Error messages
The JUMO variTRON 500 does not generate any JUMO-specific error messages relating to PROFINET.
However, it does support the error messages in CODESYS®.

6.2
Error message in the setup program
If the JUMO IO device (e.g. JUMO variTRON 500) is configured using the LAN1 interface (which is also
used for PROFINET), the following error message may appear in the setup program.
When the configuration is transferred, the Ethernet connection is interrupted because the LAN1 IP pa-
rameters are reset. This is required to ensure that an IO controller can assign the IO device a device
name and IP address. However, the configuration is still transferred correctly. Normally the application
will start and switch to the status RUN. The IO device can then be found and configured by an IO con-
troller.
This error message only occurs when starting up the system for the first time. If the IO device has already
been assigned a device name and IP address by an IO controller, the data will be transferred without
errors.
NOTE!
To configure the JUMO IO device, use a free LAN interface (LAN2 or LAN3, if available) or a USB Ether-
net adapter.
As can be seen below, the configuration was successfully transferred to the device because the appli-
cation has the status RUN and is ready for use. The JUMO IO device can now be found by an IO con-
troller so that it can be assigned a device name and IP address. This is shown using the PRONETA tool
from Siemens by way of example. As can be seen, the IP parameters were reset when the configuration
was applied, causing the connection to be interrupted in the setup program.
