Hello, Is there a maximum number of Masters that can connect to a Modbus Slave that is configured in the device tree? Is this limited by the CODESYS IDE, or the manufactures hardware and CPU load? Thank you,

I am using the Innomaker USB2CAN-C device to communicate via CAN in the Windows version of CODESYS, but I am encountering error code 27E2, which indicates that the driver is not found. Could you please advise on how to proceed with the CODESYS settings?

Hi Tobthi, Do you have the eds file of the camera? I usually load first the eds file and then add the device to the Ethernet/IP scanner.

it could be due to security settings. In codesys IDE, go to device-> change run-time security policy, and click the checkbox that says "Allow anonymous login". try if this works.

Which plc is this - seems that the performance of this device is not enough. You could check the plcload in the plcshell by 'plcload'

Hi, Is the Beckhoff EL7037 supported by codesys with softmotion? Where can I find a device descriptor that includes the drive object for the EL7037?

Hi, again after spending a lot of time finding more information with no results, by chance I changed the device ID from 1 to 255 and the transmission works. Unfortunately the documentation is very very poor.

Does the OPC UA server have a generic username and password? It doesn't seem to be the same as the device username and password.

One thing you could do is create an object with the variable as field with a function and procedure to get the variable (read) and set the variable (write). These are then called from your program and the vizualization.

I found the solution. The NIC information on Deploy control SL should be defined to scan profinet devices. So I moved to the next challenge. Device is founded but still it has orange mark not green.

Hi @eschwellinger, I tried this with Modbus COM slaves. I was able to disable them (slave becomes greyed out in the device tree), but the DED.Reconfigure "eError" output shows "NOT_SUPPORTED". After this, when I tried to re-enable the slave, it did not work (device stayed greyed out in the device tree), and the DED.Reconfigure "eError" output also showed "NOT_SUPPORTED". Is there something to do about this, or the device just doesn't support reconfiguration? P.S: I tried this running locally on my computer (not in simulation mode). So of course I was not physically connected to the devices. I have two similar projects, but one of them doesn't have the Modbus_COM devices. I know I can "Exclude from build" the devices for that project, but I would really prefer not to do this if possible. I would prefer to dynamically toggle a configuration variable that would enable or disable the slaves.

Moin, falls jemand vor dem gleichen Problem liegt, hab ich inzwischen eine Lösung. Rechtsklick auf Audio, Device Profiles, dort alle anderen "Aus" und bei dem, welches benutzt werden soll, Analog Stereo-Ausgabe. Dann sollte die Audioausgabe eindeutig sein.

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.

For reference this is fixed by installing the new codesys install with a separate repository folder. Completely resolved. If anyone else sees this. I would like to know why the persistent devices repository folder does not properly retain between installs though.

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.
