Post by gilbertamine on Comparing Arrays of structure ^{CODESYS Forge talk (Post)}
Hi Everybody, I'm looking for a simple way of comparing two array of a structure. My structure is define like this : TYPE Positions_T : STRUCT PosX: DINT; PosY: DINT; PosZ: DINT; END_STRUCT END_TYPE I have multiples Var : ARRAY [0..220] OF Positions_T, that I need to compare quickly. I don't really want to do a Loop that goes by every 220 points and compare each one of them so I was wondering if there is another way. I came accross the MEM.Compare function, but it require to know the size in Bytes of the memory, and I don't know how to do that... Has anybody an idea on how to do the comparing easily ? Thanks in advance

Post by jari-koivuluoma on Newly created texlists wont appear in the selection dropdown ^{CODESYS Forge talk (Post)}
When I create a new textlist in Codesys 3.5 SP19 Patch 5, it wont appear in the dropdown menu at Rectangle element > Dynamic texts > Text list. If I just type the name of the textlist to the field (in quotes), I get an error saying that some file is missing. Any good ideas what to do and what is going on. I recently updated to that version and I only now noticed this when I needed to add a new textlist so Im quite screwed with this not being able to add text lists. While im typing this, I tried copying an existing list and modifying it and it seems to show. Any ideas?

Post by hardcoder on EtherCAT Mailbox Gateway ^{CODESYS Forge talk (Post)}
Hi all I found that in the last Ethercat master release (4.8.0.0) the Mailbox Gateway feature has been added. This would be useful for me to connect to a specific slave in my system, since its configuration software supports this type of gateway communication. Anyway I don't find usage information or examples. At the moment I tried to enable it in the ethercat master device settings and I configured with an IP address on the subnet of the ethercat adapter (i.e. ethercat nic configured with static ip 192.168.10.100 subnet 255.255.255.0, mailbox gateway configured to 192.168.10.30). I expected it would have responded to ping commands on the address but nothing happens. I am missing something?

Post by gseidel on Beckhoff AS1060 and EL7041 configuration ^{CODESYS Forge talk (Post)}
Hi pmanuele, while I don't have firsthand experience with the EL7041 and the step motor AS1060, there are two things you can check: If you use an external encoder, please make sure you use the alternative device description calles "EL7041 1Ch. Stepper motor output stage (50V, 5A) Rev24 with external Encoder". The SoftMotion driver will set the feedback type automatically, and use the correct object for the actual position (16#6010:21 instead of 16#6010:20) If you have problems with changing the controller mode, I assume to velocity, please make sure you change the PDO mapping so that the actual velocity (16#6020:33) and set velocity (16#7010:33) are mapped by PDO. Hope this helps, Georg

Post by pernockham on Slider instance value when accessed through "execute ST-code" ^{CODESYS Forge talk (Post)}
I have a time which I want to modify with a slider. I have confirmed it is possible to set the value of the slider by to_real(time) (I can see that the slider changes according to 'my_time_value's value). Slider variable: to_real(my_time_value); However I fail to access the current slider instance value when I want to write back the value as time (write to a variable will not work as I need a type-conversion before assignment). my_time_value := to_time(slider-instance-value); I tried with this^.? but could not see anything interesting and also THIS^.GEN_Instance.? but nothing resemble what could be the sliders value. Anyone that knows? Thanks!

Hello, I try to add one of my PLC from the Gateways to the List view. The Gateway is shown me as online, also i have other remote tools to verify the Internet connection is working. I do the Network Scan and the Gateway shows up, i select it and click on "Add to Server". Then I type in Username and password and click on confirm. There it shows me the "Unkown Error", see screenshot. If I use the wrong credentials it gives me the error message for this. Other Devices work fine it's just this one. Greetings Jannis

Post by agentcousto on [Bug report] Issue with Importing XML Files Containing "POINTER TO" Variables in Codesys Platform Plugins Versions 2.7 and 2.8 ^{CODESYS Forge talk (Post)}
Hello, I have developed a Python script that I run to import XML files into my project. For this, I use the Python function import_xml(). Everything was working fine when I was using Codesys platform plugins version 2.6.1.2320, but since I upgraded to versions 2.7 and even 2.8, some files are no longer imported correctly. After some research, I identified that all the files containing variables of the type "POINTER TO" are affected. I have attached a screenshot of the error I am encountering. Do you know about this bug? Do you plan to fix it?

Bonjour Davidmic, Il n'est pas possible d'associer une méthode à une fonction. Cela est possible sur les Blocs fonctions.

Une autre idée, est d'utiliser les pointeurs ou les références. Bon développement!

I have updated CODESYS development tool to the version v3.5 SP21 (64bit) The previous version was v3.5.20.40 Compiling an existing application with the new evelopment tool I get the following error. kunbusiodrvrevpibridge, 1.4.1.0 (kunbus gmbh): IoDrvScanModules [IoDrvRevPiBridge](Line 51, Column 1 (Impl)): Internal Error (ARM): Unsupported conversion! This error was not reported in the previous compiler version and is now highlighted in a third-party library, which I cannot change or modify. The error is due to the following conversion: m_udiError := TO_UDINT(excCode); . The excCode variable is a system type, declared as shown below, and should be converted to a UDINT excCode : __SYSTEM.ExceptionCode; m_udiError: UDINT; . I would appreciate it if someone could provide feedback on this issue.

