Assortment / System Description

7 A family of programmable automation
stations
PXC4 PXC5 PXC7
The Desigo PXC range offers flexibility and ease of use in controlling and
monitoring of building automation and control systems.
The modern system approach includes cloud connection to all PXC controllers as
well as user-friendly operation via Desigo Control Point.
Comprehensive system functions such as alarm management, time scheduling,
and trend data storage cover all the requirements associated with building
operations.
Decentralized automation stations operate autonomously via networked BACnet
communication, guaranteeing a high level of operational reliability. The automation
stations also support BACnet Secure Connect (BACnet/SC) to protect
communication between devices.
Integration of third-party devices via Modbus rounds out the list of feature for
optimized controllers.
The ABT Site tool provides efficient engineering and commissioning via WLAN,
Ethernet, or the cloud.
Alarm management
One of the most important functions of any building automation and control system
is automatic alarm notification plant alarms. Alarm management (generation,
display, and handling) must be simple, efficient, and consistent at all system levels.
Desigo takes advantage of BACnet alarm functions and supports the following
three types of alarms with up to 256 alarm priority levels:
● Basic alarms (no user interaction required)
● Simple alarms (acknowledgment required)
● Extended alarms (acknowledgement and alarm reset required)
Alarm messages
An alarm is automatically recorded, registered, and forwarded to a Desigo Control
Point or to a Desigo management station. Meaningful alarm messages are also
sent to remote devices.
Alarm lists provide an easy-to-read view of all pending and time-stamped alarms
for straightforward processing.
Pop-up windows and optical/acoustic signals notify the operators.
