Post by acc00 on Main Task cycle too long leading to PLC Fail

I have 2 Wago PFC200 PLC, running with Runtime SP19 Patch 5, with the Redundant application. The PLC communicates as Modbus Master with at this moment 15 Modbus Slaves -later there will be 28 in total- (Drives, Power management units,...). These devices are connected in 2 rings (1 ring of Drives, 1 ring of Power Management units), with 2 Managed Moxa Switches being part of the ring. Each PLC is connected to one of these switches. The issue I'm encountering is that the Cycle time of the Active PLC goes very high when I'm closing the Drive ring (simulating an issue on one Cabinet supply, resulting in that one Drive shut down, which can happen on field quite often). As a result of this long cycle, the PLC fails and goes to Exception, and the Passive PLC does not take control of the system. A normal cycle is around 30ms for the Main task, and a few ms for the Ethercat task. When I monitor with Profiler, I see that in this Maximum Cycle, the main Task is only taking 13ms, so I'm not sure where the PLC is hanging for so long. Is the remaining cycle time the Redundant management/sync or something else? Thank you in advance.

Hi, I'm trying to monitor a specific PGN which I have it sending a pulse every 500mS Problem: Using the Watchdog for the ECU does not really help me as I have multiple instances with separate PGNs, if a PGN goes ghost, the ECU watchdog won't be flagged as the others will be running. I found the J1939.ReceiveWatchdog & J1939.ReceiveParameterGroup function blocks and they seem like a good solution for my problem, I just can't get them to work from my understanding you just build the J1939.ReceiveParameterGroup once and then connect it's output to the J1939.ReceiveWatchdog, here's my CODE for the setup HEARTBEAT_TIMER(IN:= TRUE, PT:= T#1000MS); //turn-on delay because of initialization race IF HEARTBEAT_TIMER.Q= TRUE THEN Glob_Var.DisplayReceive.xExecute:= TRUE; Glob_Var.DisplayReceive.itfECU:= Valve_X; Glob_Var.DisplayReceive.dwPGN:= 65511; Glob_Var.DisplayWatchdog.xEnable:= TRUE; Glob_Var.DisplayWatchdog.itfParameterGroup:= Glob_Var.DisplayReceive.itfParameterGroup; Glob_Var.DisplayWatchdog.tTimeout:= T#1500MS; END_IF Notes: Glob_Var.DisplayReceive is of type J1939.ReceiveParameterGroup Glob_Var.DisplayWatchdog is of type J1939.ReceiveWatchdog The above code is done once and not cyclically I'm monitoring Glob_Var.DisplayWatchdog.xError cyclically

Hi Dear All, I'm using my raspberry PI4 as a CoDeSyS PLC (Build from scratch with custom electronics). I was able to implement all fieldbuses with the exception of Modbus Serial. I'm using the internal Port (GPIO) and I configured it in /etc/Codesyscontrol_user.cfg the following away: [SysCom] Linux.Devicefile.1=/dev/ttyUSB0 Linux.Devicefile.2=/dev/ttyS0 I'm using COM2 on Master configuration. I'm using a interface board from TTL/RS485 (bidirectional board), and it's works perfectly with other devices but not in CoDeSyS. I'm able to send data with python script and read it on my pc using putty, but when I use a modbus slave simulator to interface with codesys I always get red icons on master and slave. (Please find image attached). I'm pretty shure that this might be a bad parameter on my CoDeSyS runtime configurstion file. Can someone help me? I'm stuck and this is for my master degree certification.

Hello, I’m in Codesys 3.5.20.40 and I try to declare the variable ´var1´ but I get an error. here : https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_rules.html i read : Backtick identifiers By using backticks, characters can also be used in identifiers that are not normally permitted in identifiers, such as special characters. The acute accent character is used for backticks: ´ (Unicode: U+02CA) The use of backticks is recommended in order to be able to use the same identifiers in CODESYS as in other programming languages or documents, such as circuit diagrams. Any character may be used between two backticks, except line breaks and other backticks. Keywords are also allowed as identifiers between backticks. Examples: ´Variable+9´ ´INT´ The backticks are part of each identifier and therefore var1 and ´var1´ are two different identifiers. Example PROGRAM PLC_PRG VAR var1 : INT; ´var1´: INT; END_VAR var1 := var1 + 1; ´var1´ := 12; Are there any limitations or is something missing in my development environment?

