The Ultra SlimPak II Communications Interface adds functionality never before found in a signal conditioning system. A single WVC16 interfaces with as many as 32 Ultra SlimPak II devices by means of an internal infrared communications link. Through an Ethernet link in the WVC16, the information can then made available over the user's intranet. This powerful combination allows the user to view process data on a near real time basis, perform data logging functions on specified modules, view diagnostic information, and (under certain conditions) calibrate the modules remotely.

The WVC16 can send email messages to people who might need to be notified when an alarm condition exists. It can also send an email message letting maintenance personnel know when it's time to perform calibration checks. All of this functionality is made possible by a signed Java applet which is (transparently) downloaded to run on the client's computer. Using an applet rather than a traditional web page allows data to be updated in near real time. The applet provides access to the signal conditioner's data, which includes:

• Module configuration summary

• Module configuration editing

• Diagnostic/warning status

• Alarm setup & status

• E-mail setup, editing & address book

• Process variable viewing

• Data logging capabilities

All memory to support the signal conditioner's historical data is battery backed. The web pages and all email messages are stored in non-volatile memory.
