Instruction for the
Cutler-Hammer Type MPCV
Network Protection Relay
Protocol Translators
MINT II — converts INCOM protocol format to RS-232 data.
1. It provides access to all parameters monitored over
the PowerNet network.
2. Supports up to 10,000 feet (3,048 m) distance and
1,000 relays.
3. It can also be applied as an interface between telephone
lines, dial-up modems, fiber optic line drivers, radio
frequency or wireless modems.
PMCOM5U — compact version of MINT II, known as mini-
MINT. It is a portable industrial grade, wall-mount MINT that
can be plugged into any standard household 120 Vac outlets.
EMINT — an Ethernet MINT that provides direct conversion
from INCOM protocol to TCP/IP messages.
CONI Card — a computer operated network interface
card that can be installed in a computer or into a NetLink.
It converts the INCOM protocol to ISA (Industrial Standard
Architecture) format. It also maintains backward compatibility
with existing IMPACC systems. Supports up to 10,000
feet distance and 1,000 relays.
NetLink — a computer-based device that:
1. Translate INCOM into Standard Ethernet TCP/IP
messages, or ModBus RTU.
2. Acts as a data logger to store events and trend
information.
Commercial Translators
There are devices available in the market that can translate
INCOM protocol format to:
1. SES92 format
2. DNP3 format
System Capacity
The Master PC (device server) can support:
1. Multiple MINTs up to 32 serial ports (RS-232) using
port expander
2. Four CONI cards
The NetLink can support two CONI cards (or two INCOM
networks) that communicates to a total of 200 devices.
System Protection
Due to relatively harsh industrial environments, Eaton
has designed a device known as the INCOM Coupler. It is a
filter, which effectively isolates common mode power line fre-
quency signals that could occur when directly connecting
ground potentials from distant locations such as from
vault-to-vault connections. The ground differences would
be negligible at normal operating conditions but could rise
greatly during fault conditions depending on the specific
“earthed” connections. It provides protection to all equipment,
hardware accessories and cables connected to the communi-
cation system from:
1. High levels of surge transients noise.
2. Ground Potential Rise up to 10 kV to 20 kV during
fault events.
3. Incorrect or accidental connections of ac source across
the twisted pair.
