Arduino OPTA PLC - Function Block Diagram (FBD)

The Arduino Opta IoT PLC offers a convenient way to program it using the Arduino PLC IDE in function block diagram (FBD) format. This is a simple and intuitive method, and it is one of the industrial PLC languages. In addition to FBD, you can program the Opta PLC using any of the five official languages specified in the IEC standard and sketches written in C++. The Function Block Diagram (FBD) is a graphical language used to design programmable logic controllers. It allows you to describe the function between input and output variables using a set of elementary blocks. These blocks can be connected to input and output variables using connection lines. When wiring the inputs and outputs of the blocks, you can use single lines to connect two logical points of the diagram. This includes connecting an input variable to an input of a block, connecting an output of a block to an input of another block, or connecting an output of a block to an output variable. The connection lines are oriented, carrying associated data from the left to the right. It's important to note that the left and right ends of the connection line must be the same type. In addition, you can use multiple right connections, also known as divergence, to broadcast information from the left end of the connection line to each of its right ends. However, it's essential to ensure that all ends of the connection are of the same type. Now that we understand the basics of the Function Block Diagram (FBD) let's dive into starting a new project and mapping the physical I/O in the Opta PLC.
