Post by danieldiaz on Problem with FB execution ^{CODESYS Forge talk (Post)}
Hello everyone, I've been working on a system which needs an error function, with this purpose I've created a FB programmed in LD, after debugging I run the simulation. It seems that the variable linked to a coil doesn't change the value when the contacts are associated to input variables. When I use internal variables the logic works properly. I don't know if the problem is related to the variables definition or with the logic program. As you can see in the image, I1 and I2 are variables declared on the FB, the rest are input variables. If I force the eStop and Reset signals to TRUE the coil value should change, but it doesn't. However in the second network if I1 is TRUE the coil change to TRUE as it has to be. To sum up, my doubt is why that coil doesn't change its value? I would like someone to shed a light on this. Thanks!

Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Yes, I tried to do what you put in the first code. However, I have a problem with that and that is that the inputs must be declared with the type. I have many data types running in my code (real, int, uint, bool) and I can't put them in the same function, another thing is that I need to instantiate that function for everything I want to write to the slave. You put a for to 200 but it means that it has to be the same data type and inside the array, but I want to get them individually. I'm struggling to do it in a good and efficient way like wago's E-cockpit does. in the first screenshot you can see, you simply type in value, change the package of things you want to write in value change and it does everything by itself automatically, without comparing any old and new values and even less having the need to activate a bool. , it is perfect.

Post by squiggleypuff on Can't Add New Version of Modbus TCP Master ^{CODESYS Forge talk (Post)}
I'm having a tough time trying to get Modbus working on a Festo CPX-E PLC; it throws these pre-compiler errors as soon as I add in my Modbus TCP Master 3.5.12.30 to my project: I'm confused about the C0046 error, as I have IODrvModbusTCP 4.3.0.0 Library installed. So I thought maybe I needed to use the newest Modbus TCP Master 4.3.0.0, which is in my device repository: However, whenever I go to add this underneath the Ethernet adapter (which is version 4.2.0.0), the only TCP Master version available is the old 3.5.12.30 one, even if I have Display all versions checked.: I even went so far as to delete the old version, but then there were no options to add a Modbus TCP Master under my Ethernet adapter. What needs to be done to use the newest Modbus TCP Master? Or are these pre-compiler errors unrelated and I'm missing something? Any help greatly appreciated.

Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge talk (Post)}
Hello mates, I'm working with CODESYS V3.5 SP20 on a Raspberry Pi and I use "Raspberry Pi MC SL" as device on the project. I've installed the Control Standard L (multicore) license on a Wibu System usb-Dongle (cmStick/4.50) that already had another license from another vendor. I follow the online activation procedure from CODESYS documentation. Raspberry Pi has already CodeMeter installed for the other license. When I plugin the dongle on Raspberry and start the Runtime from Raspberry Pi Update in CODESYS I receive the message that I'm on Demo mode because the license is missing. I double checked that the license is activated in the dongle, through the WebAdmin of CodeMeter and the second license runs properly without any issue. I have already try to change the dongle from HID to MSD device and backward but the the Runtime cannot recognize the Dongle. I have also try to stop and start the Runtime through CODESYS without success. Is there anything else I can do to fix this issue?

The hole setup is made by 3s. So its a comination of one not two. If Epis decide not to support extra licence whats then the funtion of providing an option with a single license ?? So the idee by 3s has a flod. Epis change the system to add the Stick. I send controller inc stick to Epis. On my software i can see the stick. An then you tel me i need a other license to use an license ?? Makes completly no sense. Codesys should be flexible but is not. I tried Delta. But has no HMI and has its own Codesys ?? Why ?? Then i tried Crist. The block there own system by a password. But dont know the password and cant switch it off. At the end the want me to pay for support to solve ther own made problem. So i send it al back. The extra license is adviced by 3s . Now a few month later still no working solution.

