After loading, it seems to be quite responsive. It's just the initial loading that is taking a long time.

For anyone reading this after the fact, it seems my issue was Alarm Task Manager. Deleting it from my program fixed the issue.

no need to activate application composer. It is part of the licensefree part.

CODESYS Forge

(Post)
Hi, I'm struggling with updating my xc303 to firmware 3.5.17. It is possible only via USB port. I've installed proper update files on the USB then plug it into the PLC's USB port and restarted the device. Shortly after LED's on the PLC started to blink, so updating process has started. But after 10 minutes the PLC LED turned off and after all I could't serach for this PLC in Codesys, but could ping it. Could someone eplain to me proper procedure of updating the fimrware in XC303 via USB? Is it neccesary to STOP the PLC switch after pluging the USB?

After many tests i see that problem comes when serial communication established for modbus rtu. If the slave device not connected we don't see the exception. If the slave device connected at serial port then we have exception about 1 hour after startup and every 10 or 15 minutes. Any suggestion?

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
