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

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

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.

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.

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 ignore

d for all other types of properties.

EXCEL WEB 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 contain exception days or periods, e.g. Christmas, holidays. Calendars

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 3

-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.

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.

USER ADMINISTRATION

37 EN2B-0289GE51 R0709

EXCEL WEB USER GUIDE

The user administration (user access manager in CARE) is used for defining user

rights according to the required functions. These definitions are done in CARE firstly by creating the users and issuing the functions they should have permission for in the Excel Web HTML Interface. In addition, the user administration (user access manager) is used for defining the language and decimal places of values the Excel Web HTML Interface should display. User rights can be changed in the Excel Web HTML Interface dependent on the predefinitions of the user in CARE.

Access Rights List An access rights list for a complete project will be created by assigning predefined

User Profile For each user within a project, a user profile with the following properties will be

NOTE: All users can operate all controllers of a project.

Changes in the user administration will be automatically synchronized

user levels to all executable functions (access rights) of the Excel Web HTML Interface. An access rights list may look as follows:

Access Right User Level

Change Communication Settings System Admin Create and Delete Schedules Building Engineer Create and Delete Trends Building Engineer Display Diagnostics Tenant

The predefined user levels are arranged hierarchically and the sequence with descending priority is as follows:

• System Administrator (128)

• Project Administrator (115)

• Building Engineer (96)

• Operator (64)

• Tenant (32)

• Guest (0)

Example:

When assigning ´Operator` to ´Create & Delete Calendars`, a user having a user (access) level below ´Operator`, for example ´Tenant` or ´Guest`, is not able to create and delete calendars. A user having a user level equal to or higher than ´Operator`, for example ´Building Engineer` or ´Project Admin` is able to create and delete calendars.

NOTE: When creating a project in CARE, the System Admin level is

created:

• User name

• User (access) level

• Language

• Decimal places

• Password

• Access rights

• Email address(es)

A user is identified by its user name. One of the predefined user levels will be appropriately assigned to the user (name).

Due to the access rights list definitions, this assignment automatically determines the set of access rights, which the user is allowed to execute in the Excel Web HTML Interface.

All users having a user level higher than or equal to the assigned user level will have this access right enabled in the Excel Web HTML Interface, all others will not.

DATAPOINTS

An Excel Web® controller supports up to 600 physical datapoints and an unlimited number of value datapoints.

A datapoint has different properties according to its type. Properties are displayed and can be modified via a standard browser on operator interfaces such as laptops, desktop PCs, or panel PCs. Properties contain information about the given datapoint. Among many more, this information could be:

• Present value

• Transition events

• Descriptions

• Input limits values

• Operating status

• Elapsed run time

The following sections provide more-detailed information about the different kinds of datapoints and datapoint properties and explain which properties are assigned to which datapoints.

In addition, the Excel Web controller has two Integrated I/Os:

Binary Output

• potential-free relay, SPST (single pole single throw), normally open, 24 Vac +/20%, max. 2 A permanent load

• application-driven

• 1 "active" LED, illuminated when contacts closed

The binary output can be used for connecting an alarm buzzer.

Binary Input

• potential-free contact, max. 36 Vdc

• application-driven

• 1 "active" LED, illuminated when contact closed

Physical Datapoints

Physical datapoints are inputs and outputs attached to hardware devices like sensors and actuators.

The following are examples of physical datapoints:

Analog Inputs NTC, PT 1000, PT 3000, BALCO Sensors (PT 3000/BALCO), standard 0...10 V / 0

Analog Outputs Outputs with a continuous 0...10 V output signal for controlling continuous actuators Binary Inputs Inputs for processing voltage-free signals (switches, contacts, counters). Binary Outputs Outputs for driving three-position actuators, for example, a damper motor; two

Multi-State Inputs Inputs used for equipment feedback (Automatic, On, Off) Multi-State Outputs Outputs controlling multi-stage fans (0, 1, 2, 3) Pulse Converter Digital inputs for processing pulsed signals up to 20 Hz (depending on I/O module

Value Datapoints

Value datapoints are values (intermediate results and parameters) computed while the application program is running. In contrast to physical datapoints, value datapoints are not directly connected to hardware devices.

