Post by peterned on Programatically restart Codesys OPC UA server? CODESYS Forge talk (Post)
Hi, I'm using a Festo Codesys PLC (CPX-CEC-C1-V3), which is connected to a HMI panel. Both exchange data via OPC UA. Occasionally, the HMI stops displaying data, and looks as if there is no connection. If the HMI stops, the only way to make it work again is to restart the PLC. Restarting HMI has no effect. When the PLC is restarted, HMI starts working normally again. Is it possible to restart the OPC UA server from PLC code? I hope this will make fixing the HMI possible without a PLC restart. Thanks

Post by sigurdrb on Read codesys version in the codesys application CODESYS Forge talk (Post)
Hi! I want to read the codesys version into the project, so I can highlight it in the SCADA system. VAR dwVersion : DWORD; END_VAR SysTarget.SysTargetGetVersion(pulVersion := ADR(dwVersion)); This gives me the value 100859909. I tried to search ths up and found som older post (https://forge.codesys.com/forge/talk/Runtime/thread/a55981ff4d/) that said each 4 bytes reads a number in the version. Example is 50662666 = 16#03050D0A which reads to V3.5.13.10 When I run this code I get the value 100859909, which I cant translate to anything meaningful. I am running it on Codesys V3.5.19.70. Help appreciated!

Post by george32 on TCP Server CODESYS Forge talk (Post)
Dear people, I would like to create a TCP server in my PLC program. The TCP server needs to communicate with an external device. I have been searching the internet and found that the libraries Syssocket or CAA NetBaseSrv are two possible solutions to create a TCP server. From what I have read, CAA NetBaseSrv is more user-friendly to implement than the Syssocket variant. However, I am still struggling to actually implement this library. Foremost is my little knowledge about creating a TCP server and how to read/understand each function block, especially the outputs of some blocks and the types, e.g. server has an output CAA.Handle, but I cannot find the explanation of CAA.Handle. I tried to find a good document that can help me understand how to implement a TCP server, but I could not find it. Thank you in advance, George

Post by pernockham on Gateway in China - "Gateway not connected" CODESYS Forge talk (Post)
Trying to communicate (from Europe) with/to a unit located in china, the communication seems blocked/stopped. The edge gateway is installed in a linux environment and was possible to link to my Automation server account using the "Automation service tool". However it seems the unit cannot communicate with the Automation server (a Network scan will give the message "Gateway not connected"). (I have tested the eq. setup with units locally which works.) Anyone having experience situation similar to this and if its possible to make this work? Will a VPN be needed possibly? Other tips?

Post by fajean on Issues with "Add all instance path" CODESYS Forge talk (Post)
In the past, we have routinely used the "add all instance paths" function to automatically add variables to VAR_CONFIG lists. My recollection is that compiling a project did not require VAR_CONFIG to be fully populated, and, once successfully compiled, instance paths could be added. Errors related to missing declarations, if I recall correctly, were thrown when downloading to the PLC, they did not prevent a successful compile. At some point, it stopped working. Missing declarations in a VAR_CONFIG now cause a compile error, so the application is never "current", the only reason I can see being the missing VAR_CONFIG declarations themselves (no other error). We observe the same behavior across all our projects. This is really aggravating, and I must be missing something simple. We use 3.5 SP17p3, 64 bits. Can anyone help?

Post by alexgooi on Is it possible in the log to see previous shutdown CODESYS Forge talk (Post)
Hi DavidBo, In general Codesys is used to control equipment and an exception is the worst thing that can happen in your installation. If you cannot prevent the exception from triggering, you could implement a Try catch statement, with this solution your controller keeps on running and you are able to handle the exception. __TRY //This statement will trigger an exception Result := 4/0; __CATCH(exc) //Handle the exception HandleException(exc, strExceptionText => strExceptionText); // From the Codesys help file //Create a log file //-------------------------------------------------------- __ENDTRY What you also could do is implement implicit checks, these functions cover most of the exceptions (like dividing by zero) See picture But in general avoid a complete controller shutdown!

