Post by kporter on Codesys EtherCAT Driver (CmpEt1000MPD) can't set MAC address ^{CODESYS Forge talk (Post)}
EtherCAT is a point-to-point protocol so it doesn't need a unique MAC address. It would be very useful to set the MAC address to 020000000000, the standard address for this kind of application. (The important bit is the 02 at the start of the address, which means locally-administered MAC.) The stock Windows driver can do this for my i210 card. But the CODESYS CmpEt1000MPD driver cannot. The image shows the setting with the Windows driver. If I set all my customers' cards to this address, then I don't need to deal with this when deploying my application. A simple PowerShell script can be used to set the MAC address once when the NIC is installed and the driver is changed.

Post by pernockham on Unable to deploy "Control for Linux SL 4.18.0.0" ^{CODESYS Forge talk (Post)}
And the strange thing for me is that if i connect with an older IDE version (where I only have 4.17.0.0 installed) I can see both "CODESYS Control for Linux SL" and "CODESYS Edge Gateway for linux". And that I loose (both presence and possibility to update) the first option (Control SL) if i let the updater install "Control for linux SL" vers. 4.18.0.0 or later. (Note that runtime 4.17.0.0 is installed and it is running and I can login to that system, but no apparent option available to update it to 4.19.0.0). Attached print screen where I connected the "deploy sl tool" to the same system, where the upper (IDE) one has 4.19.0.0 installed, while the lower one has 4.17.0.0 installed..

Post by yannickasselin on Question about Demo License limitations for Modbus TCP communication and Fieldbus Instances ^{CODESYS Forge talk (Post)}
As far as I know, there is no other limitations than the 2 hours limit. The demo mode should be plenty enough for testing purposes. Regarding instances. In the device tree, 1 master = 1 instance, no matter how many slaves the master is communicating with. But it is also possible that your Codesys runtime act as a slave. In this case, each slave in the device tree is one instance. You can also use the license metric tool in the IDE. This will tell you exactly how many instances you have in your project. https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_edt_device_licensed_software_metrics.html

Post by gseidel on Absolute movement controlled by an external encoder. ^{CODESYS Forge talk (Post)}
Hi polyautomacao, basically, there are two ways to approach this. My first choice would be to check whether your servo drives supports an external encoder, connect the encoder to the servo and configure the servo accordingly. In this case, you would not need to change anything in the CODESYS application. If that is not an option, you could use SM_DrivePosControl, a drive that closes the position loop in the PLC, and feed it with the external encoder positions. See (0). You can switch your servo drive to velocity control mode (SMC_SetControllerMode) and use SMC_FollowVelocity to apply the fSetVelocity of the SM_DrivePosControl to your servo. The MC_MoveAbsolute can then be performed on the SC_DrivePosControl Hope that helps. (0) https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_example_poscontrol.html Best regards, Georg

Post by pruwetbe on Profinet IO-link master - IODD files ^{CODESYS Forge talk (Post)}
Hello, we have the same problem here. Our configuration in the following: Codesys V3.5 SP19 running on Exor Exware700Q Profinet network connected on Eth1 IOLink Master Turck TBEN-S2-4IOL version 3.5.9.0 IOLink sensors E+H & Sick (Pressure, T°) We installed the codesys IO link package and have the codesys IO Link SL licence activated (on a dongle) Our problem is the following: we got the IODD files from E+H & Sick we add the devices in the codesys device repository with success They appear in the devices tree under IODD branch We added the TBEN IOLink master under the Profinet IO . The IO link master are ok and display online. The IO-Link SL package datasheet indicate that there would be a way to scan the IOLink device from the network but we did not find any way to trigger this scan. (we expect to get this from a right click on each IO-Link Master module but the only possibility there is "Plug device") When clicking on Plug Device, we get a browse window with profinet IO modules. The IODD devices are not there so we cannot select them. But other devices for other brands are available and can be plugged. Our question are : 1) how do we update the Profinet IO Module catalogue in order to be able to plug the E+H & Sick Sensors that we have to work with? 2) how do we activate the Scan IOLlink device that is supposed to be included in the Codesys IO-link package? 3) where can we find the manual explaining how to use this package?

Post by fmon on Modbus TCP client reconnection problem ^{CODESYS Forge talk (Post)}
Hello, I am using codesys Modbus TCP client (4.4.0.0) to communicate with a python modbus server (package pyModbusTCP). I first start my python server on the distant machine. After a fresh codesys compilation, a plc connection/transfer and a PLC run, the modbus connection is OK. Every time in this context the connection is created correctly. When I shut down the server, the modbus connection falls, that is normal. When I restart the python server, impossible to recreate the modbus connexion. With the client autoreconnection, I see on my server that the client tries to connect but unsuccesfully. I have the following message : DEBUG:pyModbusTCP.server:accept new connection from ClientInfo(address='192.168.1.20', port=33476) DEBUG:pyModbusTCP.server:Exception during request handling: NetworkError('recv return null') I tried to stop the codesys client and to restart it with these commands : Modbus_TCP_Client.xStop := True; // Or False Modbus_TCP_Client.Enable := True; // Or False Modbus_TCP_Server.Enable := True; // Or False I tried to confirm the error manually to force reconnection with: Modbus_TCP_Server_Motors.xConfirmError := TRUE; I tried also this command to STOP/RESET/START client and server (codesys side) but nothing happens : status_client := Modbus_TCP_Client.SetCommunicationState(eRequestedState := DED.DEVICE_TRANSITION_STATE.STOP); // .RESET & .START The answer of this function when executed is "status_client = NOT_SUPPORTED". Is it normal ? It seems that is a socket problem, but I do not understand if it is on the client or server side. I tried a modbus simulator called "ananas.exe" and the result is the same. Impossible to get a modbus client reconnection. What is different at the first client connection and at a reconnection attempt ? Thanks for your help

