This section provides troubleshooting information for your Modular PLCs
XControl: XC-104-…, XC-204-…, XC-303-… in case it does not behave as
expected.
Fault Cause Remedy
XControl will not boot
up
There is no 24 VDC supply voltage Check the input wiring.
Switch on XControl.
PLC LED = red; solid Indicates a runtime system error.
Device hangs on startup;
the runtime system does not start, a connec-
tion cannot be established through XSOFT
CODESYS;
LED PRG = OFF,
Cause 1: Invalid OS version loaded; the OS
version on the device is too new/old to support
the respective PLC runtime system.
Cause 2: The device's last restart was trig-
gered by a hardware watchdog timeout.
In both cases, a LOG file will be written to
/var/log/codesyscontrol.log
Cause 1: Install the appropriate oper-
ating system for the runtime system.
Cause 2: Start the device manually; if the
fault occurs again, check the application
for errors that trigger the watchdog.
If necessary, check whether the boot
application version matches the runtime
system version.
The runtime system starts,
PRG LED = ON or OFF,
Cause: Retentive data could not be loaded.
Additional information can be found in the LOG
file, which can be read with XSOFT CODESYS.
Log in to the device through XSOFT
CODESYS and read the log file
LED PRG = ROT Indicates an application error.
• The attempt to load the boot project failed.
• An exception occurred in the application.
Additional information can be found in the LOG
file, which can be read with XSOFT CODESYS.
