Post by phuvutran on CODESYS Date/Time Picker in Dialog does not update value on close (focus issue) – any workaround?
CODESYS Forge
talk
(Post)
Hi everyone, I am working with CODESYS 3.5.21 and using the Date/Time Picker inside a dialog (popup visualization). I noticed a behavior that seems problematic: The Date/Time Picker does NOT update the bound variable immediately. It only updates when the control loses focus/select. This causes an issue in my dialog: User selects a new date/time Immediately presses OK (which closes the dialog) The new value is NOT saved The variable still contains the old value So it seems the Date/Time Picker still holds the value internally and does not commit it before the dialog is closed.

I have seen similar behavior with some visualization controls in CODESYS. It seems the Date/Time Picker only commits the value after losing focus, so closing the popup immediately with the OK button can skip the update. One possible workaround is forcing focus to another control before closing the dialog or adding a short delay before executing the close action. Geometry Dash Lite

Hello Hannibal, I am using real vars and it works, however, if I update those vars in real time it doesnt quite change it on y axis, do you think it is because it is not an integer?

Post by jroddball79 on PM556-TP-ETH — How to change IP address without overwriting the PLC program?
CODESYS Forge
talk
(Post)
Still looking for a solution. I have gathered more information that might help: Device: ABB AC500 PM556-TP-ETH Firmware version: 2.4.2.14993 (dated 2014) Open ports confirmed: 502 (Modbus TCP), 1200 and 1201 (CODESYS runtime). SSH (22) and HTTP (80) are not reachable. No SD card in the PLC. I can connect via Automation Builder using the current IP and Online Login works, but I have no original source project available. Automation Builder requires a full PLC download to apply IP changes, which we want to avoid as it would overwrite the running program. Any guidance on how to change the IP without a full download would be greatly appreciated. I am also open to solutions using third party tools, DCP protocol, or scripts. Thank you

Post by josepmariarams on Limit Axis CNC Jerk using SMC_Polynomial_AbsMaxLocs
CODESYS Forge
talk
(Post)
Dears. Until now, I have been using CNC libraries with Codesys 3.5SP11. I was using SMC_Polynomial_AbsMaxLocs function, from CNC library, to calculate the axis jerks, interpolating splines, to limit it. Now I have passed to SP20, and the functions which calculates the zeros and the maximum-minimum and zeros of polynomials has been disapeared. Questions: -Exist any FB wich can limit the jerk of individual axis in CNC? -Exist any other functions which can calculate max-min and zeros of polynomials? Thanks