Post by elektron785 on GPIO mit Codesys Virtual Control for Linux ARM64 SL ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich möchte an einem Entwicklungsboard auf dem der i.MX 8M Plus von NXP aufgesteckt ist die vier zur Verfügung gestellten GPIOs als Ausgänge verwenden. Ich habe mir dazu die Readme-Datei des GPIO-Beispiels von "C:\Program Files\CODESYS 3.5.20.40\CODESYS\CODESYS Control SL Extension Package\4.14.0.0\Examples\GPIO" angeschaut Die Übersicht der verfügbaren GPIOs sieht folgendermaßen aus - wobei ich das auf die reduziert habe, die für mich von Interesse sind: gpiochip0: GPIOs 0-31, parent: platform/30200000.gpio, 30200000.gpio: gpio-0 (SODIMM206 ) gpio-1 (SODIMM208 ) gpio-2 ( ) gpio-3 ( ) gpio-4 ( |sd-vsel ) out hi gpio-5 (SODIMM210 ) gpio-6 (SODIMM212 ) gpio-7 (SODIMM216 ) gpio-8 (SODIMM218 ) gpio-9 ( ) gpio-10 ( ) gpio-11 (SODIMM16 ) gpio-12 (SODIMM155 |regulator-usb1-vbus ) out lo gpio-13 (SODIMM157 ) gpio-14 (SODIMM185 |regulator-usb2-vbus ) out hi gpio-15 (SODIMM91 )** Füge ich nun das GPIO (1 Bit)-Gerät in meinem Codesys-Programm hinzu funktioniert der Bus solange bis ich die Richtung in den GPIO-Parametern von "not used" auf "Output" stelle (siehe Bild gpio_parameter). Dann funktioniert nach Download der Bus nicht mehr. Gibt es noch eine andere Möglichkeit das zu steuern oder muss ich noch Einstellungen tätigen? Für die Zeile mit dem echo (export/unexport) aus dem Beispiel fehlen mir trotz sudo die Zugriffsrechte. "The Kernel Linux has deprecated GPIO user space SysFS. However, the kernel config CONFIGGPIOSYSFS is still enabled on Toradex's BSP to support customers using it in their legacy applications. You can check the configuration by running zcat /proc/config.gz | grep CONFIGGPIOSYSFS. For GPIO access from userspace, the new char device API, also known as libgpiod, must be used." Dies steht in der Verwendung der GPIOs - eine Ausführung des zcat-Kommandos liefert ein =y zurück.

Post by gunstr on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
Thank you very much for the quick answer! The RPi hw were delivered last week so it's probably a resent version. I found an old scrapped board (2 years or so) with a broken GPIO that I tested with the same SD card image and with that board Codeys can run for the full 2h demo period without issues. Then I went back the the new board to test the 4.17.0.0 release but the installation fails... [INFORMATION] Standard output: create and install daemon [INFORMATION] Standard output: codesyscontrol started [WARNING] Unable to detect Raspberry Pi Architecture. Setting armv6l as default, you can change this through the settings panel. [INFORMATION] Standard output: codesyscontrol stopped [ERROR] Expected exit value of command failed: expected 0, received 1 [WARNING] Error setting the Raspberry Pi Architecture [ERROR] Error installing codesyscontrol Do you have any idea what could be the reason? I'm using an OS image including Python drivers for LCD and some I/O:s from last year to keep things stable, but also after upgrading with sudo apt update && sudo apt upgrade I still get the same error Reverting back to 4.15.00 works fine: [INFORMATION] Standard output: create and install daemon [INFORMATION] Standard output: codesysedge started [INFORMATION] Successfully installed codesyscontrol [INFORMATION] Successfully started CODESYS Edge Gateway for Linux [INFORMATION] Successfully started CODESYS Control for Raspberry Pi SL but as before the Codesys services stops after 30 seconds. And I noticed that the Codesys control stops and is not reachable also if I have no application loaded.

Hello good morning everyone I would like to ask a question, is it possible to directly connect a device that only contains modbus RTU communication through an R-45 connector, directly to the PC? Or would you need an intermediate device to achieve communication? It would be of great help to me because I cannot achieve communication between the Codesys simulator plc and a Fuji Frenic mini VFD, please help me if anyone has had the same experience. Thank you so much

Post by transmin01 on CANbus issue ^{CODESYS Forge talk (Post)}
Update: This initial issue was when using a Linux target PLC. Since then I have created a Win10 target PC and the Codesys software reported an issue associated with the device version (see attached). I am assuming this is an incompatibility with the xml file from the manufacturer and the firmware version on the module and I am chasing this up with Beckhoff. Question is, why would this not report with a Linux target?

Post by timvh on CANbus issue ^{CODESYS Forge talk (Post)}
On a PC with the Control Win, this is probably related to the fact that the CAN drivers are not loaded. Go to the folder where your Control Win Configuration file is: - E.g. C:\ProgramData\CODESYS\CODESYSControlWinV3x64\E1FA7ABE - Open the CODESYSControl.cfg - Remove the semi-colon in front of the CAN driver you want to use (section ComponentManager). - Set the component ID to the next number in the list (e.g. Component.8) - Save this file and restart the Control Win.

Post by eschwellinger on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
you need at them moment a download once (for the configuration files generated including addresses) then stop the plc - exchange the persistence file ( without the config file) This will be improved to 3.5.18.6 and 3.5.20.0. (possible then to generate offline bootproject including full persistenmanager files) - this is if you have not 100% the same bootapplication on the devices. In case you copy the whole Application (PLCLogic) directory it should work out of the box - but only with 100% same bootprojects as mentioned above. By the CODESYS Automation Server would help solve this too.
