Eaton Power Xpert 1000

The Eaton PXM1000 software is designed for the PXM 1000 series power meters, providing a user-friendly interface for real-time monitoring and data logging. This tool enables continuous monitoring of multiple parameters, facilitating energy saving and power quality analysis, and allowing users to maintain the meter on a real-time basis.

Function Description

The software's core functions revolve around device communication, monitoring, data logging, and configuration.

Basic Monitoring:

The PXM1000 software allows users to add new connections and devices, set connection parameters, and then connect to these devices to read measurement data. Users can view measured values by navigating a menu tree, with the displayed content varying based on the device type. The connection can be stopped at any time.

Device Management:

Users can add new devices and manage existing ones. If an unused device window is present, it can be selected to make the device status "available" by clicking the Device Properties menu or icon. Unneeded device windows can be deleted. The Device Manager provides a comprehensive overview of all available devices, displaying their detailed communication status, including the total number of devices, normally communicating devices, communication failures, log-enabled devices, and log failure totals. Counters can be reset, and device properties can be modified.

Data Logging:

A critical feature is data logging, which requires prior setup. Users can access Data Log Settings through the Settings menu or a dedicated icon. Within these settings, a device list shows all devices in data logging mode, allowing users to enable or disable logging for each. Users can select one or more logging items, such as Real-Time Metering, Demand, Energy (Real-Time), Energy (TOU), Pulse Input, DI Counter, Analog Input, Harmonics (THD), Harmonic Spectrum, and Phase Angles.

Logging options include setting the data logging interval (in minutes or seconds), defining when a new log file should be created (either when the file is full, with a maximum of 64,800 rows, or after a specified duration), and choosing the log file format (.txt, .csv, or .xls, with .txt recommended). Users can also set column display names for Pulse Input and Analog Input items. The log file name can be customized, or the default name can be used. A specific folder location for log files can be set, with D:\MonData in the PXM1000 installation directory being the default.

To initiate data logging, users must connect to the device and then select "Start Data Logging." Logging can be stopped at any time. Log files are stored with names consisting of the device description, type, port (Serial mode) or IP address (Ethernet mode), device address, and logging start time (YYYYMMDD format).

Import/Export Device Profile:

The software supports importing and exporting device profiles. A device profile, containing settings, can be loaded into the current active device window. To send an imported profile to a device, users must first connect and then use the "Import and Update Device" tool. Current window settings can be saved as a file via "Export Device Profile."

PXM1000 Series Specific Functions:

Readings:

Energy (PXM1000): Users can view and modify energy values.
Voltage Spectrum, Current Spectrum (PXM1000): Displays harmonic spectrums for voltage and current. If harmonics are 0%, no display is shown.
Sequence Component (PXM1000): Shows the angle between IA and VA, with a broken-line circle indicating 100% of the full range. It displays full range indicators, vector expressions, and angles between IA and VA.
I/O Modules (PXM1000): Displays AO parameters as real values and AI parameters as numerical values (range: 0-4095).
Data Log (PXM1100): Provides three ways to retrieve logs: "read newest 50 records," "read one window," and "read 1000 records." It displays data log statuses, allows selection of log types, and shows the data area.
Waveform Log (PXM1300): Allows users to retrieve waveform data corresponding to selected items. After reading, the data column remains, and a waveform graph is automatically drawn. Users can save selected waveform data as .txt, .csv, or .xls files for analysis. The waveform graph displays capture time and reason, capture time when conditions are met, values at the current timestamp, and a movable time label.

Settings:

General (PXM1000): Configures communication channels (Protocol, Address, Baud Rate, Parity), wiring (Voltage, Current, PT and CT Ratios), I L1/L2/L3 Direction (Positive/Negative), Security (Password), Demand Type (Sliding Window Demand, Thermal Demand, Averaging Interval Window), DO Energy Pulse Constant (Watt, VAR), and Other settings (Turn On the Backlight, Energy Type, Energy Reading, VAR/PF Convention, VAR Calculation Method). In serial connections, the password is visible as a decimal number. In network connections, it's displayed as '*' and can be changed via a dedicated "Change Password" window.
I/O Modules (PXM1000): Configures DI Type (State, Counter), DO Type (DO Energy Pulse Mode, DO Output), Alarm (Pulse Width), and AO Input/Output Transfer Curve (Input Range, Output Range, Single Slope). Note that AO Transfer Curve settings have no unit, with all units displayed in the Raw Channel of the AO area.
Alarm (PXM1000): Allows setting alarm limits (Setpoint) for various channels (e.g., Frequency). The alarm channel unit is displayed, but the setpoint value is unitless.
Data Log (PXM1100): Allows programming up to 114 parameters per log, with a total size not exceeding 100 sectors (64k bytes).
TOU (PXM1200): Configures Time-Of-Use settings, including TOU Seasons (MM-DD ID for Months, Days, and Schedule Number) and TOU Schedules (HH-MM ID for Hours, Minutes, and Tariff Number).
TOU Holiday (PXM1200): Configures holiday settings, including Start Year, Ending Year, and specific holiday dates (MM-DD ID).
Pulse Input (PXM1000): Configures DI Type (State, Counter), Name, Category, Unit, and Ratio. When DI Type is "state," options are disabled; when "counter," they are enabled. An "Advanced Option" button allows defining Category and Unit.
Analog Input (PXM1000): Configures Name, Category, Unit, and Ratio for analog inputs. An "Advanced Option" button allows defining Category and Unit.
