There still is no solution to this. I am running Modbus version 4.4.0.0 and it still wont let me add more than 10 channels. Does anyone have a solution for this?

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

81.920.000 counts per rotation?!? maybe 8.192.000 counts per rotation would work?

I initially created a SoftMotion axis for my EtherCAT CoE drive. I wanted to change it to use SoftMotionLight so I deleted the SM node, which left an <empty> node. I created the SML device, but the <empty> node remains. How can I remove that from the tree? </empty></empty>

Post by beavel on Customizing FileOpenSave Dialog and Keypad Integration in Visualization
CODESYS Forge

(Post)
Hi all, I'm looking to adjust the visualization of the FileOpenSave dialog. Is there a library or visualization file associated with this dialog that can be extracted, customized, and re-imported into the project — similar to how the user management dialogs can be handled? Alternatively, is there a supported way to replace or override the default dialog with a custom one? Also, is it possible to configure the FileOpenSave dialog to use a custom keypad for text input? The rest of the project uses a custom keypad due to readability concerns (the default one is too small), and this inconsistency is now quite noticeable. Any guidance or workarounds would be greatly appreciated. Thanks in advance! @thk @eschwellinger @sheberle

1 + Replying in hopes of getting an answer here. I would also like to modify the look of the FileOpenSave Dialog. I have successfully adjusted the looks of the User management Dialogs but can not find a library file to adjust this particular one. Any help would be helpful. @thk @eschwellinger @sheberle .

For reference, it was just me being unfamiliar with EtherCAT in CoDeSys. Anyone with knowledge who would have opened the ScanResult screenshot would have identified that the preceding EK1100 was the device missing in the library. Bottom line - Do something else for a while and then get back at it with fresh eyes!

Hi imdatatas, thanks for your feedback. This change was intentional, as the quadratic ramp type has many advantages over the trapez ramptype. Sorry to hear it causes problems in your situation. Can you please shortly explain the nature of the problems? Best regards, Georg

Hi kporter, a more direct way would be to use SMC_FollowPosition to write the set positions directly to the servo drive. This FB has reacts on changes of the fSetPosition on each call, without a need for a rising edge on Execute. See https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html. Best regards, Georg

I have a problem which I have identified with a device-update from 4.14.0.0 to (4.15.0.0-4.17.0.0) where the newer versions will stop any local access to the internal web page with the browser responding "The requested URL requires authentication". Setting the device back to 4.14.0.0. the web page will respond. Access to web page through Automation server is possible also for the newer version, but not "local" access. Runtime (Codesys control for linux SL) is on 4.17.0.0. I have tried to manipulate settings for 'Access-Control-Allow-Origin' '*' always; through nginx (normally a proxy_pass to localhost:8080). Also tested bypassing nginx by accessing 8080 directly with the same result.
