By using the CAA FILE library (FB FILE.Open) (raspberry pi, codesys 3.5.19.0) I always get the error FILE_OPERATION_DENIED The file exist, it has r/w/x access and path is correct... Some idea to fix it?

Are you using the Wago Runtime - please check the version information on scan. Either 6.x.x.x or CODESYS 4.x x.x SL Runtime- and always check the plclogger in such cases.

This worked for me. I had four identical PLC's. Three of them worked just fine with 255.255.255.255 as the broadcasting address but the 4th would not update the variables. Changed it to 192.168.x.255 and everything worked.

Post by alimans on Hex string ^{CODESYS Forge talk (Post)}
Hi kdkwhite, for Word you still can use suggested code by using a union structure and crack down your Word to two byte as bellow: TYPE CrackWordToByte : UNION InWord : WORD; OutBytes : ARRAY [0..1] OF BYTE; END_UNION END_TYPE then define your variable as this type: udInput : CrackWordToByte; now assign your Word variable input to InWord and send OutBytes[x] to the mentioned method: udInput.InWord := WordVariableInput; Input := udInput.OutBytes[x]; Regarding your question about the code: actually 48 is ascii code of "0" and while 65 is the ascii code of "A" so in above code 55 + 10 would be 65.

Post by jeroen on Ramp function ^{CODESYS Forge talk (Post)}
Hi, Found a nice ramp function in the OSCAT lib (FT_RMP), but is there a nice way to 'set' the output to the current input as form of a reset. The reason for this, is that I want to set up a ramp for a pressure control input that should have x Bar/sec linear rise input. The only option (or code it by hand) I found is this OSCAT FB. Any other options? Just need to increase a value by x Bar/sec from let's say 250Bar (as start) to end 1500Bar. The Oscat ramp will always start at 0 when enable is off (FT_RMP.Rmp := FALSE)

I recognized that I have to start the two services "/etc/init.d/codemeter" and "/etc/init.d/codemeter-webadmin" in the docker container as well. If I do so, then the command "cmu -x" returns root@sensoredge-field-netfield-produktmanagment:/# cmu -x cmu - CodeMeter Universal Support Tool. Version 7.60c of 2023-Aug-09 (Build 5625) for Linux/ARMHF 64-Bit Copyright (C) 2007-2023 by WIBU-SYSTEMS AG. All rights reserved. So this time there is no indication any more that "Codemeter is not running". But still we are getting the error when using the license manager in CODESYS development system.

Post by peterned on CNC - system goes to X=0 Y=0 before CNC file execution starts, how to avoid that? ^{CODESYS Forge talk (Post)}
Hi, I have a XY system and use a CNC file to move it. Everything works OK, except for the following: when CNC execution starts, the system rushes at high speed to (X=0, Y=0) point, and only then goes to the first line of the CNC file. If one of the axes is near 0, the system jumps and immediately stops with an error. In the CNC file settings (screenshot attached) I specified low default values for speed/acceleration and a start position different from 0,0 - but all that is ignored. Any idea how to avoid that move to 0,0 ? Thanks.

Post by askic on Generate FBs from source ^{CODESYS Forge talk (Post)}
Hello, I'm coming from Siemens (TIA) world and currently learning Codesys. I'd like to know if there is an option to add external txt file with ST code for creation of a function block and then use this file as a source file from which FB will be generated? For example, in TIA, there is an option add external source file to the project structure and then use option "Generate blocks from source". This would create a FB. Does Codesys have something similar? This external source file would look like this: FUNCTION_BLOCK Scaling VAR_INPUT x, k, n : REAL; END_VAR VAR_OUTPUT y : REAL; END_VAR VAR END_VAR y := k*x+n; END_FUNCTION_BLOCK

As far as I know I can only upload client certificates to the PLC and move it to "Trusted", "Untrusted" and "Quarantined". Same question is on sps-forum.de

Assume I have a rectangle named rec1 from which I want to use the coordinates of the upper left corner. Is there a way to links these X and Y values from the properties to an integer defined in the main program? Note that I just want to use them and not change any of these coordinates in the program.

One workaround is to create a second application which is started after the rested of the main application. The second application starts the main application after time x and is rest after done start of the main application. No problems during the fieldbus re-start by this workaround.

