Compact Series Product Overview

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.

– No license is required when using the PXC Compact as an FLN device. – 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.

Support for FLN Devices

● Selected models in the PXC Compact Series can support P1 or MS/TP FLN

devices. Those which support FLN devices may require an additional license. Selected models can be purchased with the license already installed.

NOTE:

No license is required when the PXC Compact is being polled as an FLN device on the P1 or MS/TP FLN.

TX-I/O Island Bus Support

● The PXC-36 supports the TX-I/O Island Bus, which uses TX-I/O modules to

expand the number of point terminations.

– Selected PXC-36 models require a license to support the TX-I/O Island Bus. – For more information on connecting the PXC-36 to the Island Bus, see the TX-

I/O Island Bus Technical Reference Manual (140-0914).

Compatibility with the APOGEE Automation System

The PXC Compact Series in P2 Mode is fully compatible with and will communicate with all the APOGEE or pre-APOGEE products in your facility. However, PXC Compact Series in P1 Mode is not designed for use on the FLN of a pre-APOGEE field panel.

CAUTION

When working on a network with multiple firmware revisions, always connect to the

operator interface at the field panel with the newest firmware revision. Otherwise, you cannot view features in newer firmware revisions, or the field panel may coldstart.

BACnet Protocol Compatibility

APOGEE BACnet is compatible with the BACnet/IP protocol.

CAUTION

When sharing data values from APOGEE P2 (proprietary) field panels to BACnet

devices, the Cross-Trunk Service does not support requests originating from BACnet devices to access points (objects) that reside in APOGEE P2 field panels.

If you plan to share data values from APOGEE P2 field panels with BACnet devices (field panels), you must do one of the following:

● Install and enable the Insight BACnet Server Option.

● Use PPCL in the APOGEE P2 field panels to command values in the BACnet

devices through the Insight Cross-Trunk service.

APOGEE P2 and BACnet Product Features Order of Implementation

The APOGEE field panel firmware supports the BACnet protocol as follows:

● If both the BACnet and APOGEE protocols have a function, the BACnet function is

implemented.

● If APOGEE provides a function that the BACnet protocol does not support, the

APOGEE function is retained.

This approach to BACnet implementation retains the APOGEE feature set while providing compatibility with standard BACnet/IP protocol.

TCP/IP Protocol Compatibility

PXC Compact Series controllers with BACnet/IP or Ethernet TCP/IP (P2) ALN provide the following:

● 100% compatibility with the TCP/IP protocol suite.

● Support of Dynamic Host Configuration Protocol (DHCP) and Domain Name

Servers (DNS).

● Support and auto detection of 10Base-T and 100Base-TX Ethernet.

Required IP Addresses

APOGEE BACnet/IP or Ethernet TCP/IP (P2) ALN uses:

● One IP address per device (field panel or workstation).

● One additional shared IP address per ALN for the multicast group (when using

multicast optimization).

Device Registration

Devices register with the DHCP server and Domain Name Server, if either is present.

Address Assignment

IP addresses are dynamically assigned by the DHCP server.

If an address changes or is not recognized, the field panel firmware lets you release the dynamically assigned IP address and then reconnect the field panel to the DHCP server, accepting a new IP address assignment in the process.

If there is no DHCP server at the site, you must manually assign static IP addresses as part of the startup system configuration.

Physical Addressing

Each device on the BACnet/IP or Ethernet TCP/IP (P2) ALN has a hard-wired MAC address, which is printed on the product label.

Port Numbers

The default TCP/IP port number for APOGEE BACnet/IP or Ethernet TCP/IP (P2) ALN communications is

5033. You can change the TCP/IP port number if necessary.

NOTE:

All devices on the network must use the same TCP/IP port number.

The default TCP/IP port number for Virtual AEM communications is 3001. You must specify a UDP port number when using multicast optimization. The default

UDP port number is

Network Bandwidth

BACnet/IP or Ethernet TCP/IP (P2) ALN does not add significantly to your network overhead. Burst conditions for this product occur during:

● Database downloading after coldstart.

● Database uploading.

● Trend data uploading.

● Burst of alarms or COVs.

