Siemens’ new Desigo controllers transform buildings into high-performing assets

Efficient engineering and commissioning
The new controllers were simultaneously released with the Desigo Engineering Framework, which consists of the HIT Portal, a web-based planning and selection tool; the engineering and commissioning tool ABT Site for PC users and the commissioning tool ‘ABT Go’ app for mobile use. The framework doesn’t require a license and can support the building throughout its entire lifecycle. With a wide number of pre-configured functions as well as program blocks and various example sites, the engineering tool ABT Site offers simplified programming to highly reduce engineering complexity. Thanks to the open by design approach, multiple protocols can be integrated and mixed easily. With this setup, projects can now be processed easier, faster and more reliably – on- site or remotely.

Remote and on-site access
Working remotely has never been more important than today. The new Desigo controllers PXC4 and PXC5 facilitate not only the engineering process, they also help the user reduce project time and cost. Unnecessary travel to physical sites can be avoided due to integrated cloud connectivity. Additionally, the controllers can be accessed with the Desigo Engineering Framework at any time and anywhere to perform remote engineering, operation and monitoring.
On-site, the user has wireless access to the controller and can process alarms on- site or remotely. The controllers have been designed with security in mind, offering certificate handling as well as signed firmware to prevent malware and viruses. Both devices, the PXC4 and the PXC5, have stringent system hardening tests and are prepared for BACnet Secure connect, the addendum to the BACnet protocol. What’s more, the communication with the embedded server is encrypted via https. Password protection and the disabling of the hotspot are two other features that improve security.
The new Desigo controllers are the first of a new range of building automation controllers that expand and strengthen the Desigo system, creating high-performing buildings with elevated levels of efficiency across the board.
