Post by k2saki on CNC Open Source Project / Can I convert my project to text-files ? ^{CODESYS Forge talk (Post)}
Hi. I published My CODESYS-CNC Project to GitHub and I set it Open Source Software. Here https://github.com/k-s-saki/RPi_CODESYS_CNC My CNC Project is binary file , using FBD for IPO , so I found it is a little bit hard to work with people on GitHub. (diff / merge ) My question is 1) Is it possible to convert my project ( only POUs is also fine ) into text file ? How? 2) Would it be better to rewrite all FBD/LD into ST and copy them manually to text files? Thanks.

Post by fpawlak on KNX SL on stock PFC200 firmware ^{CODESYS Forge talk (Post)}
Hi All. Is it possible to use CODESYS KNX SL on stock Wago firmware (Codesys version, not e!Cockpit). I have Wago 750-8212 with firmware 0.4.04.03(26). When I tried to run 'KNX SL' or even 'Device Reader', I have got [FATAL ERROR] Unresolved reference: 'CODEMGETCONTENTBYFIRMCODE3' [FATAL ERROR] Unresolved reference: 'CODEMGETCONTENTBYFIRMCODE2' [FATAL ERROR] Unresolved reference: 'CODEMGETCONTENTBYFIRMCODE2' What probbalby means that there is no running CodeMeter component on PLC. I have checked /etc/codesys3.d/CODESYSControl.cfg [CmpWebServer] WebServerPortNr=58080 [CmpSecureChannel] CertificateHash=86ccf31839a098ee32067179e26600f1bd6b36f8 [CmpUserMgr] AsymmetricAuthKey=a9d38381e75bbf1bbfc8749e97f536f68238a2ce So the question is if I can somehow add Codemeter to stock firmware? Or should I switched to CODDESYS Control for PFC200 SL or application-base runtime licence?

Post by dhumphries on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
Thanks for the response, as I've thought about this problem over the last month I began to suspect this was a problem with not being able to exactly represent .1 as a 32 bit binary number. I think I've found a work around by making the number an integer, then dividing it by 10 and storing that value as a floating point number. There is still an issue with the value not being exact somewhere in the 8th or 9th decimal place, but because I'm incrementing an integer value then dividing it, the error doesn't compound.

Post by damian177 on CM4S GPIO's in Codesys ^{CODESYS Forge talk (Post)}
Hi, I am running my application on device based on Compute Module 4S (Cortex-A72 (ARMv8) 64-bit ). On this device I installed RPi Runtime in 4.11.0.0 version. In my project I use device: Codesys Control for Raspberry Pi 64SL and my project works, but I actually do not have acces to all GPIO's , because GPIOs Compute Module is available only in 3.5.16.0 version and it doesn't work. Properly work GPIOs B+/Pi2 but using this device I do not have acces to all GPIO's in CM4S. Anyone of can tell me how add GPIOs Compute Module 4.11.0.0 to my project ?

Post by jaspergain on Non-existing identifiers ^{CODESYS Forge talk (Post)}
Hello, I got a bit of a weird issue going on which is kind of annoying. So recently we switched a lot of Modbus IO to EtherCAT, as we were having issues with stability. All works fine, which is great. But sometimes when I change the program I get errors claiming that identifiers are not defined. Meaning I can't go online. See the picture below. I believe this is because some of these identifiers were used with Modbus, and they weren't properly removed/deleted? A clean all temporary fixes the issue, but it comes back again after a while of changing the code, and building. Any way to fix these non-existing required identifiers, or even find out where they are required? Thanks for the help in advance. Jasper.

Post by spice on WebVisu Recipe Save/Load ^{CODESYS Forge talk (Post)}
I'm currently reworking the controls on a cnc press brake and wanted to load various recipes as programs to run. I'm using a 2d array of REALs to store the X and Y coordinates as well as some other program parameters in a recipe. I'd like to store all of the recipes on a computer used as the HMI that way the text files can be edited and uploaded offline. I'm using Automation Directs P2CDS-622 Can this be done through webvisu? If not would a license for Codesys HMI SL on the computer allow me to accomplish this? I've attached the Project File Thanks, Spice

Post by fajean on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
4.11 appears to solve the problem. Thanks for your help. I had first installed the 64-bit version of RPiOS, but looking at various posts and the product's page on the store which only lists 32-bit compatibility, I downgraded to the 32-bit version. I did this before trying 4.11, and it did not solve the problem. Thus my working system is 32-bit, and I am wondering if I can go back to 64-bit or not. An 64-bit OS is not listed as compatible on the store's web page, but when installing there actually is a 64-bit version listed (automatically chosen when installing on 64-bit, but otherwise greyed out). Is 64-bit supported and the website is out-of-date, or is that some kind of work-in-progress?

Post by gatto on Modbus tcp - channel ^{CODESYS Forge talk (Post)}
Hi can you give more details? Are you talking about a danfoss? wich model? Can post the configuration of channel' I used, on the past, serial modbus with danfoss fc280 I remember ((id x 10)-1) I remember that you couldn't use continuous reading/writing of the directors but you had to use them one at a time. it seemed that reading empty registers (caused by x10) was not accepted by danfoss. So I had created a scan that used just one register, then the next etc etc with a timed interval. But this was for the serial, I don't know if it's the same thing with ethernet. I currently use Ethernet TCP/IP interface with FC280.

