Distributed Control System (DCS) Applications, Selection & TroubleshootingpetroEDGE
Since the first Distributed Control System was installed in the late 1970’s, the concept of DCS has swept alternative control technologies from the field. The substantial growth, in the construction of plants in the traditional heavy process industries, such as power generation, refining, oil and gas, water and petrochemicals, is driving significant growth in the utilization of DCS. The broad architecture of a solution involves either a direct connection to physical equipment, such as switches, pumps and valves or connection via a fieldbus communication system.
The document discusses the evolution of process control systems from early pneumatic and analog electronic implementations to modern digital implementations using distributed control systems (DCS). It describes the key components and advantages of DCS, including flexibility, reliability, and the ability to implement advanced digital control strategies. DCS networks allow different control modes and distributed control for large, complex processes.
The document discusses the Distributed Control System (DCS) at IFFCO Phulpur, located near Prayagraj, India. The IFFCO Phulpur facility produces ammonia and urea and has a production capacity of 0.824 MTPA for ammonia and 1.416 MTPA for urea, as well as other fertilizers. A DCS is a specially designed control system used to control large, complex industrial processes through distributed controllers connected by communication networks. The key components of a DCS include field devices, input/output modules, controllers located near field devices, a human-machine interface, and control engineering workstations.

The computer would store data histories and use SCADA software to allow remote monitoring. The system architecture includes sensors, intelligent electronic devices for data collection, and a central computer running analysis software to evaluate breaker condition and guide maintenance. The online monitoring allows reliable supervision of circuit breakers to improve power system reliability.
5 Techniques to Achieve Functional Safety for Embedded SystemsAngela Hauber
Failures of safety-critical electronic systems can result in loss of life, substantial financial damage or severe harm to the environment.
Safe computer systems are typically used in avionics or railway applications requiring particularly high reliability. This also goes for the medical market, while industrial automation environments demand more and more functional safety as technology becomes readily available.
1. SCADA systems are used to monitor and control industrial processes through remote terminal units (RTUs) and programmable logic controllers (PLCs) that connect to sensors in the field. They allow for centralized supervision and control of geographically dispersed processes.
2. A key component is the human-machine interface (HMI) which presents data to operators and allows them to control the process. Other components include RTUs/PLCs that connect to field devices, a communication system to connect components, and a supervisory computer system for data collection and control.
3. Security is a major concern as SCADA systems often have vulnerabilities like hardcoded passwords and lack of authentication. Successful cyber attacks could disrupt
5 Application Examples Using Wireless Communication in Harsh IoT EnvironmentsMEN Mikro Elektronik GmbH
The document discusses 5 examples of wireless communication applications in harsh Internet of Things (IoT) environments. The examples include: 1) A SCADA system that records and processes vehicle data and sends it via UMTS to headquarters. 2) A WLAN server that provides passenger internet and information on company buses. 3) An infotainment system that streams media to displays and mobile devices on long-distance coaches via WLAN. 4) A system that provides passenger comfort functions, diagnostic data recording and analysis, and information via a wireless portal on trains. 5) An oilfield server platform and router that relays drilling data in real-time to an operator center via GSM from remote drilling sites.
DCS is a distributed control system used to control large, complex industrial plants. It consists of three main stations - the engineering station which configures the system, the operator station which monitors the system, and automation stations which connect to field elements and control processes. DCS systems distribute control elements throughout a plant rather than centralizing them. This allows for greater flexibility and reliability. Common DCS systems include Siemens' Simatic PCS7, which uses programming languages like CFC and SFC and integrates process control capabilities. DCS is primarily used in large industries like chemical plants, oil refineries, and power grids.

[White paper] detecting problems in industrial networks though continuous mon...TI Safe
Automation networks offer a range of real-time applications and data, making necessary the continuous monitoring of the quality of services. The parameters of QoS (Quality of Service) seek to address priorities, bandwidth allocation and network latency control. There are several QoS parameters to characterize a computer network, and that can be used for monitoring purposes.
Each SCADA network, in a healthy state, presents a specific QoS which rarely changes given the repetitive process of the IACS operations. The continuous monitoring of QoS parameters of an automation network may anticipate problems such as malware contamination and equipment failures like switches and routers. It is very important to be aware of these changes in behavior in order to receive alerts and promptly handle them, avoiding incidents that could compromise the operation of the network and be financially or environmentally costly.
In addition to the monitoring of network traffic, it is also necessary to monitor resource consumption of critical servers, such as the processing (CPU), memory, storage capacity and hard disk failures, among others.
This work aims to establish a method by which SCADA security professionals can differentiate and qualify any problems that may be occurring through continuous monitoring of the automation network performance parameters giving a more behavioral approach than current signature-based ones.
We presented a series of tests conducted in our laboratories in order to measure the performance of a simulated automation network parameters using a small SCADA network sandbox. First we measured the normal operating parameters of the network and reap its main graphics obtained with the proper tools. In a second step we practiced several attacks against the simulated automation network. During all attacks we collected the operating parameters of the network and its main graphics.
At the conclusion of the work we compared the graphs of the network in healthy state with the graphs of the network with the security incidents described above. We detailed how the network parameters were affected by each kind of incident and built a table showing the way the main parameters of an automation network were affected by the attacks
Supervisory Contro and Data Acquisition - SCADAAhmed Elsayed
This document provides an overview of SCADA (Supervisory Control and Data Acquisition) systems.

