PRODUCT DESCRIPTION
and PTP (according to IEEE Std. 1588-2008 or IEC 61588), and it allows access to the relay via any standard web browser
(M60 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet port. The Ethernet port also supports the
Parallel Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when purchased as an option.
The EnerVista UR Setup software suite contains an automatic configurator for motor starting settings. The configurator
automatically populates settings and operands for input relays, output relays, trip bus, AC inputs, and signal sources based
on user requirements and the relay features.
Settings and actual values can be accessed from the front panel or EnerVista software.

The M60 uses flash memory technology that allows field upgrading as new features are added. Firmware and software are
upgradable.
The following single-line diagram illustrates the relay functionality using American National Standards Institute (ANSI)
device numbers.
