Siemens PXC….D – Automation stations, compact model CM1N9215en_25
Smart Infrastructure 2022-01-15
Functions
Compact, freely programmable automation stations for HVAC and building control
systems.
 Management functions (alarm management with alarm routing, schedulers, trend
functions, remote management, access protection with individually defined user
profiles and categories).
 For stand-alone applications or for use within a device or system network.
 BTL-tested BACnet communications on LonTalk, PTP or IP, compliant with BACnet
standard (Rev. 1.12 -for Desigo V6.0 and later) including B-BC profile.
 AMEV profiles AS-A and AS-B to recommendation "BACnet 2011 - Version 1.2
(for Desigo V6.0 and later)"
 Freely programmable, using the D-MAP programming language (close resemblance
to CEN standard 11312). All function blocks, available in libraries, can be graphically
connected.
 Engineering and commissioning using the Desigo Xworks Plus tool.
 Scalable range of touch panels, Web solutions and operator units
 Direct connection of field devices; the devices provide power supply for inputs and
outputs as well as for active sensors.
 Low voltage protection and start-up management to protect the devices against
fluctuating voltage.
