Post by kleeswi on SysFileOpen does not work after update to V3.5 SP19 Patch 5 ^{CODESYS Forge talk (Post)}
I use the function SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_WRITE, pErrorFileOpen); to open and write a file. Since the update from Codesys V3.5 SP17 to V3.5 SP19 Patch 5 it does not work anymore. I first had SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_APPEND_PLUS, pErrorFileOpen); in both versions. hFile_Test is a pointer to byte. It gives an exceptional error when dereferencing the hFile_Test pointer. Edit: I use Codesys on a Raspberry pi

Post by ofey on EtherCAT fieldbus ^{CODESYS Forge talk (Post)}
Okey, thank you! Do you think it is something in this library, that makes it possible to do the configuration in a PRG? https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/IoDrvEtherCAT.html#id1 I think the codesys modbus libraries support configuration and connection to modbus slaves without having to add the slave devices in the device tree. Just do it from function blocks inside the program. I was hoping for something similar with EtherCAT.

Post by corriibme on Setting array values with JSON Utilities SL ^{CODESYS Forge talk (Post)}
It turns out that you can build JSON structures without ever calling the JSONBuilder function block directly. Instead, create a pointer to JSON.JSONData and invoke the necessary methods on its dereference. The parent object has a parent index of -1 (and an index of 0). EVERY other item (including keys, values, empty arrays and sub-objects) created by the setX methods needs the index to increase by 1. Then use the JSONByteArrayWriter FB to generate your JSON string

Post by plunje on Sensor not set ^{CODESYS Forge talk (Post)}
A got a larger project but this very small example makes it clear. I have a button, and after it's clicked a lamp should flip on and stays on, and when the mouse-button is released it should stay on. When I try that in the PLC_PRG it works, but when I change it to a function block (seet attched demo proj) it isn't. I'm fairly new to PLC programming but are very experienced C# engineer, but this goes above my head...

Post by swe-hob on call of a method of a function block in another program ^{CODESYS Forge talk (Post)}
Hi, Let's assume following: PRG_1 fb_1 : fbExample1; fb_1.method_1 do something... PRG_2 fb_2 : fbExample2; fb_2.method_2 if xTest then PRG_1.fb_1.method_1(); end_if; Is there a reason why runtime hangs when I call the method_1 in PRG_1 from a method in PRG_2? Both programs run in the same task. No chance that any other program calls the method. What I practically do there is that in the program PRG_2 I add a structed object into a buffer. In PRG_1 I just process the items in the buffer.

Post by joep on Custom robotics kinematics model debugging ^{CODESYS Forge talk (Post)}
When trying to move my axis using any group move instruction I get the following error: SMC_CP_INVALID_PATH_ELEM and axisgroup goes into errorstop state. I tested my methods thoroughly which makes it hard for me to debug. Are there some hidden rules I need to abide to? How would one go about debugging a custom robotics model, since the information inside isn't accesible. Is it possible to find the source of where the function breaks? Any hint in the right direction would be appreciated. Best regards

Post by timvh on OSCAT Scale_r function not working in LD 4.60 works in LAD2 on 3.5.21sp3 ^{CODESYS Forge talk (Post)}
It seems like a bug in FBD. Work-around: If you click on the small line between the box and the output variable and delete this, the variable is removed. When you then assign a variable again (Ctrl-A), then you will see that the line will be a bit longer. If you then select the previous variable, you will see that it works.

Post by youness on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
I have Already the same problem when i'm trying to write data more than 10 times in the same file. In fact, i send my data periodicaly to a file that i configured to have permission of W/R in my CodesysContol.cfg. When the Error occurs, i must reboot my machine to success. It means that the problem isn't realted to a limitation of size, but a problem in the function supposed to handle the file. totorovic : allow me to know if you've found a solution to your problem. Thanks.

Post by nxbp on About Compatibility ^{CODESYS Forge talk (Post)}
Let's say I have a CODESYS controller (PLC) with a runtime version around 3.5.19. If I use development software version 3.5.21.40 or a later version that will be released in the future for programming, could there be any problems or malfunctions in the controller's program execution or in the execution of the new, updated function blocks from the newer software? I mostly work with servo-based motion applications, so please keep that in mind when answering, and provide a detailed answer so I don't have to email you again about this topic.