Hello everyone, I am currently using OPC UA in CODESYS with the security mode BASIC256SHA256 – Signed and Encrypted. The OPC UA Server is running on an RTE CX device, and the HMI is running on another computer. I have reviewed many CODESYS documents and successfully established communication when the security mode is set to None with Anonymous login. However, when security is enabled, the server does not provide its certificate for the CODESYS HMI client to trust. Interestingly, the client can send its certificate to the server, and UAExpert works normally, but the CODESYS HMI client does not receive the server certificate. Can anyone help clarify what I might be missing? I have been stuck on this issue for three days. If I missed or misconfigured any step, please let me know. I believe I am stuck at step 15 in the following CODESYS guide: Encrypting the Communication of a Data Source OPC UA Client https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_encrypt_communication_data_sources_opc_ua_client.html Thank you very much.

Hello, I am currently trying to use the AM243 LaunchPad as a PROFINET device and connect to it using CODESYS. In my setup I am also using a Raspberry Pi running the CODESYS PROFINET Runtime, which acts as the PROFINET controller. The setup of the Profinet controller is correct, so all devices are in the same subnet. However, I encounter an issue when scanning for PROFINET devices in CODESYS. The AM243 LaunchPad appears in the scan results, but the following error is reported: RPC Aborted: 0x16C9A049 Additionally, CODESYS shows the message that the identification data is not available and the IP address should be checked. Because of this error, the controller cannot establish a connection to the device. Another observation is that I cannot ping the AM243 LaunchPad from my PC, even though I configured what should be the correct IP address. Setup: PROFINET Device: AM243 LaunchPad PROFINET Stack: Industrial Communication SDK example PROFINET Controller: Raspberry Pi running CODESYS with PROFINET Runtime Engineering PC: CODESYS IDE Network: Ethernet connection between PC, Raspberry Pi, and AM243 In the attachments there is a screenshot of the corresponding error. Did anybody had the same error? Any hints or debugging suggestions would be greatly appreciated. Thank you!

I also previously tried communicating with RapidSCADA and received the following error: Endpoint with the specified security options not found. And when I try to connect with "none" in the security policy, I get this error: BadSecureChannelClosed I have tried almost all the solutions available online and have not found a solution. I hope you can provide me with a solution that solves this problem. Thanks in advance

You are welcome. Also note, that it's valid only if you modbus-device use same real/float value representation (IEEE 754). That's true for most of systems. But some devices may have other representation, such as integer + position of the decimal point, for example 123.456 is integer = 123456 and position = 3 Also note, that, ones again, depending on endianess of each system, you may also need to swap not just words, but bytes. TYPE u_Real : UNION rVal:REAL; wVal:ARRAY[0..1] OF WORD; bVal:ARRAY[0..3] OF BYTE; dwVAL:DWORD; //same as previous, may be easier to specify the MB register END_UNION END_TYPE than swapping may be something as VAR A,B,C,D:BYTE; //Bytes of the real value uIn, uOut:u_Real; rVal:REAL; ModbusReg1,ModbusReg2:WORD; END_VAR uIn.rVal:=rVal; uOut.A:=uIn.D; uOut.B:=uIn.C; uOut.C:=uIn.B; uOut.D:=uIn.A; ModbusReg1:=uOut.wVal[0]; ModbusReg1:=uOut.wVal[2]; Or you even need to reorder bits... Ones again, sending float/real values is not defined by Modbus protocol itself, so it is hardware- and software-dependent. The Modbus Poll (and most of modbus tools) have configuration parameters that will properly swap bytes on their side. Ones again, that's very helpful: https://www.scadacore.com/tools/programming-calculators/online-hex-converter/

