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!

Post by berkdan on SMC_ReadNCFile2 is always busy

Hello, Iβm using CODESYS V3.5 SP18. When I try to use SMC_ReadNCFile2 to read the file /PlcLogic/gcode.nc, the function block's bBusy output remains TRUE indefinitely. Can you help me understand what I might be doing wrong? Here is how Iβm calling the function block. The value of strFileName is 'gcode.nc'. fbReadFile( bExecute := bExecute, sFileName := strFileName, bAbort := bCycleStop, fDefaultVel := RetainVariables.xSlowVelocity, fDefaultAccel := RetainVariables.xAcc, fDefaultDecel := RetainVariables.xDec, b3DMode := TRUE, bParenthesesAsComments := TRUE, fDefaultVelFF := RetainVariables.xFastVelocity, fDefaultAccelFF := RetainVariables.xAcc, fDefaultDecelFF := RetainVariables.xDec, ErrorID => gCNC.eErrorId, errorPos => gCNC.eErrorPos, ErrorProgramName => gCNC.eErrorProgName, bBusy => bReadFileBusy, sentences => sentencesss ); Thanks in advance for your help.

Hi Gatto, Using version 3.5.21.xx, it is no longer possible to use Modbus function blocks (I make extensive use of these FBs.)as shown in the example. https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_modbus_example.html The compiler detects one Modbus instance for each instance of the communication FB block. The example program above, although simple, reports 8 Modbus instances when compiled with the latest version. Codesys Support says that you must use fieldbus I/O mapping, but this will result in the loss of the ability to programmatically modify communication parameters. Sandro

A got a larger project but this very small example makes it clear. I have a button, and after it's clicked a lamp should flip on and stays on, and when the mouse-button is released it should stay on. When I try that in the PLC_PRG it works, but when I change it to a function block (seet attched demo proj) it isn't. I'm fairly new to PLC programming but are very experienced C# engineer, but this goes above my head...

Hello, Recently I was trying to run 6DOF robot in codesys via SMC_Trafo_ArticulatedRobot_6DOF, unfortunately no matter what parameters I tried, it always outputs InvalidConfig Error. I saw the same issue in a topic: https://forge.codesys.com/forge/talk/Motion/thread/16e1f0327f/ But if I understand correctly, the user solved it by developing his own version of this block. I wanted to know if it is a bug in the library (SM3_CNC 4.20.0.0) or am I doing something wrong? Can anyone confirm that they can use the FB without it reporing the Error? Kind regards,

Post by mubeta on Profibus DP master with EL6731 and automatic restart of slaves
CODESYS Forge
talk
(Post)
WHEREAS, I have already searched various posts and forums, where mostly there are few references and mostly geared toward integration in TwinCAT. I am looking for how to properly configure the EL6731 board as a DP master, (where I have its 3S license), with CoDeSys 3.5.19.x. I have three types of slaves, all integrated with their GSD descriptors. In the tab for the various slaves, I don't see options related to node restart on 'station return'. On the card manual, I read that for each slave I should be able to configure parameter 8000:2C: β8000:2C Restart behavior after DP fault Reserve, must be 0 BIT1 RW 0x00 (0dec)β However, in the project I see no way to configure this parameter, in any of the boards; and the arrays do not always have such an extensive size; most of the time they are only two or three words in size. The problem is that, after the hot reset of CoDeSys, the master restarts by starting all slave nodes, but if one or more get lost and go offline, there is then no automatic restart upon their return. I would need to figure out any solution, even via software, how to figure out that this one is back available and restart it.

Post by trusty-squire on How to revert to previous version library
CODESYS Forge
talk
(Post)
Hi, I'm experiencing a bug with the latest version of SoftMotion CNC library (4.17), where the 3DPath object in Visu is missing all the important properties. I've verified that a previous app I was working on with library version 4.16 did not have this issue and the issue is duplicated in that project when I update it to 4.17. I've already submitted a bug report, but for the time being I need to revert the project I'm currently working on back a revision. I've tried right clicking on the library but the option to select the version is greyed out. Can anyone help me?

Apparently my construction will not work as any of the sub-types are not be able to accept any (further) value-initiation. Ie: string_item : log_data_base := (string_value := 'test', val_type := STRING_); is not eq to (the string_value will not be assigned): string_item_2 : log_data_string := (string_value := 'test'); Because effectively for the compiler this is eq. to a "double" assignment where the compiler sees only the first assignment (my guess). string_item_2 : log_data_base := (val_type := STRING_) := (string_value := 'test'); Im not sure this should be treated as a bug, but it would surely be nice to be able to use this construction (compiler is 3.5.20.40). Anyone see any other alternative for solution (other than 4 complete STRUCTS with all fields individually defined)?

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.
