USER GUIDE EXCEL WEB

SYSTEM OVERVIEW

General

	The Excel Web® is a BACnet/IP-based, freely programmable building automation
	controller.
	Excel Web® incorporates the two major open standards in building automation:
	BACnet® and LONWORKS®.
	As a native BACnet® building controller, Excel Web® integrates into any 3rd-party
	BACnet® system and can integrate 3rd party BACnet devices and controllers.
	Furthermore, Excel Web® is a full LONWORKS® controller. This gives the benefit of
	enabling you to use of Honeywell’s complete LONWORKS® product portfolio and 3rd-
	party LON products.
	The Excel Web® can host a huge variety of building management applications, be it
	traditional heating, ventilation, and air conditioning (HVAC) applications, energy
	management functions, including optimum start/stop, night purge, and maximum
	load demand, supervisory functions for lighting, sunblind, heat and energy metering
	and many other applications.
	By virtue of its "peer-to-peer" concept, Excel Web® is not dependent upon the
	availability of super ordinate centrals or application network controllers.
	Excel Web® seamlessly integrates into Honeywell’s Enterprise Buildings
	Integrator™ (EBI) and SymmetrE® front-ends.
	Versions and Firmware
Excel Web Versions	XL1000B50 / XL1000C50
	52 physical datapoints and 50 Schedule Objects, 128 trend objects

	For more details such as RAM size, please refer to Product Data EN0443-GE51.
Excel Web Firmware	Linux operating system
	XLWebExe-H-MM-LL.xwa, including firmware itself, BACnet driver and HTML pages
	(H-MM-LL are version numbers).
Updating Firmware	If, at some later point in time, i.e. after the release of a new version of the firmware,
	the user wishes to download the new firmware into the Excel Web, this can be done
	either via USB or Ethernet, using the CARE.
	Browser Access / Operater Interface
Operator Interface	The Excel Web® is operated via a standard web browser (Excel Web HTML
	Interface). By default, an integrated web server provides all operation pages for a
	full browser-based operation. Through the consequent use of software standards,
	any PC platform can be used as an operator interface (client). In addition to laptops
	and desktop PCs, panel PCs can also be used for direct flush mounting into panel

doors. Other than the operating system and Internet Explorer® or Netscape®, no software needs to be installed on the client PCs.

Alternatively – or in addition – Excel Web can be operated with the Excel Touch operator interface, which is a 5.7” touch-screen device (order number “XI882” For more details please refer to the Excel Touch product data sheet, form no. EN0B0615-GE51) or/and to the Excel Touch User Guide, form no. EN2B0615-GE51).

Access Modes to

Excel Web Controller Any Excel Web controller on the network can be accessed via the browser-based Excel Web HTML Interface, both locally and remotely. The Excel Web HTML Interface can reside on any PC platform client such as:

•Desktop PC

•Notebook, Laptop

•Touch panel PC

The controller can be accessed in one of the following ways:

• LAN (remote access)

	LAN
Excel Web Controller A	Excel Touch
Excel Web Controller B	BACnet Client

Desktop PC, Notebook

Fig. 1. Access to Excel Web controller via LAN

Permanent IP address, allocated by I.T. department

The Excel Web controller can be accessed remotely via LAN by allocating a valid and permanent IP address to the controller, which is reachable within the LAN.

Procedure:

See Establish Remote LAN Connection section in CARE User Guide

EN2B0182GE51 / 74-5587.

Alias IP address, factory default

For access via Ethernet, the Excel Web has a permanent factory default IP address 192.168.253.20 and Network Mask 255.255.255.0. Your PC's IP address must match the Excel Web controller's default IP address. We recommend using 192.168.253.21 and Network Mask 255.255.255.0.

When using this default address, you must ensure that you have only one powered-up Excel Web controller on your Ethernet; otherwise, communication will fail because all Excel Web controllers have the same permanent default IP address. Alternatively, you can use an Ethernet cross-over cable between your PC and the Excel Web controller rather than having your PC and the Excel Web controller both connected to a LAN.

Standard Ethernet Interface of your PC

Change the (factory-set) configuration of the integrated Ethernet card so as to match the Excel Web IP address and IP subnet.

