3.3 Message Communication Error
3.3.3 Checking the Message Function
3-14
[ a ] Checking the process result (PARAM00) when using the message transmission function (MSG-
SND)
• When the process result is other than the communication section error (88xxH)
• When the process result is the communication section error (88xxH)
For the details on the communication section error (88xxH), refer to [ c ] Checking the status (PARAM01) of

81xxH
Function code error
Unused function code was transmitted from the
local station.
Check PARAM04 (function code).
Unused function code was received from the
remote station.
Check whether the remote station is transmit-
ting valid data.
82xxH
Error in setting address
One of the following settings is out of the set-
ting range.
PARAM05 (data address)
PARAM08 (coil offset)
PARAM09 (input relay offset)
PARAM10 (input register offset)
PARAM11 (holding register offset)
Check the settings to the left.
83xxH
Data size error
The transmit data size of the local station is out
of the setting range.
Check PARAM06 (data size).
The receive data size from the remote station is
out of the setting range.
Check whether the remote station is transmit-
ting data of a valid size.
84xxH
Error in setting circuit
number
The circuit number is out of the setting range.
Check Cir-No (circuit number) of the message
function.
(Refer to [ c ] Cir-No (Circuit number) of 3.3.3
( 2 ) Checking the Entries to the Message
Function.)
85xxH
Error in setting channel
number
The communication buffer channel number is
out of the setting range.
Check Ch-No (communication buffer channel
number) of the message function.
(Refer to [ d ] Ch-No (Communication Buffer
Channel) of 3.3.3 ( 2 ) Checking the Entries to
the Message Function.)
86xxH
Connection number
error
The connection number is out of the setting
range.
Check PARAM02 (connection number).
89xxH
Device select error Unavailable device is set.
Check Dev-Typ (transmission device type) of
the message function and select the appropriate
device type.
(Refer to [ a ] Dev-Typ (Transmission device
type) of 3.3.3 ( 2 ) Checking the Entries to the
Message Function.)

Communication sec-
tion error
An error response was
returned from the com-
munication section
(transmission device).
The remote station is not in the communication
enabled status.
Check the communication settings of the
remote station.
More than one message function has been exe-
cuted simultaneously for the same Cir-No (cir-
cuit number) and Ch-No (communication
buffer channel number).
Review the ladder program so that more than
one message function will not be executed
simultaneously.
(Refer to [ c ] Cir-No (Circuit number) and [ d
] Ch-No (Communication Buffer Channel) of
3.3.3 ( 2 ) Checking the Entries to the Message
Function.)
More than one message function has been exe-
cuted simultaneously for the same Cir-No (cir-
cuit number) and PARAM02 (connection
number).
Review the ladder program so that more than
one message function will not be executed
simultaneously.
The message function was executed while the
Ethernet Module was not ready to receive mes-
sage transmission or receive requests (in a sta-
tus other than the RUN status).
Adjust the timing for executing the message
function for the first time in the ladder pro-
gram, for example by using a timer command.
