Post by narius on OPC-UA object instances preexisting in imported xml information model ^{CODESYS Forge talk (Post)}
Hi all, is it possible to use object instances that are not instantiated by codesys itself, e.g. have been defined in UA-Modeler ? When I browse the plc with UA-Expert I see those instances, but I have not seen information in codesys or the web if these are writable in codesys. So far, I am under the impression, that it is not possible, but would like to hear from others. Also, is it correct, that it is not possible to create references inside codesys ? Thanks in advance and kr

Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

An ENI file is needed for a 3rd party software solution that is being used over EtherCAT connection that emulates multiple Slave devices. This one cant be that complex, seen some legacy posts but no answers. Thank you! Bruce

Using the git scripting API, is there any way to get the file path of the project's .git/ folder?

I think this is really now "Generate EtherCAT XML" command which gives the ENI topology info.

That really depends on this third party software you want to use. It is possible that .xml file generated with "Generate EtherCAT XML" will not be recognized as valid ENI file. Anyway, "Generate EtherCAT XML" command is not available through standard menus and needs to be added via Tools->Customize and then Add Command. You'll find it under "Devices" section. If you provide more info, we might be able to help you further.

It's all good btw, learned that the runtime doesn't isolate the networks that are involved so changing the ethernet subnets away from the Wi-Fi's subnet was all I needed (maybe some config file changes helped, can't say for certain)

For general usage, these links might help you out. If you are looking at using I2C interfaces, examples from the Raspberry Pi will probably be useful, even if your board isn't a Raspberry Pi. https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_rts_serial_com.html https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_raspberry.html If you're developing your own drivers, I can't help you there, although the link you provided will help. If you drill in deeper, the I2C page for example shows function block and method usage, etc. Good luck!

Hello everyone, I have been given the task to develop I/O drivers for a custom made, Linux based board to allow for Codesys applications to run and control the hardware. I have successfully installed Codesys Control SL for ARM/Linux and tested it with a simple demo application. Now I should start interfacing the runtime to the actual hardware; I should be able to interact with 2 RS485 serial ports, a few GPIOs and an I2C port, all of which already have the corresponding /dev/ interface in the Linux system. I am having trouble understanding how it should be approached. I have found sporadic references that fail to lead to a really comprehensive documentation. For example: The store page (https://store.codesys.com/en/codesys-control-for-linux-arm-sl-1.html#options) mentions a "runtime package" that should allow "Integration of existing C code" and "Usage of local I/Os", which seems exactly what I need to interact with custom peripherals. I have found no further reference to Codesys-C interpop. The Codesys Help page for the runtime package has a page on the "Development of Drivers" (https://content.helpme-codesys.com/en/CODESYS%20Control/rtsllinuxrbpdriverdevelopment.html) that suggests to either "Implement a function block" or "Implement I/O drivers". Those in turn lead to this page (https://forge.codesys.com/drv/io-drivers/doc/Generic/) which describes briefly an XML schema to describe new devices; unfortunately, it doesn't mention what to do with such a description (i.e. how does the runtime know about it) or how it is in any way connected to the actual hardware. Could anyone give me some pointers? I should also mention I have no prior experience with Codesys, so maybe I'm missing an obvious answer.

Hi, same pb for me ! did you find a solution ? (I'm working on 2 raspberry pi ) The same project compiled for 4.8.0.0 runtime with CodeSys 3.5SP20 is working fine on one target, and on the other one, my UAexpert receives the same "BadIdentityTokenInvalid" and none is working on 4.11.0.0 either ... anybody ?

Worked for me too. Now I have to find out why I didn't need to do this on very similar systems and what the security issue is
