addVANTAGE Pro 6.4 Administrator Guide CHAPTER 1
addVANTAGE Pro Services over the Internet
Note: addVANTAGE Pro is compatible only with the A840 Telemetry Gateway running
the firmware release 3.8.0 or higher and the A850 Telemetry Gateway. You
cannot use an A730SD receiver to retrieve data into addVANTAGE Pro 6.4.
addVANTAGE Pro Services over the Internet
addVANTAGE Pro is built from the ground up to support the Internet. Apart from
the fact that all the data transfer protocols used by addVANTAGE Pro are
Internet-compatible, you can provide all of the data addVANTAGE Pro holds over
the Internet via the built-in web server. In addition, a limited amount of data
(last recorded tag values) can be provided to mobile phones via WAP (Wireless
Access Protocol).
Be aware that several conditions must be met before you can offer web services
over the Internet:
You need a fixed IP address and a valid Internet hostname in a domain
registered with an Internet registrar.
You need a computer able to support the additional load, depending on the
number of concurrent users your server will have to support.
•You need an always-on Internet connection offering sufficient throughput,
otherwise your customers will be frustrated with the long download times.
Depending on the number of customers and RTUs in your system Adcon
recommends following connection types (DSL, XDSL, cable, leased lines):
at least 128 Kbps for a small server with few users (up to 5)
at least 512 Kbps for a medium server with up to 50 users
at least a T1 line for a large server with more than 50 users
Note: Beware of asymmetric lines—the numbers given above refer to the throughput
for the upload channel.
You need a suitable license to support the number of concurrent users you
plan to allow.
How it Works
Keep in mind these issues when planning to offer data from addVANTAGE Pro
over the Internet:
Every user who accesses addVANTAGE Pro services over the Internet must
have an account already established.
Depending on the privileges you give to each user, you might need to
create the appropriate panels for them (Trend and Events viewers). You
might also need to add RTUs, tags, and extensions.
The users must have read access to the panels you want them to see.
For additional details about creating and administering accounts, see
“Administering Users, Groups, and Roles” on page 27. For creating panels, see
“The Trend Viewer” on page 62 and “The Events Viewer” on page 73. For adding
RTUs and tags see “Configuring the Data Acquisition Service” on page 50, while
for details about adding extensions see “Adding Extensions and Crops to an
Area” on page 81.
WAP Access
WAP access is automatically enabled in addVANTAGE Pro 6.4 and it is password
protected. The information accessible via WAP is limited and the users can
access only the last value recorded for each tag. However, you can disable
password protection for WAP access on your server.
To access the addVANTAGE Pro server via WAP, your users need to enter (and
store) a link similar to:
http://yourserver.domain.com:8080/wap?u=username&p=passwd
If the password protection feature is disabled, the link becomes simply:
http://yourserver.domain.com:8080/wap
After the link is entered in the cell phone, the user simply accesses it as a
normal WAP link. The navigation is limited to the areas, RTUs, and tags where
the user has access rights (if password protection is enabled).
