Post by sunfloweeerrry on Edgelogix-rpi-1000-cm4102032 SPI port connection to PiFace I/O Driver in CodeSys. ^{CODESYS Forge talk (Post)}
Hello, I hv a problem. Couldn't solve this for 2 days now. So I'm quite new at CodeSys and I have to use the spi port x30 on the edgelogix rpi 1000. So what I have to do is just 'add device' at the SPI where I hv to pick the 'SPI master' after that I hv to change the parameters according to the edgelogix I did found in the spidev.h but nothing got updated so I 'add device' again where I pick the PiFace I/O Driver and I put my variables at the I/O Mapping, which i put the input startbit at the in part and led at the out part. I want to make the led blink according to my structured text code but somehow the hardware didn't connected with the CodeSys spi port. Nothing happens. Any idea what I have to do?

Post by ofey on Codesys Soft PLC OPC UA server ^{CODESYS Forge talk (Post)}
Hi! I'm sorry if this has been asked before. I have tried looking up previous topics regaring this, but even though I'm following tutorials and other posts I cant seem to get this to work consistently. I actually got the connection established on a test project after some trial and error. I only got it to work with the "Anonymous login". But after i deleted the test project and tried to get the same thing to work on another project I cant get it to work anymore. What I'm trying to do: Set up and OPC UA Server using CODESYS with the free soft PLC. I then try to connect to the OPC UA Server with the program "UaExpert". What happens: I get the error Error "'BadUserAccessDenied' was returned during ActivateSession". What I have done in CODESYS: - Added the object "Symbol configuration" and checked some test variables - Checked "Support OPC UA features - In "Communication settings -> device -> Change runtime security policy" I have checked "Allow anonymous login" What I have done in UAExpert: - Found the OPC UA server under "local". (It is showing two servers though, I do not know why. It showed the same when it worked yesterday). Se attachment - Checked "Anonymous" under "Authentication settings in the OPC UA server. I'm new to CODESYS, so it could be something elementary wrong in my settings. Maybe something in the user settings in CODESYS regarding user rights or something?

Post by sturmghost on Initialization of visualization variables and cyclic code execution ^{CODESYS Forge talk (Post)}
I'm looking for a smart and short way to implement initialization of visualization variables depending on the visualization input. For an easy example consider a rectangle which rests at XPos := 0 when the input state is false and at XPos := 50 when the input state is true. My visualization variables look like this: VAR_IN_OUT State : BOOL; END_VAR VAR XPos : INT; END_VAR I put this rectangle via a visualization frame element into another visualization and link a frame reference variable with the state to it. If the variable is true, the rectangle should rest at XPos := 50 and false at XPos := 0 at visualization init but how should I assign the 50 or 0 to the internal visualization variable XPos? I would need some init-methode for the visualization but I dont want a global init-method for such tasks. I want to do it inside of the visualization element but I can't see any solution for this? It would be good to be able to define ST-code within the visualization element which runs cyclic at each VISU_TASK task-cycle then I could just check the input state and change the XPos accordingly. Does someone have a solution?

Post by captaincookie on increase default string length in queue ^{CODESYS Forge talk (Post)}
Hello, I'm using Codesys V3.5 SP18 Patch 4. In the ElementCollectionExample Project from Codesys, I test the SimpleQueueExample in a Control Win V3 x64 environment. I try to add a string of 95 characters length to a queue. The default length of strings is defined as 80 characters. In the initialization of a string variable, it is possible to increase the length by the definition of e.g. STRING(1000). But when I write the string defined like this to the queue, only 80 characters are written to it and the rest is missing. I think the default length is still set in the queue definition, so it is necessary to change this, isn't it? Is there any option to increase the default length of strings in the queue? Attached you can find the used project. Thanks in advance. If any information are missing or my description unclear please let me know.

Post by manuknecht on Persistence Manager does not save alphabetically first value ^{CODESYS Forge talk (Post)}
After some more digging I realized that I get an error on the PLC Logger saying PersistenceChannel: 150 (invalid type in data: SimpleLibrary). I suppose the issue could be found in the ConfigData, which is automatically generated and which looks like this: 1 9##83 SimpleLibrary#GVL.aMoreZeros.[1]#0#64512#15#0 <[2]#0#64520#15#0 <[3]#0#64528#15#0 <[4]#0#64536#15#0 <#0#64544#15#0 <[6]#0#64552#15#0 <<lrVar#0#64560#15#0 <strVar#0#64428#16#80 <uiDummy#0#64370#11#0 Perhaps the fact that the variable is stored within a library confused the compiler? I tried changing the PersistenceChannel parameters to xCompressTags := FALSE which changed the entry in the data file from _xCompressTags BOOL:TRUE _xCompressTags BOOL:FALSE but the actual content of the data file and also the config data did not change.

