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

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

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.

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.

datapoint.
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.
