#Achema15 Integration of power supply into process control system.

Siemens is integrating its Sitop UPS1600 DC UPS with Ethernet/Profinet interface into the Simatic PCS 7 process control system. The energy storage units of the uninterruptible DC power supplies with 24 V DC output voltage and 10, 20 or 40 amperes current facilitate buffering of power failures for up to several hours.

Information about the operating state can then be transmitted, evaluated and visualized via software blocks. The software also automatically creates alarm messages. Users are then in a position to detect impending failures early on and initiate countermeasures, thus increasing plant availability.

New Sitop UPS1600 software blocks in the Simatic S7 controller permit direct data transfer (of operating and diagnostic data, for example) into the message system as well as of UPS faceplates of the process control system. The maintenance information can then be evaluated and visualized by the maintenance system of the Simatic PCS 7. In this way, users are clearly in the picture about the operating status of the power supply and connected energy storage units. During power outages or other disturbances, they can initiate counter measures or instigate replacement of the battery modules as measures to prevent potential downtimes. This is imperative particularly in the process industry since even short failures of individual components can result in high costs and in continuous processes can even make a time-consuming restart necessary.

In the coming months, Siemens will integrate more Sitop components, such as redundant 24 V network power supply units, or the Sitop PSU8600 power supply system, into the Simatic PCS 7 process control system. This provides optimum support during the engineering, operating and maintenance phases both for solution providers and plant operators using Sitop. The Sitop library for Simatic PCS 7 is available as a free download.
