Post by eschwellinger on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
At the moment there are some changes on PI OS, which lead to problems with the PI5 an Pi runtime. I would use Arm SL or Arm 64 SL as runtime depending on which OS you have installed. just use the CODESYS Installer and deploy the the Arm runtime.

Post by marks on Regarding trend storage access error ^{CODESYS Forge talk (Post)}
I had this problem when running the application as a Simulation. When I wrote it to the Pi all worked as expected. If this isn't the case for you, we've seen some issues with sqlite on the Pi's - so reset Origin and re-download may help in that case. Good luck, Mark

Hello just to give more feedback the error I get is "ERROR_UNKNOWN :represents raw value of 5110" in File.DirOpen. The xDone never gets true, and I never get the listing of files (csv files in this case). In the hDir i get the value of 0 for a DWord!?

Post by dkugler on Converting hex bytes to float ^{CODESYS Forge talk (Post)}
have a look at UNIONs. With a union you are able to write single bytes to the same adress area which belongs to a float variable at the same time. I like to do a lot of convertions belonging to interfaces and fieldbus in this way, f.eg. word / byte swapping etc.

Post by oymyakon on Modbus Lockup ^{CODESYS Forge talk (Post)}
Hi i have a project where i am communicating with many modbus devices using TCP to serial. This is all working extremely well except when i turn one of the remote devices off. If i leave the auto reconnect on it still doesn't talk to the rmianing devices and if i turn Auto reconnect off it locks up. Any help would be appreciated. Paul.

Post by maldus512 on How to adapt Codesys Control SL to custom board ^{CODESYS Forge talk (Post)}
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.

Post by tk096 on gear over gear (2 masters,1 slave) - how to do it? ^{CODESYS Forge talk (Post)}
Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html

When I use the FUNCTION_BLOCK ModbusChannel I have to sepcify the integer iChannelIndex It can easily go wrong if one has many channels. It would be better if one could use the name. Is that possible? Attached a snippet of the channel name and the channel index to the left.
