IFM Controller Connection Issue

Post by janp on IFM Controller Connection Issue ^{CODESYS Forge talk (Post)}
Hi everyone, I’m using an IFM ecomatBasic CR413S controller and having trouble connecting it to CODESYS 3.5. I have CODESYS SP18 installed, as recommended in the manual, and I’ve tried different patches. I’ve also installed all the packages provided on the IFM website for this controller. I can successfully connect to the ecomatBasic template, but I’m unable to connect when using the CR413S-specific template that includes all the inputs and outputs. Has anyone encountered this issue or knows a solution? Best regards, Jan

Post by abuckie on Getting raw value as full resolution for ADS1115 ^{CODESYS Forge talk (Post)}
I just found this and I am getting a value larger than 16 bit, around 81000 something. I am reading a 5 volt value and I am using level shifters for the i2c bus. This is how I have the channel configured: ADS1115.usiAddress := 16#48; ADS1115.ChannelConfigs[0].Active := TRUE; ADS1115.ChannelConfigs[0].PGA := FSR_6144mV; ADS1115.ChannelConfigs[0].InputMux := Single_0; RawAnalogValue := ADS1115.Channels[0].Value; It looks like every value is a multiple of 3. Any idea where to look to fix this? I think i found what I want to change in UpdateChannels Channels[FChannelNo].Value := INT_TO_REAL(WORD_TO_INT(LValue) * GetFullScaleRange(ChannelConfigs[FChannelNo].PGA)) / 2048.0; I try to edit it but I can't, sorry if this is a basic question, I am new to CODESYS.

I am looking for the same thing, I am trying to edit a library I downloaded but I found that the functions are read only. The link above is broken, should I be looking somewhere like here? https://content.helpme-codesys.com/en/LibDevSummary/index.html

Post by jvfred on Reading a negative number ^{CODESYS Forge talk (Post)}
I have a Codesys-based Eurotherm E+PLC400 connected to Codesys HMI SL for visualization. I am also bringing in several Pressure Indicators via the Ethernet. Everything works; however, the Pressure indicators sometimes read a negative value. When they do, the displayed value on the screen reads "65532." While I know what it represents, the customer freaks out and wants it to read "0" or a negative number. The value comes in as an integer, just in case that matters. Does anyone have any ideas?

Are these variables already declared in the IO list? It looks like it's trying to create new variables instead of mapping them to the existing ones.

Does anyone know how to access the ModbusTCPSlave_Diag.ComState without declaring each one by the device name? I attached them to an array but since I may have dozens of devices this is still a bad solution.

Post by milan-svarny on ModbusFB.ClientSerial Problem with Reply Timeout ^{CODESYS Forge talk (Post)}
Hi All, I have problem with ModbusFB.ClientSerial. I'm using 4 different port for Modbus communication. After some time of running program ClientSerial stops to receive data to reply buffer and all request finish with Reply Timeout. The Device sent reply correctly,that it is visible on oscilloscope and it is possible to see that data( reply )are in the device. If the usbtty device is read over external app. then it is possible to see all data which were not taken by ModbusFB.ClientSerial. The stack does not overflow or something , program runs correctly forward and no exceptions or something. The main problem it is that when the error occur than it is not possible to reset port or something or maybe i'm doing it wrong way. please help me with this issue. Thank you for any help in advice Milan

Post by canplum on Codesys 3.5.21 fails to copy file to USB ^{CODESYS Forge talk (Post)}
Although I have set in /etc/codesyscontrol/CODESYSControl_User.cfg the [SysFile] PlaceholderFilePath.1=/media/pi, $usb$ PlaceholderFilePath.1.View=1 PlaceholderFilePath.1.Volatile=1 I am not able to copy a file to this directory defined by the placeholder. Neither SysProcess.SysProcessExecuteCommand2 nor SysFileCopy nor FileCopy is working. If I try to copy the same file to /home/pi all is working fine. I also can create and open a different file by using SysFileOpen. I don't understand why the system allows to open (create) and write files into that directory but doesn't allow to copy into it. Obviously there is a rights problem with the USB drive. I have already set the permissions to drwxr-xr-x 2 and the user to pi but without any success. With 3.5.16 I never had such an issue. Is there anybody with some hints how to solve that problem? Cheers, canplum

Post by canplum on Codesys 3.5.21 kann Datei nicht auf USB kopieren ^{CODESYS Forge talk (Post)}
Obwohl ich in der Datei /etc/codesyscontrol/CODESYSControl_User.cfg eingestellt habe die [SysFile] PlatzhalterDateipfad.1=/media/pi, $usb$ PlatzhalterDateipfad.1.Ansicht=1 PlatzhalterDateipfad.1.Flüchtig=1 Ich bin nicht in der Lage, eine Datei in dieses durch den Platzhalter definierte Verzeichnis zu kopieren. Weder SysProcess.SysProcessExecuteCommand2 noch SysFileCopy oder FileCopy funktionieren. Wenn ich versuche, die gleiche Datei nach /home/pi zu kopieren, funktioniert alles einwandfrei. Ich kann auch eine andere Datei mit SysFileOpen erstellen und öffnen. Ich verstehe nicht, warum das System das Öffnen (Erstellen) und Schreiben von Dateien in dieses Verzeichnis erlaubt, aber das Kopieren in dieses Verzeichnis nicht zulässt. Offensichtlich gibt es ein Rechteproblem mit dem USB-Laufwerk. Ich habe bereits die Berechtigungen auf drwxr-xr-x 2 und den Benutzer auf pi gesetzt, aber ohne Erfolg. Mit 3.5.16 hatte ich nie ein solches Problem. Hat jemand einen Tipp, wie man dieses Problem lösen kann? Vielen Dank! canplum

Programmatically clearing or syncing Data Source Manager cache? ^{CODESYS Forge talk (Thread)}
Programmatically clearing or syncing Data Source Manager cache?
Last updated: 2025-05-23

Post by kuegerls on Programmatically clearing or syncing Data Source Manager cache? ^{CODESYS Forge talk (Post)}
Hi everyone, is there a way to programmatically clear the cache of the Data Source Manager in CODESYS so that variable values are re-synchronized from the OPC UA server (Symbol Configuration with OPCUA features)? Alternatively, is it possible to trigger a manual synchronization of data source variables from within the application code at runtime? Here’s the situation: A variable is first written by the OPC UA client to the server in one state of a state machine and changes to another state – so the initial communication works. Later, the server changes the variable value, but the client does not receive or reflect the updated value, unless the variable is actively written again. I’m looking for a way to force the client (data source manager) to re-read or refresh the variable state from the server, possibly by clearing the internal cache or triggering a sync. Any ideas or suggestions would be greatly appreciated! Thanks!

Post by lbouchard on CANOpen SIL2 error: UNSAFESTACK_NOT_OPERATIONAL ^{CODESYS Forge talk (Post)}
Hello, Working in 3.5 SP11 32 bit and using the 3S CANopenSafety Slave 3.5.11.0 library on an IFM CR711S. The 3SCSSD.CANOpenDevicesSIL2 function block keeps throwing "UNSAFESTACK_NOT_OPERATIONAL" Additionally, the Status of the device gives "There was an error accessing an I/O parameter". Any ideas on where my issues may lay? I have not found any good documentation that would explain the issue.