Post by william-blandon on RecipeManCommands.ReloadRecipes ^{CODESYS Forge talk (Post)}
Hi Dave. Thanks for your answer. I still struggling with this. I have done everything according with the Codesys help even I have looked in detail at the example. I have double checked the recipe manager configuration and the use of all the methods. There are two methods that do not work as expected. I'm using Codesys 3.5.19.20 and recipe management 4.4.0.0 .CreateRecipe just create a recipe in the recipe definition but do not create the file. This have a walk around just giving a .ReadAndSaveRecipe afterwards. .ReloadRecipes do nothing but do not generate any error as well. After calling it I call the .GetRecipeCount and the number is always 0. When I create a new recipe (using the function block methods) then the number changes. Looks like this method is looking to the wrong directory finding nothing. I don't know if there is a missing configuration in the CODESYSControl.cfg file. I'm thinking in a walk around for this but I need to create a strings array with the recipe names as retentive and making all the management when deleting and adding recipes. Have had some one the same problem?

Post by caprez95 on Deleting the trend recording history ^{CODESYS Forge talk (Post)}
Hallo Ich möchte eine laufende Trendaufzeichnung stoppen, den Inhalt löschen und Trend-Diagramm auf 0 zurücksetzen. Laut Codesys soll das mit dem folgenden Code möglich sein: You can insert an input element in the visualization which the operator can use to delete the previous value recording in the trend visualization at runtime. The curve displayed until then is removed and the display starts over. In the application (example: in the program PLC_PRG), implement the following code: itfTrendRecording : ITrendRecording; itfTrendStorageWriter : ITrendStorageWriter; itfTrendStorageWriter3 : ITrendStorageWriter3; sTrendRecordingName : STRING := 'TrendRecording'; itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); xClearHistoryTrend: BOOL; IF xClearHistoryTrend THEN itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); IF itfTrendRecording <> 0 THEN itfTrendStorageWriter := itfTrendRecording.GetTrendStorageWriter(); IF __QUERYINTERFACE(itfTrendStorageWriter, itfTrendStorageWriter3) THEN itfTrendStorageWriter3.ClearHistory(); END_IF END_IF In the visualization of the trend recording, add a button for deleting the previous curve. Configure its Toggle property with the variable PLC_PRG.xClearHistoryTrend. ⇒ When xClearHistoryTrend is set to TRUE, the previously recorded curve is deleted. The recording immediately starts again. Dies löscht auch die Daten vom Trend, aber das Diagramm wird nicht auf 0 zurückgesetzt, sondern läuft einfach da weiter wo man gestoppt hat. Braucht es für den Diagramm-Reset noch einen zusätzlichen Befehl? Gruss

Post by timvh on Toradex and CODESYS and licensing ^{CODESYS Forge talk (Post)}
For the Virtual Control you need to use a "Network license". The Virtual Control has parameters of which one is the reference to the license server. This can be the device itself, but you need to activate the license on the host system (not in the container). For this, CODESYS has a Network License server with WBM (web based management). See for the Network License configuration: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_license_controller_linux.html If it is only for evaluation, I would advise to use a CODESYS (USB) key and activate the license on the key. Then you still have to install the CODESYS Network License server on the host, but you don't have to activate the license as soft license on the device. The benefit is that you can easily move your license to another device when needed. Off course your device must have a free USB port available to be able to do this.

Post by gatto on Backtick identifiers ^{CODESYS Forge talk (Post)}
Hello, I’m in Codesys 3.5.20.40 and I try to declare the variable ´var1´ but I get an error. here : https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_rules.html i read : Backtick identifiers By using backticks, characters can also be used in identifiers that are not normally permitted in identifiers, such as special characters. The acute accent character is used for backticks: ´ (Unicode: U+02CA) The use of backticks is recommended in order to be able to use the same identifiers in CODESYS as in other programming languages or documents, such as circuit diagrams. Any character may be used between two backticks, except line breaks and other backticks. Keywords are also allowed as identifiers between backticks. Examples: ´Variable+9´ ´INT´ The backticks are part of each identifier and therefore var1 and ´var1´ are two different identifiers. Example PROGRAM PLC_PRG VAR var1 : INT; ´var1´: INT; END_VAR var1 := var1 + 1; ´var1´ := 12; Are there any limitations or is something missing in my development environment?

