Monitoring a Small-Scale Power Generation System
Electric Control Panel Monitoring
Modbus RTU/ASCII to Modbus TCP
Industrial plants often have their
own power generation systems to
provide an uninterrupted power
supply. To enable continuous
monitoring, Modbus is commonly
adopted as a communication
protocol to transmit large volumes
of Modbus RTU monitoring
information from power RTUs, Intelligent Electronic Devices, and
meters, via industrial gateways to the process control system running
on a Modbus TCP network.
Modbus RTU/ASCII to EtherNet/IP
EtherNet/IP is a communications
protocol developed by Rockwell
Automation, and is widely used in
many large-scale power systems
for remote monitoring to ensure
reliable performance and energy
control. Although ControlLogix
PLCs support Modbus modules
for connecting a Modbus RTU to EtherNet/IP, it may be too expensive
to modify the PLC code and a convenient rack slot may not be
available. For this reason, gateways have become a popular way to
achieve Modbus communication requirements.

Applications
Modbus RTU/ASCII to Modbus TCP (cellular network)
DNP3 Serial to DNP3 IP (cellular network)
Pipeline networks can stretch for
hundreds of miles. To decrease the
risk of explosions and leakage, a
reliable remote monitoring system
that includes meters and PLCs to
manage onsite operations is an
absolute must. As a result, many
systems now use a cellular network to transmit Modbus RTU data
from field devices back to the SCADA Modbus TCP network. In these
situations, a Modbus gateway that supports cellular transmissions and
VPN tunneling is required to provide a reliable and secure connection.
PROFIBUS to Modbus TCP
Drilling for oil and gas involves many
risks, and even a tiny mistake could
cause leaks or spills that result in
serious accidents and contribute to
environmental pollution. To prevent
accidents and ensure accurate
drive-to-drill operation, operators
use industrial gateways to bridge
Modbus TCP networks with PROFIBUS-based meters or drives for
real-time remote control.
