G.2 Message Receive Function (MSG-RCV)
A-112
[ d ] PARAMETER (parameter)
When RESULT (process result) = 4 (FMT_NG: parameter format error), an error code in the following table is output.
Otherwise, the connection number is output.
( 4 ) Connection Number (PARAM02)
Refer to G.2.4 Function Setting and Parameter Details for MEMOBUS and Extended MEMOBUS Protocols.
( 5 ) Data Size (PARAM06)
A data size requested from the transmission side is output.
In case of non-procedure 1, the number of words is output.
In case of non-procedure 2, the number of bytes is output.
( 6 ) Register Offset (PARAM12)
Specify an offset address for the reception side data address.
The address for the reception side will be displaced by the number of words designated by the offset.
Note: 1. For more information, refer to G.2.8 Relationship between Data Address, Data Size, and Offset for
MSG-RCV Function.
2. The offset cannot be a negative value.
In case of non-procedure, received continuous data is stored in the M register. Setting the register offset enables you to
specify a start address of the M register as a storage area.
Example: When specifying MW01000 for the start address of the M register for storing received data:
PARAM12=1000
RESULT (process result) Code (Hex) Meaning