Post by jonasz on Deploy LicenseServer for Linux SL ^{CODESYS Forge talk (Post)}
Good morning, I'm digging into this topic because I'm curious about resolving my problem in a test environment. In my previous message, I asked about the CODESYS Safe Timeprovider SL package (4.18.0.0), which I saw in the illustration. I noticed that it runs as a service. I am asking about this because from the perspective of an "ordinary" user, this service provides easier access to the settings of the time provider's operating parameters. The basic time provider configuration is outlined at https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_virtual_safe_time_provider.html. Why my questions? They stem from my specific case, which is experiencing timeout issues. I know that my environment is currently only a test environment. I'm assuming a real-world scenario in which I won't be able to achieve a better result with my configuration, and I will ultimately need to increase the time provider's cycle time. By running the time provider service, I can easily influence the time provider's operation and thus eliminate the problem. I know, I know, safety systems are not life-enhancing extras.

Post by jroddball79 on PM556-TP-ETH — How to change IP address without overwriting the PLC program? ^{CODESYS Forge talk (Post)}
Hi, I need to change the IP address of an ABB PM556-TP-ETH using ABB Automation Builder. The situation is: I have connectivity to the PLC using the current IP (configured in Communication Settings) Online Login works fine The Network Scan does not detect the PLC IP-Configuration tool shows all fields disabled I don't have the original project source, only an empty project The PLC has no SD card inserted The Online menu does not show an Upload option When I modify the IP in the project and connect, Automation Builder shows: "The PLC configuration needs to be updated. A full PLC download is required" I'm afraid a full download will overwrite the running program. Is there any way to change only the IP address without overwriting the application? I'm also open to solutions using third-party tools, Python scripts, or any other method (DCP protocol, direct TCP communication, etc.) as long as it doesn't overwrite the running application. Thank you

Post by manuknecht on XY Chart causes extremely long cycle in Visu Task ^{CODESYS Forge talk (Post)}
I am using the visualization element "Cartesian XY Chart" in a visualization template within a library to display recorded position values. I managed to configure the chart as desired and it displays the values like it should. A problem occurs when clicking on the chart to move the cursor, zoom or pan. Upon clicking the visualization element for the first time, the task in which the visualization is run spikes to a cycle time of around 5'000 to 15'000 ms (the configured cycle time is 100 ms). Sometimes this even completely crashes the web-visualization. After this very long cycle, the visu task normalizes again and the chart can be interacted with as usual. Another spike in cycle time occurs once the visualization is switched to a frame that does not contain the chart. I did reduce the data array to only a few values and tried changing the update behaviour of the chart, but it did not change the problems I am facing. Did anyone experience a similar issue or even has a solution for this?

Post by risele on Modbus connection via Qronox PCD3 M6893 ^{CODESYS Forge talk (Post)}
You are welcome. Also note, that it's valid only if you modbus-device use same real/float value representation (IEEE 754). That's true for most of systems. But some devices may have other representation, such as integer + position of the decimal point, for example 123.456 is integer = 123456 and position = 3 Also note, that, ones again, depending on endianess of each system, you may also need to swap not just words, but bytes. TYPE u_Real : UNION rVal:REAL; wVal:ARRAY[0..1] OF WORD; bVal:ARRAY[0..3] OF BYTE; dwVAL:DWORD; //same as previous, may be easier to specify the MB register END_UNION END_TYPE than swapping may be something as VAR A,B,C,D:BYTE; //Bytes of the real value uIn, uOut:u_Real; rVal:REAL; ModbusReg1,ModbusReg2:WORD; END_VAR uIn.rVal:=rVal; uOut.A:=uIn.D; uOut.B:=uIn.C; uOut.C:=uIn.B; uOut.D:=uIn.A; ModbusReg1:=uOut.wVal[0]; ModbusReg1:=uOut.wVal[2]; Or you even need to reorder bits... Ones again, sending float/real values is not defined by Modbus protocol itself, so it is hardware- and software-dependent. The Modbus Poll (and most of modbus tools) have configuration parameters that will properly swap bytes on their side. Ones again, that's very helpful: https://www.scadacore.com/tools/programming-calculators/online-hex-converter/

