Error
Code Error Contents and Cause
(SD0)
• The number of actually mounted
modules is different from the number
of modules set in the network
parameter of the MELSECNET/G.
• The head I/O number of the actually
mounted module is different from the
one set in the network parameter of
the MELSECNET/G.
• Data cannot be handled in the
parameter exists.
• The network type of MELSECNET/G
is overwritten during power-on.
(When changing the network type,
switch RESET to RUN.)
• The MELSECNET/G module is
3100
specified for the head I/O number of
network parameter in the
MELSECNET/H.
• The MELSECNET/H module is
specified for the head I/O number of
network parameter in the
MELSECNET/G.
• Although the MELSECNET/G module
is mounted, network parameter for
the MELSECNET/G module is not
set.
• Although the MELSECNET/G and
MELSECNET/H modules are
mounted, network parameter for the
MELSECNET/H module is not set.
*3 The module whose first 5 digits of serial No. is 04012 or later.
*4 The module whose first 5 digits of serial No. is 07032 or later.
*5 The MELSECNET/H module whose first 5 digits of serial No. is 08102 or later.
*6 The module whose first 5 digits of serial No. is 09012 or later.
*7 The Universal model QCPU except the Q02UCPU.
Corrective Action
• Check the network parameter and
actual mounting status, and if they
differ, make them matched. When
network parameters are modified,
write them to the CPU module.
• Check the setting of extension base
unit stage number.
• Check the connection status of
extension base unit and extension
cable. When the GOT is bus-
connected to the main base unit or
extension base unit, also check its
connection status.
If an error occurs even after
performing the above checks, the
hardware may be faulty.
(Contact your local Mitsubishi
representative, explaining a detailed
description of the problem.)
