G.2 Message Receive Function (MSG-RCV)
A-116
Example: “Writes to multiple holding registers” with offset is received:
When “writes to multiple holding registers” with offset is received in MEMOBUS protocol, various setting values and the
relationship with the data of remote equipment are as follows:
• Description of the MSG-RCV function in ladder program
• Parameter list setting of the MSG-RCV function
Note: IN: Input, OUT: Output, SYS: For system use
