Hi We have picked up an issue OSCAT_BASIC.Scale_r function call not working in the old lad and FBD version 4.60. Gives no output on the function call. When we convert this to LAD2 it works. As can be see by the two screenshot in normal LD not working in LAD2 it works. Please confirm if this is an issue with Oscat or with LAD in 3.5.21sp3, is there an workaround. Regards Shaun

here is formula for scale function you can impliment your own scale function Output=OutMin+(Input−InMin)×(InMax−InMin)(OutMax−OutMin) FUNCTION_BLOCK FB_Scale VAR_INPUT xIn : REAL; // Input value (e.g., raw sensor) xInMin : REAL; // Input range minimum xInMax : REAL; // Input range maximum xOutMin : REAL; // Output range minimum xOutMax : REAL; // Output range maximum END_VAR VAR_OUTPUT xOut : REAL; // Scaled output END_VAR VAR xGain : REAL; xOffset : REAL; END_VAR // Implementation xGain := (xOutMax - xOutMin) / (xInMax - xInMin); xOffset := xOutMin - xGain * xInMin; xOut := xGain * xIn + xOffset;

Unfortunately, The same behaviour still exist with SoftMotion V4.19.0.0 too. (default ramp type is quadratic instead trapezoid for new created axis object) For your information.

Post by matthew on New Ladder Editor Issues
CODESYS Forge
talk
(Post)
Hi There, When using the new ladder editor there is no option for function blocks to Remove uncalled FB call parameters. I also see no update function block. When you double click the function block it no longer opens the function block. I also now get warnings if I insert FB call without a contact in front. Warning is: (Impl)): C0373: Expression or part of it has no effect I take it the new editor must work differently? The only reason for using new ladder editor is the ST execute/block editing is far better, If you have alot of text in the old ST execute the editor window is very small and when online it's even worse. The new ST block seems a lot better Thanks!

I think what you want is a declaration period function for the page, but unfortunately CODESYS does not have it.

Hello, I program a function for an Ethernet/IP controller. I made a structure with input and output corresponding with the map of my controller for the function block. My problem is that I don't know how to do the link between the controller and my PLC (CC 100 from Wago). The addresses declare in Codesys are illogic, The first addresses are 12 and 13 then 7 then 4. How to do corresponding the addresses of the controller and the input / output structure ? IP adress ? Does I must create the all variables of controller with the controller adresses to use with the function block ? Thanks for your help. (I hope I'm clear, I'm not english)

Hi, these variables are internal members of the axis. They measure the duration of some internal function calls.

Post by eguerra on Error in ScriptingEngine Docs - create_pou()

In the ScriptingEngine documentation there seems to be an error (or missing information) in the ScriptIecLanguageObjectContainer part ( https://content.helpme-codesys.com/en/ScriptingEngine/ScriptIecLanguageObjectContainer.html#ScriptIecLanguageObjectContainer.ScriptIecLanguageObjectContainer ). The description of the function create_pou() doesn't specify the correct arguments requested, it only says create_pou(type: SpecialPouType) and a script using the documentation definition of the function will raise an error. I tried passing the function arguments similar to the ones specified for the create_dut() function and it seems to work fine: create_pou(name, PouType) , name : str UPDATE: The offline help has the correct definition IExtendedObject<IScriptObject> create_pou( string name, PouType type = PouType.FunctionBlock, Nullable<Guid> language = null, string return_type = null, string base_type = null, string interfaces = null )

Hi, you can call the decoder function block in a loop and/or decrease the task cycle interval of Task_PATH.

You can simply excute the function block SMC3_ReinitDrive to the referred axis.

Hello, Thank you for your answer. I'm afraid I was not clear on what I was trying to achieve. I'm trying to change parameters and command axes from inside a function block and the first thing that came to my mind was pass both the EtherCAT slave and axis to the function block (as image attached). But, I believe it's worse than just pass directly the EtherCAT slave address to the function block (is it???). However I was wondering if there was a way to get the EtherCAT address directly from the axis, so I don't need to pass the EtherCAT slave nor the EtherCAT address to the function block. Thank you again!

Post by anlebr on Alarm group template - Is it not possible with several instances?
CODESYS Forge
talk
(Post)
Hi In the POU section of my project I have created a Fan function block and defined an alarm group template for this FB with one alarm (Motor fault). In the PLC program I define two instances of the fan function block. When going to the alarm configuration and pressing "Create or update alarm instances", I get two alarms listed. So far so good. However, when I start my program and check the alarm table in the visualization I only see one alarm, even if both are active. Am I doing something wrong, or is it not possible to define alarms on a function block level and get one set of alarms per instance of the function block?