Post by durallymax on VAR_INFO from inside of a FB to get info on the instance. ^{CODESYS Forge talk (Post)}
The help link appears to be broken. When I implemented something similar I had to add {attribute 'reflection} above the declaration of the FB with {attribute 'instance-path'} above the string VAR that would contain the path. Then wrote a function to trim off however much I wanted removed by searching for periods, then formatting it with spaces at the periods and removing brackets on arrays while also breaking up the PascalCase to present it a bit nicer for the end-users.

That's what I found as well Shaun. I have seen it at least in versions 3.5.21.1 and 3.5.21.3. There seems to be an issue with the FBD/LD package v4.6.0.0. The workaround proposed by Tim works but needs to be done manually on every code change/addition. For now we manually downgrade the FBD/LD package from v4.6.0.0 down to v4.5.0.0 after installation of CoDeSys. Same as you did. I hope this gets fixed on a next patch.

Post by timvh on KeyPad Function in Visualization to fill a table ^{CODESYS Forge talk (Post)}
Create an array of STRING and 1 INT variable, e.g.: asMyString : ARRAY[0..9] OF STRING; iIndex : INT; Then place a "Table" object in the visualization: - link this to the string array variable. - Check the option "Use Template" - Then in the Input Configuration - add the "Write Variable" command Somewhere else add a "Combobox, array" - link this to the same array. - And link the index to the INT variable. In the Combobox, you can then select one of the strings from the array. The index variable will indicate which selection has been made.

Hello at all. After un upgrade of "CODESYS Control for Raspberry Pi MC SL" from v4.7 to v4.9 SysFileOpen function stopped working. I'm not able to read or write files from the PLC application. Before this upgrade all worked fine. I've read this thread [ https://forge.codesys.com/forge/talk/Engineering/thread/3da9ded84e/ ] Despite I followed that indications I couldn't get my code working again. Perhaps I'm missing something or I didn't understand how to use placeholders at all. Is there a different syntax to use for "SysFileOpen" in order to use placeholders? Thanks in advance for your help.

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 julianramirez on ModbusFB write update ^{CODESYS Forge talk (Post)}
Hello everyone, I am testing the ModbusFB library tcp server and so far I am able to create holding registers successfully, however, I am trying to identify after each write which registers got updated (i.e. function code, write value). I can even see the var udiNumWriteRequests, which increases with every write. I noticed that there is logging with the LogStatusInfo method. After I call it I am able to read in the console stuff that I want. Nevertheless, this is only available at the logs and is not easy to decode because it consists on several messages, I would like to know if there is a way for me to retrieve this information from the function itself with pointers or if there is any way to copy the logs messages (assuming that I can filter them with the LoggingOptions to only show what I need) inside the runtime code and not in the console. Thanks for your help :)

Post by hyys12 on Help understanding analog in-/outputs ^{CODESYS Forge talk (Post)}
Hello. I am currently working on a WAGO PLC, where I am trying to wrap my head around how the analog inputs and outputs work in codesys. I have looked far and wide on the internet, for a general introduction to the whole concept, but I have not had any luck with finding anything that helped me understand it better. The whole goal is for me to be able to read an analog input from a temperature sensor, as well as using an analog output, to control a frequency inverter. I know these have nothing to do with each other, but that is all I have on hand right now. I am trying to program this using Ladder Diagram. The only thing is, that every video/guide I have seen/read using LD, just adds a whole lot of function blocks, to do all kinds of stuff they don't explain. My general question is, how would one go ahead and read the analog input, as well as transmit an analog output? Is there some kind of specific function block I would have to use for this, or some great video I can watch, to understand the inner workings. Is it somehow possible to see the values the PLC recieved/sends? Regards.

Post by atcprojectteam on Modbus Function Code 15, writing multiple coils ^{CODESYS Forge talk (Post)}
Hi all, I am using an RSTI-EP I/O card along with the EPXMBE101 Modbus/TCP network adapter. I have a Control Standard L license. I successfully connected to the I/O card via Modbus and can read inputs without any issues. However, when I try to write to the digital output modules using function code 15, I am unable to make any changes. Here’s what I have done so far: I created a small project using Structured Text. I set up Modbus channels (as shown in the attached image) and mapped the pins. When I use cyclic mode, the connection results in an error. However, when I use the rising edge, the connection works, but I don’t see any changes on the I/O card. For the output module, I assigned one bit to high. After that, I ran CODESYS Control Win V3. (Should I be running the PLC as well?) I built the program, but I am not receiving any response from the I/O card. Could you please advise on what might be causing this issue?

