Local communication options
The analyzer supports local communication for operator access through an explosion-proof port MMI
port. The available standard option is a USB port. An RS-232 port is optional (note that this is
considered a legacy interface with a lower communication speed; additional adapters may be needed
for connection).
Local connection during initial installation is also available through the Ethernet port, but this requires
access to the terminal board inside of the analyzer (removal of the enclosure’s rear cap is required). It
is recommended that initial connection for commissioning is made through the USB port.
All port types are supported by the user interface (PCCU32).

Embedded software and user interface
The embedded software and host-based user interface (UI) provide options to configure, operate, and
collect data from the analyzer.
3.1
Embedded software
The analyzer’s embedded software consists of the operating system (OS) and the Flash (Application)
components. The flash compiles all applications required for the operation of the analyzer. The
analyzer supports upgrades of either or both components depending on the features or fixes
introduced with periodically released update software packages.
The software supports the following:
Audit quality historical data
Multiple calculation options
Selectable engineering units
Analysis reporting
Operational alarms
Communication protocol selection
Bi-level security (access to analyzer is protected by pass code or Role Based Access Control
[RBAC] admin-defined user credentials)
Options for configuration, access, control, reporting and data communications are available on the
user interface (PCCU).
3.2
User interface (PCCU32)
PCCU32 is the host-based user interface to the analyzer. It runs in a Windows
®
environment and
offers options for access, configuration, control, reporting, and data communications. It supports the
following:
Communication to the analyzer through local or remote connections. It supports standard
serial, USB, and Ethernet connections.
Several device operation and maintenance utility functions such as a loader for embedded
software updates, device configuration and data backup, and historical data collection. All
functions are available through local or remote connections.
Provides online help. Context sensitive help topics display by clicking
Help
on each operation
or configuration screen associated with the analyzer.

3.3
Audit quality data
The embedded software supports an historically accurate file system that uses date- and time-
stamped events to create an audit quality data structure. The analyzer compiles historical data that
can be used for custody transfer needs, verify analyzer operation over time and provide a limited
amount of historical data as a backup for communication failures.
The device can collect, analyze, and retain (default) stream data for the last 480 analysis cycles,
retain the last 35 days of daily stream averages, the last 480 diagnostics reports, the last 480 alarms
and the last 480 events. This default can be reconfigured by the user from PCCU32. The default
configuration is as follows:
Analysis cycles for the last 480 analysis cycles (default):
