Walchem WebMaster ONE Instruction Manual page 33

Currently the WebMasterONE has only limited functionality for the local display and
keypad. ALL of the programming must be accomplished using a computer.
You will be able to calibrate all sensor inputs, change access codes, and enter the information
necessary to communicate with the WebMasterONE via an Ethernet connection or via the
modem over the Internet (if a modem card is installed in the controller). If neither of these
communications options are installed, you must use an USB connection to a PC for
programming. You may set most set points with the keypad, but you may not change
operating modes (for example, you may change the pump on time for a time-based add, but
not the time of day; nor can you change from a 1 week cycle to a 2 week cycle).
If you have a stand-alone controller with no communications, but you do have a computer to
connect to the USB port on the front panel of the controller for programming, go to the section
below called "Connection via the USB Port".
If you have a controller that is equipped with a modem, then you can take full advantage of the
WebMasterONE. The controller is like a web server. Once you set up an Internet Service Provider
(ISP) account for the controller, you can "surf" to the controller from any web connected computer
to access data or reconfigure the controller. The controller can also contact you, by email or pager,
in case of trouble. In this case, a dedicated analog phone line that does not go through a company
switchboard for the controller must be provided. For details, go to the section below called
"Remote Modem Access: Shoulder Tap." The ISP information must be entered into the controller
via the USB port, or via the local keypad before attempting a Shoulder Tap connection.
If you have not yet set up an ISP account and wish to program the WebMasterONE from a remote
location, or if you just prefer the "old fashioned method" of direct modem-to-modem
communication, go to the section below called "Direct Modem Access: Direct Tap."
If you have the Ethernet connected, then the controller can become another PC on the network.
You can use your web browser software, enter the controller's address (assigned by your network
administrator) and access data or reconfigure the controller. You will need to have a network node
nearby to connect your WebMasterONE. See the section below called "Ethernet Connection to
LAN".
You may also use the Ethernet card in your laptop to communicate with the Ethernet card in the
WebMasterONE. This requires a special null (crossover) cable and the Ethernet parameters must
be programmed into the WebMasterONE using either USB or the local keypad. Refer to the
section below called "Direct Ethernet (for an WebMasterONE not connected to the LAN)."
Uploading Configuration Files
You can save all of the set points from a previously programmed controller, and then upload the
same set points into another controller. If you have already downloaded a configuration file from a
previously programmed controller, you can upload that file to this controller in order to make all
the set points the same. If you want to save the set points of this controller for use in future
controllers, or want to program this controller using a stored configuration file, refer to section
6.48 for specific instructions.
See the appropriate section above, depending upon how you plan on uploading the configuration
file; via a laptop connected to the front panel, via modem, via Ethernet connection, or via local PC
connected to the USB port.
