The IEC/UCA 61850-9-2LE process bus communication protocol enables an IED to
communicate with devices providing measured values in digital format, commonly
known as Merging Units (MU). The rear access points are used for the communication.
The merging units (MU) are called so because they can gather analog values from one
or more measuring transformers, sample the data and send the data over process bus to
other clients (or subscribers) in the system. Some merging units are able to get data
from classical measuring transformers, others from non-conventional measuring
transducers and yet others can pick up data from both types.