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 george32 on CSV file and string manipulation. ^{CODESYS Forge talk (Post)}
Dear folks, I think I have a rather simple question but I could not find the right answer to my question: I have made with Excel a CSV file where I would like to have some general data regarding my program variables. I have made an program what let me read the file. The string I am currently get is at follows: 'IP_Adres;192.168.45.12$R$NPort_number;2000$R$NCycle_time;43$R$NStart_Standard_IO;20$R$N' Now I want to split the string in multiple part, which I later would connect to the right variable. By Google and experimenting I have reached to the following code for the first part of the splitting proces: // Splitting the BOM of the string: Received_string := FileReadString; IF LEFT(STR:=New_string,3)= '' THEN Received_string_without_BOM :=RIGHT(STR:= Received_string,SIZE:= (LEN(STR:= Received_string))-3); END_IF //Splitting the remaining string in part for later declaration. WHILE index = 0 DO index_split_part := FIND(STR1:= Received_string_without_BOM,STR2:= '$R$N'); Part_of_String[index]:=LEFT(STR:=Received_string_without_BOM, SIZE:= index_split_part); index := index + 1; END_WHILE However in the splitting proces I could not understand what is really happening. I understand that the Find() function returns the first value the $R$N in the Received_string_without_BOM. This would mean that the index_split_part := 23 I|P| _ |A |d|r|e|s|;|1_|9 |2 |. |1 |6 |8 |. |4 |5 |. |1 |2 |$ |R |$ |N |P | 1|2| 3 |4 |5|6|7|0|9|10|11|12|13|14|15|16|17|18|19|20|21|22|23|24|25|26|27| So the next part is to read the first 23 characters of the Received_string_without_BOM with the LEFT() function. I expected that the outcome the following was: 'IP_Adres;192.168.45.12$'. However the outcome is: 'IP_Adres;192.168.45.12$R'. I do not understand where the R after the $ sign comes from, because its place is 24 so it would not be added to the part_of the_string[index]. If I hard coded value 24 for the size it gives me the following return: 'IP_Adres;192.168.45.12$R$N'. I would expect everything till the R but the code adds the $N also to the string. I hope someone could explain to my what I am seeing wrong in my point of view? With kind regards, George

Post by mondinmr on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Good day, I’m writing this message out of frustration regarding the current way project files are saved as encrypted XML and single-file format in CODESYS. I find this approach to be quite tedious for several reasons: Limited Access to Structured Text: Not being able to access Structured Text (ST) externally makes it impossible to work with alternative editors like VSCode. Tools like VSCode are incredibly responsive and feature advanced systems such as GitHub Copilot, which would be a real game-changer when working with ST IEC. While CODESYS works well for small code snippets or debugging, when the codebase grows, switching to VSCode to boost productivity becomes essential, and copy-pasting between environments is a cumbersome workaround. Poor Integration with Git: This file format also makes it very difficult to integrate effectively with Git. I have tested the internal demo, but for advanced merges, it is unusable. Without properly formatted plain text, it’s impossible to leverage the vast ecosystem of external tools around Git that allow smooth merges in heterogeneous teams. File Corruption on Network Drives: I often work from multiple locations with shared network drives. When the development environment saves a file and something goes wrong midway (which can occasionally happen when using VPNs and network drives), the entire project becomes irrecoverable. There’s no way to cancel the save process, and the development environment freezes. This has happened to me at least four times over the past two weeks, and one of those incidents cost me an entire day of work. All of this is particularly disappointing because I truly believe that the libraries, runtime, and overall work done by CODESYS are exceptional. I find it fantastic that there is a platform allowing development of PLCs and control systems using OOP, which is a huge advantage in modern control engineering. I apologize for the rant, but this issue has been extremely frustrating. Best regards.

