The command
requires a response,
but the command
after conversion does
not require a
response (e.g.,
broadcasting)
Check the specifications of
the command to be con-
verted.
A response
was received
from the
remote device
after a
response time-
out error was
received for a
converted
command that
was sent to the
remote device.
0205 hex
(response
timeout), etc.
*_P1(orP2)_T
imeoutErr
(Timeout
Error) is set
to TRUE.
A Serial Gateway
response timeout
occurred, but the
response data was
received normally
after the timeout.
This occured because
the
*_P1(orP2)_PmrSgw
RespTimeoutCfg
(Serial Gateway
Response Timeout
Monitoring Time) set-
ting is too short.
Set a longer time for
*_P1(orP2)_PmrSgwRespTi
meoutCfg (Serial Gateway
Response Timeout Monitor-
ing Time).
An error end
code was
returned to the
transmission
source.
0206 hex
(transmis-
sion line
error)
*_P1(orP2)_F
CSErr (FCS
Check Error)
or
*_P1(orP2)_
ParityErr
(Parity Error)
is TRUE.
Either of the following
errors occurred in the
protocol after conver-
sion.
Conversion to Com-
poWay/F command:
BCC error or parity
error
Conversion to Mod-
bus-RTU command:
CRC error or parity
error
Conversion to Mod-
bus-ASCII command:
CRC error or check-
sum error
Conversion to Host
Link command: FCS
error or parity error
Use shielded twisted-pair
cables.
Lay power lines separately by
using ducts.
Increase the number of
resends at the command
source.
Perform communications
retry as required.
Other error
end code

The Serial Gateway
was executed, but the
error completion
occurred.
Perform error processing
based on the following table
of Cause and Countermea-
sure by Command End Code.
