Post by bruceae on Special Characters CODESYS Forge talk (Post)
Hello, I am fairly new to the codesys environment. Is there a reference chart that I can look at in order to write special character in a string? The Special characters that I need to inclue inside the string are as follows; Null Bell Carriage Return I have a TCP_Write command that I am sending to an external device. In order for that device to function properly it needs to see the string with the null and bell characters as the header, followed by the desired command, terminated with the carriage return. Any reference sheet or how to write this in the actual string would be greatly appreciated.

Post by manuknecht on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup CODESYS Forge talk (Post)
Hello all I am using an AxisGroup with the Gantry2 Kinematics to move a 2D-Gantry system. When creating the AxisGroup, the SoftMotion_PlanningTask is created automatically with a cycle time of 2 ms in my case. I realized that the maximum cycle time of this task can spike to very high values (up to 60 ms) at lower speeds of the motion, leading to synchronization issues and errors on the axes. The same behaviour - though not as drastic - can be observed with virtual axes too. Is this behaviour intended or to be expected? Can the cycle time or type of the SoftMotion_PlanningTask be changed to prevent these errors? Or is there another fix for this issue? I tried changing the cycle type to Freewheeling, which solved the synchronization issues, but caused an error on the AxisGroup after a while, reading SMC_CP_QUEUE_UNDERRUN. Thanks in advance and best regards Manuel

I am definetly not an expert in this field, but it does seem like you need a propper API key in the URL. Right now you are using the token 'ANWB' in your URL, which the website returns an error, since this is not valid. Somehow you first need a propper API key. I hope that makes sense.

Hello Everyone, When I try to import some POUs that were previously exported from another project as an XML file, I get an error like in attached image and the process does not complete. "There are no objects in the export file..." I am using SP21 Codesys IDE and I do not know which version this XML (*.export) file was previously exported with. Has anyone encountered the same problem? Regards, imdatatas

Post by serwis on Dynamic target position tracking CODESYS Forge talk (Post)
Hello, I am trying to control a servo drive and dynamically set its position. I control the drive via EtherCAT with a cycle time of 500us. I use the MC_MoveAbsolute block for this. The problem is that when using a PID controller, I generate the positions I want the drive to move to on an ongoing basis, and I would like the position to be set immediately. The MC_MoveAbsolute block must receive a rising edge to execute, and I would like the movement to be performed without waiting for this edge. I have created a function that generates a rising edge every 1 ms, but I am unable to change this time to 500 µs because the TON function does not support times shorter than 1 ms. Below is the code to call the rising edge: IF Exe = TRUE THEN delay1(IN:=TRUE, PT:=T#1MS); IF delay1.Q = TRUE THEN Exe := FALSE; delay1(IN:=FALSE); END_IF END_IF IF Exe = FALSE THEN delay(IN:=TRUE, PT:=T#1MS); IF delay.Q = TRUE THEN Exe := TRUE; delay(IN:=FALSE); END_IF END_IF END_IF Here is the code for calling the MC_MoveAbsolute function: MoveDegree( Axis:= Tilt, Execute:= Exe, Position:= position_target - (base_angle_real * feedforward_turn), Velocity:= vel, Acceleration:= acc, Deceleration:= dec, Jerk:= jerk, Direction:= MC_DIRECTION.shortest, BufferMode:= MC_BUFFER_MODE.Aborting, Done=> , Busy=> , Active=> , CommandAborted=> , Error=> , ErrorID=> ); I realize that there are probably better methods for performing this type of task. How can I implement motion with a dynamically changing setpoint? THANKS

is your pointer set to the correct visu client? set a breakpoint in your client iteration and step through the active visu clients like programming system, targetvisu, webvisu,... and check the last usage value of each client

Post by fenicklar on Login problem with FileTransfer on Raspberry Pi 5 CODESYS Forge talk (Post)
Hello everyone, I'm currently trying to set up a FileTransfer function from a Webvisu to my Raspberry Pi 5 on Codesys 3.5 SP 19 Patch 6. I went in the files CODESYSControl.cfg and CODESYSControl_User.cfg and added : [CmpWebServerHandlerV3] AllowFileTransferServices=1 And it seems to be working. However, I cannot access my several Webvisu without putting my login. That's a problem because one of my webvisu is in kiosk mode on the raspberry itself and there is nokeyboard attached, it's just an information screen, but I can't view it. Is there a wey to enable the File Transfer without requiring to login ? Thank you for your time

Post by manuknecht on Detect "Cancel" Press in FileOpenSave Dialog CODESYS Forge talk (Post)
When using the FileOpenSave dialog and using the Visu_FbFileListProvider FB as an In/Output I could not manage to detect the difference of pressing the "Load" button on the dialog vs. pressing the "Cancel" button. In both cases, the selected file is updated if the dialog is closed when checking using the Visu_FbFileListProvider.GetSelectedFileName() command. How can I prevent reading or writing of a file when the "Cancel" button was pressed?

Only idea I have is that new textlists are not loaded with an online change. When you add them, maybe you always have to do a full download first.

In the device selection. Do not filter on Phoenix. Remove this filter and first add an Ethernet Adapter from CODESYS. To this Ethernet adapter add the Profinet Controller. After this you can filter on Phoenix devices in the "add device dialog".
