[ a ] Parameter Details
This section describes the parameters in detail. The parameter number corresponds to the word offset from the first
address of the parameter list.
For example, if the first address of the parameter list is MA00100, set the value in MW00110 to set PARAM10.
„ Processing Result (PARAM00)
This parameter outputs the result of processing to the upper byte. The lower byte is used for system analysis.
• 00†† hex: Processing (Busy)
• 10†† hex: Processing completed (Complete)
• 8††† hex: Error
The following errors can occur.
• 81†† hex: Function code error
An unused function code was received.
• 82†† hex: Address setting error
The data address, coil offset, input relay offset, input register offset, or hold register offset is set
outside of the valid range.
• 83†† hex: Data size error
The size of the send or receive data was outside of the valid range.
• 84†† hex: Circuit number setting error
The set circuit number is outside of the valid range.
• 85†† hex: Channel number setting error
The set channel number is outside of the valid range.
• 86†† hex: Station address error
The set station number is outside of the valid range.
• 88†† hex: Communications section error
The communications section returned an error response.
• 89†† hex: Device selection error
A device that cannot be used was selected.
