Post by carohe on VisuNamespace != null ^{CODESYS Forge talk (Post)}
Hello, this error occured frequently over the past couple of weeks. I found out, when adding a webvisu, CODESYS added Visu libraries in the library manager. One of the libraries was the "VisuElemsAlarm" library. In my case it added this one with the version 4.3.0.0. However another library that also contained the "VisuElemsAlarm", used the "VisuElemsAlarm" with the version "4.4.0.0". After changing the Version "4.4.0.0" and uninstalling this version, the error has not occured anymore. Regards, carohe

Post by sachem on SysFileGetTime problem ^{CODESYS Forge talk (Post)}
Good morning. I'm working with a Weidmuller controller using Codesys. My project use OPC-UA to communicate an application in my pc with the controller. Yesterday, I installed the license of the controller and test it, and the communication works perfect. I use the communication with anonymous login, and works fine. But, hours later, the anonymous login don't work, and the controller only allows connection via OPC with username and password. Someone know why this happend? Thanks

Post by rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hello Vincent, I don't have 75 channels but it works for me as described above without any problems. There is also a parameter MAX_MODBUS_CHANNELS in the library parameters for the IoDrvModbusTCP module. The default value there is 100. Perhaps you are reaching the limit there? The value can be adjusted accordingly. I assume that this value is not accepted in the input dialogue and therefore the 'fixed' limit value 10 is used.

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 i-campbell on Publish a JSON payload via MQTT Publish (using IIot Libraries) ^{CODESYS Forge talk (Post)}
your are sending as a WSTRING which is UTF16, but your receiver is interpriting as UTF8. Change the receiver to use UTF16, or better change your sender to convert to UTF8. You publish the entire storage space (SIZEOF) Instead of the number of bytes of actual text (StrLenA) try using utf8JsonData : STRING(2000); JSON.Stu.ConvertUTF16toUTF8( ADR(wsJsonData), ADR(utf8JsonData), SIZEOF(utf8JsonData) ); and change your publish to mqttPublish( mqttClient:=mqttClient, pbPayload:=ADR(utf8JsonData), udiPayloadSize:=To_UDINT(JSON.Stu.StrLenA(ADR(utr8JsonData))), wsTopicName:=topic, mQTTPublishProperties:=mqttPublishProperties );

I was looking for a transpiler from some more widely used general programming language into ST. It was not easy but I found this :) https://forge.codesys.com/tol/c2iec/home/Home/ Does anybody use it for a programm/library of a couple of hundred lines or more? How does one go about using the output? Is there a “converter” into the Codesys IDE? PLCOpenXML? Would there be interest in this? tib0r

Post by valenting on Problem with Licenced Software Metrics ^{CODESYS Forge talk (Post)}
Hi, When I try to install my codesys program with the new application-based licensing, I have an error "it exceeds the scope of the license agreement. See Device > Licensed Software Metrics" In the Licensed Software Metrics section, I see a code size < 3MB and less than 2700 variables in visualiaztions. I'm using a license "Control Basic L" with "Codesys Visualization L" option, so it should be enough with these metrics. What can I do ?

Post by hoatran on Use third party actuator with IO-Link Master (IFM) ^{CODESYS Forge talk (Post)}
The generic sensor FB is for controlling the sensor via its cyclic input (PDI) and output (PDO). In this case, ifm raw cyclic input and output data are WORDs (16 bits total) The PDO data from the Buerkert unit are SINT (8 bits) In this case, I would use the unpackword fb from the CAA memory library to unpack the valve feed back value into the appropriate location.

Post by dkugler on Alarm State Icon ^{CODESYS Forge talk (Post)}
thank you for pointing me to this "bug"!! I haven't recognized, the bit is reset after the first alarm is gone. I use this only for warnings, so it's not a drama, but was not correct in the past. I solved it now simply stupid by counting up a variable every time an alarm appears and decreasing it if an alarm is gone. The "warning lamp" is activated by checking the counter is > 0 The nice side effect, i'm able to show the number of active alarms in the state line now.

