Practical Fundamentals of E-Manufacturing, MES and SupplyLiving Online
Supply chain management involves the optimization of the way in which a company plans the production of goods or services, procures raw materials from various suppliers, manufactures the goods or services, delivers it to customers and handles returns.
E-Manufacturing starts with an order for a product and then encompasses the entire manufacturing cycle of the product. Manufacturers need a highly responsive supply chain and manufacturing system to ensure that they meet the high expectations of their customers who, in today’s economy, demand absolutely the best service, price, delivery time and product quality.
Manufacturing Execution Systems (MES) provide up-to-the-minute mission-critical information about production activities across the factory and supply chain via communications networks (e.g. Local Area Networks), resulting in the optimisation of activities throughout all aspects of the manufacturing process. MES accomplish this task by guiding, initiating, responding to, and reporting on plant activities in real time, by using current and accurate data. This rapid response to changing conditions, together with a focus on reducing non-profitable activities, lead to more efficient plant operations and processes.
MES reduces cycle times, levels of WIP (Work In Progress), data entry time, paperwork and scrap. It also improves utilization of plant capacity, process control quality, arrangement of plant activities, tracking of orders and customer service.
Implementation of MES invariably results in improved returns on production assets, on-time delivery, faster inventory turnover, larger net profits (through increased cost reduction) and improved cash flow.

Programmable Logic Controllers (PLCs) and SCADA SystemsLiving Online
SCADA has traditionally meant a window into the process of a plant and/or a method of gathering of data from devices in the field. Today the focus is on integrating this process data into the actual business and using it in real time. In addition to this, today’s emphasis is on using open standards, such as communication protocols (e.g. IEC 60870, DNP3 and TCP/IP) and 'off-the-shelf' hardware and software, as well as focusing on keeping the costs down. PLCs continue to gain in popularity. In fact, many SCADA applications use PLCs as the RTU of choice, when communicating with field devices. This comprehensive workshop covers the essentials of SCADA and PLC systems, which are often used in close association with each other.
A selection of case studies are used to illustrate the key concepts with examples of real world working SCADA and PLC systems in the water, electrical and processing industries. This workshop will be an excellent opportunity to network with your peers, as well as to gain significant new information and techniques for your next SCADA/PLC project.
Although the emphasis of the workshop will be on practical industry topics highlighting recent developments, using case studies, the latest application of SCADA, PLC technologies and fundamentals will be covered. The workshop is aimed at those who want to be updated on the latest developments in SCADA and PLC systems and wish to gain a solid appreciation of the fundamentals of their design, installation and troubleshooting.
This workshop is designed to benefit you with practical up-to-date information on the application of PLC and SCADA systems to the automation and process control industries. It is suitable for people who have little or no exposure to PLCs, but expect to become involved in some or all aspects of PLC and SCADA installation. It aims to give practical advice from experts in the field, to assist you to correctly plan, program and install a PLC with a shorter learning curve and more confidence. While the workshop is ideal for electricians, technicians and engineers who are new to PLCs, much of the material covered will be of value to those who already have some basic skills, but need a wider perspective for larger and more challenging tasks ahead.

Practical Distributed Control Systems (DCS) for Engineers and TechniciansLiving Online
This workshop will cover the practical applications of the modern Distributed Control System (DCS). Whilst all control systems are distributed to a certain extent today and there is a definite merging of the concepts of a DCS, Programmable Logic Controller (PLC) and SCADA and despite the rapid growth in the use of PLC’s and SCADA systems, some of the advantages of a DCS can still be said to be Integrity and Engineering time.
Abnormal Situation Management and Intelligent Alarm Management is a very important DCS issue that provides significant advantages over PLC and SCADA systems.
Few DCSs do justice to the process in terms of controlling for superior performance – most of them merely do the basics and leave the rest to the operators. Operators tend to operate within their comfort zone; they don’t drive the process “like Vettel drives his Renault”. If more than one adverse condition developed at the same time and the system is too basic to act protectively, the operator would probably not be able to react adequately and risk a major deviation.
Not only is the process control functionality normally underdeveloped but on-line process and control system performance evaluation is rarely seen and alarm management is often badly done. Operators consequently have little feedback on their own performance and exceptional adverse conditions are often not handled as well as they should be. This workshop gives suggestions on dealing with these issues.
The losses in process performance due to the inadequately developed control functionality and the operator’s utilisation of the system are invisible in the conventional plant and process performance evaluation and reporting system; that is why it is so hard to make the case for eliminating these losses. Accounting for the invisible losses due to inferior control is not a simple matter, technically and managerially; so it is rarely attempted. A few suggestions are given in dealing with this.
Why are DCS generally so underutilised? Often because the vendor minimises the applications software development costs to be sure of winning the job, or because he does not know enough about the process or if it is a green-field situation, enough could not be known at commissioning time but no allowance was made to add the missing functionality during the ramp-up phase. Often the client does not have the technical skills in-house to realise the desired functionality is missing or to adequately specify the desired functionality.
This workshop examines all these issues and gives suggestions in dealing with them and whilst not being by any means exhaustive provides an excellent starting point for you in working with a DCS.

