Programmable Logic Controller (PLC): PLC is a specialized computer used in industrial segments to control machines and process. PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks. The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC. When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes. The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling programming language. Given: The following motor control specifications must be satisfied by the ladder logic program. Each starter must operate from its own start/stop pushbutton station to wire three starters. A master stop station is included, which will trip out all of the starters when pushed. All pushbuttons must be wired by one set of Normally Open (NO) contacts. An overload on any one of the starters will automatically drop all the starters by programming overload relay contacts.

Develop a PLC-based ladder logic program for automatic packaging system: 1.Draw and explain ladder logic diagram to run a conveyor motor using the following conditions: a.AND Logic Function b.NOR Logic Function Analyze the following conditions: a.Upgrade the ladder diagram such that the motor runs in both clockwise and anti-clockwise direction. b.Use two light indicators to indicate the direction of motor rotation. c.Use a photosensor to detect the package on the conveyor d.Add start stop logic (Use both AND logic and OR logic, where necessary use switches to control the direction)

Design Questions Requirement 1) Implement a timer with the use of a binary up counter driven by a 1 Hz clock. The timer is activated for a duration of 10 seconds. After 10 seconds has elapsed, it should provide an output signal to the vehicle counter to request it to stop the vehicle counting process. Show the timing diagram in order to verify that it is counting up correctly.

A PLC is used to control a single-axis robot, in which the axis is driven by a pneumatic cylinder. An output signal to the pneumatic cylinder causes it to extend (ON state). When there is no signal, the pneumatic cylinder retracts (OFF state). The gripper is an also driven by a pneumatic cylinder. The gripper open position is an OFF state and the closed position is an ON state. In order to perform a task, the following sequence of operations must be performed: TH Sequence No. Аxis Gripper OFF OFF 1 ON OFF ON ON 3 OFF ON 4 OFF OFF The process begins when the start bush button is ON and a part triggers a limit switch. For safety, an emergency switch is used to shut off the entire system. Design a PLC ladder diagram for this application.