Hi Leute , ich bin neu hier im Forum und habe seit kurzer Zeit mein eigenes SPS-Projekt. Ich stoße hin und wieder an Probleme aber habe diese auf kurz oder lang gelöst. Nun zu meinem Problem: Als Projekt habe ich eine Kühlwassersteuerung , die einen Relativdruck einließst, und anhand desssen Werte dann einen Frequenzumrichter ansteuert. Z. Bsp. 5Bar -> FU auf 70Prozent. Ich lese in Codesys den Analogwert mit der Wago A20_750_455_020 ein. Dieser Wert wird umgerechnet mit LIN_TRAFO in 0-10 (Bar)und und wird dann über einen PID Regler geregelt. (Bibliothek UTIL). Dieser Wert wird dann wieder für die Ausgangskarte Umgerechnet (LIN_TRAFO) . Nun zu meinem Problem : Die Ausgangskarte nimmt nur einen Word Datentyp und meine Bausteine haben den REAL Datentyp. Wenn ich einen Konvertierungsbaustein nehme, Schmeist mir Codesys einen Fehler und das Programm wird geschlossen. Könnt Ihr mir helfen? Vielen Dank im Voraus (Datei habe ich angehängt). Die Ausgangskarte ist eine Wago 750-555-08

Post by wbj0t on What the right way to update TCP/COM slave device holding registers ^{CODESYS Forge talk (Post)}
Hi all :) I have an plc. This plc has option to be as slave device. There are TCP -> Serial Slave Device and COM -> Serial Slave Device. There are 4096 ModBus holding registers with mark "internal modify" for the both devices above. So, COM Slave has 4096 registers and TCP Slave has 4096 registers. And, finally, I have an ARRAY[0..4095] OF WORD. This array glued with COM Slave and TCP slave. Yes, I need plc's opportunity to be communication both TCP and COM ways for the same registers. For example, the next task structure: * TASK_0: 1. pou_READ_Registers 2. pou_0 3. pou_1 4. ... 5. pou_N 6. pou_WRITE_Registers At the first pou I read registers for the other pous, after job we have sort of state of the plc. At the last pou (6) we write modified registers. It is a good scenario: some one wrote registers for the job, after job we save these (modified) registers. But, what if registers wrote between 1 and 6 pou by operator, for example, at the 3 pou -> the last pou 'pou_WRITE' will rewrite this request from operator. What the right way to work with this logic? Thanks you.

Post by c3po on Von SNMP auf IIoT wechseln ^{CODESYS Forge talk (Post)}
Hallo, 1. ich bin komplett NEU was Codesys angeht 2. ich muss direkt ein Retrofit machen von V2 auf V3 3. Neue Steuerung: WAGO 750-8211 PFC200. 4. das Projekt in V2 hat über SNMP daten im Netzwerk zur Verfügung gestellt, oder diese gelesen 5. das Projekt in V3 kann SNMP nur noch eingeschränkt nutzen, deswegen wurde mir vom WAGO Support nahegelegt die IIoT Lib zu verwenden. Frage: Wie mach ich das? Konkret: Ich habe die WagoAppSNMP Bibliothek installiert, damit kann ich schon mal Set und Get nutzen (hoffentlich, hab es ja noch nicht getestet, sondern nur programmiert). Ist das ein schlauer Weg, das über diese Lib zu machen? Denn: was macht der SNMP_SET_PLCDATA_WRITEAREA ? Den kann ich über die Wago Lib nicht nutzen und weiß auch nicht, was dieser Baustein konkret tut (Bild im Anhang). Es scheint mir, hier werden Daten auf ein Word im Netzwerk geschrieben? Aber geht das nicht auch einfacher? Es ist ja keine Adresse hinterlegt, wo das hin gehen soll oder? Also, ich verstehe den Baustein nicht so ganz und konnte bisher auch keine Erklärung dazu finden. Vielen Dank schon mal für eure Unterstützung, K.

Post by struccc on Bibliothek: floatingpointutils ^{CODESYS Forge talk (Post)}
The issue s the byte order typically in this case. Can be especially problematic with floating point numbers - even more tricky if transferred with a word based protocol. It is a peasant way to try out the alternatives, dword order can be a-b-c-d, b-a-d-c, c-d-a-b, d-c-b-a where a is the most significant, d is the least significant byte. So all you need is to swap the bytes in your dword, until you get the expected result. If you don't want to mess writing code for this, I'd recommend CAA_Memory library for that: MEM.ReverseBYTEsInDWORD and MEM.ReverseWORDsInDWORD functions would definitively do the trick. Otherwise, can do like this: VAR dwIn : DWORD := 16#11223344; dwOut : DWORD; rOut : REAL; pIN : POINTER TO BYTE; pOUT : POINTER TO BYTE; END_VAR pIN := ADR(dwIn); //pOUt := ADR(dwOut); pOUt := ADR(rOut); pOut[0] := pIN[3]; pOut[1] := pIN[2]; pOut[2] := pIN[1]; pOut[3] := pIN[0]; Ugly, but does the job...

