2. PROGRAMMABLE LOGIC CONTROLLER (PLC)
Richmond Engineering Works excels at custom designing and
programming PLC applications to meet the needs of any DCS or
SCADA system. All of our PLC projects are engineered to meet your
specific requirements, including: Full Integration of all
electrical equipment, Human-Machine Interfaces (HMI’s),
“Expert Systems” with self diagnostics, motion control
packages, process monitoring, report generation, alarm
panels, advanced machine control and remote operation,
monitoring and troubleshooting.
HUMAN-MACHINE INTERFACE (HMI)
Take control of your factory automation with a custom engineered HMI from
Richmond Engineering Works. By providing clients with state-of-the-
industry HMI solutions, we help companies increase performance, minimize
down time and reduce waste. Our engineering staff offers you the security of
a proven track record designing HMI systems for numerous companies and
applications. Build it, make it or move it like never before with an HMI
system that meets all of your plant floor and machine control needs.
• Environmentally Sealed Touchscreen Controllers place
complete control and full information at the user’s fingertips.
• Push button and switch replacement.
• Alarm Messages warn operators of problems before they
occur.
• Operator Help Messages assist users with pop-up
instructional, system training and corrective action messages.
• Active graphics fill, scale, rotate and change color to verify
status.
• Animation screens show motion and position.
• Statistical Process Control Features monitor and adjust any process to ensure
that it remains within its specifications.
• Recipe and Batch Management Screens allow users to create a master recipe
and permit on-line adjustments to be made without shutting down the process.
• Historical Trending and Reporting Functions collect, archive and display
process data on easy to-read charges and graphs.
• Remote Networking Connections make it possible to transmit, display and control data to any
specified station.
• Remote Telemetry Systems communicate with DCS systems, PLC’s RTU’s, loop controllers, bar code
readers, RFID tag readers, scientific analyzers and more.

3. CLAMSHELL / GRAB UNLOADER UPGRADES
• Replace obsolete DC Drives and wound rotor
motors with State-of-the-Art Digital Drives and
remanufactured Mill Motors.
• Upgrade to a PLC Based Control System for
improved system reliability and increased diagnostics
capability for the operators.
• A new Control Cab will give the operator better
visibility, modern controls and more room for safer
operation.
• A new Operator Chair will help to save cab room
by incorporating new, smaller controls into the
chair. The ergonomically designed chair along with
new joystick controls will help to reduce operator
fatigue assuring safer operation.
• A new HMI / MMI will give the operator the
ability to see virtually all machine functions from a
single location. This will aid in operations,
maintenance and overall safety.
• A new Electric House, located on the shore, will contain the new PLC, DC drives, isolation transformers
and MMI station. By locating the electric house on-shore, the outage length and the installation costs
will be drastically reduced. The old equipment will be abandoned in place eliminating the costly price
of removal.
• New Vector Drives and Motors along with gearboxes
on the barge haul system can help to increase machine
throughput and help with smoother machine operation.
The barge haul controls can be incorporated into the
machine PLC.
• Where it is not practical or financially feasible to replace
the M-G set, a new Field Control Regulator can be
used to replace the obsolete field controls such as an
outdated Amplidyne® controller.
• Reduce wiring maintenance issues by upgrading with a state-of-the
art DeviceNet platform. With the installation of remote I/O and
using DeviceNet Communication, multiple runs of wire are
reduced to a single communication cable.

COAL YARD UPGRADES
• Upgrade to a PLC based
Control System to replace
the old style electro-
mechanical relay controls.
In addition to saving space
and increasing system
reliability, a PLC offers
features such as remote
communication, diagnostic
capability and the ability to
interface with the plant DCS
system. It is proven that a
PLC based control system is
more economical than a
DCS based control system
for coal yard operation.
• A new HMI Operator Station will give operations a central location for monitoring and controlling yard
operations. Remote MMI Stations can also be incorporated giving plant personnel viewing access (but not
control) from multiple locations within the yard. Maintenance can use the same MMI stations to help
troubleshoot and pinpoint the exact location of a problem. This will drastically reduce the time and
duration of a repair.
• By replacing chain driven gearboxes with direct drive motor/gearbox assembly, increased reliability of
the conveyor system will be realized. In addition, no time will be spent repairing, replacing and greasing
the drive chain. The current sensors on the new motor will enable the operators to monitor motor amp
draw and prevent an unexpected motor failure.
• We can design and upgrade a new Warning and Safety System including Warning Lights and Horns,
Belt Alignment Switches and Pull Cords.
• By using Fiber Optic Communications and Radio Modems, all of the coal yard operations and
monitoring can be centrally located. This could include every process from where coal enters the plant to
the bunker filling operations.

ANCILLARY SYSTEMS UPGRADES
In addition to the primary coal
handling equipment, Richmond
Engineering Works can design and
engineer upgrades to power
plant ancillary systems as well.
Projects typically involve a conversion
from electro-mechanical relays to a
PLC based control scheme with
existing pilot devices, actuators and
sensors being integrated into the PLC
controller. These systems are
engineered to operate independently
but can be networked with other plant
systems. Graphical Human-Machine-
Interfaces (HMI)’s whether mounted
locally or in the control room, allow
plant personnel to better monitor and more accurately control the system operation as well as help the
maintenance personnel locate, diagnose and correct problems quickly and efficiently.
Upgrades have also included the use of interactive operator stations, AC drives, motor / gearbox,
integration with existing sensors, radio links, fiber optics and interfacing to plant controls
through the use of various types of communication networks.
