Post by andre-luis on Device diagnosis ( EtherCAT IO card ) ^{CODESYS Forge talk (Post)}
Hi @TimvH, In the meantime, I did some experiments and could find a way to achieve similar result. I made some tests, removing the last card from the array, seeing the change on status. PROGRAM P_IOS_STATUSES VAR devStateInput : DEVICE_STATE; devStateOutput : DEVICE_STATE; devStateEncoder : DEVICE_STATE; END_VAR devStateInput := IoConfig_Globals.EL1819.GetDeviceState(); devStateOutput := IoConfig_Globals.EL2809.GetDeviceState(); devStateEncoder := IoConfig_Globals.EL5151.GetDeviceState(); GVL.bInputCardOK := ( devStateInput = DEVICE_STATE.RUNNING ); GVL.bOutputCardOK := ( devStateOutput = DEVICE_STATE.RUNNING ); GVL.bEncoderCardOK := ( devStateEncoder = DEVICE_STATE.RUNNING ); Many thanks for your quick and extensive reply.

Post by dogulas on Removing a symbol from the IEC Symbols Editor grid ^{CODESYS Forge talk (Post)}
Right now when I make a change to one of the tags in my code, I have to completely remove the IEC Symbol Publishing object from the tree view and re-add it. Then I have to completely re-add every symbol to the grid view by dragging them over. This can be a lot. Surely, this is not the intended behavior. Can anyone tell me how this is supposed to work?

Post by struccc on When running as a service, CodesysControl doesn't write log files to the disk (and other CmpLog related issuess) ^{CODESYS Forge talk (Post)}
Are you sure when running as service, it is not reading configuration from C:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS... ? Is the SRV user is set for the CODESYS services? 2 ways to fix it: Change the CODESYSControl.cfg in the installation directory (ProgramFiles/CODESYS...). Replace %APPDATA% with something fix. Modify the service configuration in windows service manager to run as a different user (ie bot as Local system account)

What is the task configuration? When you are online and look at the task monitor, what does it show? (Put a screenshot here). If the processor is overloaded you'll likely need to increase the cycle interval, disable the watchdog, or change to a cyclic task instead of interval based? Also, You might want to adjust your task priorities so they don't all have the same priority. Just a few thoughts, although looking at the task monitor would help in troubleshooting.

Post by pistola on How to change font and font color rectangle/or related object ^{CODESYS Forge talk (Post)}
Here is the help sections for visual elements rectangle. https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_elem_rectangle.html Under "Font Variable" there is "Color" which is a Dword, you can make a variable that changes colour within your code to the color needed. Note the format for the Dword variable is: colorVariable := 16#TTRRGGBB Where: TT = Transparency 00-FF RE = Red 00-FF GG = Green 00-FF BB = Blue 00-FF https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_animate_color.html

Post by atone on Set DeviceID of an IO-Link Sensor at Runtime ^{CODESYS Forge talk (Post)}
I need to be able to change (set) the DeviceID of an IO-Link sensor (see DeviceID.png) at runtime. I tried with both ProfinetCommon.PN_PortConfiguration and ProfinetCommon.IOL_PortConfiguration, but I get an error for both when I try to read the port configuration (see PN_PortConfiguration.png). Does one of those FBs is the right one for my purpose? Do I possibly make a mistake when assigning the parameter IOLD_ID/IOLM_ID?

i had a similar problem trying to send files to C: on local computer. Ended up using Oscat ftp to transfer file with filezilla. i read there is an "write protection", possibly to do with windows, issue with sp19 and up. there are some config files in the codesys dir you can change, which may help. after i was able to transfer to local PC\downloads but not c: so went the ftp route. works well. https://forge.codesys.com/forge/talk/Runtime/thread/5cac1390b4/

Post by berkdan on SMC_ReadNCFile2 is always busy ^{CODESYS Forge talk (Post)}
Hey tk96 Thank you for your help. I have found the reason why fbreader stuck. It was not the program but it was the gcode itself. G21 command blocks the reader. And multiple G codes in a line also blocks the reader. My code was: N010 G21 G17 G90 -> Blocked the reader When i change it to: N010 G90 N020 G17 Then it worked. The only thing i did not get is why the reader did not thwor error. ErrorId was SMC_NO_ERROR. Anyway, it is now working. Thanks again.

Post by timvh on How to change keyboard layout on the virtual keyboard? ^{CODESYS Forge talk (Post)}
Maybe you have the "Devices" tab open(?), but the "templates" are in the POU pool. You can open it from the menu: View - POUs, or if it is already open, select the POUs tab which is normally next to the Devices tab. All objects which are part of a library are in the POU pool, because they should be device independent (at least most of them).

