Industry Information 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.
Industry Information Why are the local data and the block parameters for the functions
Table 2 When you call a function (FC), observe the rules below for the parameters of the input and output variables and also for the in/out parameters: All formal parameters must be given
Industry Information How to Create and Use Function Blocks in Siemens TIA
In this example, we create a simple Function Block (FB) using SCL, which includes both input and output parameters. Defining parameters is an
Industry Information 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
Industry Information Siemens FB/FC parameterize the inputs and outputs : r/PLC
We have a few FB''s and/or FC''s we are building up to use over, and over, and over, as well as standardizing our UDT''s for AI/AO/DI/DO. Is there a way we can build the FB/FC such that we can

Industry Information Getting Started With Function Blocks (FB) in TIA Portal
Edge detection inside an FB ensures events are captured reliably, even in auto mode. This same pattern can be extended to multiple conveyors
Industry Information Function inputs in Siemens TIA Portal | PLCtalk
The way a FB works is that input or input/output values are passed to internal variables & used within the FB, in/out are essentially passed in &
Industry Information Passing a BlockDB as a parameter two levels deep
Hi dear Chartier, Declaring Block_DB as a parameter type is only permitted in VAR_INPUT part of a SCL block, or as INPUT in FBD/STL/LAD interface section. But as I have
Industry Information TIA portal
I guess that he is a classically trained computer programmer where you always pass variables to a function and receive an answer back as a Return Value. You are never supposed to

I am working with the TIA Portal Openness API and trying to retrieve interface variables (like Input, Output, InOut) of a specific Function Block (FB). I have successfully accessed the block,
Industry Information Siemens S7 TIA Portal
Both FCs and FBs are useful where a certain sequence of logic needs to be repeated and/or re-used in multiple places, but with different inputs and outputs.

Industry Information Difference between FC and FB in Siemens PLC
In FB, we can leave any of the parameters such as In, Out, In-Out with no address. I hope you like this article about the difference between FC and FB in Siemens
Industry Information Difference between FC and FB in s7?
An FC should never have reason to call an FB. The FC should operate on its input parameters and output the result through its output parameters. As Mr. Chartier has said, there may
Industry Information Passing parameters to blocks
Function Blocks (FB) and Functions (FC) have three different interface types: IN IN/OUT OUT FBs and FCs receive parameters through the IN and IN/OUT interface types. The blocks
