Hey Guys, I am trying to create a ModbusTCP_FunctionCode06 which i will use as a single write register for programming a test code for Power Meter(PQM_1000) I have tried to reserach how to add it it from the libraray manager and have largely been unsuccessful. Does anyone know where I should Look? And by the way, I am i wam using Codesys V3.5 Vs 21 Patch 4 I look forward to something positive. Best, Kmax365.

Hi You can add a channel to the standard Modbus TCP library with FC06. From the device tree, add Ethernet device, ModbusTCP master then finally a ModbusTCP slave (your power meter). You can add read/write channels (for any FC) in here. As you add these devices, the necessary libraries will be inserted for you. Alternatively, I have a ModbusTCP client/server library if your RT doesn't have Modbus (I think they all do these days?)

Post by jroddball79 on PM556-TP-ETH — How to change IP address without overwriting the PLC program?
CODESYS Forge
talk
(Post)
Hi, I need to change the IP address of an ABB PM556-TP-ETH using ABB Automation Builder. The situation is: I have connectivity to the PLC using the current IP (configured in Communication Settings) Online Login works fine The Network Scan does not detect the PLC IP-Configuration tool shows all fields disabled I don't have the original project source, only an empty project The PLC has no SD card inserted The Online menu does not show an Upload option When I modify the IP in the project and connect, Automation Builder shows: "The PLC configuration needs to be updated. A full PLC download is required" I'm afraid a full download will overwrite the running program. Is there any way to change only the IP address without overwriting the application? I'm also open to solutions using third-party tools, Python scripts, or any other method (DCP protocol, direct TCP communication, etc.) as long as it doesn't overwrite the running application. Thank you

Post by phuvutran on CODESYS Date/Time Picker in Dialog does not update value on close (focus issue) – any workaround?
CODESYS Forge

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.
