Post by srouse on Adding a Softmotion License to a Weintek HMI ^{CODESYS Forge talk (Post)}
I am trying to add a Softmotion license to my Weintek HMI. The HMI is already licensed for Codesys and I have already purchased a Softmotion license as well. When using the License Manager I get an error saying the licensing info is not available. I am fairly new to working with Codesys so I am at a bit of a loss and there seems very little information online about troubleshooting this specific issue. I have attached the error message below. If there are any ideas of how to troubleshoot this better I would be happy to hear them.

Post by sigurdrb on Read codesys version in the codesys application ^{CODESYS Forge talk (Post)}
Hi! I want to read the codesys version into the project, so I can highlight it in the SCADA system. VAR dwVersion : DWORD; END_VAR SysTarget.SysTargetGetVersion(pulVersion := ADR(dwVersion)); This gives me the value 100859909. I tried to search ths up and found som older post (https://forge.codesys.com/forge/talk/Runtime/thread/a55981ff4d/) that said each 4 bytes reads a number in the version. Example is 50662666 = 16#03050D0A which reads to V3.5.13.10 When I run this code I get the value 100859909, which I cant translate to anything meaningful. I am running it on Codesys V3.5.19.70. Help appreciated!

Post by george32 on TCP Server ^{CODESYS Forge talk (Post)}
Dear people, I would like to create a TCP server in my PLC program. The TCP server needs to communicate with an external device. I have been searching the internet and found that the libraries Syssocket or CAA NetBaseSrv are two possible solutions to create a TCP server. From what I have read, CAA NetBaseSrv is more user-friendly to implement than the Syssocket variant. However, I am still struggling to actually implement this library. Foremost is my little knowledge about creating a TCP server and how to read/understand each function block, especially the outputs of some blocks and the types, e.g. server has an output CAA.Handle, but I cannot find the explanation of CAA.Handle. I tried to find a good document that can help me understand how to implement a TCP server, but I could not find it. Thank you in advance, George

Post by struccc on Multiple applications on one device sharing variables. ^{CODESYS Forge talk (Post)}
I don't exactly recall where (I think some release notes), but I read the information that this multiple application / sub application feature is to be discontinued. Please, correct me, if I'm not right about this I am a bit sad about that - I was using that feature with more or less success. However I understand the reason behind the change: it introduces huge complexity, especially when dealing with multicore and safety support... AS I understand, it's to be replaced with the new virtual plc architecture, and standard ways for synchronizing / sharing data... So, for now the "Add application" context menu item was removed, but behind the scene it is still supported... Hint: if you still want to experiment with it, might try copy-paste things within the PLCLogic tree...

Post by george32 on Learning ST in an object-oriented way. ^{CODESYS Forge talk (Post)}
Dear all, I am currently creating a program in the ST language. Because the program is starting to grow nicely I would like to switch to a more object-oriented way of programming. (Like for example in Python). By surfing the internet I found out that Function Blocks is the best method for this. Now I would like to delve further into this, with all the possibilities that Function Blocks have only I cannot find a clear course, explanation of what everything is around the function block thing and how to approach everything. I find the standard documentation around Function Blocks rather abstract and the examples are minimal. Therefore I am looking for a page/course/document explaining object oriented programming in Codesys (or other PLC programming environment). Do you have any recommendations on this?

Post by joanm on Programmatically change the IP addresses of the Modbus TCP slave devices ^{CODESYS Forge talk (Post)}
Hello all, I am working in a project in which there are multiple Modbus TCP slaves. I need to be able to change the IP addresses of those devices from the HMI and I was planning to use the process depicted here: https://faq.codesys.com/display/CDSFAQ/Modbus+TCP+Slave%3A+Dynamic+Setting+of+the+IP+Address I can see the port number is what is used to specify which slave device we want to modify the IP address of. This said, can I freely set arbitrary port numbers to each device? I mean, can I set the first device to be at port 502, the second one at port 503... Any drawback or restriction? Is there any other way to reference to the device without having to change the port numbers? Thank you all in advance.

Following up on the invalid user authentication on the target Not 100% sure what the problem was but following my post I managed to create an administrator level user. Then my next issue was that I could not connect to the device. I might have flipped the device from a 64 bit version to a 32 bit version so I did UPDATE DEVICE back to the 64 bit version; still could not connect somehow. Then I did two things at the same time that fixed my problem: Wiped the Codesys Control Win 64 bit version and installed the 32 bit version Installed latest Codesys Control Win V3.5 SP20 (released today) I wish I knew which one of these actions fixed the problem but at least the problem is solved. Hoping this post may help someone one day

Post by dhumphries on How to determine code size ^{CODESYS Forge talk (Post)}
I'm trying to determine which Codesys Control license I need, the Control Standard S has all the features I think I'll need, but the code size is limited to 3mb, I created a simple program with only 1 line of ladder logic and a simple visualization with a button and an indicator. When I generate code I get some messages, one indicates that the total allocated memory size for code and data is 2.1mb. Is this metric the correct size of the code? I question the size because it exceeds the allowable code size for the Basic S and Basic M licenses and consumes 2/3 of the available memory for the Basic L or Standard S license. What tool can I use to estimate the size of code as it relates to the runtime license limit?