Restful Webserver Based Domotic Home Using Power over Ethernetijsrd.com
This paper presents the way to provide Ethernet internet connectivity and power to microcontroller based embedded systems. This system uses arduino board to store the main application source code, web pages and TCP/IP stack which is a vital element of the system software. An Ethernet controller chip, ENC28J60 is used to handle the Ethernet communications and it is interfaced with the microcontroller using SPI protocol. The site can be viewed on any system with Internet/LAN connection by configuring the specific IP address. There are several I/O pins available at the microcontrollers which are used to interface with lights, fans, curtains, Motors and relays for monitoring and controlling DC appliances. Nowadays, Internet has spread worldwide and most of the internet connections use Ethernet as media for data transfer. In industries or in home appliances, most of the time we need to monitor and control using microcontrollers. Once we enable Ethernet interface to such systems, we can communicate with them remotely over the internet. At the same time power which require to run the device is provided by using power over Ethernet technology which minimize the cable requirement and wastages of copper conductors. The concept of the "Internet of Things" has tied in closely with the popularization of home automation. Ethernet provides inexpensive, relatively high speed network access to individual users and low delay that can support many applications. This implementation is an attempt to connect an embedded device to an Ethernet Using Ethernet based system we can control various home appliances from anywhere across the world.
ETHERNET PACKET PROCESSOR FOR SOC APPLICATIONcscpconf
As the demand for Internet expands significantly in numbers of users, servers, IP addresses,
switches and routers, the IP based network architecture must evolve and change. The design
of domain specific processors that require high performance, low power and high degree of
programmability is the bottleneck in many processor based applications. This paper describes
the design of ethernet packet processor for system-on-chip (SoC) which performs all core
packet processing functions, including segmentation and reassembly, packetization
classification, route and queue management which will speedup switching/routing
performance. Our design has been configured for use with multiple projects ttargeted to a
commercial configurable logic device the system is designed to support 10/100/1000 links with a speed advantage. VHDL has been used to implement and simulated the required functions in FPGA.
Embedded processor system for controllable period-width multichannel pulse wi...TELKOMNIKA JOURNAL
This paper proposes a sophisticated embedded processor system configured on zynq-xc7z020 field programmable gate array (FPGA) device for generating four channels pulse width modulation signals with variable duty cycles and periods using embedded design techniques. The main advantages of the technique are the high ability to perform a simultaneous control on period and pulse width of the generated signals and a high system design adaptation to choose the number of input/output channels. Controlling the the period and the pulse width is achieved by injecting a digital signal to the designed system to manipulate embedded timers’ operation. Vivado design suite is used to develop the system hard ware in the integrated development environment where the processing unit and peripherals are instantiated and interconnected. A practical aplication program in C language is prepared to make the system act according to the target. The designed system can be used to drive multi-phase D.C to D.C convertors. The system performance is verified by using vivado logic analyzer and chipscope windows. The superiority of the proposed approach over other approaches is that it resulted in a multi-inputs/multi-outputs pulse width modulation system with high controllability on the pulse width and the period that ranges from 15 nsec to 60 sec.

application profile that defines commands and attributes
for the following device types:
– Energy Service Portal (ESP) – The ESP is the device that acts as
a gateway into the home and manages the ZigBee Smart Energy
HAN
– In-Premise Display (IPD) – The IPD is a device that presents
energy consumption data and price information to the end user
either by text or graphical means

gas, water, and heat meters
5. ZigBee Smart Energy 101 (cont.)
• Programmable Communicating Thermostat (PCT) – Device used to
control the cooling and heating systems of the home
• Load Control Device – A device such as a pool pump or water heater
that is capable of receiving demand response and load control events
from the utility head end
• Smart Appliance – Like a load control device, a smart appliance
could be a washer, dryer, oven that is capable of receiving demand
response or pricing events from the utility head end
• Range Extender – A range extender has no other purpose than to be
a router device for other devices in the HAN
6. ZigBee Smart Energy 101 (cont.)