NOTE:

In order to (subsequently) operate on your standard Ethernet network (again), you will have to change the configuration back to the previous settings.

Dedicated Ethernet Interface of your PC

If the laptop or PC with which you wish to access the Excel Web via Ethernet/IP is not already equipped with an integrated Ethernet Card, or if you want to leave

	BACnet Client
	Notebook, Touch panel PC, Desktop PC

Fig. 2. Access to Excel Web controller via crossover cable

To locally connect to the Excel Web controller via Ethernet, a crossover cable can be used. Hence it has temporarily no connection to any other network and the Excel Web controller is not reachable in the network.

The crossover cable connection type has the highest transfer rate (100 Mbit/s), but when applied, the IP address settings of the client need to be changed.

Procedure:

See Establish Local Ethernet Connection via Crossover Cable section in CARE

User Guide EN2B0182GE51 / 74-5587.

• USB (local access)

	LAN

Fig. 3. Access to Excel Web controller via USB

To locally connect to the Excel Web controller via USB interface, a D-Link DUB-

E100 USB 2.0 Fast Ethernet adapter can be used.

The USB connection type is recommended for the initial setup of an Excel Web controller due to a reasonable transfer rate (2 Mbit/s) and because no IP address changes are necessary after installation. In addition, the LAN connection can be used in parallel and uninterruptedly.

Permanent IP address, factory default

For access via USB, the Excel Web has a permanent factory default IP address 192.168.252.20 and Network Mask 255.255.255.0. Your PC's IP address of the Belkin USB network adapter must match the Excel Web controller's default IP address subnet: We recommend using 192.168.252.21.

Procedure:

See Establish Local Connection via USB Cable section in CARE User Guide

EN2B0182GE51 / 74-5587.

IP Address Allocation

To establish any of the described connections, IP addresses must be allocated to the relevant network components such as BACnet client, Excel Web controller(s) and USB network adapter.

•CARE access to Excel Web controller via modem

You can work with CARE on an Excel Web controller via modem by connecting remotely to the modem attached to the Excel Web controller. When the connection is established, CARE can connect to the Excel Web controller via IP address. LON-Commissioning can then be done by using a NIC IP (Loytec) additionally.

Communication Settings Communication settings in the Excel Web HTML Interface comprise:

•Interface settings such as serial baudrates, IP address, neuron chip ID, MAC address, automatic logout time of web server

•Modem settings

•Remote central (front-end) settings

Bus-Wide Operation Any user can operate all Excel Web controllers residing on a BACnet network.

Network

Based on its design as an IP device (see also "Communication Protocols"), the Excel Web controller "speaks" BACnet over IP (Internet Protocol) and hence, can be integrated smoothly and without the need for additional devices into any network infrastructure having regard to the corresponding network security mechanism.

Fig. 6. Networking model of Excel Web controller

Network Load	The network load for one Excel Web controller in combination with one EBI central
	is about 1 % network load in a 10 Mbit network.
	These figures are based on the following assumptions:
	• 20 BACnet properties per display
	• BACnet properties are updated by 5 EBI displays simultaneously
	• Each property is updated every 5 s. One update message for a simple property
	needs 100 bytes, for a complex property 200 bytes.
	Calculation: 5 displays * 20 properties/display * 150 bytes/property *
	1 update/5 s = 30000 bits per second.
	If alarms should be received and properties should be in trend, everything should
	not consume more than 100 Kbits/s, which is 0,1 % in a 100 Mbit network.
Communication Protocols	BACnet/IP - ISO 16484-5 – ENV 13321-1
	Communication with other Excel Web® controllers, with 3rd-party BACnet® devices,
	with Honeywell Enterprise Buildings Integrator™ and SymmetrE® front-ends, and
	with 3rd-party BACnet® front-ends is based on the international BACnet® Protocol.
	More details on the BACnet® Interoperability can be obtained from the Excel Web®
	Protocol Implementation Conformance Statement (PICS).
	LonTalk®
	Communication with physical I/O modules, with room and zone controllers, and with
	Excel 50/500 controllers is based on LonTalk®.
	A Free Topology Transceiver (FTT-10A or FT-X1) allows a communication speed of
	78 KBaud.
	In typical cases, field devices are controlled via Honeywell Distributed I/O
	(XFL52xB) or Smart I/O (XFCxxx) modules. Maximum cable lengths are 320 m to
	2,200 m.
	HTTP
	Excel Web® can be operated using a standard Internet Explorer (5.5 or higher) or
	Netscape (6.2.1 or higher). The required minimum screen resolution is 800 x 600
	pixels. For more details, please refer to the "Operating the Excel Web HTML
	Interface" section.
	FTP
	The firmware and application are downloaded via the standard FTP (File Transfer
	Protocol).
	Telnet
	Telnet access to the Excel Web controller is possible for the purpose of service and
	diagnostic of the Linux operating system and the Excel Web firmware. In case this is
	needed, please contact your Honeywell representative.