Post by jackbrady on Function Blocks and arrays of function blocks ^{CODESYS Forge talk (Post)}
Hello, I am new to Codesys and PLC programming in general (please go easy ha!) I'm not looking for code to be written for me just some help and pointing in the right direction. I am writing some code to send commands to a relay based on input values (to put it simply). Quite basic stuff. I have wrote a function block that takes a global variable (Open_command:BOOL) and outputs to another global variable (Opened : BOOL). The function block is simulating a device so I'll eventually get the globals from that. I now need to create multiple versions of this function block/ device (lets say 100) but I need each iteration of that function block to reference it's own relevant global variable. I think that the best way of doing this would be to use arrays, although I could be wrong. I am aware that for up to 100 instances I could very well manually assign everything but that seems rather time consuming and I want a fancier way of doing it. Here is a very basic example of what I am looking to do, please note I have not written this in proper code it's just to show what I mean. Global Variables V[0-100] int Open_command [0-100] Bool Opened [0-100] Bool Function Block var input x : BOOL Var output y : BOOL if x then y = TRUE ELSE y = FALSE The input to my function block will be Open_command, output will be Opened Example code. If V[x] > 10 then Open_command [x] = TRUE ELSE Open_command [x] = FALSE (So when V1 goes above 10 I need Open_command1 = TRUE therefore initiating FB1 output. V2 > 10, open_command2 = True > FB2 output V3 > 10, open_command3 = True > FB3 output ... ... ) What I can't seem to figure out is how to tie all this together, I have read through the codesys documentation and if anything it has confused me more! ha. Apologies for the poorly written post but hopefully you understand what I am trying to get at. Thanks, Jack

Hi TK_Jenssen did you found a solution I am setting up the samelike gantry only with two z-axes which are mounted on fix position with an X axes between the two z-axes. The movement and position of both z-axes must be very well aligned and calibrated. Maybe also to be adjusted by programming. Can you sent an example of your solution?

Post by durstloescher on Codesys Input Detector ^{CODESYS Forge talk (Post)}
Good morning, I am currently working on implementing a display dimmer. I want the display to dim after X minutes. This works so far. The implementation is done via the Linux subsystem, to which a command is sent to dim the display. However, my problem is resetting the timer when input is received. I want the dimming timer to be reset with each click/touch. Unfortunately, I can't find a suitable solution for this. Are there any ways to do this? Codesys v3.5 SP19 Patch 2

Post by eschwellinger on License problem gateway ^{CODESYS Forge talk (Post)}
I just try to help. Anyway it is a big difference if a Store SL runtime or an oem plc and licence is used. These licenses need to be activated on plc side - so you have dependencies to the version (CODESYS and Runtime Version) Did you ever ask Epis out for this situation? They should know which license fit to their device. Even they should know if the device is capable for Softmotion and see the requiremnts in the CODESYS store: Runtime 4.9.0.0 - how should this work with Epis 3.5.16.x? Anyway refund is not a problem.

Post by gseidel on CNC - system goes to X=0 Y=0 before CNC file execution starts, how to avoid that? ^{CODESYS Forge talk (Post)}
Hi peterned, the start position given in the CNC properties is only used if you use the compile mode OutQueue. With compile mode SMC_CNC_REF, you need to provide the start position in the IEC application. The function block SMC_NCInterpreter has an input piStartPosition. You can initialize it with the output of the forward kinematic transormation FB for your machine. In your case probably SMC_TRAFOF_Gantry2. Best regards, Georg

Hello forum Does anyone have experience with optimally adjusting the position and size of the visualization elements? For us, the adjustment on the x-axis works in Codesys 3.5 SP20 with (Container.Width - Visu.Width). However, the y-axis is not affected with (Container.Height - Visu.Height). We implemented this according to the example from Codesys "Optimally adjust position and size" and had no success. Thank you very much for your help.

Post by trusty-squire on Display Units/Scale on Path3D visualization ^{CODESYS Forge talk (Post)}
Hi, Is it possible to display the units along the X,Y axis of the Path3D element? It correctly shows the CNC path to be followed, but there's no indication of scale or size of what's being displayed. I looked at the documentation and my first inclination is that this is not possible, and the option option would be to somehow recreate the Path3D functionality into the XY Chart visu element - which is not ideal. Any suggestions or pointers would be appreciated!