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?

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.

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

There seems to have been included an updated in the last release 4.9.0.0 or am I wrong (I think I tried out these settings previously without giving the result I wanted contrary to what I see today)? Now an empty check box for "display variable name" is effective, and will present the Variable with the "Description" instead. Perfect! Seems to be some minor formatting still that needs adjustment. See attached screenshot. The apostrophe "'" between "description" I suppose should not be there? Also I guess the same apostrophe (although not visibly shown) gives an extra space between the variable-description and the ":"?? Thanks!

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 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 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 madskaizer on Task Priority Documentation? ^{CODESYS Forge talk (Post)}
Hi All I was watching the Wago PFC300 webinar ( https://www.wago.com/global/lp-thank-you-onlineseminar-pfc-300 ), and the presenters comment about priority 1 being way above the Ethernet task priority, so that a priority 1 PLC program can actually loose SCADA connection, made me try to round up some hard evidence on Codesys Priorities. I find there is very little information on "correct" task priority configuration. There is a lot of different hardware manufacturers, using Codesys Runtime, that has different descriptions in their manuals on how to set up priority. https://doku.amk-motion.com/en/Subsystems/PDK_202975_A-Serie_en/Content/Projekt/AMKAMAC/PDK_202975_A4-A5_Produktbeschreibung/Funktionalitaet/PLC-Programming/PLC%20Tasks.htm?TocPath=PLC-Programming%7C_____7 https://product-help.schneider-electric.com/Machine%20Expert/V1.1/en/SoMProg/index.htm?#t=SoMProg%2FTask_Editor%2FTask_Editor-7.htm&rhsearch=priority&rhhlterm=priority&rhsyns=%20&SUBSTRSRCH=1 https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_f_task_configuration.html So my questions :) 1) If there is only 1 PLC_PRG task, does priority matter? 2) What is the priority of Ethernet / communication, if nothing is entered? 3) What is the priority of Codesys OPC UA server? 4) Some users here on forge mentions that Wago PLC programs should run as priority 11, but where does this recommendation origin from? 5) What are you recommendations for a relatively slow process, like building automation? It uses OPC UA for communication to SCADA, maybe some MODBUS-RTU and MODBUS-TCP, usually around 100 I/O, been running with everything in a single task at priority 1, 50-100ms cycle time. Some controllers have separate MODBUS tasks, but doesn't seem like a big difference. How would you recommend splitting up communication, IO fieldbus and programs into differently prioritized tasks? I know its a complex matter and all about my application, but I really miss there was just some kind of guidance in the documentations and with all new standard Codesys programs having priority 1 as default, makes it seem less important, than it really is.

Post by patrik on Wish: CODESYSControl.cfg - again ^{CODESYS Forge talk (Post)}
Really good post. I hope that it gets seen by CoDeSys staff. I often find the documentation lacking when it comes to using CoDeSys in more complex ways. If using standard "basic PLC functionality", then it's fine and functions are documented in a sufficient way. Once you go outside of that bubble then I find the documentation not enough. CODESYSControl.cfg is a good example of this. And why isn't more of this integrated in the IDE. like changing port of the webserver. Why is it hidden in this file and not accessible through the IDE. It feels like a layer of complexity purposely left in so you don't change it if you don't know what you are doing. Like the argument is if you have the know-how to find the file you have the know-how to edit it. I find the documentation lacking when it comes to more complex libraries too. Like the element collections library. there is parameters I still don't quite know what they do. I can't find any documentation about them. There is an example project to download from CoDeSys so you can see how you are supposed to set your factories up. I leave some parameters like it is in the example. Should I? I don't know. Does it work. Yes. But I could perhaps create memory leaks if I get something wrong and I don't see that until way later. In the create method of your element factory you have a function called __vfinit and you just have to accept that it works. Why can't I get insight in what it does through documentation? Don't CoDeSys want us to know how these work so we can't use them to accidentally break something? I find the error logging lacking too. I've had the CoDeSys service crash but it doesn't say why. I've seen windows noticing the crash but no error code was sent or error message. Also in my current issue where the application fails to start after power outage. I can see in the log that it fails to load retain in the application as one log entry and application failing to start as another. But why? Why does loading the retain fail? give me more information! Is it just a skill issue with me? I don't know. If it is then I'd still want CoDeSys to step up their game when it comes to documentation. I'm sorry if a lot of frustration comes though in this post. I really like the product and what I can do with it compared to other PLC brands.

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.