SMTP

Simple Mail Transfer Protocol is used for the embedded Email alarming functionality of Excel Web.

Time Synchronization BACnet clients such as EBI or 3rd-party BACnet front-ends, can time sync the Excel web controller via the standard time sync or UTC time sync BACnet service. When having multiple Excel web controllers on a network without any BACnet client being the time master, the time must be set for any controller separately and correctly before downloading the application.

EBI Compatibility The Excel Web controller communicates with BACnet front-ends only.

Supported BACnet front-ends are:

•EBI / SymmetrE Software

For more information, please refer to the following software release bulletins:

−EBI R300.1 with Excel Web / BACnet Software Update

−SymmetrE R300.2 with Excel Web Software Update

−EBI / SymmetrE R310.1 or later

•XFI Software

The XFI has not been tested yet with Excel Web, but supports BACnet functionality.

Operation and Application Software

Programming The Excel Web® is freely programmable using the CARE Engineering Tool and is thus ideal for all Building Control and Building Management tasks.

This allows making use of standard, pre-tested and pre-documented application and control strategies.

Application Control Four selectable control loop speed classes (multitasking) with defined cycle times and switching tables allow tailored and highly effective applications control.

User Administration Your control system is protected by defined user access rights. This ensures that only authorized persons have access to the system data. There are six pre-defined user levels. The predefined user levels are arranged hierarchically and the sequence with descending priority is as follows:

•System Admin (128)

•Project Admin (115)

•Building Engineer (96)

•Operator (64)

•Tenant (32)

•Guest (0)

Excel Web® allows the definition of up to 128 user levels by default. The above mentioned user levels are available. Each user level can have different read and write rights assigned, e.g. Display Communication Settings, Create and Delete Calendars, Change clock settings, etc. Several users with individual passwords can be defined for each user level.

NOTE: There is no limit to the number of users per user level.

Datapoints Datapoints are the basis of the Excel Web – BACnet system. Datapoints contain system-specific information such as values, status, limit values, and default settings. The user has easy access to datapoints and the information they contain.

The user can recall and modify information in the datapoints.

Alarm Handling Alarm handling is defined and realized in the application.

BACnet alarming

On datapoint level, alarming is done by the BACnet intrinsic reporting service.

The following point changes may generate alarm messages:

•Exceeding limit values (analog points and pulse converter point)

•Changes of state (binary and multi-state input and value datapoints)

•Faults (due to, e.g. LON communication errors or e.g. sensors breaks)

Alarming is further supported by notification class objects, which contain information required for the distribution and segregation by time and addresses of alarm/event notifications within a BACnet system.

Notification class objects allow up to 256 alarm priorities. By default, CARE provides 3 notification class objects matching the EBI alarm priorities:

•Urgent

•High

•Low

IMPORTANT

The internal ring alarm buffer takes max. 100 alarms.

Excel Web does also support the BACnet algorithmic alarming service.

The algorithmic alarming uses the standard BACnet “Event Enrollment Object” and is used to provide the following functionality:

•Warning limits for analog datapoints (Min. and Max. warning limits, in addition to the Min and Max Alarm limits)

•Alarming for datapoint change between “auto” and “manual”

•Alarming for missing or late acknowledgement of alarms

•Maintenance alarming, based on elapsed runtime of datapoints or number of state-changes of datapoints.

•Alarming for unsuccessfull transmission of Email alarms

•Alarming for stopped or started plants within Excel Web

LON alarming

As LON does not know "devices" but only NVs, I/O module alarming must be realized by mapping a particular NV to the appropriate "alarm" datapoint in CARE. Then for the alarm datapoint, the alarm settings are to be defined as usual.

