..strange just switching of this device without graceful Linux OS shutdown? Reset orgin on the device tree and a new download of the application will bring it up and running again but sure then the persistent data are for sure lost.

When you use a string value 0 will be the end terminator. Everything after this will not be in the string. I guess byte 2394 has a value 0.

I have a snippet of code that I was given as a reference in ST. ** ModbusMasterRTU( xConnect:= TRUE, IPort:= IoConfigGlobals.COM1, // IoConfigGlobals.RS232485Interface, // COM1=Front Port / Serial module = Name of module in Devices structure I/O list udiBaudrate:= 19200, usiDataBits:= 8 , eParity:= WagoTypesCom.eTTYParity.None , eStopBits:= WagoTypesCom.eTTYStopBits.One , eHandshake:= WagoTypesCom.eTTYHandshake.None , ePhysical:= WagoTypesCom.eTTYPhysicalLayer.RS485HalfDuplex, xIsConnected=> xIsConnected , xError=> , oStatus=> , eFrameType:= WagoAppPlcModbus.eMbFrameType.RTU , tTimeOut:= T#1S, utQuery:= utQuery , xTrigger:= SEND, utResponse:= utResponse)** What is the meaning of => in this context?

Thats what I did. The files existed originally, but when I had problems logging in as described I deleted those files (if they in some way had been corrupted causing my problems to login?). After that I have not managed to get the system to re-created these def-files. I manually created the folder structure (from CODESYS file browser) but this has not helped.

Post by wedahitha on Could not open library 'SysSocket23, ^{CODESYS Forge talk (Post)}
Hi there, I am trying to open a codesys project done by someone else and Once I install all the libraries I get this error [ERROR] : Library Manager [PROJECT 01: PLC Logic: Application]: Could not open library 'SysSocket23, * (System)'. (Reason: The library 'SysSocket23, * (System)' has not been installed to the system.) SysSocket23 is a standard library and I also tried using the same OSCAT library which was from the original computer that made this code. Using CODESYS V3.5 SP18 Patch 2 Please help me how to solve this problem.

Post by davidbo on How to stop dhcpcd and use SysSockSetIpAddressAndNetMask to set address? ^{CODESYS Forge talk (Post)}
It is stated: "Dynamic ip address, provided by DHCP, BOOTP, etc. Cannot be changed by SysSockSetIpAddressAndNetMask()" Therefore I try to stop dhcpcd and flush the eth0 like this VAR CONSTANT flushIP:STRING:='sudo ip addr flush dev eth0'; stopDHCP:STRING:='sudo systemctl stop dhcpcd'; END_VAR SysProcessExecuteCommand2(pszCommand:=stopDHCP, pszStdOut:=stdout,udiStdOutLen:= SIZEOF(stdout),pResult := ADR(Result)); SysProcessExecuteCommand2(pszCommand:=flushIP, pszStdOut:=stdout,udiStdOutLen:= SIZEOF(stdout),pResult := ADR(Result)); Besides losing the connection when flush occurs the CODESYS halts, seen on the display and I cannot see why, because I have lost the connection from my IDE. Why does the flush command halt the execution of the application?

Ok, think I understand. The reason for the error is I try to include complex variables (FB) in the persistenced data. I will try to use {attribute 'ac_persist_exclude'} to exclude those elements.

Not sure, but maybe it related to the style. Go to the Visualization Manager in your project and see if a style is selected, or choose another style to see if this helps.

Lt. Release notes ("J1939: ChangeAddress method does not work properly.") wurde hier verbessert. Leider habe ich keine Beschbreibung dazu gefunden. Wie muss der Aufruf angepasst werden?

Post by ph0010421 on Task time too fast? ^{CODESYS Forge talk (Post)}
Hello I've made an FB which is a TCP server. It uses the excellent CAA NetServices library. If I have the FB in a task <4ms, then the RT crashes immediately at boot up. If the task >=4ms, it starts and runs perfectly. This is even if the block is not doing anything; just instantiated. Am I missing something silly? Why would a low task time cause this? 4ms is perfectly adequate, but I'm just interested why... thanks PH

Hi, jain. wir haben mit IFM gesprochen. Sie sagen es liegt an Codesys selbst. Die Daten seien anscheinend nicht konsistent wenn das Projekt zu und erneut geöffnet wird, sei ein probkem von SP11. IFM wird im Sommer ein neues Package rausgeben wo sie auf eine neue CS Version wechseln, dort soll das Problem dann behoben sein. Wir haben zwar einen Workaround rausgefunden aber jenachdem was du in der Safety treibst geht dieser dann nicht mehr. schreib mir zur not eine PN wenn du mehr wissen willst.

Post by kut69 on Retain / Persistent Variables in Codesys for Raspberry Pi ^{CODESYS Forge talk (Post)}
Hi, I am interested in details about the .ret file in the filesystem. I have already a project where the file is used (write on demand, read by start) and I want to share it as 'default input' for test devices using the identical application. Opening the .ret file content in a hex editor (I only use a single string retain var) I asked myself what the meaning of the first 24 bytes is. It neither contains a handle to the application nor a reference to the variable. Is this maybe a timestamp? Or a CRC/checksum? Regards, Thomas
