The Logic Diagram

The schematic shows how electrical components and panels work together. They double-check drawings for manufacturability. A logic flow diagram is an example of a schematic that a programming program must be able to create and interpret.

Before installation, programmers test the new program with automation equipment to make sure it is safe. They are responsible for testing programs and equipment. When the program is ready to be integrated with equipment, the programmers are there to make sure it goes smoothly.

They provide guidance and support to technicians during the installation process, and then train them in safe and efficient operation of the program. The programmers of the company provide technical support to users both verbal and in writing. They can fix any problems if they arise.

The Function Block of a PLC

Dick Morley invented the first of the PLCs. Since then, the industrial and manufacturing sectors have been changed by the use of the PLC. There are a lot of functions in the PLC, like timing, counting, calculating, comparing, and processing.

The most important module in a system is the rack or the Chassis. There are different shapes and sizes of the PLC. Larger PLC racks are required when more complex control systems are involved.

The module has a central processor. The operating system, drivers, and application programs are included in the ROM memory. The memory is used to store data.

The processor is the brain of the machine. It is a microprocessor-based CPU and it does not use timers, relays or counters. Two types of processors can be used with a PLC.

A one bit processor is used. Word processors are used for processing data. The command is sent to controlling devices after the input data from the sensors is processed.

The Course "The Art of Learning"

It is brilliant to program from scratch. I am 45% through the course. Paul is a great teacher.

InTouch: An Operator-Based System Control Tool for a Pump

It is important to run the plant without failure. It is important to have redundant systems so that if one fails the redundant system can take care of the plant. The operator will have access to historical and real-time trends, alarms and reports.

The operator can give commands to control hardware for opening the valve, changing the set point, starting the pump, and so on. Normal system status messages can be represented by events. An event is triggered when an operator logs into InTouch.
