Post by salvadegianluca on SysPlcCtrl23 and C0338: The library 'cmperrors interfaces, 3.5.5.0 (system)' is supported just in 32 bit applications ^{CODESYS Forge talk (Post)}
Good afternoon to everyone; I'm stuck with this error and I don't know how to get out from it... I tried several time googling for alternative systems to control the PLC applications and resets but without success. I would like to realize the possibility to reset the CPU and to start/stop the applications as it was possible with the SysPlcCtrl23, but this library is no longer supported in 64 bit systems and it seems due to the cmperrors interfaces sub library that was included in the above said one. Someone found a work around for this issue?

Post by mborchert on PFC100 Error "Bus not running" ^{CODESYS Forge talk (Post)}
Hello, i currently want to use a wago 750-8102 with the "codesys control for pfc100" runtime. I want to add the devices connected to the internal pfc100 bus via the "search devices" tab. This was reccommended in the following thread: https://forge.codesys.com/forge/talk/Deutsch/thread/7701332199/ But whenever i try to search for devices codesys just doesnt find anything and i cant close the "search devices" window. Has anyone got an idea what the problem might be? I already tried adding the devices connected to the pfc100 manually but the bus just doesn´t start. best regards Moritz

Post by kazuhiro on Problems using MySql Library and SysProcessExecuteCommand2 together ^{CODESYS Forge talk (Post)}
I use fbMsSQL_compact(FUN) of the MySQL Library to write data to the database. There is no problem when writing data using only fbMsSQL_compact(FUN). However, when I try to write data obtained using SysProcessExecuteCommand2 to the database using fbMsSQL_compact(FUN), an error message "Dest server on ip address:xxx.xxx.xxx.xxx and port:1433 is unreachable" appears and writing is not possible. From what I have researched, it seems that writing is not completed in one cycle of fbMsSQL_compact(FUN), and when SysProcessExecuteCommand2 is executed first in the second cycle, the work done in one cycle of fbMsSQL_compact(FUN) is reset. Could you please give me some advice?

Post by ron-rp on Errors with VisuUserManagement library ^{CODESYS Forge talk (Post)}
Hi all, I've played a bit with the VisuUserManagement library, and some other security option in my project, and I started getting this error when logging in - see attached pic. something to do with a specific screen in the library - VUM_Login. Also, Codesys started to ask me to log in to the library when logging in, asking to log in as user of the groups Maintainer or Owner, which I dont know either users (attached pic). when I close the login screen and try to log in to the PLC again, everything works again until I close and open Codesys. I do use user and password to login to the PLC, and this login screen is fine I know the user and pass I setup. anyone know what did I do wrong here and how to fix it?

Post by pazderai on CanOpen write issue ^{CODESYS Forge talk (Post)}
Thank you for an answer. Unfortunatelly, it doesn't work. The slave needs command byte as follows 0x22. It means expedited transfer where s-bit is not set, therefore data length is not specified. If I use segmented mode by CiA405.SDO_WRITE_DATA it produce command byte as follows 0x21 which is unfortunately supported by the slave and it returns with error 0x05040001 - SDO Abort Code -Client/server command specifier not valid or unknown. I can use CAN API low level to overcome this problem where it is possible to set 0x22 as a command byte, but than I can use user interface to set the communication probably, because I thing that machine expert uses library CiA405.SDO_WRITE for setting the slave. Or am I wrong?

Good day I would appreciate it if you can give me some advice on how to fix my "Bus Not Running Error". I am Using Codesys 3.5 SP20 and Codesys Control PLCnext SL V4.12.0.0. Codesys control was installed on the device and I can log into it but it seems that it does not pick up the PLC or the IO attached (Please see attached Image). The Bus Cycle Task of the AXL F 2152 is set to Main Task and the "Always update Variable" is Enabled on each IO Module. My Main Task interval is set to 100ms and Priority is set to 0. I have tried other options and none seem to work. Your response to this issue will be highly appreciated.

Post by opineiro on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
Hi, I have an issue with a function which sends a message through API Rest. I'm using a function from httpCLient library. I have tested this function inside a program and it works fine. But when I want to use it inside a function (so I can call it simultaneously from 2 different points on the main program) it gives a stack overflow error. In detail it says: "C0297 Stack Overflow on Main Task. Stack sizes... Call hierarchy:" I have simplified as much as I can the function, but I'm hitting a wall with this. Anybody has an idea of what's wrong? Thanks!

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 pierre on difference between stub file and source file in scriptengine ^{CODESYS Forge talk (Post)}
I included the stub files of scriptengine (codesys python api) in a directory scriptengine of a project. I tried to include librarymanager like that: from scriptengine import librarymanager visual studio code detected an error. It said librarmanager could not be found. Indeed in the stub file, this was library_manager. But if I change it in my code, the plugin doesn t work anymore. I found an easy solution to this problem. I ve just changed the copied stub files.(library_manager -> librarymanager) But I think it would be better if you update it yourself in the future.

Post by jacobwago on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hello, I have experienced the same issue as described above but for the Modbus Serial configurator. Looking for a solution. In v3.5 SP19 Patch 7 the Modbus Serial Master Slave configurator has a "virtual" limit of 10 channels. In v3.5 SP18 Patch 5 this virtual limit does not exist. I can successfully copy back and forth from 18 to 19 with out any build error. However, this is not a good solution for our customers. What is even more confusing is that the IoDrvModbus library is the same version (4.3.0.0) for both SP18 and SP19. Please help in providing a fix to the virtual channel limit of 10 in SP19. Thanks,

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 sigurdrb on Codesys and error messages, warnings exceptions etc. ^{CODESYS Forge talk (Post)}
Hi, I tried some different libraries (CmpApp etc.) to find some global variables that I could read out as a variable in the codesys environment. Do any one of you know which libraries are best suited for this, and how I can read it out? My goal is to send messages, warnings etc. to the system that communicates to the PLC. Currently if something goes wrong I need to see the logfiles, or go online with the controller. I think I could save a lot of time if I could read the errors from our user interface that is connected to the PLC by TCP/IP.

