A system and a method provide an Artificial Intelligence (AI) companion for each Function Block in a Programmable Logic Controller (PLC) program to integrate AI in automation systems. Multiple function blocks and system function blocks are grouped into a logic group. A control problem is broken ...
The next function block I would like to introduce you too is the AND function block. Just like the OR-block this is one of the most fundamental function blocks in PLC programming. It has two inputs and one output. It is very similar to the OR function but works a little different. In...

Bolton Explore book 5.6 Function Blocks The term function block diagram (FBD) is used for PLC programs described in terms of graphical blocks. It is descr...
Motion Control tasks are preferably programmed with PLCopen blocks. Blocks which have been programmed in other SIMOTION languages can be called without problems. User-friendly functions such as "on the fly" variable declarations or automatic syntax checks are available when programming in LAD or FBD...
create a ladder program to determine execution timing because the CP2E CPU Unit can send or receive Modbus RTU commands via a single port. These function blocks send or receive commands sequentially in the order the function blocks are turned ON, which eliminates the need for programming the ...
In addition to the standard FBs like AI, AO, and PID, engineers tasked with developing control strategies can create their Blocks. This is achieved using the Structured Text (ST) language, defined for PLC programming by PLCOpen in the IEC61131-3 standard [4]. As ST is a high-level textu...
@JAPIB: Due to programming conventions I can't declare that variable as an input or input_output (as already stated in the first post). The function blocks that I work with all have standardized input / output / input_output interfaces which cannot / must not be changed. ...
