PLC BASED AUTOMATED SYSTEM IN PROCESS INDUSTRY (Final Presentation)
This document describes a thesis project on implementing an automated PLC-based control system in a cement plant. The project involves developing motor block and group control block logic in Siemens Step 7 software to control crushers via a Siemens PLC and Expert Control System SCADA. Methodology includes defining inputs and outputs for motor and group blocks, designing submodules for start/stop, inputs, and outputs, and combining submodules into faceplates. The automated system is intended to reduce labor costs and improve performance by remotely monitoring and controlling plant operations.
Lect01
This document discusses programmable logic controllers (PLCs). It defines a PLC as a user-friendly computer used to monitor and control industrial processes. The history of PLCs is described, noting they evolved from conventional computers in the 1960s-1970s to help automate manufacturing. Key advantages of PLCs include flexibility, ease of making changes, large numbers of contacts, lower cost, and reliability compared to hard-wired control systems.
Plc and scada presentation
This document provides an overview of PLC and SCADA systems. It defines PLC as an industrial computer that monitors inputs, makes decisions based on its program, and controls outputs to automate processes. The history and components of PLCs are described, including the power supply, I/O modules, processor, and programming devices. Programming languages for PLCs include ladder logic, functional block diagrams, and sequential function charts. SCADA is defined as software used for process control that allows users to monitor, control, generate alarms and acquire data from remote facilities. The document discusses the composition, advantages, and applications of SCADA systems.

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
A Visual Guide to 1 Samuel | A Tale of Two Hearts
These slides walk through the story of 1 Samuel. Samuel is the last judge of Israel. The people reject God and want a king. Saul is anointed as the first king, but he is not a good king. David, the shepherd boy is anointed and Saul is envious of him. David shows honor while Saul continues to self destruct.
How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
