Hi, I got good results with SMC_NCDecoder, SMC_CheckVelocities, etc. in a freewheeling task with lower priority (higher number). Still takes some time but I'm using many variables and loops in my g-code and more preprocessing like SMC_SmoothPath, SMC_LimitDynamics, SMC_CheckForLimits. PS: your buffer size seems a bit high for 34 lines of g-code

Hi I try to get korean texts out of a textlist. For that I want to use DynamicTextGetTextW, but I am a little confused how it is supposed to work. The function returns POINTER TO STRING, but how do I get WSTRING? I succesfully used DynamicTextGetText with classical Strings. Thanks in advance!

If the PLC is equieped with a USB socket it's possible to copy the user management file via IEC code to a USB stick and restore it at the new plc. The file is located there: /PlcLogic/visu/app_visuusermgmtdb.csv I use this to reset the user management to default in case of the customer has changed passwords and lost it.

I believe it should be available. It may be the case, that your device does not support the alarm configuration. Some smaller PLCs sometimes do not support it. You can try changing to a different device, like a Codesys Control Win, in your project, and see if then allows you to add the alarm configuration.

You could create a DUT of the Type Union and add an array of 2 bytes + an Int. Then write the byte values in the array of the Union and read the Int. Or VAR iInt : INT; byHigh : BYTE := 2#1111_1111; byLow : BYTE := 2#1111_1111; END_VAR iInt := TO_INT(byHigh*16#100 + byLow);

Really not clear what you are trying to do, but isn't a Struct enough? So add an object of the type DUT to the Application. Then create a structure TYPE ST_Sensor : STRUCT sName : STRING; uiNumber : UINT; END_STRUCT END_TYPE Then in you application add an instance of this Structure stSensor1 : ST_Sensor := (sName := 'my sensor', uiNumber := 1); or use it like this stSensor1.sName := 'my sensor';

Initially I had the same problem in CoDeSys when selecting a newly installed TTF font, while CoDeSys was running. I solved it by closing Codesys and running it again to restart the initialization process. After that, using the new font did not pop up errors. I also had cases with files that had a ttf extension, but were actually not TrueType.

Hi, the option "Support client animations and overlay of native elements" needs a very powerful graphics accelerator in the system. I'm using the Pixsys srl "TC series" HMI with the code "P3" (so a 4+4 cores CPU) that runs very well also with this option active.

I took a look at your project. First of all, a Raspbery Pi4 is installed. You must use the GPIOs_A_B(GPIOs B+/Pi2). The error ULINT can't be set to IDINT.... with your project as well. If I change your project to ‘CODESYS_Control_for_Raspberry_Pi_SL’ the error is gone.

It should come by default on a normal install of Codesys 2.3, but it's a bit hidden: Like for any other library, go to Resources > library Manager > Right click on list of libraries > Additional library. On the browser that opens, instead of looking in the default folder, use the dropdown menu at the bottom to change the folder (SysLibMem should be on the 3rd folder).

@TimvH, Thank you, i think this way i can seperate the complete string to characters. Next part of the topic is converting the characters to an ASCII code. Is there an standerd function in Codesys for this? I alredy searched a few hours for it on the internet. no succes.

Post by sturmghost on Initialization of visualization variables and cyclic code execution
CODESYS Forge
talk
(Post)
I'm looking for a smart and short way to implement initialization of visualization variables depending on the visualization input. For an easy example consider a rectangle which rests at XPos := 0 when the input state is false and at XPos := 50 when the input state is true. My visualization variables look like this: VAR_IN_OUT State : BOOL; END_VAR VAR XPos : INT; END_VAR I put this rectangle via a visualization frame element into another visualization and link a frame reference variable with the state to it. If the variable is true, the rectangle should rest at XPos := 50 and false at XPos := 0 at visualization init but how should I assign the 50 or 0 to the internal visualization variable XPos? I would need some init-methode for the visualization but I dont want a global init-method for such tasks. I want to do it inside of the visualization element but I can't see any solution for this? It would be good to be able to define ST-code within the visualization element which runs cyclic at each VISU_TASK task-cycle then I could just check the input state and change the XPos accordingly. Does someone have a solution?

Hi! I´ll try to get this thread going again as i´m having simliar problems. Right now i get a red triangle on my connected devices (i´m testing with a BME280 sensor and a PCA9685 resvo driver). The TCA9548 have the green symbol beside it. On the "red" devices i get that the bus is not running. I have tried to either run it using the parent bus cycle setting or creating a new freewheeling task prio 1 but nothing helps. I have compared my settings to the settings from the example from the MUX package and i have read (i think) every thread in forge that could be of interest. EDIT: The ic2detect only shows the mux (70-70) and the servo drive (70-76) so i´ll look in to if i managed to burn the 280-sensor while soldering). Another question regarding the 280 sensor. I have a sensor GY-BM E/P 280 that should record humidity and temperatur. Could this be a problem with the library? Does anyone have an idea of what i might be doing wrong? I have some experience from Codesys but not much so this could be an easy one. All suggestions are welcome. I tried to upload the project archive but it did not work. Should i upload the export or how could i show you my horrible project? Best, Martin

Hi all, i am encounter a mystery problem with a build with rexroth drives at my work. At my company we are make a machine with two Rexroth Indradrives . The two drives are goes by ethercat protocol . To be more specific i am going from my plc to the Beckoff El1100 coupler and after to the first drive and from the first drive to the second. The second drive works with no problem but the first(motor) sometimes without any pattern start to make a mysterious noise like stop and suddenly goes on again. If i couldn't hear the noise from the motor i couldn't Imagine that this happen. After a lot of research i see that sometime i have some strange zeros from the drive to the plc? Really i am in a deadlock and I don't know how to continue. From the other side the values on the other drive(second)are stable . The problem maybe: https://youtube.com/shorts/g7PCFLUaDUI?si=eiq0F2IzhQZax2e2

Post by arundara on Variable Sync Issue In Soft Plc Redundancy

Hello, I was trying to create a redundancy POC for our application where we read data from few modbus tcp devices. As there is a limitaion that modbus tcp device support only for single master device, we wanted to test how the variable sync happens in redundancy mode. For that i have used the redundancy sample code added a variable "b" under a condition. What i observed was while active controller is running, if passive controller is powerup, passive controller is able to sync all the data configured for redundacny. But after that the variable data which resided under a condition is not synching from active to passive controller. I have attached the image where i have highlighter the variable. Can some help me to understand how redundacny work in codesys soft plc and if there is a solution to sync variable which are under condition, please explain the same or suggestion to achieve the same. Hardware - Raspberry Pi (2 qty) Redundancy licence used - yes in both controllers. Codesys runtime - 4.9.0.0 Codesys software version - V3.5 SP19 if i have posted this question in wrong section, please do let me know in whcih section i have to post this question.

Post by user3000 on Can't find an Extended Pulse Timer (TP and LTP)
CODESYS Forge
talk
(Post)
Hello, For my program I need an extended pulse timer, which can be referred to as a retriggerable pulse timer. Where every rising edge of the input resets the elapsed time zero, extending the lenght of the output pulse. The Codesys pulse timer (TP) is a one-shot timer and only resets the elapsed time with the falling edge of the input. There is also a pulse timer (LTP) in codesys, but in my simulation it was also functioning as a one-shot even though the description sounds like LTP should be retriggerable. I have uploaded some timing plots from another PLC program for reference. I am looking for a timer equivalent to the "TEP" diagram. Is there an Extended Pulse Timer in Codesys? Maybe there is a way to manipulate the input so it resets the elapsed time outside the function block?