Post by ewi04 on Git with visu ^{CODESYS Forge talk (Post)}
Hi, I have several problems with the git extension. Situation: I am working with Codesys v3.5 SP19 Patch 1 and Git V1.2.1.0. The remote repository is GitLab Community Edition v16.1.2. I am working on a project with one other person. Problems: 1: After each start of Codesys all of the visu pages are marked as modified. So we have to discard all changes first. Otherwise the history is not clean and the merge request becomes more complex. I tested it with a new project and only local. I made the observation, that a page is not marked as modified when it is committed a second time (after a restart of codesys). But this is necessary after every change of a page. However, since we are working in a team, it seems we are playing ping-pong and so all pages are marked as modified on each startup. 2: Each image pool causes a parent child conflict. Also in my local project. The only solution that I have found, is to ignore the issue. Does anyone have the same problems? I think it looks more like bugs. Thanks ewi04

Post by sturmghost on Mimic behavior of the visualization button element with a custom button ^{CODESYS Forge talk (Post)}
Im wondering how Codesys is doing the mouse event capturing with their visualization button element? If you add such a button without configuring any input configuration event (like OnMouseDown) or button state variable and then click on the button, the button changes to the visual pressed state and back if you release the button (so they must react to an OnMouseDown event). But how? If I try to mimic this behavior with my custom button visualization element (like a basic rectangle) I need to use an input configuration event to change the color of the button (to make it look like the button was pressed on OnMouseDown event). When I try to add this button via a Frame-Element to my main visualization page I'm unable to use an input configuration event on the Frame-Element because the input configuration event on the button element won't be evaluated anymore (it seems like you can't stack input fields, e.g. invisible input elements, onto each other). Hence the button is not shown pressed anymore. How they do it?

Post by paulorb on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
Hi I am trying to use STRUCT to parse commands from Modbus/TCP, Modbus client will fill the bytes related to a specific command (type, parameters), then PLC (Codesys) will access the command parameters. A STRUCT will simplify a lot the process of parsing the data, so I don't need to parse byte per byte, address will be mapped to a struct and I can use it for parsing the data. From what I understood, the compiler does not allow me to specify the location of the struct for a %MW register. VAR_COMMAND AT %MW1002: structGenericModbusCommand; This will throw: Bad declaration, use '%ML' for 'structGenericModbusCommand' variable But If I change it to %ML, when you go online you see that it is actually allocating the struct in another memory address. When we go online, on GVL we can see: VAR_COMMAND. structGenericModbusCommand %ML1002 commandType COMMANDTYPE %MB8016 ... %MB8020 I am not specifying a pointer or a reference it is a struct type, why is it mapping to a %MW location (random one). How can I control where it is mapping to? I need a consistent way to map STRUCT to specific modbus address. Is it possible? Thanks, Paulo Note I am using a Codesys OEM: Schneider Machine Expert Logic Builder (M241)

Post by mainak on Opaque NodeId in the OPC UA server ^{CODESYS Forge talk (Post)}
Hello all, I am using the OPC UA server with my custom information model. I have used the communication manager to add my information model under my application and created instances from OPC UA types. I see that the created instances in the OPC UA server has some opaque nodeid (attached screenshot) and I want to change that. Therefore I have the following questions: 1. Is there a way to configure the NodeIds of instances in the OPC UA server? I tried to edit it using the UaExpert client but got error "BadNotWriteable". is it possible to configure it somewhere so that the nodeids can be changed using an external client? 2. Is there a way to define the rule for creating instance nodeids within the codesys IDE? 3. Is it possible to create the instances before e.g. using a modelling tool like UaModeler and import them as part of the information model and use them later? Using the communication manager, I can only create instances from types. I couldn't find a way to map my existing instances to plc tags from my application. It would be nice if someone could help me with these issues. Thanks in advance. :)

Post by fabiodasilveira on PLC Shell commands via ST Code ^{CODESYS Forge talk (Post)}
Hello Everybody, I have created a project for an Eaton XC303 that sends lots of data to a router via UDP. It works fine. However, when there is more than one product connected to the router, then it is necessary to change the IP address of the Ethernet port 0, from e.g. 192.168.2.11 to 192.168.2.12 (second product). It is easily done via PLC Shell (setipaddr 0 192.168.2.12), but the people in production is struggling with the PLC Shell commands and I would like to create a Visualization page that will hide that. I used the instruction: eChangeIPResult:= SysSockSetIPAddress(strEthernetPort, strIPAddress); and it works, until the PLC resets. I already read some posts and it appears that I need to stop the Ethernet 0 port and Reconfigure it, but I am really struggling to find the right way to do it. Any help will be much appreciated.