Remote LON Commissioning Excel Web Controllers on a LON bus can be commissioned remotely via LAN / WAN using CARE or Excelon (can be used as LonWorks protocol analyzer via LAN).

Time Programs Time programs comprise schedules and calendars.

Schedules

Schedules are daily and weekly time programs.

Whenever you want, you can use schedules to enter the setpoint or status for any datapoint.

Schedules are assigned to plants. Each plant of a controller can have multiple schedules assigned and each schedule can command datapoints of that plant.

Each schedule specifies a list of datapoint properties to command (switchpoints) on a weekly basis. The week program defines the normal daily activity of the system by specifying which switchpoints are to be commanded each day of the week. The week program applies to a definable time period. There is only one-week program per schedule.

Schedules offer 16 write priorities that define the priority for writing to the present value of output and value datapoints. Note that only priorities 9 to 16 are allowed in the controller.

The write priority applies only to the present value property of virtual points and output points. The write priority is ignored for all other types of properties.

USER GUIDE

For every schedule (week program), specific programs called exceptions can be created. Exceptions have higher priority than the week program and will overwrite the week program for a definable time period. Exceptions can be one of the following four time periods:

•Specific Date

e.g. Christmas Eve or 5.5., the whole of May, or the whole year of 2004

•Date Range

e.g. Summer holidays from 29.7-7.9.2004

•Recurring Event

e.g. every last Friday of every month

•Calendar Reference

A project-wide calendar provides dates, e.g. regional holidays and public/religious festivals or any other particular date. The time period can be a specific date, a date range or a recurring event.

Calendars

Calendars contain exception days or periods, e.g. Christmas, holidays. Calendars are valid for the whole project, and are executed in each controller but apply only to those schedules, which reference calendars. Changes in multiple particular controller schedules can be quickly made by simply changing a calendar in one controller. Thus project-wide scheduling can be influenced.

Trending Trending can be performed via the Excel Web HTML Interface residing on any PC platform and via BACnet clients. Trend data is stored on an 2 MB integrated Flash memory which can hold a maximum of 64,000 trend records distributed among 125 trend log objects. In addition, three trend log objects are used for LON statistic trending. A single trend log object can include max. 2.880 trend records (max. trend buffer size). One trend record equals 30 bytes. Extended trend memory is possible by using a 3rd-party standard Compact Flash card or micro drive. Trend data storage can be in ´Ringbuffer` mode or in ´Stop When Full` mode. Trend data are dynamically created in the controller and can be saved in a .CSV file.

Trend data have unlimited lifetime and survive an application download. Trend objects must be explicitly deleted via Excel Web HTML Interface or BACnet. This deletes also the corresponding trend records. The trended object may be a local or a reference point in the same controller and the trended property may be integer or floating point, e.g. point value, point state, alarm limit, time stamp.

Trending via BACnet Client

BACnet clients like EBI will use the BACnet ´read range service` to readout trend values from the Excel Web controller. Trend recovery for BACnet clients, specifically EBI and SymmetrE optionally provide an automated recovery mechanism which allows to "backfill" missing trend data on the BACnet client side with trend values from the Excel Web controller.

Controller Based Trending A Compact Flash Card (type 1 or type 2) or micro drive allows memory extensions for the purpose of expanding integrated trend memory and increasing historical data storage. The integrated on-board trend memory allows saving of max. 64.000 trend values.

Protocolling In the context of the Excel Web controller, "protocolling" means creating a log of the values or states of the datapoints, which have been assigned to this particular Excel Web controller. Using the Excel Web HTML Interface, the user must place the corresponding datapoints into "trend". If, at some later point in time, i.e. after lengthy operation, a protocol of the Excel Web controller's history is desired, the corresponding trend data can be generated, viewed, and downloaded (in CSV format) via the browser interface. For the storage of larger amounts of trend data (more than 64,000 trend entries – corresponding to approx. 2 MB), a CF card or micro drive can be used. The trend data can even be downloaded into a BACnet client if this client supports this BACnet service.

When connected to the Excel Web controller via Internet Browser, all other Excel Web controllers of the same project can be operated without the necessity of a new login.