Hello, We are facing a critical issue with CODESYS SoftRedundancy that we have been unable to resolve despite extensive troubleshooting. HARDWARE: 2× HP EliteDesk 800 G9 SFF Intel Core i7-14700 (20 cores) 16GB RAM, 512GB NVMe SSD Windows 11 IoT Enterprise LTSC 2024 NIC1: Built-in Intel GbE NIC2: Intel I210-T1 PCIe (NIC team) SOFTWARE: CODESYS Control Win V3 - x64 Version 3.5.22.10 CODESYS SoftRedundancy SL Server 1 IP: 172.10.10.101 (PLC1 — Active) Server 2 IP: 172.10.10.102 (PLC2 — Standby) CURRENT CODESYSControl.cfg: [CmpRedundancy] BootupWaitTime=120000 StandbyWaitTime=12100 SynchronousTimeout=12100 [CmpSchedule] ProcessorLoad.Maximum=80 WatchdogTime=12000 WatchdogTimeoutAction=0 CONFIRMED WORKING: PLC1/PLC2 identification configured via IDE Connection IP configured via IDE AutoSync enabled and written via IDE Normal Active/Standby operation working Server 2 auto-promotes when Server 1 completely fails PROBLEM DESCRIPTION: When NIC1 cable is removed from Server 1 — both servers go to standalone mode. When NIC1 cable is reconnected — both servers remain in standalone indefinitely. Neither server auto-recovers to Active/Standby without manual CODESYS service restart. AutoSync fires (!!! Autosync !!! visible in log) but recovery does not complete. Tested with direct cable (no NIC team) — same result. Confirmed not a hardware or NIC teaming issue. KEY LOG MESSAGES: "Timeout: No sync message RMSG_StartCycle (5) from master: Standalone" "Socket on other side closed gracefully 0" "Standby PLC: Open acyclic work socket failed" "Connection broke after 11806ms. Check BootupWaitTime." Autosync(fires but does not complete recovery) PCAP ANALYSIS (Wireshark): CODESYS sync stops completely at T+3s Server 1 sends TCP FIN on ports 1206 and 1208 at T+5s No CODESYS redundancy traffic for remaining 24 seconds Both servers stay standalone indefinitely WHAT WE HAVE TRIED: StandbyWaitTime = 12100ms SynchronousTimeout = 12100ms WatchdogTime = 12000ms (less than StandbyWaitTime) AutoSync enabled NIC2 set as Standby adapter Disabled Windows Network Discovery Direct cable test — rules out NIC hardware QUESTION: Per official CODESYS documentation: "No automatic Reconnect is included in the functional scope of the redundancy components. You can program the triggering of a reconnect." Is RDCY.Synchronize() the correct function to add to our application for automatic recovery after both PLCs go standalone? What is preventing auto-recovery when AutoSync is enabled and PlcIdent is correctly set? Thank you for your support.

Hallo, ich habe https://store.codesys.com/de/codesys-in-building-automation-examples.html runtergeladen und mit dem Installer und Adminrechten installiert. Jedoch finde ich auf C: keine *.project* Dateien. Kann mir jemand erklären wie ich an die Examples dran komme? Auch von Wago habe ich Packages bekommen in denen Beispiele enthalten sind. Auch hier finde ich nix. (Googel habe ich gefragt. Aber mit den Stichworten kommen viele Treffer die alle nicht hilfreich waren.) In der Hilfe von Codesys habe ich natürlich auch gesucht, aber auch hier nichts erklärendes gefunden. Angeblich findet sich was in C:\Programme\CODESYS 3.5.19.40\CODESYS\Projects oder auch unter C:\Users\BENUZTERNAME\CODESYS Examples Aber wie geschrieben finde ich auf C:\ nix was ein Beispiel wäre. Wäre echt super wenn mir jemand einen Hinweis geben könnte. Danke im Vorraus, Martin

Hallo, mal wieder war der Fehler vor dem Computer, bzw. waren es die Programmierer. Die Dateien sind tatsächlich im Ordner C:\Users\BENUZTERNAME\CODESYS Examples Aber nicht in dem der vor dem Computer sitzt, sondern im Administrator-Verzeichnis. Eine mächtig dämliche Sache. Und das alles ohne Hinweise in irgendwelchen Anleitungen oder Meldungsfenster beim installieren. Bei meiner suche mit *.project habe ich natürlich keine Adminrechte, deswegen wurde mir nichts angezeigt. Danke an alle die meine Beiträge gelesen haben. Danke an alle die darüber nachgedacht haben :-) Vielleicht hilft mein Thread mal jemandem. Gruß Martin PS: Mache Firmen nennen die Beispieldateien nicht Examples sondern Samples.

