Cause and
correction
Assumed cause Correction Prevention
There is no mounted NX Unit with the
serial number that you set in the Unit
configuration information registered in
the CPU Unit.
To match the actual configuration with
the Unit configuration information,
match the serial number of the rele-
vant NX Unit . To match the Unit con-
figuration information with the actual
configuration, download the Unit con-
figuration information with the serial
number of the relevant NX Unit to the
CPU Unit.
Read the serial numbers of the actu-
ally mounted Units into a project in
the Sysmac Studio before you set the
Serial Number Verification setting to
verify the serial numbers.
