Post by mondinmr on Jitter problems on imx8 ^{CODESYS Forge talk (Post)}
SOLVED!!! In this imx8 max_cstate=1 in kernel boot parameters is not working! We found a workaround: #include <stdio.h> #include <fcntl.h> #include <unistd.h> #include <stdint.h> int main(void) { int fd; uint32_t value = 0; fd = open("/dev/cpu_dma_latency", O_WRONLY); if (fd < 0) { perror("Error opening /dev/cpu_dma_latency"); return 1; } if (write(fd, &value, sizeof(value)) != sizeof(value)) { perror("Error writing to /dev/cpu_dma_latency"); close(fd); return 1; } while (1) { pause(); } } This simple code launched before CODESYS do the same work! Now jitter is identical as measured by cyclictest!

Post by simotion on Online view : code is scanned ^{CODESYS Forge talk (Post)}
If I do online monitoring of code in f.i. a function block, I cannot see if the function block is called or not. In software from other vendors you normally have an indication if the online code you are looking on is scanned at that moment or not. Is there a way in Codesys to determine in the online view if (parts) of the code are scanned or not? Thanks

Hello @eschwellinger, Why not using one of those 2 folders: C:\ProgramData\CODESYS C:\Users\Public\Documents\CODESYS The main reason is depending on the company and the user right, the end user may not have the access to use those folders. Also having a non version dependent folder may help if the end user uninstall a previous version and forgot all its sample project where in this previous version installation. Thanks.

Post by voffi on Converting UINT into bytes and converting 2Bytes into UINT ^{CODESYS Forge talk (Post)}
There are some ways. One is to use SHR and SHL and it depends on your byte order in the data array. For Motorola byte order: PROGRAM PLC_PRG VAR u : UINT; byte_array_in : ARRAY [1..8] OF BYTE := [16#11, 16#12, 16#13, 16#14, 16#15, 16#16, 16#17]; byte_array_out : ARRAY [1..8] OF BYTE; END_VAR u := SHL(TO_UINT(byte_array_in[2]), 8) + TO_UINT(byte_array_in[1]); byte_array_out[1] := TO_BYTE(u); byte_array_out[2] := TO_BYTE(SHR(u, 8)); If it's Intel byte order just change 1 and 2 in the array indexes.

There seem to be problems with the latest version of raspberry pi os 64bit (I used the lite version). The codesys control runtime crashes after a few seconds. The same runtime works on the raspberry pi image from 2023-10-10 When starting the runtime from the commandline, i get the following error: ooops... this runtime was build for RASPBERRYPI. Hardware version or firmware version not supported! (and yes, I'm running this on a raspberry pi :-)

Post by mputaggio on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hello, We encountered the same issues on both recipe library versions 4.2.0.0 and the newest 4.3.0.0. The Arrays of structs get saved correctly but loading them restores only some indexes, while others get lost or completely wrong. We have been using the same recipes for the last two years on recipe manager vers. 3.5.17 withoud issues. There also seems to be a different behaviour in vers. 4.3.0.0 but it's still incorrectly loading the recipes. Did you find any workaround or solution? Codesys version used: 3.5.19.50

Post by andrax on Mux I2C ^{CODESYS Forge talk (Post)}
the TCA9548a does not work in Codesys. In Pyton this is only queried once and in Codesys cyclically. Of course you can also insert a terminating resistor in each port, then you should have no problems. I use this one: https://botland.de/8-bit-multiplexer/12723-qwiic-mux-breakout-8-kanal-modul-mit-i2c-multiplexer-tca9548a-sparkfun-bob-16784-5904422341428.html You can simply set the library to the latest version. You do not need Oscat. Do you need an example project for the BMP280?

Hello, I couldn't figure what/where the issue was, so I deleted everything from automation server and reinstalled the edge gateway and did the process again. It worked for about a month and then it stopped working again. It presents the same symptom, edge gateway is online but I can't connect to the PLC. Any idea of what could be the issue? Thank you!

