 Offsets (PARAM20 to PARAM27)
These parameters set the offset for the data address in the MP3000.
The MP3000 will offset the address by the number of words specified by the offset.
Note: An offset cannot be a negative value.
Offset parameters are provided for each of the target register types.
The following table lists the offset parameters.
The offset parameters that can be used depend on the function code.
The following table lists the valid parameters for each function code.
 Data Relay Offset (PARAM28 and PARAM29)
These parameters are not used for the FINS protocol.
 Data Register Offset (PARAM30 and PARAM31)
These parameters are not used for the FINS protocol.
 Output Coil Offset (PARAM32 and PARAM33)
These parameters are not used for the FINS protocol.
 Output Register Offset (PARAM34 and PARAM35)
These parameters are not used for the FINS protocol.