Post by jinlee on Multiple WebVisu ^{CODESYS Forge talk (Post)}
Hi guys, I am new to the Visualization. I am having a problem. I have multiple web-panel to use webvisu. I have my software dowwloaded into the one PFC200. There are 3 screens connected to it. I noticed that if I switch page/visualisation on one of the screens, the others will change as well. Three screens are with different URLs that I set in the software. Is there any method to make them independently ? Kind regards, Jin.

Post by jaspergain on Access to the path *** is denied ^{CODESYS Forge talk (Post)}
Hello, Recently I upgraded to 3.5.19.50 and have been having errors/issues when doing a download/online change. The message as seen in the attachment pops up. The file in the path is different every time. However when I login again afterwards all works fine. This issue does not happen on older versions. Any clue what the issue could be? I did an reinstall/repair but the issue reappeared again... Thanks in advance!

Post by jinlee on Multiple WebVisu ^{CODESYS Forge talk (Post)}
Hi, thank you for replying. Basically, I have a main visu with frame selection. So, under some condition the frame will switch to a specific frame. It used to be controlled by variable using "Switch frame variable". However, I realise it will change all the HMI screen at one time. So I removed the variable, and still looking for a solution to do that. Do you have any idea?

Post by aniket-b on Multiple function blocks are not executing at the same time in ladder logic ^{CODESYS Forge talk (Post)}
I have two ethernet Ip drives and created Function Blocks for different motions tasks. I am using same FB for both the drives. When I try to execute the relative move start command on FB for both the drives it is not working. However, if I add 1ms second delay between the execution of each drive it is working. Also when I change the rung order it is working for the first drive in the rung. what could be the wrong here?

Post by timvh on Device logon problem following fresh install ^{CODESYS Forge talk (Post)}
In your project you selected the "CODESYS Control Win V3" as device, but the device you want to connect to is a "CODESYS Control Win V3 x64". Those are not the same. If you double click on the device during the network scan, you will get information that these are not the same, but that you can change the type in your project to the x64 bit type. Another option is to "right-click" on the device in the device tree of your project and select "update device" then select the x64 type.

Post by andy-yemm on Assertion Failed ^{CODESYS Forge talk (Post)}
I had similar assertion failed error messages today. I am fairly new to Codesys. I tried using SFC for the first time, I usually use ST. Anyway I had errors in some of my transitions. I copied and pasted transition code and forgot to change the target of the code. I started getting lots of the assertion errors but now I have sorted out the problems and it compiles OK the assertion error messages seem to have stopped. There do not seem to be any other responses to your post, did you resolve your problem?

Post by marcolim on RPC failed 0x16c9a085 ^{CODESYS Forge talk (Post)}
Hello Matteo, I think the problem is about configuration of firewall (windows firewall usually). You can disable temporary the firewall to check if the communication works. Eventually you can: Go to the control panel -> Windows Defender Firewall -> Allow an app or feature Enable the options to change the settings. Scroll down in the application list to CODESYS and CODESYS ControlService. If you don’t see this application add it to the list. Make sure that all the checkboxes are checked (Domain, Private and public).

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?

Post by timvh on JSON ^{CODESYS Forge talk (Post)}
I don't know the details of jsonArrayWriter, but the common behaviour for an xExecute input is that the FB starts on the trigger that it gets TRUE. In your case xExecute is never FALSE, so it is never triggered again to start the jsonArrayWriter. So change the condition from TRUE to a variable which you set to TRUE with the "xFirst". Then when the jsonArrayWriter is done (xDone), or has an error (xError), then set this variable to FALSE.

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 ph0010421 on General question about library versions ^{CODESYS Forge talk (Post)}
Hello I can't find anything to read on the subject so I'll ask here. Up to now, when adding a (for example) Modbus Master, I've selected the version <= the RT version, so if I'm using SP13 Patch 3, I can use a library that doesn't exceed this. I've no idea if this is correct, but it's always worked. Can someone explain the 4.x.x.x libraries that have appeared; are they tied to a RT version? The controller I use is now at SP18Patch60, so should I continue to use 3.5.xxx or change? thanks

Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
All Sensors from the OneWire Master are assigned already to a seperate task with low prio (26) that runs with 1s cycle time. My EtherCat Task is running with Prio 1. It all works fine, until I adjust the CODESYScontrol.cfg or the CODESYScontrol_Usr.cfg files so that it supports a 2nd OneWire Master in the Codeys Runtime. If I change something in this config file and reboot my EtherCat Master stops working.