Post by pernockham on Pointer/reference to Codesys trend recording object? ^{CODESYS Forge talk (Post)}
I have a Hmi that acts as an interface for many (mostly identical) units. This is managed by a sort of "mux" where you select which unit that should be presented on the HMI. Backbone is solved by a HMI-gvl defined as reference/pointer to "unit-data", which then can be set to the individual units. While this works for most data I still have not sorted how to solve this for the trend recordings. One solution would be to have already "mux:ed" data values as source for the/one trend. However then the trend would contain data from different units/sources which could/will cause confusion. If its possible to "clear" this can be mitigated. Possibly let the trend have its own "mux-selector" (ie, the hmi are focusing on unit#3 however trend data is locked on unit#5), that could also work.. Or, let each unit have its own trend recording, which is focused if the unit is "selected". Can I reach the trend recording objects programmatically (those defined in the device tree)? Ie, can I use a "reference/pointer to these trend recording objects"? There is a field "data source" in the trend properties dialog which seems to resemble what Im looking for? But Im not sure if I can use it in some way, I cannot change anything in this field it only says <local application="">. </local>

Post by wbj0t on mobus tcp slave device. read/write holdings with 2 variables. ^{CODESYS Forge talk (Post)}
Hi there. I have an issue to read and set time for the controller. In the issue many registers described as writable by 6/16 functions, and, in this time, also(!) readable! For example: I have time registers: min, hour, day, mon, year. By specifications it is possible check time (so I need always update these varibles in loop) and set time by writing these same registers, BUT how to set, if they will immediatle updated by current time after writing? So, I need to separate one address at two variables. I have seen option mark: Overlay of the process image by the holding and input register. I understand this so: When I READ by function 3, I will get variable that connected with the same INPUT address and when I WRITE by 6/16 this will change second variable that connected with HOLDING address. BUT, this mark doesnt work, when I write 6/16 and try to get by function 3, I will get written value instead INPUT variable. So, what to do?

Hi Duvan, You could make this in 1 single object (FB), Indeed don't use a function for this beacuse you need some memory to keep the old value. For i := 0 TO 200 BY 1 DO //Check if the value has been changed IF Old_Value[i] <> Value[i] THEN //Set the trigger to TRUE Trigger[i] := TRUE; Old_Value[i] := Value[i]; END_IF END_FOR If you define the Value array as an In_Out and the Trigger as an In_Out you arn't claiming any aditional memory to your system. You ofcourse then need to add some code arround it that does something with the trigger and writes it back to FALSE again. If you want more flexability you also could use pointers instead of using the IN_OUT FOR i := 0 TO 200 BY 1 DO address := address_Input + i * SIZEOF(*Put type here); IF Address^ <> Old_Value[i] THEN Trigger[i] := TRUE; Old_Value[i] := Address^; END_IF END_FOR

Hi everyone; I'm building a project in which the drag of the mouse over some controls (or the click event) changes the background color of the control items; this change of color is made with an FB that assignes a color code to the background with MUX command based on the value of an enumerator, this part is perfectly working but, when I'm using a touchpanel instead of a web visu (controlled by a mouse) I get into some issues as it seems that the touch operations are not triggering the MouseEnter and MouseLeave properties as it's done with the mouse.... For this reason I'm trying to add a TON to my FB and, if the enum that changes color remains at the same state for more then 3s I'm automatically resetting it to it's "0" so the item gets back the not selected color. Anyhow it looks like the TON function from library is not working in these FB that are instanced in the various visualizations, as instead they do if I create some instances within the POUS. Anyone has ideas of how to make them work?

Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge talk (Post)}
Hello mates, I'm working with CODESYS V3.5 SP20 on a Raspberry Pi and I use "Raspberry Pi MC SL" as device on the project. I've installed the Control Standard L (multicore) license on a Wibu System usb-Dongle (cmStick/4.50) that already had another license from another vendor. I follow the online activation procedure from CODESYS documentation. Raspberry Pi has already CodeMeter installed for the other license. When I plugin the dongle on Raspberry and start the Runtime from Raspberry Pi Update in CODESYS I receive the message that I'm on Demo mode because the license is missing. I double checked that the license is activated in the dongle, through the WebAdmin of CodeMeter and the second license runs properly without any issue. I have already try to change the dongle from HID to MSD device and backward but the the Runtime cannot recognize the Dongle. I have also try to stop and start the Runtime through CODESYS without success. Is there anything else I can do to fix this issue?

