Standard Blocks

When you double-click on the motor FB from the LBP, what happens?  Are you not able to see the internal logic and FB interface?

Hello,

I was just looking for standard blocks or at least a general guide of how to construct the most basic blocks (valves, simple motor, etc...) with things to take account of. 

So I found this  Library of Basic Processes (LBP) V2.7 for TIA Portal V17 and it seems very well programmed. But when I look at the simple motor,for example, I can't figure out where to "wire" a PTC signal for error, an inductive sensor for rotation control to turn off the motor again if the shaft is not spinning, limit switches, etc. 

...

Not asking precisely for the solution for this particular case but I'd like to be capable of modifying the block to adapt it to my specific requirements, but I'm unable to find a Siemens or a another guide online that can clear my doubts. 

...

Regards.

In the block interface of the block you can now see in the internals of is a good place to put your needed I/O.

Then you can remove any unnecessary block interface inputs and outputs (for your basic motor block) - just use Find (search) within the SCL logic for all those tags you end up removing and remove all associated code that puts those tags on the left side of := plus any usage within other SCL code/logic.

And of course, edit the title data to note changes you make, being sure to retain Siemens credit for programming the original block.

Hello 0_Einstein.

In fact, I'm able to see the internal logic of the motor block.

The thing is that if I want to "build" myself a motor logic where do I look for tips and a guide? I don't mean the use of the TIA Portal interface or internal functions but a good practices guide for motor and valves for example.

The libraries that Siemens publish in recent times is built around some programming and style guides. You can find these here: [LINK: Programming Guidelines and Programming Styleguide for SIMATIC S7-1200 and S7-1500 and WinCC (TIA Portal)] 

There is also the concept of standardization that plays a role. [LINK: Guide to Standardization]

These links are not specifically helpful on how to build a control block for valves / motors. But honestly it is not possible to tell you what should be contained. As you demonstrated yourself, the blocks provided by Siemens already does not have what you need. Be careful to try and build a block that is a cure-all.

The first generation of blocks would be far from handling every scenario. Later generation may be closer but you may still have various versions.

Do these thoughts help you move forward? If not - where are the doubts?
