The SP-COP2-ENI module
does not provide any data.
• The SP-COP2-ENI has been
configured for data trans-
mission to the PLC, but no
Ethernet communication
has been established or the
communication is faulty.
• Duplicate IP address detec-
ted. Another network de-
vice has the same IP
address.
• Incorrectly formatted PRO-
FINET device name
• PROFINET IO must be activated
in the project file. At least one
Ethernet link must be establis-
hed. Check the Ethernet wiring,
check the Ethernet settings in
the PLC and in samosPLAN
6.
• Correct the IP address and
switch the system off and on
again.
• Compare the device name
between the PROFINET master
and the SP-COP2-ENI module.

• Configure the SP-COP2-ENI
module with a project file in
which PROFINET IO is activated
and transfer the configuration

COP2-ENI module is assig-
ned by a DHCP server.
Following a restart of the
SP-COP2-ENI module or the
DHCP server, another
address was allocated to
the SP-COP2-ENI module,
which is unknown to the
PLC.
• Either assign the SP-COP2-ENI
module a permanent IP
address or reserve a perma-
nent IP address for the SP-
COP2-ENI module in the DHCP
server (manual assignment u-
sing the MAC address of the SP-
COP2-ENI module).