Post by riccardo on Web Browser special tools errors CODESYS Forge talk (Post)
Goodmoning everyone, I hope a codesys tecnichian will see this post. I serched on the forum and I found many topic about this tool but very few reaplies. I am tring to use the Web Browser tool, but it doesn't seem to work properly. I put several links in several forms: https://google.com http://google.com/ http://www.google.com http://www.google.com/ http://www.studiojomega.it/ . . . https://192.168.1.101/u-os-app-codesys/application/visualization/webvisu.htm But I obtain always errors; mainly 400 and 404 and in the normal visu this message appears "www.Google.com has refuse the connection". Is the codesys browser able to work as every other browser or has it some limitation? There is some particular precaution to consider when I pass the link to the codesys browser? Thanks in advance, Riccardo

Post by reinier-geers on License problem gateway CODESYS Forge talk (Post)
Epis doesnt want Softmotion. I thought it was about the price. If it was possible it would be working already and i dont need an extra licence. Thats the problem of codesys. The software is running but hangs on its license. Epis made it posible to see the stick. I can see the license. Softmotion is there from 3.5.14.Xx Like is said And Motion control is alrady posible 15 year ago. And i only need a Sync of 2 drives. I want a good solution not a refund. Dont point to the manufacturer. The software is made by 3s not by epis .

Post by westcountryewe on Persistence Variables missing and DO NOT retain from Persistence Channel when using Boot Application CODESYS Forge talk (Post)
We've been experiencing an issue through SP18, SP19 and now SP20 where the Persistence Variables do not retain if we upload our program via a Boot Application. If we use the exact same program, and perform a Direct Upload via the Laptop and Ethernet connection, the Persistence Variables work exactly as expected. I have submitted 2 bug support tickets but I haven't had a response back from Codesys. Has anybody experienced the same issues and discovered a workaround? We have a requirement to utilise the Boot Application method because of logistical restrictions of being able to get out to every site, so at the moment it's a bit restriction.

Post by gatto on Two licenses have to be installed forgot to enable one license CODESYS Forge talk (Post)
Sorry, I've never used Raspy. Maybe someone else can help. From personal experience, I've had license activation issues, but it was caused by my company firewall, which was blocking traffic from the Codesys license server. So I found that the license was listed as activated on the server (and therefore used and no longer activable), but it wasn't present in the PLC. I solved the problem by using an unblocked internet connection when I needed to activate the purchased license ticket. Since then, the activation process has always worked, and I've never lost any licenses.

Post by hannibal on Codesys Trend - setting Y axis minimum and maximum as variables - error CODESYS Forge talk (Post)
I am experiencing an issue when trying to define the Y-axis limits in a Trend Graphic using variables. When I set the Minimum and Maximum values as variables, an error is triggered. My goal is to make the Y-axis limits dynamic so they can adjust according to the installation. Both variables are initialized as follows: gP_YMin = -100.0 gP_YMax = 100.0 However, I still get the following error: "The minimum axis value must be less than the maximum axis value" Does anyone have an idea why this is happening or how to resolve it?

PROGRAM ModbusClient VAR initDone : BOOL := FALSE; errorID : ModbusFB.Error; client : ModbusFB.ClientTCP; timeout : UDINT := 500000; replyTimeout : UDINT := 200000; aUINT : ARRAY [0..8] OF UINT; clientRequestReadHoldingRegisters : ModbusFB.ClientRequestReadHoldingRegisters; clientRequestsCnt : UINT := 0; clientRequestsProcessCnt : UINT := 0; ipAddress : ARRAY[0..3] OF BYTE := [10,54,0,72]; END_VAR IF NOT initDone THEN initDone := TRUE; client(aIPaddr:=ipAddress, udiLogOptions:=ModbusFB.LoggingOptions.All); client(xConnect:=TRUE, ); clientRequestReadHoldingRegisters(rClient:=client, udiTimeOut:=timeout, uiUnitId:=1, uiStartItem:=0, uiQuantity:=4, pData:=ADR(aUINT[0]), udiReplyTimeout:=replyTimeout); clientRequestReadHoldingRegisters.xExecute := TRUE; clientRequestsCnt := 0; END_IF clientRequestReadHoldingRegisters(rClient:=client, udiTimeOut:=timeout, uiUnitId:=1, uiStartItem:=0, uiQuantity:=4, pData:=ADR(aUINT[0]), udiReplyTimeout:=replyTimeout, xExecute := TRUE); IF clientRequestReadHoldingRegisters.xError THEN clientRequestsCnt := clientRequestsCnt +1 ; errorID := clientRequestReadHoldingRegisters.eErrorID; END_IF clientRequestReadHoldingRegisters(rClient:=client, udiTimeOut:=timeout, uiUnitId:=1, uiStartItem:=0, uiQuantity:=4, pData:=ADR(aUINT[0]), udiReplyTimeout:=replyTimeout, xExecute := NOT clientRequestReadHoldingRegisters.xExecute); When the system is running I do get the following on the logs: 2024-05-13T10:18:07.443Z: Cmp=MODBUS lib, Class=1, Error=0, Info=0, pszInfo= Client.RequestProcessed ClientRequest,16#0164ADC561A0 unitId=1 fc=ReadHoldingRegisters id=2070 state=Error 2024-05-13T10:18:07.443Z: Cmp=MODBUS lib, Class=1, Error=0, Info=0, pszInfo= ClientRequest,16#0164ADC561A0 unitId=1 fc=ReadHoldingRegisters id=2070 change state Error -> None timestamp=63843421226 2024-05-13T10:18:08.444Z: Cmp=MODBUS lib, Class=1, Error=0, Info=0, pszInfo= ClientRequest,16#0164ADC561A0 unitId=1 fc=ReadHoldingRegisters id=2071 change state None -> Init timestamp=63844421420 2024-05-13T10:18:09.444Z: Cmp=MODBUS lib, Class=1, Error=0, Info=0, pszInfo= ClientRequest,16#0164ADC561A0 unitId=1 fc=ReadHoldingRegisters id=2071 change state Init -> Error timestamp=63845421675 But the errorID is jumping between OK and RequestNotProcessed. Any help is very appreciated which gives me a hint what I'm doing wrong. Thanks

