Siemens: New Basic Unit for Easy Diagnostics and Setup of Power Supply Systems

April 27, 2020

Siemens is expanding its modular Sitop PSU8600 power supply system to include a new single-phase 480-watt basic unit. The new product features four integrated monitored outputs with a total of 24 volts DC at five amperes per output. Each output is flexible and can be set during operation in a range between 4 and 28 volts either manually or remotely via software. This eliminates the need for additional power supply units to supply five or twelve volt loads.

The CNX8600 expansion module can be used to monitor up to 36 total outputs. Thanks to its integration into the TIA (Totally Integrated Automation) Portal engineering framework, fast implementation in to the automation is supported. In addition, the Sitop Manager provides easy parameterization and diagnostics. Comprehensive diagnostic and maintenance information are also available via the two integrated Ethernet/Profinet interfaces and via OPC UA, and can be evaluated directly in the automation systems. This means that errors can be located quickly and reduces downtime.

The BUF8600 buffer module or the UPS8600 interruptible power supply module with the BAT8600 battery modules covers mains failures and the comprehensive monitoring and diagnostics functions reduce errors caused, for example, through the overheating or overload of one of the outputs. With the integrated web server and OPC UA server, remote diagnostics and third-party communication are well supported.

Integration into the TIA Portal or Step7 for network integration and device parameterization ensures that engineering is particularly simple. Step7 application programs feature for example function blocks for Simatic S7-300/-400/-1200/-1500. Simatic WinCC Faceplates can be used for integration into the Simatic PCS 7 process control system via the Sitop library. The user also benefits from reliable support for energy management thanks to the individual acquisition of current and voltage for each output and the targeted activation and deactivation of outputs via Profienergy.
