What is a Data Block? Global Data Blocks in PLC

Data blocks are used to store PLC program data. Global data blocks store data that can be used by all other PLC blocks.

In this article, we will talk about PLC data block instances of different function block types in Siemens Tia Portal and when to use them.

Programming a PLC includes defining and creating a lot of variables. In this article, we will discuss the static and temp variables in PLC.

There are two types of controllers – PLC and motion controller. In this post, we will learn the difference between PLC and motion controller.

Redundancy in industrial automation systems comes in three types – hot, cold, and warm. Learn the difference between Cold and Hot Standby.

The main advantage of using normally-closed contact for stop buttons is to detect the wire breaks in the electrical circuits.

In this post, we will learn the various types of SCADA system architecture such as monolithic, distributed, and networked.

The most commonly used timers in PLC programming are Pulse timers, on-delay timers, retentive on-delay timers, and off-delay timers.

Let’s understand the parameters which help in evaluating the return on investment (ROI) of industrial automation projects.

In this article, we will talk about function blocks in PLC and how to use them in your PLC logic, and how FBs are different from FCs.
