6.1.5 Parameter Details for MSG-SND Function
This section describes the parameter list in detail for MSG-SND function.
( 1 ) PARAM00: Processing Result
The processing result is output to the upper-place byte of PARAM00. The lower-place byte is for system analysis.
If an error occurs, troubleshoot the problem according to the value of the processing result as listed below.
„
Datails of Remote Node Error
The following shows the contents of the message function PARAM00 (processing results) at error response reception
from a remote node.
Processing result (PARAM00): ††72H (†† indicates the error code.)
ΠWhile the FA link specification states that an error code is one byte (eight bits), the MP specification states the high-
est bit of a processing result is fixed to “1”, so the parameters that can be identified error codes are the remaining
seven bits.
(“1 * * * * * * ”... * indicates a bit available as an error code.)
Accordingly, 00H to 7FH for seven bits can be represented as error codes.
Value of Processing Result Meaning
00††H Processing in progress (busy)
10††H Processing completed (Complete)
8y††H Error occurred (Error)
Error Error Contents Description
80††H – Reserved by the system.
81††H Function code error
An undefined function code was sent or received.
Check PARAM04 (function code).
82††H Address setting error
One of the following settings in not within the valid range. Check the settings.
PARAM05 (data address)
PARAM11 (holding register offset)
83††H Data size error
The size of the sent or received data is not within the allowable range.
Check PARAM06 (data size).
84††H Circuit number setting error
The circuit number is not within the allowable range.
Check the circuit number in the MSG-SND function.
85††H Channel number setting error
The transmission buffer channel number is not within the allowable range.
Check the transmission buffer channel number in the MSG-SND function.
86††H Remote node number error
The remote node number is not within the allowable range.
Check PARAM02 (remote node number).
87††H – –
88††H Transmission device error
An error response was returned from the transmission device.
Check the connection to the equipment. Also, be sure that the remote device
can communicate.
89††H Device selection error
An unavailable device was set. Check the transmission device type in the
MSG-SND function.
8072H to
FF72H
Remote node error
An error response was returned from the remote node. Refer to error code and
remove the cause.
