Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge talk (Post)}
Good morning @eschwellinger, After some research I found out that the problem is the preinstalled CodeMeter on Raspberry Pi. As I mentioned the CodeMeter was installed on the Raspberry because I use a license from other vendor that needs the CodeMeter to be installed. The problem is that when I uninstall the CodeMeter from Raspberry I am able to detect the dongle from CODESYS and everything works as it should be but now the other product can not detect its own license. When I reinstall the CodeMeter I am back to the initial problem. Is there a way to overcome this conflict through CODESYS?

Post by timothyzalusky on Strange Behavior on Raspberry Pi ^{CODESYS Forge talk (Post)}
Hello, I am seeing some weird runtime behavior related to the EQ function on a rapsberry pi based system. I have attached a screenshot showing the strange latching I am seeing on the EQ function, and I have not seen this behavior before. I tried freshly restarting the runtime and it has this same behavior. Anyone seen this? I am on 3.5.20 with the latest runtime installed. Basically, as soon as it hits one of those EQ's in the program, it latches effectively locking the output on. Any input from the Codesys team would be appreciated as well as anyone that might know what I am seeing.

Post by rafael on Wbm/runtime and visualization login ^{CODESYS Forge talk (Post)}
Hello everyone, I’m trying to understand if it is this way or I can change it. I’m making a PLC code and visualization screens, the ideia is to operate via webvisu some controls. So i made a code, made some screens and when i try it in my web browser, first it asks me to insert te user and password of the wbm/runtime of the plc (user: admin, password: wago by default), then i can acess my screens but I have to login again with the user and password that i created in the visualization user managment. My question is: is there a way to disable this first login to the visualization screens (webvisu)? Or create another user/password for this first screen? I have a PFC200 and a Edge Controller, both are working the same way. Thanks in advance Thanks

Post by hwopereis on How to use Application Trigger in Modbus TCP Server ^{CODESYS Forge talk (Post)}
Hi, I'm currently reading and writing several registers with a Modbus TCP server as a subdevice of a Modbus TCP Client. If I read and write cyclically, there are no issues. The problem is this: I see there is also the option to write by "Application", which I would like to use. However, I don't know With the Modbus RTU client, I see there is a trigger variable, xTrigger, to trigger the writing tasks. However, I can't find any such trigger for the Modbus TCP Client. Does anybody know how to implement the trigger behavior for the Modbus TCP client? In particular, I struggle to find the exact "trigger" variable. I'm running Modbus Client version 4.4.0.0 Thanks in advance!

Hi, I'm working with wago 750-8212 controller. I want to change the IP address of the Ethernet adapter from webvisu. I have read some other threads in this forum and I have tried the following: Added the following text to the config file CODESYSControl.cfg: [SysSocket] Adapter.0.Name="br1" Adapter.0.EnableSetIpAndMask=1 Used the below code : IF xUpdateEthernet THEN Ethernet.Enable := FALSE; Reconfig ( xExecute := TRUE, itfNode := Ethernet, eError => ErrorReconfig, xBusy => xBusy, xDone => xDone, xError => xErrorReconfigure); IF Reconfig.xDone THEN ErrorCode := Ethernet.UpdateConfiguredIPSettings(IpAddress := NewIp, gateway := newGateway, subnetmask := newSubnetmask); END_IF IF Reconfig.xDone OR Reconfig.xError THEN reconfig(xExecute := FALSE); END_IF Ethernet.Enable := TRUE; Reconfig(xExecute := TRUE, itfNode := Ethernet ); END_IF I could change the IP address but when i restart my Controller then the IP address resets to the original, Is there anything I have missed, what else can i try ?

Post by xiaolo on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
Does Ver. 4.12 support Raspberry Pi 5? I have three issues. The first issue is that Codesys cannot detect the RPI 5 when I want to download the runtime. When assigning the IP Address manually then I can download the runtime. The second issue is that I cannot connect to the RPI to download a program. Sometimes the window pops up and it ask for the user credentials, but it is still not connecting. The third issue is that I cannot connect to an ESP32 configured as a Modbus Slave with a Raspberry Pi 4B. I can connect to the ESP32 via a Radzio! Modbus Master Simulator. I am also missing the function Write Holding Registers in the setup of the slave. Are this known issues and when it will be solved?