Post by sturmghost on Visualization using methods and cyclic ST-calls ^{CODESYS Forge talk (Post)}
I found a way to do it: You can use, for example, the text variable property of any visualization element and call a function in it. Example: Write a test POU as a function (FUN), like MyTestFun which need a boolean Variable as an input value. Now write into the text variable property: MyTestFun(bBooleanValue) Thats it. The function is called at each visu_task cycle.

Post by wiresplus on Cannot get INT_TO_TIME working ^{CODESYS Forge talk (Post)}
Hello, I have a simple TON timer. It is watching prime loss for a pump. The operator can set the delay via the HMI, it is an integer (seconds) As the TON uses milliseconds, we then multiply the entry by 1000 to get seconds. Seems simple, but... VAR PrimeTimer : TON; primetime : INT; END_VAR PrimeTimer(in:=State>0 AND FlowRate<MinimumFlow,pt:=INT_TO_TIME(primetime *1000)); For an entered 15 seconds (VAR primetime:=15;) the timer reads 49d17h2m26s760ms !!!! What am I doing wrong?

Hello, I need to execute "sudo" commands via CoDeSys 3.5 SP 19 P5 using the "SysProcessExecuteCommand2" function. Commands without sudo are no problem, but as soon as sudo is used in a .sh or a single command, it does not work. Command=AllowAll is entered under "SysProcess" in CODESYSControl.cfg. Nevertheless it does not work. Does anyone know what the problem could be? Greetings, Thomas

I have not gotten to the bottom of this yet no. I have double check that the variables are correct linked. When online with the program I can see the button and rung going true for the move instruction, yet it does not change. Forcing the bit in the program does change the value in Groov View. I am kind of at a loss here, especially since the other POU(For the pumps) does the same thing fine.

Post by thomasrohnerch on Color Change for Symbols not working ^{CODESYS Forge talk (Post)}
I have some Symbols from the Visualization Toolbox on my Target Visu on the Computer. I tried many Symbols, mainly Arrows. I'm able to control the visibility with condition e.g. "GVL.actual_testvalues.speed <= 0" But I can't do "Toggle color" with boolean GVL.b_toggle_color. Neither "TRUE" nor "FALSE" does change anything. Is this a known issue? I'm using CODESYS V3.5 SP19 Patch 5 + (64-bit). See attached file with more Version-Info. I'm currently using Style 6, Gradient axial 2, 3.5.12.0. I had the same issue with Default 3.5.16.0.

Post by otdeveloper on IEC 61499 ^{CODESYS Forge talk (Post)}
It is being worked on by many companies and its even-driven function blocks seem like a natural evolution of the object oriented industrial programming I have seen Gary Pratt (author of the Book of CODESYS and much more) so expertly implement and explain. I would expect CODESYS to have this front and center on their sights and, if they do not, I would be very interested in learning why.

IEC 61499 is probably something more complex than what you have correctly said so the prospects are interesting but we cannot ignore that it came out almost 20 years ago and has not won many hearts. I started to explore this world with a PLCnext controller because I love these devices based on RT Linux and Codesys is somehow usable with them but I have made little progress and I feel like inside a nutshell in the middle of the sea ;-) Gary's voluminous and precious book is always on my desk...

Post by martinla on New Codesys Library Dependencies ^{CODESYS Forge talk (Post)}
When creating a new Codesys library, I am getting 2 errors for missing libraries. I can see that I am using newer versions of these in the library manager (3.5.17.0 and 3.5.19.0 opposed to 3.5.8.0 and 3.5.7.0 stated in the errors). IDE Version is V3.5 SP19 Patch 6. The "Download missing libraries..." button in Messages list is not doing anything. Why is it looking for older versions of these libraries? Can this be fixed by using the newer versions? How can I download & install the older version of these libraries?