Post by askic on Generate FBs from source CODESYS Forge talk (Post)
Hello, I'm coming from Siemens (TIA) world and currently learning Codesys. I'd like to know if there is an option to add external txt file with ST code for creation of a function block and then use this file as a source file from which FB will be generated? For example, in TIA, there is an option add external source file to the project structure and then use option "Generate blocks from source". This would create a FB. Does Codesys have something similar? This external source file would look like this: FUNCTION_BLOCK Scaling VAR_INPUT x, k, n : REAL; END_VAR VAR_OUTPUT y : REAL; END_VAR VAR END_VAR y := k*x+n; END_FUNCTION_BLOCK

Post by aria13 on Has anyone fed ESP32 sensor data into CODESYS (via MQTT/Modbus)? CODESYS Forge talk (Post)
Has anyone tried sending live sensor data from an ESP32 into a CODESYS runtime (for example via MQTT gateway or a Modbus bridge) to trigger PLC logic? I was reading an ESP32 → MQTT tutorial (https://www.theengineeringprojects.com/2021/11/esp32-mqtt.html) that shows how easy it is to publish sensor data from an ESP32, and I’m wondering how practical that is when tying the stream into industrial control software like CODESYS. I’ve also seen Arduino forum threads where people relay sensor streams to MQTT brokers and Raspberry Pi projects that bridge MQTT→Modbus, so I’m mainly curious about real-world issues: reliability, message latency, and simple patterns you’d recommend for safe PLC integration. Any tips, examples, or gotchas from folks who’ve done this?

Post by artem1223 on Synaxis of library declarations in the ST CODESYS Forge talk (Post)
Codesys 3.5 17.30, plc - crevis GN-9373. I need to use RTC of pls for write in registers (need to check difference of writen 100 and 200 registers). For this i try to use SysTimeRtc (SysTimeRtc.SysTimeRtcGet) but its not working. After it i tryed to use SysTimeGetMs and something like this but still not working. Library? Mb but check project, SysTime with SysTimeRtc already, all what i know - already is here. Its my first try to learn ST (early used fbd and ladder, yeah), pls help with it. Mb problem with a syntaxis, but im not sure.

Post by baotthitawat on SCADA Systems Are Becoming Easier to Integrate With Modern Applications CODESYS Forge talk (Post)
One thing I’ve been seeing recently is that more industrial systems are starting to expose realtime SCADA data through APIs instead of keeping everything isolated inside the local monitoring software. This makes integration much easier for cloud platforms, mobile dashboards, AI analytics, and enterprise applications that need realtime industrial data. Instead of exporting reports manually or building complicated middleware, APIs allow external systems to access SCADA data directly in realtime. I think this becomes especially useful for applications like wastewater treatment monitoring, where operators need better visibility into alarms, equipment status, and operational conditions across different locations. Feels like modern SCADA is slowly evolving from a standalone monitoring platform into part of a larger connected industrial ecosystem.