Post by wbj0t on Global variable access by Programms and Modbus Devices (attach device to bus) ^{CODESYS Forge talk (Post)}
Hi everyone. I use Raspberry Pi 4, one core codesys SL. I have a question about global variable access via programm when I glued the same variable to MODBUS SERIAL/TCP DEVICE holding register. So, the question: what behavior of this modifying? When I set "Always update variables (in bus cycle)" and set some task as bus for the Device, then in another task I cant change this varible (can, but immediatly the old value setted again). But the same things works with MODBUS SLAVE: again "Always update..." and master attached to some task, then I change variable in another task and all works. I cant set up my variables from retains file at PrepareStart event because of this behavior with MODBUS SERIAL/TCP DEVICE. Thanks, wbj0t.

Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Hello, I have found a script for printing device tree in Codesys project. This script is available as code snippet as an exmaple for using Python in Codesys. However I feel main documentation is lacking. For example, where can I find that object has "is_device" attribute? Code examples are given here: https://content.helpme-codesys.com/en/CODESYS%20Scripting/_cds_access_cds_func_in_python_scripts.html However, I have a question how to print the whole Project tree and not just devices? Of course I need to remove check: if treeobj.is_device: But simply removing this test condition will not produce what I want. I need to print PLC Logic, Application, ad other nodes in the Project tree. Where to find this documentation?

What i'm trying to do, is to get the name RT401 automaticly into the FB, so i can put this into the string i pass in a struct. So in var in POU, i saw this a place i could do this, RT401: NTC10k(Tag:='RT401'), but i can't get this to work.

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 john-robinson on Limiting Memory Access of an Array to Within its Bounds ^{CODESYS Forge talk (Post)}
Recently we had an issue regarding some simple code to calculate a rolling average. The code indexes from zero to 199 to properly store the current input into a circular buffer which then allows us to calculate a rolling average: VAR input_5s : REAL; outs_arr : ARRAY[0..199] OF REAL; i : USINT := 0; END_VAR ___ //this code runs every five seconds, calculating a rolling average outs_arr[i] := input_5s; i := i + 1; output := OSCAT_BASIC.ARRAY_AVG(ADR(outs_arr), SIZEOF(outs_arr)); IF i >= SIZEOF(outs_arr) THEN i := 0; END_IF There is a simple bug in this code where the index will be set to 0 when it has surpassed the length of the array in bytes (800 in this case) rather than larger than the number of reals in the array (200). The solution here is simple, replacing i >= SIZEOF(outs_arr) with i >= SIZEOF(outs_arr)/SIZEOF(outs_arr[0]). In this example when the index increased to 201 and the line outs_arr[201] := input_5s was called, codesys arbitrarily wrote to the address in memory that is where outs_arr[201] would be if the array was that long. I would like to find a way to wrap the codesys array inside of a wrapper class that checks if an input is within the bounds of an array before writing to that value. I know how I would implement that for a specific array, I could create a method or class that takes an input of an array of variable length, ie. ARRAY[*] OF REAL, but I don't know how to make this for any data type. I am wondering if anyone has ever done anything similar to this, or has any better suggestions to ensure that none of the programmers on this application accidentally create code that can arbitrarily write to other locations in memory.

Post by mubeta on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Thank you for your interest. Your answers are in line with what I knew, so at least it comforts me that I did not misinterpret the situation. However, I don't have an exact match as, for this project over the past few days I have: 1) I have gone back to leaving the various FBs of the motion always called, all of them, and in the state machine I use a boolean to activate the various useful Execute. (But in the future I want to go back and try the programming technique with which I wanted to develop this project); 2) For the occasional error: SMC_FB_WASNT_CALLED_DURING_MOTION perhaps it was due to the fact that I had set the Ethercat bus synchronism only at the CAN master level, but not at the level of individual drives. I have now also activated it for the individual drives and it does indeed seem to have been resolved, but having also adopted the programming technique mentioned in point 1), I cannot say whether this was the solution to the problem, or instead the previous point. Is there an error ‘regulator or start not set’ in the device log before the error ‘motion generating FB wasn't called for at least one cycle’? I can't answer that right now. By now the machine is running and I am no longer there, at this one. Also, I seem to remember that the 'fbeFBerror' drive structure (5-element array), does not cycle, BUT ONCE THE 5 EVENTS AFTER SWITCHING ON, IT DOES NOT UPDATE ANYMORE (but that's another issue), so diagnostics were not easy.

