Modular, 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)"....

Extension capabilities of the automation stations TXM1.. : The flexible range of TX-I/O modules for signaling, measuring, counting, switching, and positioning. The I/O modules with local manual control on the module housing permit the operator to control the equipment manually directly from the cabinet. 2) A high number of LonWorks devices reduces the performance of the PXC for connected TX-I/O or PTM-I/O data points respectively. Siemens Building Technologies

PXX-PBUS : The extension module allows connecting installed PTM-I/O modules to PXC50/100/200...D automation stations, making them the perfect solution to migrate legacy systems. Device combinations with the automation stations Adapter for Firmware download Siemens Building Technologies

Battery change 1) If one of the batteries has low charge the "BAT" LED lights up ant the automation station sends a system event. Remaining battery life after a "Low batt" event: • Battery for real time clock (Type CR2032): several days. • Battery for trend data and present parameters (Type AA Lithium): approx. 15 hrs. Alkaline: several days. • As long as there is an external power supply, the battery may be removed for unlimited time. • To prevent hardware damage by electrostatic discharge (ESD), a wrist strap with earth cable must be used during the battery change. • Note the special disposal...