Post by rcanfield on Code Coverage and Test Manager ^{CODESYS Forge talk (Post)}
I am exploring the possibility of measuring test coverage using the Test Manager and Profiler tools. It appears there are some significant limitations. Has anyone been successful trying to use these tools? Here are my observed limitations. Am I misunderstanding anything? * Profiler only works for one "run cycle". Even warm resets will clear the coverage calculations. Thus, all tests would have to manually reset values when complete to prevent contamination to other tests. * It is not possible to see which statements were/weren't executed. One would have to use the flow control tool which cannot be used in conjunction with the Profiler, and must be viewed in realtime. * The profiler control cannot be automated and therefore must be executed through a manual procedure. Thank you!

Post by hyys12 on How to use/create SOTU in LD program ^{CODESYS Forge talk (Post)}
I am trying to make a LD program for an existing installation with a motor. Here an inductive sensor is used to give an input, as a check to verify the conveyor is actually running. Here the plan was to use a TOF timer which gets constantly reset when the sensor input gets detected. The problem is, that if the conveyor is stuck, and the sensor sends a continous signal, the timer will never do what it is supposed to do. Therefor I need some help on how I can convert the input to a pulse, with the help of something like a SOTU. I just cannot find this in codesys anywhere.

Post by amy123 on Alarm Manager Example Alarm Client doesn't Populate ^{CODESYS Forge talk (Post)}
Hello, I tried to run the example project from https://forge.codesys.com/prj/codesys-example/alarm-manager/home/Home/ However, I can not get the interface for Alarm History 12 Alarm Manager client to populate with any alarms. 'udiResult := AlarmManager.g_AlarmHandler.RegisterClient(itfAlarmManagerClient12, ADR(arritfAlarmsFromHistory12), iMaxCountAlarmsFromHistory12);' when I look at itfAlarmManagerClient12 its always empty. What is confusing is that when I simulate 2 alarms, iCountActiveAlarms 12 has a vlaue of 2, associated with itfAlarmManagerClient12 - so that appears to work. And yet, its useless as the ProcessAlarms Function can't extract anything from the empty array. I dont understand how these arrays are supposed to be populated and why its not working. Any help would be greatly appreciated!

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.

Post by peterned on Array to String ^{CODESYS Forge talk (Post)}
max. string length in Codesys is 255 chars. It's not possible to cram 20,000 things in a string. If you need to send the data to another device, send the whole data[] array (as byte array, without doing anything to it) and extract the information on the other end. As each struct member has a fixed size (81 bytes, as per you declaration), this will be easy. To save some resources, consider declaring string lengths - e.g. if the max possible length for key is 10 chars, declare it key: STRING(10); and it will occupy 11 bytes instead of 81

Post by abrarsk on SysCom Library Usage ^{CODESYS Forge talk (Post)}
Hello all, I am facing issues with using SysCom library. With SysCom23 library things were simple but since we are migrating to 64bit systems, I am writing a Porting program. With SysCom23, opening the comport was as simple as providing the ComPort no. which returns the Handle as a DWORD. dwHandle:=SysComOpen(Port); But the new library is a bit different. It is asking for 2 input parameters to open the Com Port - Port Number and POINTER to RTS_IEC_RESULT IF hCom = 0 THEN hCom := SysComOpen(ComSettings.sPort, ADR(pResult)); How should I use the RTS_IEC_Result? I can find RTS_IEC-REUSLT under SysType2Interfaces of SysCom library. Also, can someone give me a general understanding of this RTS_IEC_REULT and RTS_IEC_HANDLE, etc.?

The description of the function create_pou() doesn't specify the correct arguments requested, it only says create_pou(type: SpecialPouType) and a script using the documentation definition of the function will raise an error.

Post by paulpotat on Exclude traces when searching with ctrl+F ^{CODESYS Forge talk (Post)}
Hello, I was wondering if there is a way in codesys to exclude the traces from the search when using the "ctrl+F" window ? That would be nice to improve the search functionnality when looking for a specific variable. Sometimes when I iterate through all occurences with the "find next" button, it opens the trace configuration window. I would expect to be able to close it and go to the next occurence with the "find next" button, but after closing the trace configuration window the search says it has reached the end of the scope (even if in reality there are other occurences of the variable elsewhere). I tried to enable / disable the "search up" checkbox but it's not changing anything. I hope somebody have insight on this, BR

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 c3po on SNMP Communication with WAGO 750-8212 PFC ^{CODESYS Forge talk (Post)}
Hello folks, my problem is a bit bigger for just one question. So let's start with the easiest. But first, my system setup: It's a WAGO 750-8212 PFC with some I/O-modules. I try to communicate with the controlsystem over SNMP using the IIoT library from codesys. https://content.helpme-codesys.com/de/CODESYS%20Examples/_ex_iot_snmp_service.html Is there some expirience with this kind of communication? It's just about transfering some data from PFC to network and setting some analogsettings from network to the PFC. So my easiest question: Do I ever need the SNMP_Agent or can I use the SET / GET function as standalone, without the agent? (maybe some more questions will follow, if someone will answer to my request) thanks so far
