Have you tried using the persistence manager which uses the file system of the controller to store persistent variables?

Post by imdatatas on TO_STRING operator not working for IMPLICIT ENUM CODESYS Forge talk (Post)
Hi Everyone, It is a very useful feature to be able to obtain the enum value as a string with the TO_STRING operator by defining {attribute 'to_string'}. However, unfortunately the same function does not work for IMPLICIT ENUMs. I hope that {attribute 'to_string'} behavior can also work for Implicit Enumeration data types in one of the upcoming Codesys versions. https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_to_string.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_datatype_implicit_enumeration.html Best regards, Imdat

Post by sturmghost on Initialization of visualization variables and cyclic code execution CODESYS Forge talk (Post)
I'm looking for a smart and short way to implement initialization of visualization variables depending on the visualization input. For an easy example consider a rectangle which rests at XPos := 0 when the input state is false and at XPos := 50 when the input state is true. My visualization variables look like this: VAR_IN_OUT State : BOOL; END_VAR VAR XPos : INT; END_VAR I put this rectangle via a visualization frame element into another visualization and link a frame reference variable with the state to it. If the variable is true, the rectangle should rest at XPos := 50 and false at XPos := 0 at visualization init but how should I assign the 50 or 0 to the internal visualization variable XPos? I would need some init-methode for the visualization but I dont want a global init-method for such tasks. I want to do it inside of the visualization element but I can't see any solution for this? It would be good to be able to define ST-code within the visualization element which runs cyclic at each VISU_TASK task-cycle then I could just check the input state and change the XPos accordingly. Does someone have a solution?

Post by phoward131 on Text List Fallback Value CODESYS Forge talk (Post)
I am relatively new to Codesys and I'm trying to develop an HMI that displays what mode a particular device is in based on an integer value. I am currently using dynamic texts with a text list which works fine but I am looking for a way to display a particular string (ie 'Unknown') when the index doesn't match any of of the indices in the text list. I can enter 'Unknown' in the text property of the text field element which works as expected but it displays the single quotes on the visualization. How can I escape these quotes to simply display the word Unknown? Thanks!

Post by programmierer on Implementing UDP Communication CODESYS Forge talk (Post)
Hello everyone, I hope you can help me with my problem. I am new to programming and am currently working with a WAGO controller in our lab, which controls a heat pump. My goal is to send the electrical power of the heat pump (Pel_WP) via a UDP connection to a specific IP address. I am using Codesys version 2.3 and following the guide I found here: https://forge.codesys.com/forum/de/396/genmed-Konfiguration%20der%20UDP%20Kommunikation%20Cosesys%20S7.pdf. I have adapted the guide to suit my needs. The data sending works since I can force the reception value Pel_WP and the data is sent accordingly. However, I am having trouble with the receiving part. The reception value is not being correctly received, and the diSocket variable shows -1. The connection between the heat pump and the WAGO controller seems to be set up correctly, as the heat pump is listed under the communication parameters with the correct IP address. I have also attached images to provide a better view of the setup. I would greatly appreciate any support or suggestions for a solution. Thank you in advance!