A typical example of a value datapoint is a room temperature setpoint.

Access via datapoint name During system operation, you may need to access these values. To simplify this

Analog Value Datapoints Analog value points are software points containing an analog value in the user

Binary Value Datapoints Binary value points are software points containing a binary value in the user

Multi-state Value Point Multi-state Value datapoints allow switching 32 stages (including the “off stage“) of

process, you can include value datapoints in the datapoint list, where you can access them directly via their datapoint name.

Like physical datapoints, value datapoints, too, can have different properties; for example, they can specify a manual value, set minimum and maximum values, or log trends.

The following are types of value datapoints:

• Analog value points

• Binary value points

• Multi-state value points

For example, logical AND operation: The AND operation provides a logical 1 output when all input conditions are also logical 1. Otherwise the output is a logical 0. If the user program contains such an AND operation on different input conditions, then the output could be available as a binary value datapoint.

physical digital inputs or outputs. Depending on the number of stages, the multistate value point provides up to 32 editable stage texts, e.g., stage 1, stage 2, stage 3, etc, to be edited in CARE.

Reference Datapoints

If your control and monitoring system contains more than one controller, the controllers communicate with one another via the BACnet bus. This enables one controller both to read and set the datapoints from other controllers, and to read values

of 3

-party BACnet devices of the project and external BACnet devices which are

not in the project.

This data communication is realized via so-called reference input/output points. They always originate in or write to another plant and may originate in or write to another controller.

On the EBI, alarms will be graphically indicated by blinking in the status line and shown in the alarm summary. Events will not be indicated in the status line and will be shown in the event summary.

The notify type can be defined and changed in CARE. In the Excel Web HTML Interface, the notify type (alarm type) is displayed only.

For all notification classes, notify type ´Alarm` must be used.

Equivalent Alarm Value

Defines the alarm condition of a binary input or value point when an alarm should be reported in case of binary input changes. The alarm condition can be either the active state or the inactive state of the point e.g. 0 or 1, ON or OFF, Up or Down. If the present value is equal to this condition for at least the alarm delay time, then an OFF-Normal event is generated. In addition an alarm delay can be entered.

The BACnet instance number is part of the internal BACnet addressing in every BACnet system (BACnet communication). The BACnet instance number of datapoints is not visible in the Excel Web HTML Interface and the user does not need the BACnet instance number in order to operate the Excel Web controller.

The BACnet instance number of a device object is visible in the Excel Web HTML Interface.

USER GUIDE EXCEL WEB

When creating objects in CARE such as datapoints, schedules or calendars, CARE assigns an instance number to each object. The instance number is unique within the same object type but the same instance number may also exist in other object types. The instance number of the device object is unique on the whole BACnet network.

The following table shows examples of instances, which CARE automatically assigns to the corresponding BACnet objects while they are created:

Object Type Instance Number

Analog input 1 1 Analog input 2 2 Analog input 3 3 Analog input 4 4 Analog input 5 5 Binary input 1 1 Binary input 2 2 Binary input 3 3 Binary input 4 4 Binary input 5 5

The instance number in combination with the BACnet object type information is one method in creating and adding a 3

party BACnet device to the BACnet bus (see

also "BACnet Object ID" section).

This information must be provided by or to the project engineer/vendor who is responsible for the 3 is responsible for integrating the Excel Web controller into a 3

party BACnet device to be added to the CARE project, or who

party BACnet

system.

NOTE: In Europe it is common using the EDE data format for interchanging

information between BACnet objects. For further information, please access the BACnet Interest Group Europe e.V. at:

The BACnet object type is part of the internal BACnet addressing in every BACnet system (BACnet communication). The BACnet object type is not visible in the Excel Web HTML Interface and the user does not need the BACnet object type in order to operate the Excel Web controller.

In the BACnet standard, BACnet objects are classified in types.

Example:

Analog inputs are of BACnet object type "analog input(0)", binary inputs

are of BACnet object type "binary input(3)", devices such as the Excel web controller and 3

party BACnet devices are of BACnet object type

"device(8)”

The BACnet object type information in combination with the instance number is one method in creating and adding a 3rd party BACnet device to the BACnet bus (see also "BACnet Object ID" section).
