Device networks overview

PME is a software application that processes, stores, analyzes, and displays power system data and information. PME collects the source data from devices that are installed in the electrical system that is being monitored. Each device must be connected to a communication network through which the software initiates the data retrieval.

Examples of monitoring devices include:

• Power and energy monitoring devices
• Contactors and protection relays
• Circuit breaker trip units
• Smart panels
• Power quality mitigation equipment
• Programmable Logic Controllers (PLCs)

PME supports the following communication protocols:

• Modbus™ TCP
• Modbus™ RTU
• ION™
• OPC DA

For a device to be compatible with PME, it must support one of these communication protocols.
