Post by salvadegianluca on SysPlcCtrl23 and C0338: The library 'cmperrors interfaces, 3.5.5.0 (system)' is supported just in 32 bit applications ^{CODESYS Forge talk (Post)}
Good afternoon to everyone; I'm stuck with this error and I don't know how to get out from it... I tried several time googling for alternative systems to control the PLC applications and resets but without success. I would like to realize the possibility to reset the CPU and to start/stop the applications as it was possible with the SysPlcCtrl23, but this library is no longer supported in 64 bit systems and it seems due to the cmperrors interfaces sub library that was included in the above said one. Someone found a work around for this issue?

Post by kuegerls on SysProcessExecuteCommand2 and CANopen Device ^{CODESYS Forge talk (Post)}
Hello, CODESYS Control is running on my RevPi, and my system communicates over a CANbus with a master using the ConnectCan module (Slave - CANopen Device). The communication works perfectly fine so far. However, as soon as I call a Python script with "SysProcessExecuteCommand2" that creates a CSV file and executes without errors, the master does not adopt any changes to the Transmission Process Data Objects (TPDOs). I don't quite understand what one has to do with the other, and perhaps someone can help me with this. Here is my script call: SysProcess.SysProcessExecuteCommand2(pszCommand:='python /home/pi/test.py', pszStdOut:=sCMDOutput, udiStdOutLen:= SIZEOF(sCMDOutput), pResult := ADR(eResult)); Thank you in advance! Best regards, Stefan

Post by malte on OPC UA multiple Endpoints ^{CODESYS Forge talk (Post)}
My CODESYS OPC UA server provides endpoints using both the hostname and the IP address. Connecting via the IP address works fine, but connecting via the hostname does not. The endpoint list shows both opc.tcp://<hostname>:4840 and opc.tcp://<ip>:4840. When using the hostname, the OPC UA client (UA Expert) fails to connect. Using the IP address connects without issues. Main goal is to conect via Python but opcua-asyncio seems to prefer the hostname. How can I configure CODESYS or my system so that the OPC UA connection via hostname also works properly or disable it completly? Running Codesys for PFC200 sl 4.18.0.0

Post by vformanek on No source code available for profinet library ^{CODESYS Forge talk (Post)}
I have tried downgrading and it seems fine now. I am now on version 4.3.0.0 for the library. Mainly the PN controller caused the issue for me. Funny weird is that even the PN controller versions 4.3.1.0 and 4.3.0.0 cause the error. Version 4.2.0.0 works fine.

Post by fless on No source code available for profinet library ^{CODESYS Forge talk (Post)}
looks like you are running in a bug in the newest version 4.4.0 of the profinet library or the new library triggers a bug in your code. did you update your profinet device too? you could try to downgrade to an older version of the library. via library manager - placeholders, double click Profinet 4.4.0 in the library column and choose an older version.

Post by transmin01 on EL6751 Canopen_Manager issue ^{CODESYS Forge talk (Post)}
Hi, I have a Beckhoff EL6751 EtherCAT / CANopen gateway which fails on the Canbus when the CANopen_Manager is added. Currently no devices are connected to the EL6751. If I add a device, I get the same issue. If I add a device and connect the bus, I get the same issue. Is there something I am doing wrong? Regards Trevor

Post by laruso on Runtime device Enable/Disable procedure ^{CODESYS Forge talk (Post)}
I implemented the parts from the CAA Device Diagnosis Example.project and could use it for switching on and off, the CAN devices that were located under the CANbus and CANopen_Manager. But i can't do the same with I2C_master_test_version or devices below this one. In the example project there is only the EtherCAT Master, CANbus and CANopen_Manager, and Ethernet with devices below.

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

Post by andrax on Mux I2C ^{CODESYS Forge talk (Post)}
Hi, sorry I was not there for a long time. The TCA9548 needs terminating resistors, do you have them in? That's why I went to QWIIC, the muxboard already has them built in. If it still does not work, try it first without the muxboard. PS: Note the channel assignment. Muxboard 0 = I2C_Master 1,0,0,0,0,0,0,0 Muxboard 1 = I2C_Master 2,0,0,0,0,0,0,0 etc.

The codesys application license allows the use of up to 4 fieldbus instances (eg Modbus). I need to use more instances than that. Can I use the Modbus library instead? Does this usage require a license? Similar to other libraries such as CanOpen, Modbus TCP...

Post by timvh on Send file from codesys to...... ftp, cloud, etc ^{CODESYS Forge talk (Post)}
You can use the (open source) FTP client in Forge. This works on 64 bit systems. See: https://forge.codesys.com/prj/ftp-client/code/HEAD/tree/ As this is open, the idea is that when you use it and make improvements to the source code, that you also commit this in a branch so others can also benefit from it.

Hi Sir Kevin. May I know how you came up with this solution. Im a bit confused but I tried to put this. [SysCom] Linux.Devicefile=/dev/ttyRS48 (remember, no 5 at the end!) then set com port in codesys to 6. It also works for me but want to know where did you get this. Thank you.
