBUS devices using Device Type Manager (DTM) technology.

For field devices with a conventional device description file (GSD), standardised configurations are possible using the basic PROFIBUS DTM.

Individual device DTMs can be accessed from multiple data views (e.g. system or location overview, etc.) in Composer.

It includes automatic calculation of net values and loading of process items by using the device-specific channel configuration generated from the DTM.