I bought and installed SoftMotion Light now. When I try to add a SoftMotion Light Axis to my stepper drive and I go online it shows: "The license is missing or invalid". See picture What am I doing wrong? This is the right way right? First add your EtherCat XML-File from your stepper driver and then add the SoftMotion Light axis right? Thanks for your help esave

there is a new problem with latest bootloader version. The problem seems to be: Version from2024-04-20 does not work-> 2024-01-15 version works the workaround is a rollback to January version: cp /lib/firmware/raspberrypi/bootloader-2712/stable/pieeprom-2024-01-15.bin ./pieeprom.bin rpi-eeprom-config pieeprom.bin > bootconf.txt rpi-eeprom-config --out pieeprom-new.bin --config bootconf.txt pieeprom.bin sudo rpi-eeprom-update -d -f ./pieeprom-new.bin sudo reboot

Post by alez on CANOpen SDO to write VISIBLE STRING ^{CODESYS Forge talk (Post)}
Hello, I am experiencing difficulties in configuring a CANopen device by sending SDOs. In particular I am attempting to write an Object Dictionary that has VISIBLE STRING as the Data Type. When I try to configure the sending of an SDO from Codesys to configure this parameter I am not allowed to enter a string value. In my particular case I am trying to change the Manufacturer Device Name ( Index 0x1008 ). Could it be that Codesys doesn't manage these types of variables?

Hi All Thanks for sharing this information. For whom may not know why always get error code 16#4000 or 16#4002 while performing Recipe commands, the root cause is There is a line need to be inserted in CODESYSControl.cfg file, which is PlaceholderFilePath.1=/var/opt/codesys/PlcLogic/ I am using Pi, therefore the above path is set to my pi unit, after adding above line to my cfg file, all the Recipe commands work fine. But I still do not know how and when this file got modified though.

Post by gseidel on Discontinuity of A/B/C axis movement. ^{CODESYS Forge talk (Post)}
Hi jonasz, you already solved it, I'm answering here for the sake of others with a similar question. You can provide the slope of the A/B/C axis with the U/V/W word. See example 3 here: https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_cnc_din66025_additional_axis.html If you don't want to change the G-Code, the function block SMC_RecomputeABCSlopes can compute the slopes automatically. https://content.helpme-codesys.com/en/libs/SM3_CNC/Current/SM_CNC_POUs/SoftMotion-CNC/SoftMotion-Function-Blocks/SMC_RecomputeABCSlopes.html Best regards, Georg

Post by gseidel on CNC - system goes to X=0 Y=0 before CNC file execution starts, how to avoid that? ^{CODESYS Forge talk (Post)}
Hi peterned, the start position given in the CNC properties is only used if you use the compile mode OutQueue. With compile mode SMC_CNC_REF, you need to provide the start position in the IEC application. The function block SMC_NCInterpreter has an input piStartPosition. You can initialize it with the output of the forward kinematic transormation FB for your machine. In your case probably SMC_TRAFOF_Gantry2. Best regards, Georg

Update: I started over. I saved progress at each step. all compiled zero errors, zero warnings. Pre-processor messages remain, but I can make progress. Until I try to re- load the project file in Codesys. Re-loaded files error as above when compiled, even though they compiled error-free immediately before saving. Is my installation borked? (Not easy to re-install due to IT madness...)

Post by yannickasselin on How to sort JSON object in codesys ^{CODESYS Forge talk (Post)}
Just adding: sSubscriberdata := ''; Right before your memcopy should fix the extra characters. It is because your are copying 36 characters into a string which can contain more than 36 characters and there is garbage left in the extra characters. Regarding the parsing of json, I usually build a structure that mirrors the json data and use the available methods in the IIoT library to parse the data and fill the structure.

I have been trying to set an array value to a JSON structure of this form: {"key": [1,2,3,4]} While I have been able to create the key and set its value to an empty array, I've not had any luck in putting any value in that array. objindex:= fb_JBuilder.SetKeyWithArray("Key6", diParentIndex := diRootIndex); objindex2:= fb_JBuilder.SetValue(value:= iValue2, diParentIndex:= objindex); iValue2: ARRAY[0..3] OF INT:= [1,2,3,4]; The two lines of code above produce {"key6": []} . The second line essentially has no effect.

Post by totorovic on Softmotion not working with simulation mode ^{CODESYS Forge talk (Post)}
Good morning, I think that the mode Simulation does not support the Softmotion functionnality because it runs the CODESYS process with normal priority wich is not a good thing for real-time behavior. If you want to test your PLC project, please use a Codesys Control Softmotion (and your computer must have the Ethercat driver installed) or much easier, download your code into the C6 Smart. BR