Post by ph0010421 on How to create a stopwatch? ^{CODESYS Forge talk (Post)}
Do you need an 'hours-run' counter? And 1 second resolution is ok? I think you're over-thinking it. (The task time needs to be < 1second) Have a look at the LAD... Then, the time in seconds can be made into hh:mm:ss with this FUNction Declarations: FUNCTION funSecondsToStringTime: string VAR_INPUT InSeconds: UDINT; END_VAR VAR AsString: STRING; Minutes: UDINT; Hours: UDINT; Seconds: UDINT; MinutesAsString: STRING(2); HoursAsString: STRING(2); SecondsAsString: STRING(2); END_VAR and the code: Hours := InSeconds / 60 / 60; //Derive hours Minutes := (InSeconds - (Hours * 60 * 60)) / 60; //Derive minutes Seconds := InSeconds - ((Hours * 60 * 60) + (Minutes * 60));//Derive seconds HoursAsString := UDINT_TO_STRING(Hours); MinutesAsString := UDINT_TO_STRING(Minutes); SecondsAsString := UDINT_TO_STRING(Seconds); IF LEN(HoursAsString) = 1 THEN HoursAsString := CONCAT('0',HoursAsString); END_IF; IF LEN(MinutesAsString) = 1 THEN MinutesAsString := CONCAT('0',MinutesAsString); END_IF; IF LEN(SecondsAsString) = 1 THEN SecondsAsString := CONCAT('0',SecondsAsString); END_IF; AsString := CONCAT(HoursAsString, ':'); //assemble string AsString := CONCAT(AsString,MinutesAsString); AsString := CONCAT(AsString,':'); AsString := CONCAT(AsString, SecondsAsString); funSecondsToStringTime := AsString;

Post by wbj0t on mobus tcp slave device. read/write holdings with 2 variables. ^{CODESYS Forge talk (Post)}
Hi there. I have an issue to read and set time for the controller. In the issue many registers described as writable by 6/16 functions, and, in this time, also(!) readable! For example: I have time registers: min, hour, day, mon, year. By specifications it is possible check time (so I need always update these varibles in loop) and set time by writing these same registers, BUT how to set, if they will immediatle updated by current time after writing? So, I need to separate one address at two variables. I have seen option mark: Overlay of the process image by the holding and input register. I understand this so: When I READ by function 3, I will get variable that connected with the same INPUT address and when I WRITE by 6/16 this will change second variable that connected with HOLDING address. BUT, this mark doesnt work, when I write 6/16 and try to get by function 3, I will get written value instead INPUT variable. So, what to do?

Post by sanacfu on looking for v2.3 libraries on v3.5.19 ^{CODESYS Forge talk (Post)}
Hi all, I'm new to Codesys and Wago but well versed in Rockwell. I've been tasked with upgrading old Wago 750-880 PLCs that run Codesys v2.3. All I was giving is the original PLC program in v2.3 and the currently running machine. I've spec out to what I believe is a suitable upgrade, the PFC100 2ndGen, 750-8111. As I'm rewriting this code on the Codesys I can't find the same library functions blocks for ethernet settings PLC functions. Currently I'm working on code to get/set the PLC ethernet IP address and HMI IP addresses from the HMI screen. One other function I'm looking for is a warm reset function to the PLC. When googling for this stuff I see a lot of code not in ladder logic. Are these functions now not available to implement in ladder logic? Where can I get more information on finding and implementing this functions? Do I have to buy a license from Codesys to use these functions? The PLC I ordered should be arriving in 2-3 weeks.

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 aris on Modbus write via FB failure ^{CODESYS Forge talk (Post)}
Hi all, I am using CoDeSys V3.5 and a soft controller Win V3x64. I am trying to read a modbus slave via Function Blocks and not via the channels of the hardware tree for the Slave. I created some requests of type ModbusRequest and I notice that I can read Input Registers and Coils but I can not write Holding Registers and Coils. I am using the library IoDrvModbusTCP 4.1.0.0. When i just use a single modbus request with FC06 (or FC16), there is no request sent to the slave and although the xExecute takes its true value from a pulse of 2 seconds duration, I take almost every 3 minutes an error "TCP_COMMUNICATION_ERROR - 16#A5 - TCP Port. error. Request was not sent". My code is ok because if i change the function code for reading registers, everything works fine. Did anyone have this issue in the past? Thank you in advance.
