Given the response to your API request, I don't think this is a CODESYS issue. The response says ... Please provide a valid API token ... so you must get a valid API key from enever.nl

Hello, the request is no longer relevant. Thank you. Working with the Main Menu bar via the Alt key is the most effective method. It has absolutely everything there. Calling the context menu via the keyboard is not necessary.

Post by kevin123 on auto-answer dialog using system.prompt_answers ^{CODESYS Forge talk (Post)}
I am trying to do "update device" in a project which was saved in a different version of CODESYS using ScriptEngine, a dialog with 'Yes' and 'No' button popped up showing that "Do you want to upgrade the storage format for this project? -if you click 'Yes', storage format will be upgraded... -if you click 'No', storage format will not be changed..." I have to click the 'Yes' button automatically by scriptEngine. I know from others topics here in forum, that some dialogs can be auto-answered using system.prompt_answers. And I also get the messagekey of this dialog: Key: "<< No Key>>" Message: "Do you want to upgrade the storage format for this project? - If you click 'Yes',... i have tried using the system.prompt_answers command below, but the dialog was not auto-answered. system.prompt_answers["<<No Key>>"] = PromptResult.Yes Does someone know how to auto-answer the dialog using system.prompt_answers command with messagekey"<< No key>>"? or any suggestions to solve this issue, Thanks!

Post by egau on Mutate Hash table value ^{CODESYS Forge talk (Post)}
Hi, using the ElementCollections Library, why isn't it possible to mutate a value found within a HashTable? From what I understand, the only way to change a value would be to use the RemoveByKey(), followed by AddKeyValuePair(). My goal is to use a Data Structure that works like a Dictionary in Python. The HashTable seems to come close to this, except that the values themselves seem to be immutable... In python, we can mutate a dict easily (see attached picture).

Post by jvfred on Reading a negative number ^{CODESYS Forge talk (Post)}
I have a Codesys-based Eurotherm E+PLC400 connected to Codesys HMI SL for visualization. I am also bringing in several Pressure Indicators via the Ethernet. Everything works; however, the Pressure indicators sometimes read a negative value. When they do, the displayed value on the screen reads "65532." While I know what it represents, the customer freaks out and wants it to read "0" or a negative number. The value comes in as an integer, just in case that matters. Does anyone have any ideas?

Post by timvh on I want to show the current recipe name in the visualization screen ^{CODESYS Forge talk (Post)}
Maybe the easiest solution for you is to add one STRING variable to your recipe and enter the name of the recipe in variable value. This is little bit double the work (naming the recipe and entering the value of the STRING variable), but in that case you always have the current value of the variable which you can read from the application and show in the visualization.

Post by svn123 on In Simulation Mode, logic is not executing ^{CODESYS Forge talk (Post)}
Please check the attached snapshot. I am converting an int to real and storing in rVlv01_SV and then scaling the value using LIN_TRAFO. In the bottom Status Bar of Codesys, both RUN and SIMULATION are visible. When I enter value 100 as input to INT_TO_REAL instruction and press Ctrl-F7, the value can be seen at the input but the logic seems not to work. I searched for help but could not find anything relevant. What could be the reason. Codesys ver3.5.11 svn

Post by wehling-h on PI Input value ^{CODESYS Forge talk (Post)}
Hi geoweil, have you tried to save changed values to remanent area or using a VAR RETAIN? After restart you have to initialize Counter with last remanent value. Depending on changes per cycle and the possibilitiy of your control unit to write remanent storage. Otherwise you need a buffering system to ensure save backup of last PI_Counter value. May you could read this Thread to get further help: https://forge.codesys.com/forge/talk/Engineering/thread/31e1c8349e/#bf48

Post by syjoo on Recipe Manager in PRG (3.05.13.XX) ^{CODESYS Forge talk (Post)}
I'm using version 3.5.13. Is it possible to handle Recipe Manager in PRG in this environment? Can you give me a simple example? Although it has been confirmed that the functions work on Recipe Manager, they do not work properly when implemented through FB within a simple PRG. I would like to save the current value as a recipe or load the recipe's value as the current value. And I want to save the recipe as a file or load the recipe saved as a file. somebody help me. (TT)

Post by viksym on How to get the motor scaling value from code ^{CODESYS Forge talk (Post)}
If anybody finds this in the future, I managed to do it like this: scalingValue := EncoderPulseCountPerRev / ABS(AxisName.fScaleFactor); No need to use MC_ReadParameter as I am able to read this value directly from the axis object. Using an absolute value of the fScaleFactor is there in case the axis is set as inverted, in which case it would be a negative value. I was not able to figure out how to get EncoderPulseCountPerRev programatically, but since all my servos use an encoder with pulse count per revolution of 16#800000, the final equation looks like this: scalingValue := 16#800000 / ABS(AxisName.fScaleFactor);

Post by alexgooi on Modbus writing on value change ^{CODESYS Forge talk (Post)}
The way I usally tackle this is by syncing only words (then you are able to use the FB above). If you then want to write a Boolean simply type it like this. Value[1].0 := Bool1; Value[1].1 := Bool2; Value[1].2 := Bool3; Uints have the same number of bits than a INT/WORD so these ones will work as well (they are only represented diffrently). A Real will work but you will loose some infomration in the conversion. If you want to keep the information you can convert 2 words to a float with a function (for example with the IEEE-754 standard) . In this way the syncing to the server is very simple and in the Codesys Program you decide what part of the word you want to use.