CODESYS Forge

Hallo, das Thema ist ja etwas offtopic. Aber ich kann gerne mal von meiner Erfahrung berichten: Nachdem ich von 2020 bis 2023 immer einen MacBook Pro mit Intel CPU hatte (i9/32GB) und nun seit Januar 2024 mit dem M3 Max unterwegs bin kann ich Nachfolgendes berichten. Infos zu den Aufgaben, die ich damit erledige: Die Runtime nutze ich nicht auf dem Mac (Wenn ich von Mac rede, dann meine ich damit die Win11 ARM64 Parallels Umgebung) Ich nutze die IDE für Library development und für automatisierungs Tests von CI/CD jobs. Weiterhin öffne ich oft große Projektarchive mit teilweise 160 MB. Erfahrungen zur Installation von CODESYS Versionen: Ich habe einige Versionen installiert, unter anderem, 3.5.14.4, 3.5.17.2, 3.5.16.3, 3.5.18.4 und 3.5.19.6. Ich hatte mit keiner einizgen Installation ein Problem. Die Installation lief immer ohne Probleme durch. Runtimes (Control Win) installiere ich nicht. Ich nutze linux basierte Zielsysteme und bei bedarf eine Windows VM auf einen entfernen Host mit X64. Lokales Gateway läuft ebenso Sonstige Erfahrungen: Ich nutze viele Komponenten Querbeet: Alarming, AC Persistence, Symbol Konfiguration, CFC und ST Editor, externes Packages wie STWeep, Git für Library Entwicklung, Visu, etc. Mit keiner dieser "Komponenten" hatte ich schwierigkeiten oder einen Unterschied zu x64 systemen festgestellt. Man muss aber auch sagen, dass das alles nur ein kleiner Bruchteil ist, was die CODESYS Welt beinhaltet, deshalb sind diese Aussagen auch nur subjektiv aus meinem Erfahrungsbereich. Für das Entwickeln von Libraries sehe ich keine Performance Einschränkungen. Ganz im Gegenteil, für das, dass hier eine emulation stattfindet, ist es erstaunlich schnell. Meiner Meinung nach sind sogar einfache und kleine Projekte schneller als beim Intel Mac. Die Akku Leistung mit dem Mac und Parallels ist fantastisch. Lüfter hört man nicht mal bei der Nutzung von CODESYS. Beim Intel konnte ich sonst ein Spiegelei auf der Abdeckung zubereiten... Was evtl. etwas langsamer ist bzw. mir manchmal so vor kommt ist, der CFC Editor im Online Mode. Aber hierzu fehlt mir ein richtiger Vergleich. Fazit: Ich bin selbst erstaunt wie gut die CODESYS IDE auf einem ARM64 emuliert wird. Ich muss aber auch sagen, dass ich jederzeit eine x64 Workspace zur Verfügung habe, falls was nicht funktionieren sollte. Das habe ich mir extra zum Umstieg zu gelegt. Bisher habe ich es jedoch noch nie benötigt, da meine Anforderungen alle erfüllt werden. Es sollte einem aber bewusst sein, dass dies keine supportete Umgebung ist und man auch bei spezifischen Problemen keinen Support erwarten sollte. Ich nutze CODESYS ca. 4-12 Stunden die Woche und ich warte immer noch auf etwas, um meine X64 Cloud Workspace mal zu verwenden... Vielleicht hilft dir dies ja etwas bei der Entscheidung.

I just installed codesys runtime on a raspberry pi Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz (Compute Module 4) I am running on Codesys control for raspberry pi 64 SL ver 4.13.0 and I keep getting a crash after about five to ten minutes. This program was running fine on a 32bit system with runtime 4.8 previously but they upgraded the panel PC cause it got smashed. Looking at the logs I see this error "ERROR: GetNetLinkSockAndInfoByMac(): could not open netlink socket: Too many open files" at the time of crash. I do have a UDP socket open for a serial to ethernet adapter and im wondering if maybe its opening a bunch of sockets and while receiving messages, Im not sending anything to the device only receiving. Below is the code used for the UDP VAR // Scale Comm fbPeerServer : NBS.UDP_Peer; ipAddress : NBS.IPv4Address; fbReceive : NBS.UDP_Receive; xPeerActiv : BOOL := TRUE; abyReceive : ARRAY [0..255] OF BYTE; sLastValidReceive : STRING(255); udiIndex : UDINT; END_VAR IF xPeerActiv AND NOT fbPeerServer.xBusy THEN ipAddress.SetInitialValue(ipAddress := gvlSettings.sIPAddres); fbPeerServer(xEnable := TRUE, itfIPAddress := ipAddress, uiPort := gvlSettings.uiPort); END_IF fbPeerServer(); fbReceive(xEnable := fbPeerServer.xBusy, itfPeer := fbPeerServer, pData := ADR(abyReceive), udiSize := SIZEOF(abyReceive)); IF fbReceive.udiCount > 0 THEN IF fbReceive.udiCount < SIZEOF(sLastValidReceive) THEN SysMem.SysMemCpy(pDest := ADR(sLastValidReceive), pSrc := ADR(abyReceive), udiCount := fbReceive.udiCount); // Set End of String sLastValidReceive[fbReceive.udiCount] := 0; END_IF END_IF If anyone as seen this I could really use some help figuring it out.

Hi TK_Jenssen did you found a solution I am setting up the samelike gantry only with two z-axes which are mounted on fix position with an X axes between the two z-axes. The movement and position of both z-axes must be very well aligned and calibrated. Maybe also to be adjusted by programming. Can you sent an example of your solution?

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
