Post by macros8 on Translation - How to get text as reference in Frames translated? ^{CODESYS Forge talk (Post)}
Hi, thanks for the link. Maybe I create elements in incorrect way. I always use Interface Editor to create variables which are used inside element (see pics). After that I place element in my visu and use Reference property to link variable or set the value. In that case the value of string is not transferred to general text list for translation as I mentioned before. Do I have to all properties which influence behavior of my element create in Frame configuration instead? What´s the difference to the Interface editor? Thanks a lot. M.

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.

Post by jmohre on External file with relative path ^{CODESYS Forge talk (Post)}
I try to add a simple text file to my PLC application, so that is download everytime the application is downloaded to the target. What I did is to add an external file to the application and this works perfect as long as the external file location does not change. It looks like the external file path is stored absolute in project. But if different users work on the project they may have different locations where for their working directory. Is there an option to store the external file path relative e.g. to the project file? Or does s.o. know a different solution to add a text file to application in order to download automatically with the application? Thanks

Post by idalu on Profinet PN_Controller Issue, Network Adapter ^{CODESYS Forge talk (Post)}
i have a problem with Profinet on my project. I'm using Codesys RTE 3.5.19.50. When i download program to controller the ethernet is ok, PN_Controller is ok but every device i'm trying to connect is red with error "DCP no RealStationName". When i'm trying to Scan for Devices on PN_Controller there are no devices found. I have installed Codesys driver CmpEt1000Drv to my network adapter (i'm sure it is right intel pro 1000 model). I have noticed that when i installed codesys driver i'm no longer able to ping this network adapter (i can ping it when intel driver is installed). On my previous projects with runetimes i can ping it even with codesys driver installed. I have also tried to do downgrade of everything to version 3.5.19.20 and it not helped.

Post by matt-s on HMI Pushbutton/Move Instruction ^{CODESYS Forge talk (Post)}
I am having an issue where the manual start/stop push buttons on the HMI are supposed to take the pumps/blowers out of auto. The logic I have attached works for the pumps, but not the blower. From what I can tell it is the exact same logic, but it is not writing a 0 to the Auto PB variable. Attached is the logic, cross reference list to show nothing else is writing to it, and the HMI screen. Any help? Am I missing something? I am using a Groov Epic PR1, my software version is 3.5 SP19 Patch 5 32 Bit.

Try using an Ethernet/IP scanner instead of an adapter, I'm guessing the 2 devices you're trying to communicate with are adapters, you have to have a scanner somewhere and Codesys should be a scanner. I don't know why you're getting the error, you should be able to use your Ethernet port as an EthernetIP adapter (although I've never had a reason to try,) but it's probably not what you wanted to do, unless you're connecting to another PLC that is a scanner. Good luck configuring the devices you're trying to connect to, it will be a lot easier if you have an .EDS file instead of starting with a generic module, even with an .EDS it can be tricky getting the communication working.

Post by alexgooi on Update boot project default unchecked ^{CODESYS Forge talk (Post)}
Dear Forum, I'm currently switching to Codesys V3.5 SP19. When I want to do an online change, I get the option to update the boot project, in other (codesys based) packages this is checked on by default. In Codesys V3.5 SP19 (and maybe older versions) this is unchecked by default. We are doing a lot of remote updates with systems that almost never power cycle. In other words when this box is forgotten the system will run fine until a blackout. Is it possible to get it checked on by default? This question was asked before, but no answers where given. https://forge.codesys.com/forge/talk/Engineering/thread/ffb4ffa298/ Thank you in advance.

Hello all, I am extremely new to Codesys and to programming with these languages in general. I have an HMI panel with 8 physical buttons to the right side of it. I am trying to have these set to change the visualization to a specific screen which I have designed 8 of. I currently have "use CurrentVisu" enabled in the visualization manager. I also have input blocks with all of the buttons being directed to output blocks which I want to have as the switcher for the visualization. Picture is attached for what I have currently. This could be the wrong approach to this issue. Any help is much appreciated.

Post by alexgooi on Codesys licensing explanation ^{CODESYS Forge talk (Post)}
Dear Forum, We are currently switching to a native Codesys controller, and I'm currently trying to determine the correct license. I have a question regarding the Modbus instances. With the Standard S license this is set to 4 (See picture). In our projects we are using a lot of communications to Modbus servers using a Codesys Controller, for this communication I'm using the ModbusFB library (supplied by 3S) (see picture). In my project I would like to use more than 4 instances of the ClientTCP FB. My question is, is this now capped at 4 possible connections with the standard S license. Or do these function blocks have a different relation with the license? Some clarity on this topic would be very welcome. Thank you in advance

Post by amy123 on codesys mqtt publish serialization ^{CODESYS Forge talk (Post)}
Hello, I am using the CODESYS IIoT Libraries SL MQTT Publish. Does this publish block only support publishing STRINGS as a readable format? I can publish ENUM, STRUCT, BOOL; however, MQTT Explorer will only display strings. When I use Wireshark, I can see that it is publishing something, but it looks to be publishing a serialized version which is a bunch of 0s or random text. If so, is there any way to deserialize this information back into a readable format? See pictures, where I have a BOOL TRUE that gets published as 001. Then see where I publish a STRUCT and it's an incomprehensible combination of 0s - only the string variable is displayed. Or, is it expected that you convert everything to a string before publishing? Any help is greatly appreciated! :)