Post by struccc on Application failing to boot after system reboot ^{CODESYS Forge talk (Post)}
I started to experience the same issue, after upgrading to 3.5.19 , and still persists with 3.5.20.3 , using CodesysControlWinV3 x64 on Windows. Unfortunately, this is a live application, normally it is running for months without interruption - so it was a surprise at the last cold start... It was not possible to go online with the original version, so I couldn't see the application, or system status, just the log message. First time I manually clean the Application from the PlcLogic directory (there was no coredump file in there), then I could start the runtime service, and do a fresh download, and set the bootproject. I could not try a cold system reboot - it's in a 24/7 production environment, and I was under heavy pressure to start... What I did, I have created a backup from the * complete * runtime directory, from the failed, and fixed version - before and after download. This directory in my case C:\ProgramData\CODESYS\CODESYSControlWinV3x64\55096128 - At the next shutdown, it was sufficient to copy back this backup completely, and could start the runtime service afterwards. Ugly, but local staff with some skills can do it without programming tool... I don't store any live data, configuration, log files, persistent data in this directory - the only reason I need this is to edit the CodesysControl... .cfg file.... And to see the logfiles in emergencies like this. The application concerned doesn't use any retain area. - exactly for these reasons - Maybe that is causing the problem with the newer runtime versions As far as I see, this problem occurs only if the power of the Windows PLC is interrupted without a proper shutdown. Unfortunately, this can happen sometimes. The newer versions, seems tp modify CodesysControl.cfg on the fly, and register the applications, and bootproject information after download. (I don't really see CodesysControl.cfg a proper location for this... but that's just my feeling) So now I had a look at CodesysCotrol.cfg on my laptop and I found: [CmpRetain] ;Retain.SRAM.Size=0x200200 ;Retain.SRAM.Address=0xFA3C5776 ;SimulateSRAM=1 [CmpApp] ;Bootproject.CreateOnDownload=0 ;Bootproject.StoreOnlyOnDownload=0 ;Bootproject.InvalidateByRename=1 ;Bootproject.InvalidateBySetting=1 ;Bootproject.InvalidateNever=0 ;PersistentForce=0 ;RetainType.Applications=InSRAM ;RetainType.Applications=OnPowerfail ;RetainType.Applications=None ;Exception.Hardware.GlobalStop=1 Application.1=MyTestAppNoRetain The last line appeared after download and boot project creation. Maybe... Should set RetainType.Applications=None? I wonder about all these settings, but... Will write separately about it. I hope this helps a little...

Post by ofey on EtherCAT fieldbus ^{CODESYS Forge talk (Post)}
Hi, everyone! I'm trying to set up a PLC controller and a connection to an EtherCAT slave device in Codesys. I want to create a flexible program that I can upload to multiple controllers with different remote IO connected (same program). On one plant i may have 5 AI-cards and 3 DO-cards, and on another I may have 4 AI-cards and 2 DO-cards. For not needing to maintain several different programs wih different devices defined in the program (one for each set up) I thought that using a remote IO would make it easier having a single program. That way I could refer to different memory addresses instead of predefined slots/channels and IO's, that would give me errors if there was a different IO on the plant than what the program expected. When I tried setting up the etherCAT master, I saw that I had to define the etherCAT slave devices with the different IO'cards for me to be able to refer to the memory addresses in a PRG. Exactly what I was trying to avoid. My setup is something like a program that can handle 16 separate pump controls. In a year maybe 6 plans get deployed, and depending on how large the project is, the number of pumps can vary between 4 and 16. And the managers dont want to have IO's for all 16 pumps on every cabinet, and I dont want to maintain 16 separate projects files in case of updates etc. I thought the best way to tackle this was having a single project that read/write data to the different pump IO's by remote IO (fieldbus ethercat) addresses. And the number of pump controls are activated by an external GUI. If pump 1-6 is activated by the GUI, then the PLC-program tries to read/write input/outputs from predefined addresses for the expected IO's. My test setup is a PFC200 WAGO controller and a EtherCAT fieldbus coupler (750-354) with some IO. I hope I didn't explain this too horrible, and if there is a more easy and elegant solution for this challenge I appreciate a feedback on this.

