Programmable Logic Controllers - Assignment Example The RES instruction is used to cancel the SET instruction, hence putting the PLC off. In the contemporary society, electronic devices are used in variety of ways. Electronic devices which make use of microprocessors rely on signals to understand information. Signals are available in two forms, i.e. Digital and analogue. Electronic devices can only understand information that is in digital format, and hence the analogue signals are meaningless in such devices. For this reason, the conversion of analogue to digital signals is essential, especially considering that most real life situations lead to the production of analogue signals. The analogue to digital conversion of information, changes the format of the information, without altering its content. Microprocessors are used for the conversion of the analogue signal to digital. The principle used in the conversion of analogue signals to digital signals by the microprocessor is the voltage variation. The microprocessor used sensors, which detect the incoming analogue signals, and translate them into voltage levels. For instance, the translation of temperature of 0 – 1000c, leads to the assignment of 0 volts to 00c, and 5volts to 1000c. Any value that is above 0volts represents an HIGH, and hence microprocessor can show the actual value, depending upon the number of levels the microprocessor can represent. The resolution of the A/D converter refers to the number of intervals which can be divided from a certain analog input range. Since the interpretation of the analogue input (e.g. temperature) requires assigning of voltage levels, the number of levels which can be represented is determined by the resolution. Resolution of A/D converter is represented in bits, for instance, an n-bit A/D converter has a resolution of 1/2n. The word length, as used in the microprocessors refers to the

Introduction to Business........VIII - Essay Example Leadership qualities are not possessed by every manager. The manager must have a charismatic personality and the influential power to become a good leader. 3. Human skills are identified as the ability of an individual to work effectively and in harmony with other people. A person who has good human skills can interact and cooperate more effectively with others and can use it as a valuable asset in team work. An individual possessing human skills, has good etiquette, can handle difficult people, and can negotiate well with others to convince them on his or her terms. e. Self-actualizing Needs – this is the highest level that a person can reach. On this level, he or she is not concerned about others’ opinions and is more interested in experiencing his or her full potential Theory Y, on the other hand, assumes that an average person seeks responsibility and wants to work. He or she can be motivated and committed to their work if they see rewards such as self-fulfillment. Therefore under this theory, the motivator for an individual is his or her need of self-fulfillment and this can be used to create harmony between the personal and organizational goals. 6. Operational planning comes under the strategic work plan. It describes how the business is to accomplish the milestones and objectives. This is done through putting a portion of the strategic plan into action which is to be completed within the duration of the operational period. Generally, this period is equal to a fiscal year. 8. Strategic Planning is done on the senior management level of the organization. It defines the overall strategy of the business. The strategic plan gives the business a direction and states how that plan is going to be achieved. It also includes planning of resources, such as capital and human resource. 9. Generation Y include those people who are born in the period from mid 1970s to the early 2000s.
