That is an output of the Function Block ModbusMasterRTU example: xIsConnected=> xIsConnected In this line the VAR ModbusMasterRTU.xIsConnected is written to VAR xIsConnected xError=> is writing to nothing here.

in your project, to access /var/opt/codesys/PlcLogic/my.file, use the string 'my.file' or '$$PlcLogic$$/my.file'

permissions, since a security related change it is not allowed to save files outside of the Plclogic directory. Use /var/opt/codesys/Plclogic/

use the PLClogic directory to read / write files. /var/opt/codesys/PlcLogic this is due security reasons forced to use.

I have code written since version 3.5.16 to access the USB drive, how can I do that now the file access has been taken away? I have tried adding a sybolic link to the usb drive in the following directories: /var/opt/codesys/PlcLogic/ /var/opt/CODESYS/PlcLogic/ /opt/CODESYS/PlcLogic/ I still recieve a "FILE_OPERATION_DENIED" response when accessing the USB drive.

Post by janber0206 on Adding PLC to the List view resolves in Unknown Error ^{CODESYS Forge talk (Post)}
Problem Solved The Problem was within the Usermanagment. There should be 6 files for the Usermanagment in /var/opt/codesys/ .UserMgmtDB.csv .UserMgmRightstDB.csv .GroupDatabase.csv .UserDatabase.csv_ .GroupDatabase.csv_ .UserDatabase.csv The file .UserMgmtDB.csv was missing. I moved the other files in a savefolder. Full Step by step instructions stop the runtime with sudo /etc/init.d/codesyscontrol stop rename the following files on the PI: (or save them and then delete them) in this directory: /var/opt/codesys/ .UserMgmtDB.csv .UserMgmRightstDB.csv .GroupDatabase.csv .UserDatabase.csv_ .GroupDatabase.csv_ .UserDatabase.csv then restart the Runtime: sudo /etc/init.d/codesyscontrol start now reconnect the PLC via the Automation Server - here you will be asked to create a new CODESYS user password, The user management files deleted above are then created again (in /var/opt/codesys/ on the PI).

Post by wiresplus on Cannot get INT_TO_TIME working ^{CODESYS Forge talk (Post)}
Hello, I have a simple TON timer. It is watching prime loss for a pump. The operator can set the delay via the HMI, it is an integer (seconds) As the TON uses milliseconds, we then multiply the entry by 1000 to get seconds. Seems simple, but... VAR PrimeTimer : TON; primetime : INT; END_VAR PrimeTimer(in:=State>0 AND FlowRate<MinimumFlow,pt:=INT_TO_TIME(primetime *1000)); For an entered 15 seconds (VAR primetime:=15;) the timer reads 49d17h2m26s760ms !!!! What am I doing wrong?

Post by wollvieh on License Activation Problems ^{CODESYS Forge talk (Post)}
on a raspberry pi delete the folder and its content before licensing. /var/opt/codesys/cmactlicense If you plug this SD card in another raspi ( which has another hw-serial number) you'll get a second empty softcontainer. This could lead to an unlicensed PFC (it could only handle one container) The solution is: To delete the /var/opt/codesys/cmactlicense directory and content of it and then aktivate the lizenz via WibuCmRau file and Lizenzmanager.