My questions If DSEServiceTool shows Status OK and package ACK, but the device still says “No application loaded”, does that mean: the .pkg was transferred but not accepted as a valid application? the package was built incorrectly? the boot application / runtime / firmware versions are still mismatched? What is the correct procedure to generate CodesysApp.pkg for M840-02 V4.1? Is there any known compatibility issue between: DSE CODESYS Package 1.5.44 M840 MKII Firmware 4.1.2 CODESYS 3.5 SP12 Has anyone successfully loaded even a minimal empty test project into M840-001-02, and if so, what exact versions/process did you use? Any help would be appreciated.

Post by darko7417 on When running as a service, CodesysControl doesn't write log files to the disk (and other CmpLog related issuess) ^{CODESYS Forge talk (Post)}
I run CODESYS runtime as a service and use CmpLog (the LogAdd2 function) to log different events to a file. I have done this many times before on various projects and hardware, and it works fine. On this particular system, I have CODESYS 3.5.20.40 running on a Windows 11 PC. The CODESYSControlService autostarts (with Local System credentials, the default), and the application runs fine. However, the configuration file is not read (or at least not the one that should be, or not the CmpLog section), and log files are not written to the disk. I would be thankful if anyone knew why this is happening and how to fix it. A note to CODESYS people: you must provide more information on the codesys configuration file, CODESYSControlService.exe and other major components and system behaviour. You created the service and various features (i.e. logging), but haven't explained how they work, which, in my opinion, is below standard for industrial automation software. These are my observations: - When running as a service, the config file is not read (none of them), or at least the CmpLog section is not read. I checked the log using Codesys IDE, and the CmpLog parameters are not the ones I have set in any of the config files. Which CmpLog config values does the service use, and where does it read them from? I have no idea, but it's not the config files. Here are the codesys config files I located on the PC's disk: o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\CODESYSControl.cfg (only 2 lines in this config) o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\AppDataFiles\CODESYSControlWinV3\CODESYSControl.cfg o C:\Users\SRV\AppData\Roaming\CODESYS\CODESYSControlWinV3\C4DBB537\CODESYSControl.cfg o C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\tempCFG\CODESYSControl.cfg - When I run codesys as an app (e.g. by clicking the icon), this config file is read C:\Users\SRV\AppData\Roaming\CODESYS\CODESYSControlWinV3\C4DBB537\CODESYSControl.cfg and log files are written ok. The icon target is "C:\Program Files (x86)\CODESYS 3.5.20.40\GatewayPLC\CODESYSControlService.exe" -d o the -d option, I think, starts a cmd-like window showing service debug output (the output shown in log in the IDE) o the -i option, again I think, means install the service - I tried adding -d to service start parameters in the registry, but it started only once and after that it refused to start. Knowing what -d does and which other options are available would be great (e.g. can I make the service read a different config file). - Syslog UDP logging works fine in any case. - These are my CmpLog parameters ~~~ [CmpLog] Logger.0.Name=PlcLog3 Logger.0.Filter=0xFFFFFFFF Logger.0.Enable=1 Logger.0.MaxEntries=10003 Logger.0.MaxFileSize=50003 Logger.0.MaxFiles=33 Logger.0.Backend.0.ClassId=0x0000010B ;sends logger messages to SysOut Logger.0.Backend.1.ClassId=0x00000104 ;writes logger messages in a file Logger.0.Backend.2.ClassId=0x00000135 ;sends logger messages as UDP syslog Logger.0.Type=0x314 ;Set the timestamp to RTC ~~~
