Study Notes

Logging Requirements

PME requires accurate historical data from devices, to create reports, dashboards, and visualizations
Historical data is saved in three locations: Onboard device memory, Panel Server, and PC-based logging in PME

Onboard Logging Configuration

PowerLogic devices have pre-configured onboard logging, which can be changed using ION Setup
Devices with onboard memory can log historical data including critical data such as power quality, revenue, and energy
Basic devices may not have onboard memory, requiring either a data logger, energy server, or PME to log historical data

Data Logger Configuration

Panel Servers have pre-configured device driver templates for basic data logging, such as Active Energy Into the Load (kWh)

PC-based Log Configuration

PC-based logging can be configured for Modbus devices, including those with onboard logging to capture additional measurements
PC-based logging can be configured for all devices of a specific type, for an individual device, or using the Virtual Processor (VIP)
The Virtual Processor (VIP) allows for highly-configurable logging requirements and can be assigned to Logical Devices for better visibility

Blended Logging

Devices with limited onboard memory may combine onboard logging for important measurements (energy) and PC-based logging for less important measurements (currents, voltages, power, demand, WAGES)

Key Points to Remember

Power Monitoring Expert can collect historical logs through onboard device logging, a data logger, and PC-based logging
Device logging is enabled in the devices
PC-based logging can be configured for all devices of a specific type or for individual devices
