Post by spiritcore on Server not adding PLC ^{CODESYS Forge talk (Post)}
I added new Gateway and I can see it connected. When I scan the server for PLC, it finds the PLC but when I click the Add To Server button, it shows "PLC was added." in the status. But I can't find the PLC in the list. I tried removing the gateway and re-configure everything again but it didn't solve. Any ideas?

Post by alexgooi on Disable OPC-UA server ^{CODESYS Forge talk (Post)}
Dear Forum, I recently updated to the newest Codesys IDE (3.5 SP19 patch 5) The program wouldn't download cause of the amount of OPC-UA server tags (see picture) I'm not planning on using the OPC-UA server and therefore I unchecked the "Support OPC-UA features" checkbox in the symbol configuration. But this didn’t solve the issue of the OPC-UA server exceeding its license. How can I disable the OPC-UA server while still maintaining the symbol configuration. Thank you in advance Alex

Post by kislov on Change modbus server parameters from program ^{CODESYS Forge talk (Post)}
Use in IEC-code: Modbus_Serial_Device.UpdateComPortSettings(...) https://content.helpme-codesys.com/en/libs/IoDrvModbusSerialSlave/Current/pou-ModbusSerialDeviceDiag/UpdateComPortSettings.html Take note: "Only possible if server is disabled (see xEnable Input)" So: Modbus_Serial_Device.xEnable := FALSE; Modbus_Serial_Device.UpdateComPortSettings(...) Modbus_Serial_Device.xEnable := TRUE; Please note that after PLC reboot the values from the GUI (from your screenshot) will be applied again. So you need to save values from HMI in RETAIN and restore them after start of application.

Post by garrian on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
Thanks for your reply. I belive it is contiguous, I'm writing to adress 0 to 4. Or, do you mean something else? Well, something is happening. If I on the client set adress 1,2,3 to true, only 1 is set to true on the server side. On the client side, the data is array of word. But on the server side, the coils are array of bool. Holding register is array of word on server side. Can this be a problem? Attached screenshot of how it looks at the server side.

Post by snhatton on Alarm Management - latched variable represented as Text list ^{CODESYS Forge talk (Post)}
Hi There, For my understanding: are you trying to display the contents of a text list in an alarm message based on the id? For example, you could maintain a text list of common alarm messages, and then display based on which message is true?
