Settings for Sending FINS Commands Section 3-4
3-4-4 CMND(490) Setting Example
The designated number of bytes of FINS command data from the first com-
mand word designated by operand S is sent to the designated unit address
via the node address on the network address designated by operand C, and
the response is stored for the number of bytes of data received starting from
D.
In this example, a command (MEMORY AREA READ: 0101 Hex) for reading
D00010 to D00019 of the PLC at node 02 is sent using CMND(490).
D00010: Memory area code (82 Hex), address 000A00
Number of elements read: 10 = 0A Hex
S: First command word
D: First response word
C: First control word
S: First command word
