Code States

0 Continue [When using MELSECNET/(II)]
(1) When the link range at a data link
CPU which is also a master station
(station number = 00) is set by
parameter setting at a peripheral
device, for some reason the data
written to the link parameter area
differs from the link parameter data
read by the CPU. Alternatively, no
link parameters have been written.
(2) The total number of slave stations is
set at 0.
(3) The head I/O number of the network
parameters is incorrect.
470 [When using MELSECNET/10]
(1) The contents of the network refresh
parameters written from a
peripheral device differ from the
actual system at the base unit.
(2) The network refresh parameters
have not been written.
(3) The head I/O number of the network
parameters is incorrect.
471 [When using MELSECNET/10]
(1) The transfer source device range
and transfer destination device
range specified for the inter-network
transfer parameters are in the same
network.
(2) The specified range of transfer
source devices or transfer
destination devices for the inter-
network transfer parameters spans
two or more networks.
(3) The specified range of transfer
source devices or transfer
destination devices for the inter-
network transfer parameters is not
used by the network.
472 [When using MELSECNET/10]
The contents of the routing parameters
written from a peripheral device differ
from the actual network system.
473 [When using MELSECNET/10]
(1) The contents of the network
parameters for the first link unit,
written from a peripheral device,
differ from the actual network
system.
(2) The link parameters for the first link
unit have not been written.
(3) The setting for the total number of
stations is 0.
Error and Cause
9 - 37
Corrective Action
(1) Write the parameters again and
check.
(2) Check the station number settings.
(3) Check the head I/O number of the
network parameters.
(4) Persistent error occurrence may
indicate a hardware fault. Consult
your nearest Mitsubishi
representative, explaining the nature
of the problem.
Write the network refresh parameters
again and check.
