Overview

Monitoring and configuration windows of the SITOP UPS software

DC UPS software

The DC UPS modules are optionally available with a USB port or

a serial port. All relevant messages about the status of the DC

UPS can be transferred to a PC (e.g. SIMATIC PC) via this inter-

face.

SITOP DC UPS software provides the user with a software tool

that is extremely easy to operate and can be used to further

process the signals sent from the DC-UPS module on the PC. In

monitoring mode, the status of the DC-UPS module is visualized

on the PC. Safe shutdown in the event of a power failure and

automatic PC restart are supported. It is also possible to freely

define responses to the different operating states of the DC UPS

module, permitting extremely flexible integration into a wide

variety of applications. The SITOP DC UPS software can be in-

stalled either as application or as service. When using it as ap-

plication an OPC server interface is available in addition to the

data exchange.

The software executes under the Windows Vista, Windows 2000

and Windows XP operating systems. It is available as freeware

on the SITOP Internet site for free downloading.
