New software modules for process control system

Integration of 24 Volt supply concepts

Nuremberg, Germany. Siemens is expanding its Sitop library for the Simatic PCS 7 process control system to include a range of new functions. These allow users to simply integrate 24 volt supply concepts such as a redundant power supply, selective monitoring of 24 volt load circuits or buffering in case of a power failure into the process control system using software modules. Users are automatically provided with information on operating statuses, as well as maintenance or error messages. In addition, selected device data can also be read out and displayed. The Sitop library for Simatic PCS 7 is available as a free download. The Sitop library contains modules and faceplates for direct integration into the Simatic PCS 7 process control system for power supply concepts. Software modules in the Simatic S7 supply the faceplate in the user interface of the process control system with operating and diagnostic data, generate messages and ensure connection to the PCS 7 maintenance system. As a result, users benefit from constant transparency of the 24 volt supply in the control system. PCS 7 users are automatically provided with information on operating statuses such as buffering operation, the need for maintenance steps (such as a battery change) as well as faults – for instance in case of a short circuit or an overload in 24 volt circuits. This allows critical plant statuses to be quickly detected, preventing failures with their associated costs and bringing about a sustainable increase in plant availability.