Post by george32 on TCP Server ^{CODESYS Forge talk (Post)}
Thank you for your advice Rinie, I have tried to follow this example but found one problem.When I disconnect with Hercules the system does not acknowledge the lost of its connection this could result in critical errors. Because of this error I am trying to implement the Syssocket library. With this library I am having a problem which I could not solve. I have the following code: ip_adres : STRING :='0.0.0.0'; port : WORD := 5000; iStep : INT := 1; // Socket information Socket_handler : SysSocket_Interfaces.RTS_IEC_HANDLE; Socket_handler_result : SysSocket_Interfaces.RTS_IEC_RESULT; Socket_adress : SysSocket_Interfaces.SOCKADDRESS; Addres_Convert : SysSocket_Implementation.RTS_IEC_RESULT; // Bind information Bind_handler : SysSocket_Interfaces.RTS_IEC_RESULT; // Listener Information Listener_handler : SysSocket_Interfaces.RTS_IEC_RESULT; Addres_Convert := SysSocket_Implementation.SysSockInetAddr(szIPAddress:= ip_adres,pInAddr:= ADR(Socket_adress.sin_addr)); Socket_adress.sin_family:= SysSocket_Interfaces.SOCKET_AF_INET; Socket_adress.sin_port := SysSocket_Implementation.SysSockHtons(usHost:= port); CASE iStep OF 1: // Create Socket Socket_handler :=SysSockCreate( iAddressFamily :=SysSocket_Interfaces.SOCKET_AF_INET, diType:=SysSocket_Interfaces.SOCKET_STREAM, diProtocol:=SysSocket_Interfaces.SOCKET_IPPROTO_TCP, pResult:=ADR(Socket_handler_result)); IF Socket_handler = SysSocket_Interfaces.RTS_INVALID_HANDLE THEN iStep := 1; ELSE iStep := 2; END_IF 2: Bind_handler := SysSocket_Implementation.SysSockBind( hSocket:=Socket_handler, pSockAddr :=ADR(Socket_adress), diSockAddrSize:=SIZEOF(Socket_adress) ); 3: Listener_handler := SysSocket_Implementation.SysSockListen( hSocket :=Socket_handler, diMaxConnections :=1); END_CASE When I am trying to get this working, the SysSockBind function gives a value of 16#207 which means adress already in use. I find this weird because of the IP-adress of 0.0.0.0. I think I am converting the Ip-adress in the wrong way, but the code does not give a error arround this. So therefore I cannot find the solution to this problem. I hope someone could help me with this problem. Thanks in advance George

Post by timvh on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
What maybe helps is the Visu Dialog ST demo project: https://store.codesys.com/en/visu-dialog-st.html This has an application IECOpenDialog where dialogs are opened using the VU.FbOpenDialogExtended function blocks. The fbOpenConfigurationDialog call has a reference (interface) to the "close listener" FB of which it's method is automatically called when the dialog is closed. This way you can create specific function blocks for each dialog when it is closed and do what you want with the data that might have been changed.

Post by voffi on Converting UINT into bytes and converting 2Bytes into UINT ^{CODESYS Forge talk (Post)}
There are some ways. One is to use SHR and SHL and it depends on your byte order in the data array. For Motorola byte order: PROGRAM PLC_PRG VAR u : UINT; byte_array_in : ARRAY [1..8] OF BYTE := [16#11, 16#12, 16#13, 16#14, 16#15, 16#16, 16#17]; byte_array_out : ARRAY [1..8] OF BYTE; END_VAR u := SHL(TO_UINT(byte_array_in[2]), 8) + TO_UINT(byte_array_in[1]); byte_array_out[1] := TO_BYTE(u); byte_array_out[2] := TO_BYTE(SHR(u, 8)); If it's Intel byte order just change 1 and 2 in the array indexes.

Hello everyone, I encountered a problem in the simulation while working. In a test project we set up a Modbus connection. We wanted to simulate this with test values. The connection also worked, but unfortunately the values are frozen and do not report any “current data”.

Kind regards and thanks in advance.

We have it working fine reading and writing data, although we have found an issue we cannot resolve and any suggestions would be helpful. We have noticed that after a while the RS232 stops working. We have tracked this down to the HANDLE hCom keeps increasing and when this reaches 1023 the COM returns an unknown error "5003". Is there a way to reset this hCom reference? Thanks Richard

Post by egau on Mutate Hash table value ^{CODESYS Forge talk (Post)}
Hi, using the ElementCollections Library, why isn't it possible to mutate a value found within a HashTable? From what I understand, the only way to change a value would be to use the RemoveByKey(), followed by AddKeyValuePair(). My goal is to use a Data Structure that works like a Dictionary in Python. The HashTable seems to come close to this, except that the values themselves seem to be immutable... In python, we can mutate a dict easily (see attached picture).
