Appendices
( 9 ) Remote CPU Number (PARAM07)
Set a remote CPU number.
When the remote device is MP2000 series, specify “1”.
When the remote device is a controller manufactured by YASKAWA Electric Corporation, but other than the MP2000
series, and comprises multiple CPU modules, specify the destination CPU number.
Otherwise, specify “0”.
( 10 ) Offset (PARAM08 to PARAM11)
Specify the offset addresses of read data storage areas and write data source of the transmission side.
The address for the transmission side will be displaced by the number of words designated by the offset.
Note: 1. For more information, refer to G.1.8 Relationship between Data Address, Data Size, and Offset for
MSG-SND Function.
2. The offset cannot be a negative value.
The offset parameter is prepared for each target data type.
The following table lists the offset parameters.
The valid offset parameter may differ, depending on the function code.
The following table provides the valid parameters for each function code.
Note: √: Available, –: Not available
Table G.4 Offset Parameter List
Parameter Content Description
PARAM08 Coil offset Sets the coil's offset word address.
PARAM09 Input relay offset Sets the offset word address of an input relay.
PARAM10 Input register offset Sets the offset word address of an input register.
PARAM11 Holding register offset Sets the offset word address of a holding register.
