1.2.4 Communication Options
Data Communications
An operator can configure and troubleshoot the O
2
Probe system in one of two ways:
1. Using the 6888Xi Advanced Electronics keypad and display to access the following optional
advanced features:
• Probe configuration
• Fully automatic calibration
• Failure diagnostics
• Flame safety interface
• High temperature operation [above 700°C (1292°F) standard temperature].
• Stoichiometer feature provides the ability to indicate O
2
efficiency when the combustion
process goes into reducing conditions (0% O
2
).
• Programmable reference provides enhanced accuracy when measuring at or near O
2
level
(20.95% O
2
).
• Plugged diffusor diagnostics
2. Using the HART Interface. The 6888Xi’s 4-20 mA output line transmits an analog signal pro-
portional to the oxygen level. The HART output is superimposed on the 4-20 mA output line.
This information can be accessed through the following:
• Rosemount Analytical Model 375/475 Field Communicator - The handheld communica-
tor requires Device Description (DD) software specific to the 6888Xi. The DD software
will be supplied with many Model 375/475 units but can also be programmed into exist-
ing units at most Emerson Process Management service offices. See Section 4, Startup
and Operation, for additional information.
• Personal Computer (PC) - The use of a personal computer requires AMS software available
from Emerson Process Management.
• Delta V and Ovation Distributed Control System (DCS) with AMS-inside capability.
NOTE
The 375 Field Communicator must be upgraded to System Software 2.0 with Graphic License for
operation with the 6888Xi. The AMS software must be upgraded to AMS 8.0 or above.
Contact Emerson Process Management’s Global Service Center (GSC) at 1-800-833-8314 to upgrade
the 375 Field Communicator software to System Software 2.0 with Graphic License.