Data Exchange

BACnet/IP or Ethernet TCP/IP (P2) ALN sends and receives APOGEE data in TCP/IP packets.

BACnet/IP or Ethernet TCP/IP (P2) ALN synchronizes global data between all devices. Each device runs a global data replication engine that communicates with peer devices to:

● Exchange new and changed global data.

● Resolve conflicts when data does not match.

Device Naming Conventions

Field panel DNS node names are limited to 30 characters and cannot contain spaces.

Network Security

BACnet/IP or Ethernet TCP/IP (P2) ALN uses your intranet security within the firewall and a username/password combination to restrict access outside the firewall. You can use VLAN to improve internal security.

System Program

The PXC Compact contains a non-volatile system program called

firmware

, which can

be upgraded in the field. The firmware is stored in Flash ROM memory, which keeps it

Compact Series Product Overview

virtually immune to all forms of power fluctuations or failure, including battery failure. For more information on Flash ROM memory, see Memory [➙ 21].

General functionality of the firmware includes:

● Executing control programs.

● Communicating between other field panels and the workstation.

● Monitoring points.

● Managing point-related information.

● Keeping track of real time (both clock and calendar time).

● Executing self-test and error detection in the PXC Compact.

Minimum Firmware Revision Required

The APOGEE Field Panels Configuration and Sizing Guidelines (145-214) outlines the minimum firmware revision required for support of a specific feature with the PXC Compact Series.

License Manager

The licenses used to activate features are associated with a specific field panel through the ID_STRING. The ID_STRING uniquely identifies a piece of hardware; it is burned into the field panel’s EEPROM and read by software and firmware.

The ID_STRING is composed of the panel's part number, revision, year and week of manufacture, and serial number. Therefore, a license for one field panel will not work on another field panel. Information for the ID_STRING can be found:

● Printed on a label adhered to the outside of the field panel,

● Printed on a label adhered to the outside of the field panel shipping box, or

● Burned into the field panel’s non-volatile memory and read through Commissioning

Tool (CT), Insight software, or the field panel HMI.

For PXC-36 field panels that include FLN support, a default license named FLNNode36_254 displays in the field panel configuration.

CAUTION

Licensed FLN support only works if the correct license is loaded on the field panel.

An FLN license for PXC-16 and PXC-24 field panels supports 32 FLN devices.

For field panels that include island bus support, a default license named TXIOExp_8 displays in the field panel configuration.

NOTICE

PXC Compact Series models with Island Bus support allow four TX-I/O modules.

See the APOGEE Field Panels Configuration and Sizing Guidelines (145-214) for more information on applications and functionality that can be activated through License Manager.

See the License to enable SNMP Agent on Siemens Modular or Compact hardware with BACnet Firmware Revision 3.2.3

(LSM-SNMP) for information on adding licensed

applications or functionality.

Purpose of Licenses

The use of licenses and features allows added flexibility for customers. Because many features add functionality to a field panel’s firmware, a single part number can be ordered and installed. Additional functionality can be added at a later date without the need to replace the hardware or perform a firmware flash.

Example

A PXC-16 or PXC-24 field panel with an FLN Expansion Module is installed on the ALN to serve as a director for FLN devices; it only passes information about FLN devices to other ALN devices. The customer orders product number PXC36-E.A, which does not provide FLN support or TX-I/O island bus support.

Two years later, the customer decides to add physical points. By adding the TX-I/O island bus license, the PXC-16 or PXC-24 is converted to product number PXC16.2EF.A or PXC24.2-EF.A which provides FLN and TX-I/O island bus support. Without replacing the PXC-16 or PXC-24 hardware or firmware, the customer can now install TX-I/O modules and expand the number of physical points.

Custom Sensor Support

In both P2 Mode (ALN device) and P1 Mode (FLN device), the PXC Compact supports three custom sensor inputs for the AI points: Johnson Controls Nickel 1000, DIN Standard Nickel 1000, and Thermistor 10K Type 3. These sensors display as an option under the Sensor type HMI prompt when entering an AI point at the HMI.