Post by yannickasselin on MQTT QoS 1 & 2 ^{CODESYS Forge talk (Post)}
Hello, After some more tests, here is what I found out. It seems we have to increase the uiKeepAlive and tPingInterval parameters. If I increase the uiKeepAlive value to 60s and the tPingInterval to 30s, then if I disconnect the ethernet cable from Codesys and publish some messages to which Codesys subscribes to and then reconnect within 30s, I will get the messages. If I don't reconnect the cable within 30s (ping interval), the client goes in error with "ACKNOWLEDGE_TIMEOUT". When this happens, it will not automatically reconnect after reconnecting the cable. I have to disable and re-enable the client but I will not get the published messages. I need to do more tests because there are a lot of weird things happening when playing with the ping interval and the keep alive. It is not clear to me what does what. I even ended up not receiving messages anymore, even if I disabled and re-enabled the mqtt client. The client did not give any error. The only way I was able to get messages again was by modifying my client ID. After that, if I try to re-use one of the old client IDs, nothing works (publish, subscribe) and I get a TCP_INIT_ERROR and sometimes a TCP_READ_ERROR. I need more explanation/documentation about these weird behaviors. Maybe it is the way I use it, maybe it is related to the broker (I am using Mosquitto with default parameters). When using a Node-Red client, everything works perfectly. I am trying to achieve the same behavior with Codesys but it seems impossible so far.

Post by t-probst on Strong Private Key Protection for Encryption Certificates ^{CODESYS Forge talk (Post)}
Hello, We are trying to implement an automated method of adding of a certificate and private key to the Windows certificate store for encrypting CODESYS projects. We want to do this so that users do not have to deal with details of certificates at all and to prevent user error. We are keen on enforcing strong private key protection since it ensures that a password is required for the certificate to be used to decrypt a CODESYS project. When we add a certificate to the certificate store and enable strong key protection using the Microsoft Management Console Certificates snap-in, it works as expected. However, through this method the user may mistakenly not enable strong private key protection. For the certificates we create programmatically (using Microsoft’s Cryptography Next Generation API in .Net 7) bag attributes are added to the certificate and key by the API. These bag attributes are as follows: Bag Attributes localKeyID: 01 00 00 00 subject=C = xx, ST = xxx, O = xxx, OU = xxx, CN = xxx issuer=C = xx, ST = xxx, L = xxx, O = xxx, OU = xxx, CN = xxx -----BEGIN CERTIFICATE----- [encoded certificate] -----END CERTIFICATE----- After using this certificate with bag attributes to encrypt a CODESYS project, it can’t be decrypted, showing this error: "The specified project could not be loaded. Possible reasons might be: - The project file is corrupted or invalid - The project has been saved with a newer version of the programming system. If this is the case, you can open the project in the corresponding version. Choose "Save as..." with the appropriate storage version, and retry again. - You may not have the necessary permissions to lad the project" We know that the bag attributes are causing the issue because if we manually edit the certificate file to remove them before using the certificate to encrypt a project, the project can be decrypted as expected. However, we are unable to automatically enforce strong key protection using this method. Here is a link to a StackOverFlow question that we have posted recently for this issue: https://stackoverflow.com/questions/76922355/enforcing-strong-private-key-protection-for-x509certificate2-objects-in-net-mod Any help is greatly appreciated.

Post by alex-at-xana on EThercat Dynamic configuration ^{CODESYS Forge talk (Post)}
Hi Everyone, For a fast monitoring system I am using Ethercat oversampling and timestamping inputs. As the customers has a lot of different configurations out in the field, we went for a dynamic Ethercat configuration. Already got the whole detection chain working but now I am stuck since two days in debugging the configuration. Here are my quesitons: I extended the dynamic config example for the EL3632 16#0E303052: //EL3632 pSlave^.SetDCSettings(TRUE,TRUE,80,80,TRUE,4000,0,0); pSlave^.AddSyncManager(16#1000,128,16#26,TRUE,3); pSlave^.AddSyncManager(16#1080,128,16#22,TRUE,2); pSlave^.AddSyncManager(16#1100,0,16#4,TRUE,1); pSlave^.AddSyncManager(16#1110,214,16#20,TRUE,0); pSlave^.AddFMMU(0,214,0,7,16#1110,0,1,1); pSlave^.AddFMMU(0,1,0,0,16#80D,0,1,1); xKnown := TRUE; This leads to a PLL Error for these devices. I double and triple checked the configuraton, but cannot find the issue. There seems to be one difference: the config dialog creates a startup parameter: 16#10F3:16#05, Name: Command_0, Value:0. Bitlen: 16, Stop on fault: false, jumpt at fault: false: next line: 0 a) I do not find information on how to set this in my code. Can you help me there? b) Without trying to set the value, I get a PLL error for these devices in the master log. Is the config wrong? c) Do I need to set the Master to Autoconfigure or Manual? I used autoconfigure for my tests. The stack creates input data addresses for the slaves input data range (pSlaves[i].InputData) which are different from those created when I use the Engineering tools dialogs to configure Ethercat. Specifically, the addresses seem to be aligned at 16 byte boundaries when they are created using the engineering tool, but may appear at uneven addresses when I use the script in dynamic config. I did not try to access ULINT at uneven addresses yet, but I am suspecting this may be a problem. Do I need to manually align the addresses ? Any help is appreciated...
