Siemens PXC Controller Series Part-1
- 1. Siemens PXC Controller Series Part-1
- 2. The PXC Compact Series operates on the Automation Level Network (ALN) or the Field Level Network (FLN). When connected to the ALN, the PXC Compact uses a logical point firmware database to communicate directly with PXC Modulars, MBCs, RBCs, MECs, SCUs, and other nodes on the network. When connected to the MS/TP FLN, the PXC Compact operates as a third-party BACnet device. When the PXC-16 or PXC-24 is connected to the P1 FLN, it operates as a P1 device. 1.No license is required when using the PXC Compact as an FLN device. 2.PXC Compact on P1 displays as a TEC with application range 3000-3899. The PXC Compact is available with 16, 24, or 36 point terminations. Selected PXC-24 and PXC-16 models provide an extended temperature range for the control of rooftop devices. Optional hot-swappable HOA (Hand/Off/Auto) Modules for the PXC Compact Series enable output points to be manually placed into HAND, ON/OFF, or AUTO control. Compact Series Product Overview
- 3. The PXC Compact Series (Programmable Controller– Compact) is a high-performance Direct Digital Control (DDC) supervisory equipment controller, which is an integral part of the APOGEE® Automation System. The PXC Compact Series offers integrated I/O based on state-of-the-art TX-I/O™ Technology, which provides superior flexibility of point and signal types, and makes it an optimal solution for Air Handling Unit (AHU) control. The PXC Compact operates stand- alone or networked to perform complex control, monitoring, and energy management functions without relying on a higher-level processor. The PXC Compact Series communicates with other field panels or workstations on a peer-to-peer Automation Level Network (ALN), or on the Field Level Network (FLN), and supports the following communication options:(Ethernet/IP ALN,RS-485 P2) The PXC Compact is available with 16, 24, or 36 point terminations. Selected models in the Compact Series provide the following options: Support for FLN devices. An extended temperature range for the control of rooftop devices. Support for Island Bus, which uses TX-I/O modules to expand the number of point terminations for high-speed loop control. For PXC- 36 only. Compact Series Product Overview
- 4. Features DIN rail mounted device with removable terminal blocks simplifies installation and servicing. Proven program sequences to match equipment control applications. Built-in energy management applications and DDC programs for complete facility management. Comprehensive alarm management, historical data trend collection, operator control, and monitoring functions. Sophisticated Adaptive Control, a closed loop control algorithm that auto- adjusts to compensate for load/seasonal changes (License required with Firmware revision 2.8.18 and higher). Message control for terminals, printers, pagers, and workstations. Highly configurable I/O using Siemens state-of- the-art TX-I/O™ Technology. HMI RS-232 port, which provides laptop connectivity for local operation and engineering.
- 5. Features Extended battery backup of Real Time Clock. Persistent database backup and restore within the controller. Optional HOA (Hand/Off/Auto) module for swappable and configurable HOA capability. Optional extended temperature range for rooftop installation. Optional peer-to-peer communications over industry-standard 10Base-T/100Base-TX Ethernet networks. Optional support for FLN devices. Optional support for P1 Wireless FLN. Optional operation as a P1 FLN device with default applications. Optional support for Virtual AEM.
- 6. The Compact Series In addition to building and system management functions, the Compact Series includes several styles of controllers that flexibly meet application needs. PXC-16 The PXC-16 provides control of 16 points, including 8 software-configurable universal points. Point count includes: 3 Universal Input (UI), 5 Universal I/O (U), 2 Digital Input (DI), 3 Analog Output (AOV), and 3 Digital Output (DO). PXC-24 The PXC-24 provides control of 24 points, including 16 software-configurable universal points. Point count includes: 3 Universal Input (UI), 9 Universal I/O (U), 4 Super Universal I/O (X), 3 Analog Output (AOV), 5 Digital Output (DO). PXC-36 The PXC-36 provides control of 36 local points, including 24 software-configurable universal points. Point count includes: 18 Universal I/O (U), 6 Super Universal I/O (X), 4 Digital Input (DI), and 8 Digital Output (DO). The PXC-36 offers the flexibility of expanding the total point count through a self-forming Island Bus. With the addition of a TX-I/O Power Supply, up to four TX-I/O modules can be supported. For more information, see the TX-I/O Product Range Technical Specification Sheet (149-476).
- 7. Ethernet or RS-485 ALN • Support for APOGEE P2 ALN through TCP/IP or RS-485 networks. FLN Support ● The PXC-16 and PXC-24 “F” models with an FLN license support up to 32 P1 FLN devices when the ALN is connected to TCP/IP. ● The PXC-36 with an FLN license supports up to 96 P1 FLN devices when the ALN is connected to RS-485 or TCP/IP. ● A Wireless FLN may also be used to replace the traditional P1 FLN cabling with wireless communication links that form a wireless mesh network. Additional hardware is required to implement the Wireless FLN. P1 FLN Operation The PXC-16 and PXC-24 can be configured as a programmable P1 FLN device. In the P1 FLN mode, the PXC Compact functions as an equipment controller with customized programming and default applications. Available Options
- 8. Virtual AEM Support • The Virtual AEM license allows the PXC Compact to connect an RS-485 APOGEE Automation Level Network or individual field panels to a P2 Ethernet network without additional hardware. Extended Temperature Operation • PXC-24 "R" models support extended temperature operation, allowing for rooftop installations. Field Panel GO The PXC-36 supports Field Panel GO. The Field Panel GO license provides a Web-based user interface for your APOGEE® Building Automation System.