Memory

The APOGEE firmware (program), its point database, PPCL program, trend data, and other information reside in the field panel memory. Memory consists of two areas: Flash Read-Only Memory (Flash ROM) and Random Access Memory (RAM).

Flash Read-Only Memory (Flash ROM)

Flash Read-Only Memory (Flash ROM) is the non-volatile, permanent memory of the PXC Compact, which stores the operating system, the APOGEE firmware, and the language files. A limited amount of secondary storage is provided in Electrically Erasable Programmable Read-Only Memory (EEPROM) for the field panel address or name, communication speeds, and other set-up parameters. In the event of a power surge, a power loss, or failure of the battery backup, the Flash ROM and EEPROM contents stay intact.

PXC Compact Flash ROM size cannot be upgraded in the field.

Compressed ROM

The PXC Compact has a large amount of high performance RAM. To allow for future features and to provide high system performance, the APOGEE firmware is stored in ROM in a compressed state; it is de-compressed into RAM on system power-up. As a result, the entire onboard RAM is not available for the point database, the PPCL program, and trend data.

Auto-Restore and Database Backup to Flash

APOGEE Firmware Revision 2.8.4/3.1 and later supports Auto-Restore and Database Backup to Flash.

● Database Backup to Flash allows the user to manually save a copy of the

database in flash memory of the controller.

● The field panel may be configured to automatically restore the database from flash

memory after a coldstart.

– When auto-restore is enabled, a coldstart does not result in the same downtime

as with earlier revisions of APOGEE Firmware. Because there is no waiting on a full download from the backup system, the database is restored from flash so quickly that there is little to no downtime. However, the accumulated trend data is deleted from memory.

– Database restoration from flash is disabled by default. – When FLN Mode is selected for the PXC Compact or UEC, database

restoration from flash is automatically enabled.

– When P1 Mode is selected for the PXC Compact, database restoration from

flash is automatically enabled and 128K of memory is reserved for ISB files.

● The field panel may be configured to automatically restore the database from flash

memory after a coldstart.

– When auto-restore is enabled, a coldstart does not result in the same downtime

as with earlier revisions of APOGEE firmware. Because there is no waiting on a full download from the backup system, the database is restored from flash so quickly that there is little to no downtime. However, the accumulated trend data is deleted from memory.

– Database restoration from flash is disabled by default.

For procedures on using Auto-Restore and Database Backup to Flash, see the APOGEE P2 ALN Field Panel User's Manual (125-3019) or the APOGEE BACnet ALN Field Panel User's Manual (125-3020).

Auto Save

This feature allows the database to be backed up automatically whenever database is changed, instead of being an operator selected function. It does not provide any safeguard and or protection against power loss while the process is underway. However, this feature sends messages to HMI that the auto save operation is in progress or finished.

The feature may be turned on or off using a prompt similar to the existing Autorestore prompt. See the APOGEE BACnet ALN Field Panel User's Manual (125-3020) for more information.

File System Operations

File System Operations provide many features and works on three drives of a field panel.

The following is a list of supported features:

● List Drives — list the drives on the field panel where A: is the RAM drive, B: is the

USB drive if attached, and

IFD: is the internal Flash Drive.

● Set_drive — identifies the drive that you want to perform other functions on.

● listDirectory — lists the files and folders contained on the selected drive.

● Change_dir — changes the current directory to allow you to view the contents of

subfolders on the drive.

● File_ops — opens up the file control menu which allows you to copy, rename,

delete and move files in the panel. These functions work on the drive that was selected by the Set_drive function.

● File_ops/Copy_file — allows you to copy files within a drive or to another drive.

● File_ops/Rename_file — allows you to rename a file.

● File_ops/Move_file — allows you to move a file within a drive or to another drive.

● File_ops/Delete_file — allows you to delete a file.

USB Media Support

● Support for USB mass storage devices (Memory sticks or USB hard drives).

● Backup of database, storage for graphics, Web Server upgrades

Random Access Memory (RAM)

Synchronous Dynamic Random Access Memory (SDRAM) is the working memory of the PXC Compact. When the PXC Compact has booted and is operating normally, the APOGEE firmware, the PPCL control program, the point database, and trend data have been transferred from Flash ROM. Information stored in RAM, such as the point database or PPCL, may be viewed, modified, deleted, activated, or deactivated from an operator terminal by any high-level authorized user. In the event of a power loss, the contents of RAM are kept intact by a backup battery.

