Subject to change without notice
Modbus/TCP Ethernet Gateway
The only exception is the UE410-EN IP address, which is not reset to factory settings
with this action.
After resetting to factory settings, the UE410-EN does not identify the connected Flexi
Classic module again, but displays all modules as “Unknown Modules”. In addition the
UE410-EN loses the system information MOD-ID, CRC1, CRC2, SWVERSION_H, SW-
VERSION_L, FUNCTION, KONF, CRC_H CODE and CRC_L CODE and transfers zeros into
the corresponding data sets. Restarting the Flexi Classic system remedies this problem.
Interrupt the power supply of the Flexi Classic system and switch on again.

Troubleshooting
Error
Cause
Remedy
The browser does not find
the UE410-EN homepage
during configuration.
UE410-EN has no power
supply.
UE410-EN is not in the same
physical network as the PC.
The PC is configured to another
subnet mask in the TCP/IP
settings.
UE410-EN has already been
configured once and has a
fixed set IP address or an IP
address assigned by a DHCP
server that is not recognised.
Establish the power supply.
Check the Ethernet wiring and
network settings on the PC and
correct if necessary.
Set the subnet mask on the PC to
255.255.0.0 (factory setting of the
UE410
F
EN).
The software tool Flexi Classic
IP
F
Link can be used to scan the
network for connected Flexi Classic
modules and to determine the
network address.
UE410-EN does not supply
any data.

UE410-EN is operated in slave
mode, the IP address is as-
signed from a DHCP server.
After the UE410-EN or the
DHCP server has been restar-
ted, a different IP address that
is unknown to the PLC has
been assigned to the
UE410
F
EN.
Either assign a fixed IP address to
the UE410
F
EN, or reserve a fixed IP
address for the UE410
F
EN in the
DHCP server (manual assignment
by means of the MAC address of
the UE410-EN).