9. Anatomy of the Smart Meter Board
• To provide real time metering
updates to the ZigBee module,
the applications processor can
use either UART or SPI
• A device such as a ZigBee
Smart Energy in-home display
(IHD) can query the smart
meter board for metering data
such as instantaneous demand
• This information is delivered to
the in-home display as the
InstantaneousDemand attribute
(defined within the ZigBee
Smart Energy Profile’s simple
metering cluster)
10. Anatomy of the In-Home Display
• IHD reference design based on
the MSP430F4619 and the
CC2530 ZigBee SoC (System-
on-Chip)
• The ZigBee Smart Energy
firmware inside the CC2530 is
queries the smart meter board
for the instantaneous demand
and output the values to the
MSP430 application processor
via UART
• The MSP430 displays the
instantaneous demand value on
the LCD
11. System Block Diagram

• Shows system level interaction between the Smart Meter Board and
the In-Home Display using the ZigBee Smart Energy Profile
• The IHD performs a read attribute request to query for the
instantaneous demand attribute, receives the value in the read
attribute response, then tunnels the data to the MSP430 which
displays it on the LCD
• The protocol used by the host processor to facilitate this transaction is
discussed next
12. Exchanging messages between host processor
and ZigBee module
• The TI Z-Stack provides a transport layer to allow
a host processor to exchange application data
with the application inside the ZigBee module
• This transport layer is called the “Z-stack Monitor
and Test API”, or “MT” for short
• The protocol format discussed here assumes
UART communications, although SPI can be
supported as well with some minor differences to
the protocol format (i.e. SOF and FCS bytes are
not required for SPI mode)
13. Exchanging messages between host processor
and ZigBee module (cont.)
• SOF (Start of Frame): This is a one byte field with value equal to 0xFE
that defines the start of each general serial packet
• MT CMD (Monitor Test Command): This contains 1 byte for the length
of the actual data, 2 bytes for the MT command Id, and the data
ranging from 0-250 bytes
• FCS (Frame Check Sequence): This is a one byte field that is used to
ensure packet integrity. This field is computed as an XOR of all the
bytes in the message starting with LEN field and through the last byte
of data. The receiver XORs all the received data bytes as indicated
above and then XORs the received FCS field. If the sum is not equal
to zero, the received packet is in error
14. Exchanging messages between host processor
and ZigBee module (cont.)
• To tunnel messages into the Z-Stack /****************************************************************
* @fn esp_ProcessAppMsg
application, the host processor uses the *
APP_MSG MT command * @brief Process MT SYS APP MSG to retrieve link key
*
* @param msg - pointer to message
*
* @return none
*/
static void esp_ProcessAppMsg( uint8 *msg )
{
• The host processor application can create switch (msg[6])
{
its own payload format within the case SET_INST_DEMAND: // set attribute data for instantaneous
highlighted “Message” field that has an demand
espInstantaneousDemand = BUILD_UINT24(msg[7], msg[8],
associated “MsgLen” msg[9]);
• In this example, the Z-Stack application break;
case USER_DEFINED_CMD:
sees a ‘SET_INST_DEMAND’ in the first // do something
byte of the “Message” payload to mean }
break;
that this is a set of the local }
InstantaneousDemand attribute
• The MSP430 sends this command every
couple of seconds to update this attribute
in the ZigBee module
• The ZigBee module on the IHD
asynchronously queries for this attribute
over the air using a “read attribute
request”
15. Exchanging messages between host processor
and ZigBee module (cont.)
• The ZigBee module on the IHD shuttles the payload data to the MSP430 for
display using the DEBUG_MSG MT command
• The DEBUG_MSG MT command is a very convenient way to tunnel application
messages received over the ZigBee network back to the host processor
• In this example, the response to the read attribute request containing the
instantaneous demand metering data is sent via UART using the DEBUG_MSG
packet format
• The Z-stack application can call the following API function at any time to tunnel
application payload messages to the host processor:
– MT_BuildAndSendZToolResponse(((uint8)MT_RPC_CMD_AREQ | (uint8)MT_RPC_SYS_DBG),
MT_DEBUG_MSG, METER_DATA_LEN, meterData);
16. Conclusion
• Provided an overview of the ZigBee Smart Energy
application profile and examined use cases in the
HAN
• Discussed the system level interactions between
the smart meter board and in-home display to
provide current consumption data to the user
• Discussed how to use the Z-Stack MT Interface,
which provides an easy way to tunnel messages
to and from a host processor