PXC Compact RAM size cannot be upgraded in the field. The program length, number of database points, and number of trend entries is limited

only by available memory.

Compact Series Backup Batteries

The PXC Compact Series contains one non-rechargeable AA (LR6) battery and one non-rechargeable coin cell (BR2032) battery that serve as a power backup in the event

of a power failure. The batteries only discharge during a power loss. They do not recharge.

CAUTION

Only use a 3.6 Volt lithium battery in PXC Compact models with extended

temperature range operation. Only use a 1.5 Volt alkaline battery in standard PXC Compact models.

• The 3.6 Volt lithium battery is designed to operate at both high and low temperature extremes, and it provides a long service life in an extended temperature environment.

• The 1.5 Volt alkaline battery is not guaranteed to provide backup protection in models with extended temperature range operation, even if the controller is operating in a room-temperature environment.

• If a 3.6 Volt lithium battery is used in standard PXC Compact models, the battery quickly discharges and provides much less backup protection than a 1.5 Volt alkaline battery.

AA Battery

CAUTION

Batteries

Failure to change DEAD alkaline battery will eventually result in battery leakage, causing permanent damage and loss of building control.

Failure to change a DEAD lithium battery will result in loss of trend and database if not backed up, causing loss of data or building control.

Establish a preventative maintenance schedule based on expected battery usage and life cycle.

● The AA battery maintains databases and volatile data, such as Trend, in RAM

when power to the controller is off.

● If reserve power in the AA battery is low, the battery status is reported as LOW or

DEAD and the red LOW BATT LED on the field panel is lit. When this occurs, replace the battery; do not wait until it goes dead.

● Using PPCL and the $BATT point, the PXC Compact can be programmed to signal

an alarm printer and an operator terminal with a battery replacement message.

For more information, see the APOGEE Powers Process Control Language (PPCL) User's Manual (125-1896).

Using Auto Restore and Database Backup to Flash

● RAM is cleared if the AA battery is dead, disabled, or missing when power to the

field panel is off. In this case, if Auto Restore and Database Backup to Flash have been enabled, the database reloads in RAM when power returns; however, Trend data is lost.

● If a power failure lasts longer than the protection offered by the battery, and Auto

Restore and Database Backup to Flash are not enabled, the information stored in RAM must be either reloaded from an Insight workstation, Datamate Base or Datamate Advanced, or entered again by an operator.

● The coin cell battery maintains the current time-date in the Real Time Clock (RTC)

when power to the field panel is off.

● There is no physical status on the field panel for a dead coin cell battery.

● If the coin cell battery is dead or missing when power is off, then RTC time-date is

reset as follows:

– If the field panel resides on an ALN with an Insight workstation, the Insight

workstation sets the time-date when the field panel returns to the network.

– If the field panel resides on an ALN without an Insight workstation, the time-

date is synchronized with the network time during the next automatic daily time update.

● When the PXC Compact is operating in P1 mode, if the coin cell battery is dead or

missing when power is off, RTC time-date is reset to the factory default. RTC timedate and must be set manually or by PPCL to ensure time-date based applications operate as expected.

For more information on time synchronization, see the APOGEE P2 ALN Field Panel User's Manual (125-3019) or the APOGEE BACnet ALN Field Panel User's Manual (125-3020) (125-3019 or 125-3020).

Monitoring the State of the Coin Cell Battery

● Resident AI point BATT2 monitors the state of the RTC oscillator when power is

applied to the field panel either during a coldstart or a warmstart.

– If the oscillator is stopped, BATT2 is set to value 0. – If the RTC oscillator is valid, BATT2 is set to value 100. – Status is reported as DEAD for a value of 0. – Status is reported as OK for a value of 100.

NOTE:

The value of

BATT2

is also set to

100

by a coldstart command. Since the controller is powered and the RTC oscillator does not stop, the value of BATT2 is valid and a time-date reset will not occur.
