:) Yeah... Definitely not a "boring" platform, they are nice to give us work for the upcoming years... :)

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?

Could this be turned into a library? I'd love for a way to have the main program call a function block method using the program's I2C_master device. I assume I should be passing the master as a variable for the function block, but I don't see how that could be achieved

Hi, Is it possible to know of an output of a function block is used? I've found there is a way to find unused inputs of a fb, through the attribute: is_connected. But I'm wondering if the same can be done for an output. Thanks in advance!

Hello, I wrote a function block for a controller but I have a warning code C0373 "expression or part of it has no effect" and the sub routine which contain my function block is underlined in blue. Despite, the FB works perfectly. Do you know why I have this warning ? Thanks. Pascal.

Hallo, ich habe eine Frage zu den init-functions: kann man irgendwie verhindern, dass bei einer Installation der Runtime (normal Update per CODESYS Linux Dialog) die init-functions unter /opt/codesys/scripts/init-functions immer überschrieben werden? Dort habe ich einige CPU/IRQ Anweisungen die ausgeführt werden müssen, aber nach jedem Runtime Update ist die Datei wieder auf Werkseinstellung. Danke!

It's not that you missed something, it's that CODESYS doesn't have this feature. I hope CODESYS can add this feature. We also hope to add function overload functionality.

I am curious if there is a function block or function that will allow me to monitor the J1939 CANBus and pull out all of the SAs that are on a particular bus, without having to have them loaded in the J1939 manager?

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.

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)

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
.
