Post by tvm on multiply gives negatives ^{CODESYS Forge talk (Post)}
It's probably because you have an INT in the input to the MUL function, which will then try to output an INT as well. INT variables can only handle values of -32768 to 32767. Your value of 523000 won't fit in an INT, so it turns into an invalid number. Use a DINT. This is usually better for working with time values anyway, because time values are all 32 bit. Or if you can't, use INT_TO_DINT(gvlp.detectie_nalooptijd_s) in the input to the MUL function.

Post by micik on CAA File, how to check whether file exists or not ^{CODESYS Forge talk (Post)}
Hello, what would be the most efficient way to check whether the file exists or not. I don't want to use file.Open function, it seems like rather inefficiet operaton. I considered GetAttribute function, but this function doesn't accept filename (with path) as an input. Basically I need to check first time when program is loaded to the runtime i.e. when application is started for the first time, whether a file exists on the specific location or not.

Post by wbj0t on mobus tcp slave device. read/write holdings with 2 variables. ^{CODESYS Forge talk (Post)}
Hi there. I have an issue to read and set time for the controller. In the issue many registers described as writable by 6/16 functions, and, in this time, also(!) readable! For example: I have time registers: min, hour, day, mon, year. By specifications it is possible check time (so I need always update these varibles in loop) and set time by writing these same registers, BUT how to set, if they will immediatle updated by current time after writing? So, I need to separate one address at two variables. I have seen option mark: Overlay of the process image by the holding and input register. I understand this so: When I READ by function 3, I will get variable that connected with the same INPUT address and when I WRITE by 6/16 this will change second variable that connected with HOLDING address. BUT, this mark doesnt work, when I write 6/16 and try to get by function 3, I will get written value instead INPUT variable. So, what to do?

Post by z870623 on About CPU Loading ^{CODESYS Forge talk (Post)}
I am running a runtime environment on an ARM A35 dual-core processor (1.5GHz) and have encountered some issues. The CPU load (both CPU0 and CPU1) occasionally spikes above 50% before returning to normal, and this happens around 2-3 times per minute. At the same time, I’ve noticed that the Max Cycle Time in the Codesys monitoring screen shows much worse performance compared to the A53 (1.2GHz), with nearly double the cycle time. The optimizations I have made so far are as follows: Set the CPU to performance mode. Isolated CPUs: CPU0 is dedicated to running Linux services and the runtime itself, while CPU1 runs the EtherCAT task and the MainTask. Despite CPU1 only running these two tasks, the utilization still increases above 50%, which I find unreasonable. Additionally, I performed tests using cyclictest both without and with the runtime running. The performance is shown in the following image: From the results, I believe the CPU performance should be fine, but I am unsure why the monitoring results are not as expected. The testing outcomes should ideally be as close as possible to the cyclictest results. Does anyone have related solutions to this issue?

Hi @ph0010421 and @Ton, Is it possible to program a stopwatch to measure a system running time when it is turn on, and pause when the system is turn off. I tried your examples when stopped, the elapsed time will then be calculated, but i need the time to be continuously counting. Warmest regards,

Post by evanclegg on Digital Clock ^{CODESYS Forge talk (Post)}
To display the current time, you’ll need to retrieve it from the system clock. In CODESYS, you can use the built-in function SysTime to get the current system time. Here’s an example of how you can use it: VAR dtCurrentTime: DATE_AND_TIME; sTime: STRING(8); END_VAR dtCurrentTime := SysTime(); sTime := TIME_TO_STRING(dtCurrentTime.t); The sTime variable now contains the current time in the format “HH:MM:SSuno online".

Post by mahmutbeyaz on Create a Motion Profile ^{CODESYS Forge talk (Post)}
Dear All, I hope first to get notice and somebody answer my question. How can I create a motion profile with the axis following it (once or periodically)? As my research shows, Schineder has a UI-based (Motion Sizer) program that helps create a motion with different configurations, which is Codesys-based. I need to create a motion profile based on position, changing the speed. (i.e., 0-300mm moves with 300 mm/s, 300-400mm moves with 500 mm/s, 500-800mm moves with 1000 mm/s, and 800-0mm moves with 2000 mm/s). MC_PositionProfile does it time-based, which is not working for me as the axis may not stabilize the position in time, which may cause a big failure in the system.

Post by mostafa-beshr on implementing continuous movement in Codesys ^{CODESYS Forge talk (Post)}
Hi everyone, I’m working on implementing continuous movement in Codesys, but I've run into some trouble. I've tried using ALL SM3 Basic and SML without success. I’m specifically looking for a library that supports continuous updates and can fetch values from a server in real time. Does anyone know of a library or approach that fits these requirements? Any advice or suggestions would be greatly appreciated! i read plcopen documentaion as well as codesys Thank you!

Hi, i am interested in this thread and have tried a couple of the above examples in to determine remote webvisu access. I am having trouble getting the lastusage variable to refresh during runtime? It seems to only log the last usage at initialisation and that is it? how do i gain ongoing access to the time variable as the code is running? Thankyou.

Hi, thanks for the fast response :) Yes I Have a .err file. Sorry I forgot to upload it. It is a binary file though... "Runtime goes in exception before the shutdown ?" I think it goes into exception at the same time as the power is lost...

Normally it works if I ad in CODESYSControl.cfg: [SysFile] ForceIecFilePath=0 (This told me codesys last time) I try to use the placeholders but without success.
