05704-A-0144 When it comes to learning the foundations of PLC programming, it can be as easy as flicking on and off a switch. That’s the main difference between discrete and analog I/O modules! Discrete signals are simply on or off, whereas analog signals vary. 

05704-A-0144 are responsible for collecting data from input signals and sending the information through output signals to control devices in order to perform specific functions. Depending on the application or device, a PLC programmer must determine whether to use discrete or analog I/O. 

05701-A-0502When learning the fundamentals of PLC programming, it’s necessary to have a basic understanding of inputs and outputs, and the key differences between discrete and analog I/O modules. Keep reading to gain a deeper understanding of these two mechanisms. 

If you’re brand new to 05701-A-0502 training, I/O is a widely used term amongst technicians which stands for “Input/Output.” I/O is the communication between an information processing system and the outside world. Inputs are the signals, or data, received by the system and outputs are the signals sent from it.

05701-A-0502 of the simplest ways to think of I/O is by using your computer as an example. Your computer is an information processing system, and the user is “the outside world.” Computer inputs would be the keyboard and mouse which receive commands from the user, whereas the outputs would be the monitor and printer. When you think of it in terms of a PLC, you should note that PLC’s are composed of two basic sections: the Central Processing Unit (CPU) and the I/O interface system. The I/O is what connects the information processing system (the CPU) to the outside world, like the machines and Human Machine Interface (HMI). Input modules detect the status of input signals, such as push buttons, switches and sensors. The output modules control devices such as motors, relays, and lights.
