Post by pistola on Case Function - Multiple Conditions, Is it possible? ^{CODESYS Forge talk (Post)}
Looking at the help (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_st_instruction_case.html). I don't think it is possible but I figured I'd ask. I'm looking at have a case that evaluates two variables, instead of having multiple If Else statements I was hoping I could just use a case. Example * Case Var1 & Var 2 of 10 & 10: Instruction Code 10 & 20: Instruction Code 20 & 20: Instruction Code End_Case Obviously I tried typing as noted above and Codesys threw an error. But I was wondering if there was a different way of programming to make something like this work? If not I'll just use a bunch of If Else Statements, Thanks.

Post by hjohnson123 on Automatically selecting a visualization element ^{CODESYS Forge talk (Post)}
I'm looking to automatically select a text field element in my visualization. I'm not sure if this is possible, as I don't know how to get the data on specific elements. I am wanting automatic selection of the text field, as I am using a keyboard-input barcode scanner, which should always input the barcode into the text field whenever a barcode is scanned. Does anyone know if this can be done?

Have you looked at this? https://forge.codesys.com/prj/codesys-example/element-collect/home/Home/ It's not exactly what you're looking for, but I've been able to make some things work more efficiently using this library.

Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Finnaly i get it working. There was a line in the file that set the ADS1015 chip in /boot/firmware/config.txt which i removed and after that the ADS1115 has a green turning circle and i got values. i created a new component so it fits our ADS1015. see screenshot. It works also with Codesys Control for Raspberry Pi 64 SL after adding the ULINT_TO_UDINT conversion in the library. i think the chip was all the time in use by the Raspberry pi itself. Thanks for your help!

Post by full0pullpolen on Device User Logon ^{CODESYS Forge talk (Post)}
The following guide describes how you can adapt the user management for the first time in a project. It deals with the definition of a user and a group to which he belongs. Requirement: the project for which the user management is to be set up is opened. There is no adapted user configuration yet. Select Project Settings ‣ Users and Groups and then the Users tab. The user Owner is already created by default. Click on Add. ⇒ The dialog box Add User appears. Enter a login name, for example ‘Dev1’, and a password. Leave the option Activated activated. Click on OK. ⇒ On creating a group for the first time, CODESYS now requests you to authenticate yourself to perform this action. In this case, enter ‘Owner’ as the current user. Do not enter a password, just click on OK. The user Dev1 appears in the list and is automatically a member of the group 'Everyone'. Change to the tab Groups, in order to add the user to a new group. ⇒ The groups Everyone and Owner have already been created. Click on Add in order to open the dialog box Add Group. Specify at least one name for the new group, for example ‘Developers’. Activate the checkbox next to the entry User ‘Dev1’ in the field Members. Click on OK. ⇒ The group Developers now appears with has user member 'Dev1'. Switch to the Users tab. ⇒ The user Dev1 now appears as a member of the groups ‘Everyone’ and ‘Developers’.

Post by carohe on %t SystemTime in Variable ^{CODESYS Forge talk (Post)}
Hello, if you enter %t as a "Text" on a rectangle and do not link a variable in "Text variable", it automatically displays the system time. My question is, where do if find a variable, that contains exactly this time? I tried numerous variants using GetLocalDateTime or GetSysTime but I always have to manage timezones myself (which I do not want to do). I only want a variable with the date an time from my windows system, where the visualization is running. Where can I find this variable?

Post by garrian on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
Thanks for your reply. I belive it is contiguous, I'm writing to adress 0 to 4. Or, do you mean something else? Well, something is happening. If I on the client set adress 1,2,3 to true, only 1 is set to true on the server side. On the client side, the data is array of word. But on the server side, the coils are array of bool. Holding register is array of word on server side. Can this be a problem? Attached screenshot of how it looks at the server side.

Post by ruobian on Analog Input Delay Timer ^{CODESYS Forge talk (Post)}
Hello there, I am new here and in programming. I need help with the basics. I am trying to do what I mentioned in the title. I have an analog input. So I have a real or integer data type value. I want to delay it. TON and TOF only work with bool. I think there is a function block that has two inputs, 1 for real or int and 1 for bool. And if bool is true, it will give the output as real or int. I don't know but I need something like this. Actually, it is not exactly like that. In other words, it will not show the real value at the input at the output after a certain period of time. I want it to show the real value from 2 seconds ago continuously. The purpose of doing this is to compare the real value I received with the value from 2 seconds ago and find out whether it went up or down. I am using only FBD. Please help me with this. Thanks in advance.

Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
All Sensors from the OneWire Master are assigned already to a seperate task with low prio (26) that runs with 1s cycle time. My EtherCat Task is running with Prio 1. It all works fine, until I adjust the CODESYScontrol.cfg or the CODESYScontrol_Usr.cfg files so that it supports a 2nd OneWire Master in the Codeys Runtime. If I change something in this config file and reboot my EtherCat Master stops working.

Post by sturmghost on Visualization using methods and cyclic ST-calls ^{CODESYS Forge talk (Post)}
Im looking for a way to implement ST-code into the visualization element without creating a helper POU or method in my device/application tree. Like visualization properties are evaluated at each VISU_TASK cycle I want to be able to create own ST code which interacts with the visualization interface variables. To be more specific I want to have a property which executes user defined ST-code at each VISU_TASK cycle exactly like its already possible for Input Configuration on various mouse and dialog events. Also a property for initialization (so only executed once) and a timed property would be nice. With the situation right now I'll have to create a POU function which handles the ST-code and misuse a property, like the text variable, to execute this POU function at each VISU_TASK cycle. Or does it exist and I don't know it?

Post by risele on Modbus connection via Qronox PCD3 M6893 ^{CODESYS Forge talk (Post)}
First, if you don't need to change conversion rules in runtime, take a look at "Unit conversion" module (Application -> add object -> UnitConversion). You can specify there biderectional conversion with different units, limits and so on. Second, since MODBUS don't have "real" types but only general 16-bit registers and Real is 32-bit, generally you need a byte-was conversion Real <> two Words. Note, that depending on the devices on both sides, there are two options: Real-> Word1, Word2 or Real-> Word2, Word1, where Word1 is minor register in Modbus register pair and Word2 is major. You can use simple union: TYPE u_Real : UNION rVal:REAL; wVal:ARRAY[0..1] OF WORD; dwVAL:DWORD; //same as previous, may be easier to specify the MB register END_UNION END_TYPE and convert it as following: VAR myUnion:u_Real; rValue_TO_SEND:REAL; rValue_TO_GET:REAL; END_VAR myUnion.rVal:=rValue_TO_SEND; rValue_TO_GET:=myUnion.rVal; Note, that WORD-order should be properly set in MODBUS registers, otherwise you will get strange values. This tool is helpful: https://www.scadacore.com/tools/programming-calculators/online-hex-converter/ Alternative, you can use functions as REAL_TO_DW and DW_TO_REAL from OSCAT_BASIC, for example.
