Post by jrsantab on Remote connection to ifm PLC & HMI ^{CODESYS Forge talk (Post)}
We have finally solved the problem. The version of the Gateway in the computer that worked (3.5.11.0) and the one that didn't (3.5.17.30) was different. We have three different Codesys 3.5 versions installed because we work with different controllers. I believe that, depending on the sequence you follow to install the versions you get a different Gateway version. To solve the problem you first have to disable the "obsolete" services. Open services, serach for (in our case) CODESYS Gateway V3 Version 3.5.11.0 CODESYS ServiceControl Version 3.5.11.0 I stopped the services and changed to Manual Start. Then you have to create the new services. In our case, from a Command Prompt session (cmd): SC CREATE "Codesys GatewayService Rigual" binpath="C:\Program Files\CODESYS 3.5.17.30\GatewayPLC\GatewayService.exe" and then SC CREATE "CODESYS ServiceControl Version 3.5.17.30" binpath="C:\Program Files\CODESYS 3.5.17.30\GatewayPLC\CODESYSControlService.exe" remember also to set them as Automatic Start!

Post by rringo on Function block not autofilling ^{CODESYS Forge talk (Post)}
I am attempting to place a block and make it an Analog sensor. When I go to change the name like in the instructional video on youtube it does not give me an option to autofill the block with a known configuration. This is a problem I have in Codesys 2.5 and 3.5. Did I mess up the install of the program or need to install a library? Any help would be appreciated. https://www.youtube.com/watch?v=PkJYQeIUmIM&t=136s at time mark 2:15ish The first image is what I can do and the second is what the videos function autofills to.

Post by jerry-sorrells on Find Function: Object reference not set to an instance of an object. ^{CODESYS Forge talk (Post)}
Build: CODESYS 3.5 SP19 Patch 1 (64-bit) Host OS: Windows 10 Target: Linux SL I have a project with programs in Structured Text and Ladder Diagram. When I try to use the Find function, it works for the Active Editor; however, when I try to use Find for the Entire Project, I get the error "Object reference not set to the instance of an object." I know what this error means in the context of the program, but I have no idea why the find function is returning this error. The variable I am searching does not matter: it happens with all variables. Any help with this will be greatly appreciated. I generally use the Find function quite often as I am developing and not having it is really slowing me down.

Post by lukebouchard on NVL generating ADwin packets instead of UDP? ^{CODESYS Forge talk (Post)}
Using Codesys 3.5 SP11 32bit to program a pair of IFM CR711S controllers. They each have an NVL sender and are set up to receive each others messages. One is transmitting properly but not receiving, the other is receiving the first's messages just fine. When I look at the traffic in wireshark, I can see the one transmitting properly as UDP packets on the subnet and port I had specified. The Second is transmitting on the right subnet and port, but is sending 'ADwin Config' packets. Has anyone run into anything simmilar? From some reading on ADwin from google, nothing is enlightening. Both are set up in the same way, have their own ports and List Identifiers. I have deleted the NVL files and regenerated them, cycled power, and even deleted and remade the NVL's so many times.

Post by jari-koivuluoma on Newly created texlists wont appear in the selection dropdown ^{CODESYS Forge talk (Post)}
When I create a new textlist in Codesys 3.5 SP19 Patch 5, it wont appear in the dropdown menu at Rectangle element > Dynamic texts > Text list. If I just type the name of the textlist to the field (in quotes), I get an error saying that some file is missing. Any good ideas what to do and what is going on. I recently updated to that version and I only now noticed this when I needed to add a new textlist so Im quite screwed with this not being able to add text lists. While im typing this, I tried copying an existing list and modifying it and it seems to show. Any ideas?

Post by pedegani on "Do you really want to perform" dialog boxes ^{CODESYS Forge talk (Post)}
I have the same annoying problem. The confirmation prompt for every single action appeared recently after an update from CODESYS 3.5 SP20 Patch 3 to Patch4, but I don't think it's due to this. Having to confirm every operation while debugging an application is a considerable waste of time and does not help at all to concentrate on development, not to mention that many times you miss the long-awaited event because you are busy looking for the 'yes' button to resume debugging or force a variable. Does anyone know how to disable the confirmation messages?

Post by peterkcontrols on Copying 2 byte word to output ^{CODESYS Forge talk (Post)}
Hello. I am using codesys 3.5. I would like to know if it is possible to set a variable to an output without declaring in. I have defined a STRUCT and within this struct I have a Struct for inputs called I and a struct for outputs called O. I have declared a variable of the type of this Struct, I would like to set or alias the value in this variable to an input/output value of an IO block that has a module on the ethernet tree. Is it possible to copy the contents of %IW0 -> STRUCT.I ? The size of both of these is 2 bytes. I understand that I can declare a variable with the input like Input01 AT %IX0.0 : BOOL; However how can I make STRUCT.I.D00 AT %IX0.0? Is this possible? Thanks

Hallo goodmorning, I am using codesys 3.5 sp19 with Weidmueller PLC. I created a page with several checkbox to manage an array of bool. When I build the project the system doesn't signal any error, when I go in simulation mode everything works until I click on checkbox to toggle the variables. Other visu elements works proprerly (e.g. bottons, lights, ect, ect) but the check boxes cause a crash giving the following error: Error while processing the visualization: Client id not present or no longer valid I serched to figure the problem out and to search a solution on the web but nothing. Can someone help? Thanks and Regards, Scanu

Post by fenicklar on Login problem with FileTransfer on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
Hello everyone, I'm currently trying to set up a FileTransfer function from a Webvisu to my Raspberry Pi 5 on Codesys 3.5 SP 19 Patch 6. I went in the files CODESYSControl.cfg and CODESYSControl_User.cfg and added : [CmpWebServerHandlerV3] AllowFileTransferServices=1 And it seems to be working. However, I cannot access my several Webvisu without putting my login. That's a problem because one of my webvisu is in kiosk mode on the raspberry itself and there is nokeyboard attached, it's just an information screen, but I can't view it. Is there a wey to enable the File Transfer without requiring to login ? Thank you for your time
