The con-
verted
command
could be
sent to the
remote
device but
a normal
response is
not
received
from the
remote
device.
The serial
communica-
tions mode is
set to Serial
Gateway or
protocol
macro mode.
The SD
@
and COM
@
indicators
are flashing
but the RD
@
does not
flash.
0205 hex
(response
timeout), etc.
Bit 05 of CIO
word n+8/
n+18 (Serial
Gateway Send
Start Time-
out/ Response
Timeout) is
ON.
A Serial Gateway
response timeout
has occurred and
the response data
cannot be
received after the
timeout. Either of
the following
causes is possible.
Perform one of the fol-
lowing:
A remote device
that can receive
the command after
conversion does
not exist at the
specified FINS
destination
address.
Check the device at the
specified FINS destina-
tion address.
The sent com-
mand frame is ille-
gal.
Revise the command
frame to be converted.
The communica-
tions conditions
and baud rate set-
tings for the serial
communications
path do not match
the settings at the
remote device.
Revise the settings in
the Setup Area and at
the remote device.
Cable connec-
tions are incorrect
or faulty.
The RS-422A/485
port setting (2-wire
or 4-wire) is incor-
rect.
Adapters such as
the NT-AL001-E
are incorrectly
wired or terminat-
ing resistance is
not set correctly.
Review the wiring or
switch settings.
Turn ON the terminating
resistance switch at two
locations (remote device
or board) and turn OFF
the terminating resis-
tance switch at all other
nodes.
A command was
sent in a protocol
not understood by
the remote device.
Check the command
specifications of the
remote device and the
source of command con-
version.
A hardware error
has occurred in
the remote device.
Replace the remote
device.
