Hi, Our program incorporates various function blocks and programs written in different languages such as St and SFC. They implement numerous actions and methods using different languages from their function blocks. My question is whether the execution order of function blocks is associated with the programming languages used. I understand that cycle time can be configured in the task configuration, but I'm curious if there is a specific sequence order of execution for function blocks written in different languages. For example, all function blocks in (ST) are executed first, followed by the execution of (SFC). Specifically, when the function is written in (ST) and the action is implemented in (SFC). I modified all function blocks in the main PLC program and configured a task configuration for the main program.

Ist es unter dem FUP-Editor von CODESYS V3.5 SP18 möglich, eine Leitungsverzweigung mit einem existierenden Block (z.B. AND-Glied) zu verbinden? Oder den Ausgang eines existierenden Blocks mit dem Eingang eines existierenden Blocks (z.B. OR-Block) zu verbinden? Gibt es dazu Vorschläge?

Hi, will check the CodeSys function blocks. Didn't know those and usually the OSCAT lib is a bit more advanced. Kind regards!!

All your ACT values in the PID blocks are are not valid with a NaN.

I use the ifm products which have these blocks in their package. I would think Wago has something similar.

Function blocks in a SFC are executed left to right, top to bottom, instructions in ST are executed from left to right top to bottom as well. I think you are asking about the execution of POUs although you use the name function block, I believe POUs are executed in the order they are shown under the main task.

What maybe helps is the Visu Dialog ST demo project: https://store.codesys.com/en/visu-dialog-st.html This has an application IECOpenDialog where dialogs are opened using the VU.FbOpenDialogExtended function blocks. The fbOpenConfigurationDialog call has a reference (interface) to the "close listener" FB of which it's method is automatically called when the dialog is closed. This way you can create specific function blocks for each dialog when it is closed and do what you want with the data that might have been changed.

I have two ethernet Ip drives and created Function Blocks for different motions tasks. I am using same FB for both the drives. When I try to execute the relative move start command on FB for both the drives it is not working. However, if I add 1ms second delay between the execution of each drive it is working. Also when I change the rung order it is working for the first drive in the rung. what could be the wrong here?

Thanks for the answer. So yes I've enabled expert settings, and yes i've added some SDOs, but some of them who are generated are likely making a mess in the network and generated error with my device... From which library comes those 2 function blocks ?

I'm not sure I understand what you're asking, but I don't believe a function block with this behavior exists in the default libraries. I think the best solution would be using multiple and/or blocks or make your own function block.

Can you post the new code that you have by chance? Also, are you able to send the values of tags dynamically with the RTAC in this JSON format? I'm running into a lot of road blocks with it.

You can use the R_TRIG and F_TRIG function blocks to generate a pulse in Rising or Falling edge of your signal. Have a look here: https://content.helpme-codesys.com/en/libs/Standard/Current/Trigger/R_TRIG.html

Is there any solution for this ? or do you need to use wago runtime and use the function blocks for the CanOpen ?

Thanks for your response and your idea. To sum up, you also have no idea how to connect two existing blocks. Meanwhile I worked with "PLCnext engineer" and the result is:

Hi everyone, so a little update to this, I've come back to this project in the new year, and got it working. Yeah!, However, now with the new licensing setup, I need a new SoftMotion license, but it doesn't seem to be compatible with the previous Raspberry Pi SL license. Has anyone had any luck with Raspberry Pi and SoftMotion_Lite? Specifically the licensing of such? My customers new installation needs to be rebooted every 30min which is causing headaches! Another option is to not use the SoftMotion function blocks, and control the EtherCat amplifier directly, but I'm not sure how to do so. Does anyone have a specific example project of how to control a servo without the use of the SoftMotion function blocks? Thanks everyone for any assistance rendered. It's very much appreciated! Toby

Hello all, I am extremely new to Codesys and to programming with these languages in general. I have an HMI panel with 8 physical buttons to the right side of it. I am trying to have these set to change the visualization to a specific screen which I have designed 8 of. I currently have "use CurrentVisu" enabled in the visualization manager. I also have input blocks with all of the buttons being directed to output blocks which I want to have as the switcher for the visualization. Picture is attached for what I have currently. This could be the wrong approach to this issue. Any help is much appreciated.

Hi Jack, I think you have to look at a FB in a different way. A Function block (Class) can contain its own data. In other words don't define loose data in your GVL, but define a instance of a FB (Object) in your GVL: Example: Function_Block Basic_Class VAR_INPUT Open_Command: BOOL; END_VAR VAR_OUTPUT Opened: BOOL; END_VAR if Open_Command then Opened := TRUE; ELSE Opened := FALSE; END_IF Global Variables Objects: ARRAY[1..100] OF Basic_Class; //Here you ar defining you objects END_VAR In your code you can directly acces the data and couple it to the IO: GVL.Objects[1].Open_Command := %IX0.0; %QX0.0 := GVL.Objects[1].Opened; //To call the code itself use: GVL.Objects[1](); If you want to take this a step further you are also able to add methods and properties to the FB/Class end thereby creating a OOIP program

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
or OR
.