So the idee by 3s has a flod. Epis change the system to add the Stick. I send controller inc stick to Epis. On my software i can see the stick. An then you tel me i need a other license to use an license ?? Makes completly no sense. Codesys should be flexible but is not. I tried Delta. But has no HMI and has its own Codesys ?? Why ?? Then i tried Crist. The block there own system by a password. But dont know the password and cant switch it off. At the end the want me to pay for support to solve ther own made problem. So i send it al back. The extra license is adviced by 3s . Now a few month later still no working solution.

I have a Raspberry Pi 4 we have been using for years to run CODESYS for development purposes. I recently have had to re-install the OS (Raspberry OS lite). The only change to the default configuration is not creating the "pi" user during install. I (apparently successfully) installed the 4.10.0.0 control on the Raspberry Pi. We have licences on a dongle. I am able to start the control. systemctl status shows it as running for a little while (exactly, precisely 30 seconds as per my tests, every time), then it becomes exited. I can restart the control, and the same thing happens again. Every time. In the brief moments it is running, I can log in to the PLC. Working fast and restarting the control many times, I have been able to configure users. I have been able to download my application. I have been able to run the application, and stop on a breakpoint. I have been able to connect with the licence manager and confirm the dongle is detected and licences are listed as OK. I see nothing wrong until the service just exits. I have found nothing in the logs. It is like the runtime just terminates with no error code or message after exactly 30 seconds. Any help would be appreciated.

Hello everyone, I am new to this forum and I am also new to Codesys programming. My problem is this: I have a STRUCT of 64 bool and 30 real, this STRUCT is assigned in the programme 9 times. Now I need to communicate with an HMI via Modbus and I have defined the slave device and created the holding registers for communication. I would like to declare the first call of the STRUCT on the Modbus registers %QX2000.0 to %QX2007.7 for the booleans and on the registers %QW1004 to %QW1034 for the real registers. That said, I would like to change an index and set an offset of 100 bytes for the calls of the other 8 assignments, so that the result is: %QX2100.0 to %QX2107.7 for the booleans and on the %QW1104 to %QW1134 registers for the Real registers, etc. Is there a way to declare this? Thank you very much.

I created some requests of type ModbusRequest and I notice that I can read Input Registers and Coils but I can not write Holding Registers and Coils. I am using the library IoDrvModbusTCP 4.1.0.0. When i just use a single modbus request with FC06 (or FC16), there is no request sent to the slave and although the xExecute takes its true value from a pulse of 2 seconds duration, I take almost every 3 minutes an error "TCP_COMMUNICATION_ERROR - 16#A5 - TCP Port. error. Request was not sent". My code is ok because if i change the function code for reading registers, everything works fine. Did anyone have this issue in the past? Thank you in advance.

Post by manuknecht on XY Chart causes extremely long cycle in Visu Task ^{CODESYS Forge talk (Post)}
I am using the visualization element "Cartesian XY Chart" in a visualization template within a library to display recorded position values. I managed to configure the chart as desired and it displays the values like it should. A problem occurs when clicking on the chart to move the cursor, zoom or pan. Upon clicking the visualization element for the first time, the task in which the visualization is run spikes to a cycle time of around 5'000 to 15'000 ms (the configured cycle time is 100 ms). Sometimes this even completely crashes the web-visualization. After this very long cycle, the visu task normalizes again and the chart can be interacted with as usual. Another spike in cycle time occurs once the visualization is switched to a frame that does not contain the chart. I did reduce the data array to only a few values and tried changing the update behaviour of the chart, but it did not change the problems I am facing. Did anyone experience a similar issue or even has a solution for this?

Post by risele on Modbus connection via Qronox PCD3 M6893 ^{CODESYS Forge talk (Post)}
First, if you don't need to change conversion rules in runtime, take a look at "Unit conversion" module (Application -> add object -> UnitConversion). You can specify there biderectional conversion with different units, limits and so on. Second, since MODBUS don't have "real" types but only general 16-bit registers and Real is 32-bit, generally you need a byte-was conversion Real <> two Words. Note, that depending on the devices on both sides, there are two options: Real-> Word1, Word2 or Real-> Word2, Word1, where Word1 is minor register in Modbus register pair and Word2 is major. You can use simple union: TYPE u_Real : UNION rVal:REAL; wVal:ARRAY[0..1] OF WORD; dwVAL:DWORD; //same as previous, may be easier to specify the MB register END_UNION END_TYPE and convert it as following: VAR myUnion:u_Real; rValue_TO_SEND:REAL; rValue_TO_GET:REAL; END_VAR myUnion.rVal:=rValue_TO_SEND; rValue_TO_GET:=myUnion.rVal; Note, that WORD-order should be properly set in MODBUS registers, otherwise you will get strange values. This tool is helpful: https://www.scadacore.com/tools/programming-calculators/online-hex-converter/ Alternative, you can use functions as REAL_TO_DW and DW_TO_REAL from OSCAT_BASIC, for example.
