Do you know the function of a PLC?

A PLC's functions are divided into three main categories: inputs, outputs and the CPU. PLCs capture data from the plant floor by monitoring inputs that machines and devices are connected to. The input data is then processed by the CPU, which applies logic to the data, based on the input state. The CPU then executes the user-created program logic and outputs data or commands to the machines and devices it is connected to. There are two main types of inputs: data inputs from devices and machines, and data inputs that are human-facilitated. The input data from sensors and machines are sent to the PLC. Inputs can include on/off states for things like mechanical switches, buttons, and encoders. High/low states for things like temperatures, pressure sensors, and liquid-level detectors, or opened/closed states for things like pumps and values.

Do you know how and when to use a wrench (combination, socket, backup, and hex key)?

A ratchet and socket combination (sometimes called a socket wrench) lets you turn a nut or bolt without repositioning the tool on the fastener — like you need to do with a wrench when there isn't enough room to turn it in a full circle. This can make the work quicker. Combination wrenches have a closed loop on one side (box-end) for hexagonal or square nuts, while the other end is an open U-shape (open-end). These wrenches are often used for nuts that are hard to loosen. The closed-end can loosen the nut, while the open end is then used to unscrew it fully.