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 spiessli on Softmotion axis to CANopen Maxon IDX drive ^{CODESYS Forge talk (Post)}
Thanks for the advise, indeed, this was somewhat, what my intention was. I tried around again with EDSes and DCFs, anyway. It appears that the DCFs end up in a subfolder in the attach device dialog. Astonishingly, when attaching the DCF version I get a device in the device tree, where I can add a SoftMotion axis, whereas when I attach the device not in the subfolder, then I cannot. Further astonishingly, when looking in the CANopen parameters in supported profiles, "402" is listed in the case of the DCF variant, whereas in the EDS variant "0" is shown. Comparing EDS and DCF files I cannot guess, where the difference is coming from. I cannot tell either why I have always attached the EDS variant and apparantly never the DCF variant. As I am not in the lab right now, I cannot test if the connection actually is working. Thanks again, spiessli

Hi guys, I have a textlist in my project which is working just as expected in a drop down list. I would like to move this text list to a sd card and access it from there, because I want to ease the editing of the contents of this textlist. I'm imagining a solution like the operator shuts down the plant, takes the sd card out, edits the textlist on the card with a windows machines notepad, then reinserts the card in the PLC and restarts the plant, having the new content of the textlist populating the dropdown list. I'm sorry that I'm asking you to spoonfeed me, but I did not find anything straightforward to do this... I saw in the Project>Project settings>Visualisation a relative path thingy, but I have the plant in operation and I would not like to make 100 trial and errors right now... I'm also not interested in SysLib file read commands and stuff, I would just like to access the file from the cards part, I don't want to replace its contents dynamically or such... nor I have language files or recipes...

Post by sigurdrb on send appliaction files to wago plc (codesys 3.5) via ssh ^{CODESYS Forge talk (Post)}
Hi, I was hoping I could send the two files "application.app" and "application.crc" directly to the directory "/home/codesys/PlcLogic/Application" instead of logging into the device with codesys, downloading the program to the controller and then do the "create boot application", so it will reboot with the correct program running. I think i also need to edit the file "eRUNTIME.cfg" located in the "/home/codesys/ folder, because when I create the boot application from the codesys IDE, these lines are added to the file: [CmpApp] Application.1 = Application [SysFileMap] /home/codesys/PlcLogic/Application/Application.app=0x212520, 0x2DBC747E, 2DBC747E.app I think the "eRUNTIME.cfg" file is the same as CODESYSControl.cfg I also dont know the purpose of the hexadecimal numbers etc. that is generated. When I tried to replicate what codesys was doing, I placed the same files in the same folder as when codesys generated the boot file. And also added the lines in the eRUNTIME.cfg file: [CmpApp] Application.1 = Application [SysFileMap] /home/codesys/PlcLogic/Application/Application.app The controller did not boot up with any program, so my method did not work at all. I guess these lines tells the controller to run an application and where to find it? Could any of you help me with the best way to get the compiled program to the controller without using codesys or wago-software?

Post by jackbrady on Function Blocks and arrays of function blocks ^{CODESYS Forge talk (Post)}
Hello, I am new to Codesys and PLC programming in general (please go easy ha!) I'm not looking for code to be written for me just some help and pointing in the right direction. I am writing some code to send commands to a relay based on input values (to put it simply). Quite basic stuff. I have wrote a function block that takes a global variable (Open_command:BOOL) and outputs to another global variable (Opened : BOOL). The function block is simulating a device so I'll eventually get the globals from that. I now need to create multiple versions of this function block/ device (lets say 100) but I need each iteration of that function block to reference it's own relevant global variable. I think that the best way of doing this would be to use arrays, although I could be wrong. I am aware that for up to 100 instances I could very well manually assign everything but that seems rather time consuming and I want a fancier way of doing it. Here is a very basic example of what I am looking to do, please note I have not written this in proper code it's just to show what I mean. Global Variables V[0-100] int Open_command [0-100] Bool Opened [0-100] Bool Function Block var input x : BOOL Var output y : BOOL if x then y = TRUE ELSE y = FALSE The input to my function block will be Open_command, output will be Opened Example code. If V[x] > 10 then Open_command [x] = TRUE ELSE Open_command [x] = FALSE (So when V1 goes above 10 I need Open_command1 = TRUE therefore initiating FB1 output. V2 > 10, open_command2 = True > FB2 output V3 > 10, open_command3 = True > FB3 output ... ... ) What I can't seem to figure out is how to tie all this together, I have read through the codesys documentation and if anything it has confused me more! ha. Apologies for the poorly written post but hopefully you understand what I am trying to get at. Thanks, Jack
