Appendices
( 9 ) Remote CPU Number (PARAM07)
Refer to
G.1.4 ( 9 ) Remote CPU Number (PARAM07)
on page A-49.
( 10 ) Offset (PARAM08, PARAM09, PARAM10, PARAM11)
Specify the offset addresses of the read data storage area and the 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
on page A-66.
2. The offset cannot be a negative value.
The offset parameter is prepared for each target data type.
The following table provides the offset parameters.
The valid offset parameter may differ according to function code.
The following table provides the valid parameters for each function code.
( 11 ) Reserved by System 1 (PARAM12)
Used by system (the channel number of the communication buffer in use is stored).
Note: At the first scan during power up, make sure to set it to “0” by using the user program. After that, the reg-
ister is used by system. Do not change the value thereafter with the user program.
( 12 ) Reserved by System 2 (PARAM13-PARAM16)
Used by system. Never change this value with the user program, etc.