Would also like to add them in the Ladder Toolbox as there are only 9 items in there which does not include the one mentioned above. Due because of the version I am using ? Any assistance would definitely be appreciated. Thank you Mike

Post by superjojo2002 on Licensing info not available. ^{CODESYS Forge talk (Post)}
If support for a containerized CODESYS runtime with a license isn't feasible, then I've considered an alternative approach: I've purchased and activated a "CODESYS Control Basic S" license on my Windows notebook, where I already have the Codemeter Control Center installed. Upon activation, I can see the CODESYS license as active on my notebook. Subsequently, I followed the instructions provided in this link (https://faq.codesys.com/display/CDSFAQ/How+to%3A+Setup+a+Wibu+Network+Server+Access+for+Licenses) to configure the Wibu runtime in the CODESYS container to access my external license server hosted on my notebook by editing the CODESYSControl_User.cfg file accordingly. However, it's worth noting that I'm still receiving a response from the Licensing Manager indicating that the runtime is persistently searching for a dongle instead of recognizing the soft container. So how can I get my runtime licensed now? Any ideas?

Post by phoward131 on Text List Fallback Value ^{CODESYS Forge talk (Post)}
I am relatively new to Codesys and I'm trying to develop an HMI that displays what mode a particular device is in based on an integer value. I am currently using dynamic texts with a text list which works fine but I am looking for a way to display a particular string (ie 'Unknown') when the index doesn't match any of of the indices in the text list. I can enter 'Unknown' in the text property of the text field element which works as expected but it displays the single quotes on the visualization. How can I escape these quotes to simply display the word Unknown? Thanks!

Post by struccc on Release SP20 - Changes in behaviour? ^{CODESYS Forge talk (Post)}
Dear all, I've just started to migrate some of my ancient projects to SP20. There is one strange error (?) I have noticed so far. In a method call, depending on the circumstances I would like to return reference to an object, or an invalid reference: METHOD Add_EVT_OUT : REFERENCE TO FB_MSG VAR END_VAR IF __ISVALIDREF(refMSG_Entry) THEN Add_EVT_OUT REF= MANAGER.AddMsg_EVT_OUT( refMSG_Entry, _Get_EVT_Message(MSG_EVENT.OUT), _Get_EVT_AddCode(MSG_EVENT.OUT) )^; ELSE Add_EVT_OUT := 0; END_IF So far setting a reference variable to 0, did this. But now, the expression Add_EVT_OUT := 0; gives an error: [ERROR] DB_WTP_370: Add_EVT_ACK MSG_TRIGGER_EXT: C0032: Cannot convert type 'BIT' to type 'REFERENCE TO FB_MSG' Naturally... I can write: Add_EVT_OUT := DWORD#0; But is this the correct way? Is there any constant I could use instead, like "NULL"? Or this is totally wrong and to be avoided?

Post by struccc on Release SP20 - Changes in behaviour? ^{CODESYS Forge talk (Post)}
This... is not very practical for me - as I have a bunch of different classes - it's just doesn't seems to be very practical to define a NULL for each of them... Something like this I use in parameter definitions. For example: VAR_INPUT refVFD_Drive : REFERENCE TO FB_VFD_Drive := GVL_DUMMY.Dummy_VFD; END_VAR I use this to prepare objects for code I don't control: Typycally visualizations - had many troubles with references set on the fly, right before opening a corresponding visualization... And yes, the instance in GVL_Dummy reports itself as "Fake", so it does not influence the actual application at all. Actually this way I could invalidate a reference, just to set it to a "Dummy" instance.

Post by alexgooi on Modbus writing on value change ^{CODESYS Forge talk (Post)}
The way I usally tackle this is by syncing only words (then you are able to use the FB above). If you then want to write a Boolean simply type it like this. Value[1].0 := Bool1; Value[1].1 := Bool2; Value[1].2 := Bool3; Uints have the same number of bits than a INT/WORD so these ones will work as well (they are only represented diffrently). A Real will work but you will loose some infomration in the conversion. If you want to keep the information you can convert 2 words to a float with a function (for example with the IEEE-754 standard) . In this way the syncing to the server is very simple and in the Codesys Program you decide what part of the word you want to use.

Looking to access a variable at runtime that indicates a user is online to the code. essentially want to use this value to feedback to the user on the HMI. we use turck and bosch rexroth devices if this information helps. I was hoping there was a variable at the application level, or a library that could be used but I was unable to find anything. I know there's a pop up when you try to login/ go online to the code when a user is already logged in, so the system does provide an indication that it knows already online, but has no access to a value from what I can see. Any help is appreciated

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?

Hi k2saki, I would recommend to have a look at SMC_SmoothMerge, followed by SMC_SmoothPath. SmoothMerge will combine the small G1 elements to longer splines, SmoothPath will avoid stops between the splines. https://content.helpme-codesys.com/en/libs/SM3_CNC/Current/SM_CNC_POUs/SoftMotion-CNC/SoftMotion-Function-Blocks/SMC_SmoothMerge.html For SmoothMerge to work, you have to configure a tolerance, i.e. by how much it may deviate from the lines. To graph the output of the interpolator, you can use the trace. (Add a trace object below the application, and add the variables you are interested in to the trace.) Best regards, Georg