Exploring Deep Learning Models for Image Recognition: A Comparative Reviewsipij
Image recognition, which comes under Artificial Intelligence (AI) is a critical aspect of computer vision,
enabling computers or other computing devices to identify and categorize objects within images. Among
numerous fields of life, food processing is an important area, in which image processing plays a vital role,
both for producers and consumers. This study focuses on the binary classification of strawberries, where
images are sorted into one of two categories. We Utilized a dataset of strawberry images for this study; we
aim to determine the effectiveness of different models in identifying whether an image contains
strawberries. This research has practical applications in fields such as agriculture and quality control. We
compared various popular deep learning models, including MobileNetV2, Convolutional Neural Networks
(CNN), and DenseNet121, for binary classification of strawberry images. The accuracy achieved by
MobileNetV2 is 96.7%, CNN is 99.8%, and DenseNet121 is 93.6%. Through rigorous testing and analysis,
our results demonstrate that CNN outperforms the other models in this task. In the future, the deep
learning models can be evaluated on a richer and larger number of images (datasets) for better/improved
results.

Conditionally checking before execution
In order to facilitate the execution of Device Control Sequences,
instructions shall be provided to Operators so that the adequate
sequence of steps could be reviewed, prior to performing a con-
trol action.
(10) Alarm Processing
Monitoring of alarms is important in substation operation, espe-
cially during significant events such as total or partial system out-
ages. An event is defined upon any change during operation and a
group of events would initiate an alarm. Any unsolicited status
change or violation of any allowable limits of the power system
variables shall initiate an alarm as well.
(11) Event with Alarms
Events with alarms are:
Any unexpected status change of an entry
Any control point change request or indication that does not
result in a change of the associated input (status) within a
determined period of time.
Any analog input that violates one of the alarm limits defined
by the Operator
An RTU does not answer correctly to a predefined number of
interrogations
The operating status of any substation equipment has
changed without having been previously scheduled and/or
requested by the Operator.

Trending tracking is included in the DAC Subsystem. It shall be
possible to represent trends both from historical data, using the
information stored in the HIS, and with real-time data. Refer to
Figure 7.
(13) Tagging
Tagging of the circuit breakers and disconnector switches for
maintenance, hot line work or automatic re-closing is an im-
portant part of the @Station® design criteria. This will be accom-
plished by using a latch in the redundant Relay & BCU. Once set,
the latch provides an indication to all remote systems (TCC), sta-
tion computers and on the local Relay& BCU display indicating
the breaker was tagged out.
Four colored tags (Red, Yellow, Orange, and Blue) are used in
@Station®. The Red Tag applied on the Circuit Breaker (CB) or
Disconnector Switch (DS) is used for blocking their operation.
Yellow Tags are used for hot line work that a Yellow Tag applied to
a breaker will block its the re-closing function. Once the Yellow
Tag has been applied, the re-closing cannot be put back into ser-
vice until the Yellow Tag is removed. Orange Tags are used for
sectionalized lines that are used for indication only. Blue Tags are
used on the Console display only and that is for the operator to
provide informational comments. The Tagging function also allows
the user to enter the following tag information:
Job/Permit Number

Purpose
“Tagged by” and “Tagged for” Information

Predict remaining life of transformer through calculation of
cumulative aging of isolator
With off-line calculation results, user can determine the decre-
ment of insulating life of transformer, thus predicting the remain-
ing operational time of the devices. Off-line calculation result may
be used for planning on repair or replacement of power trans-
former on load diagrams and available environment mode (Figure
15).
Predict allowable overload time for different operation cases
with simulation functions
This function can calculate with assumed data. Operators can
switch to manual mode to run calculation simulation for define
timeframes. For example, simulation function can be used to
determined allowable overload time of transformers (or transmis-
sion lines) if a machine fails when two transformers are operating
in parallel. Refer to Figure 16.

The program allows for extracting calculation results in Excel for-
mat for reporting and storing.
