Post by david24 on Benutzer-Eingabe im Online-Betrieb speichern/Bootapplikation erzeugen ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich habe die Aufgabe ein Kennfeld zu programmieren. Mithilfe des Visualisierungselements Tabelle ist mir dies gelungen (siehe Anhang). In der Inputconfiguration habe ich die Option: Schreiben von Variablen aktiviert, damit der Benutzer die Werte im Kennfeld verändern kann. Beim Testen des Programmes bin ich im (Online-Betrieb, Simulation). Ich verändere die Werte im Kennfeld. Beim Programm-Neustart von CODESYS sind die Veränderungen im Kennfeld nicht mehr da. 1. Kennt jemand einen Ansatz wie ich bspw. den "Datenstand" im Online Betrieb speichern und bei Bedarf öffnen kann oder eine alternative Herangehensweise? "Im Onlinebetrieb speichert CODESYS die Bootapplikation auf dem Zielgerät" 2. Wird dabei eine Bootapplikation vom Code erzeugt welcher im Online-Betrieb sichtbar ist (samt den Veränderungen im Kennfeld) oder wird die Bootapplikation auf Grundlage des Offline-Codes erzeugt? Danke für eure Unterstützung/Ratschläge Gruß David

Post by sanacfu on looking for v2.3 libraries on v3.5.19 ^{CODESYS Forge talk (Post)}
Hi all, I'm new to Codesys and Wago but well versed in Rockwell. I've been tasked with upgrading old Wago 750-880 PLCs that run Codesys v2.3. All I was giving is the original PLC program in v2.3 and the currently running machine. I've spec out to what I believe is a suitable upgrade, the PFC100 2ndGen, 750-8111. As I'm rewriting this code on the Codesys I can't find the same library functions blocks for ethernet settings PLC functions. Currently I'm working on code to get/set the PLC ethernet IP address and HMI IP addresses from the HMI screen. One other function I'm looking for is a warm reset function to the PLC. When googling for this stuff I see a lot of code not in ladder logic. Are these functions now not available to implement in ladder logic? Where can I get more information on finding and implementing this functions? Do I have to buy a license from Codesys to use these functions? The PLC I ordered should be arriving in 2-3 weeks.

Post by struccc on Release SP20 - Changes in behaviour? ^{CODESYS Forge talk (Post)}
This... is not very practical for me - as I have a bunch of different classes - it's just doesn't seems to be very practical to define a NULL for each of them... Something like this I use in parameter definitions. For example: VAR_INPUT refVFD_Drive : REFERENCE TO FB_VFD_Drive := GVL_DUMMY.Dummy_VFD; END_VAR I use this to prepare objects for code I don't control: Typycally visualizations - had many troubles with references set on the fly, right before opening a corresponding visualization... And yes, the instance in GVL_Dummy reports itself as "Fake", so it does not influence the actual application at all. Actually this way I could invalidate a reference, just to set it to a "Dummy" instance.

Wow.... I missed this one in the manual - so there is a special syntax to invalidate a reference... Great :) Seems to work. (it's just mentionned in the examples line)... I've always assigned 0 to the variable, with := 0 - like setting a pointer to 0. In theory, that should work as well. Thanks!

Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi all, I want to know if someone has an idea of how I can write on value change in Modbus Codesys. I have a Wago PLC and I was used to work with E-cockpit which it was quite easy to do that without the necessity to trigger any value when there was a change in the variable ( I will put how easy is ). how you can see just changing the trigger in "On value Change" will do that channel writing automatically when It detects a change in those arrays. On the other hand, in Codesys if I enable the rising edge in Codesys It ask me to put a bool variable and if triggers is going to write that value. That is making me that I have to create a function or a logic to detect the change, the problem I have is that doing that is very tedious. I first approach I got it was to create a Function who returns a bool when the value change, but I tried to keep the old value but what is happening is that in Functions all the data is erased every cycle so I can not keep any Old value. so in the Main program the trigger is going to be TRUE all the time due, the old value is cero every cycle. The second approach I got it was using a function Block (POU_1) and it works but I dont want to instance that function for every Channel or value that I want to check if the value change, Basically if I have 200 values to write trhough modbus I have to create 200 instances of that function which I think it is not practicall at all. It should be a better way to implement this as e-Cockpit from Wago Does. However, I haven't been able to know how.

Post by andrew-budaiev on Properties feature request ^{CODESYS Forge talk (Post)}
Can I leave a feature request here? If it's possible to do now, but I don't know how, please forgive me. It would be good if the following were possible: Ability to copy/paste properties. Ability to tab through properties.
