That said, using external parameters that are both inputs and outputs ("InOut" parameters in some languages) could make something work with an FC, where those external persistent

Function block (FB)
A function block (FB) is a code block that uses an instance data block for its parameters and static data. FBs have variable memory that is located in a data block (DB), or "instance" DB.
Object Function block
In the PLC project tree, function block POUs have the suffix (FB). The editor of a function block consists of the declaration part and the implementation part. A function block is always called via an instance,
TIA Portal: Functions & Blocks Overview | PDF
It describes local and global operands, with local operands only being valid within the block they are declared in and global operands being valid throughout the entire
TIA Portal: Functions & Blocks Overview | PDF | Parameter (Computer
It describes local and global operands, with local operands only being valid within the block they are declared in and global operands being valid throughout the entire program. It provides an example
Mastering Siemens PLC: The Essential Guide to Function Blocks (FB)
Today, we dive deep into the operational cores of Siemens PLCs, particularly exploring the differences between Function Blocks (FB) and Function Calls (FC). This guide aims to enhance
Passing parameters to blocks
FBs and FCs receive parameters through the IN and IN/OUT interface types. The blocks process the parameters and return values to the caller through the IN/OUT and OUT interface types.
Getting Started With Function Blocks (FB) in TIA Portal
In Part 2 of this series, we explored the use of Functions (FCs) in Siemens S7–1500 programming using TIA Portal. FCs are reusable code blocks without memory, ideal for stateless
Function block (FB)
By designing the FB for generic control tasks, you can reuse the FB
Function block (FB)
By designing the FB for generic control tasks, you can reuse the FB for multiple devices by selecting different instance DBs for different calls of the FB. An FB stores the Input, Output, and
How to Create and Use Function Blocks in Siemens TIA Portal
In this example, we create a simple Function Block (FB) using SCL, which includes both input and output parameters. Defining parameters is an essential part of creating reusable logic blocks.
