Sends the request message Word Block Data Read.
The node number specified in the FINS command block is used as the read
source node number. Specify the FL-net Unit that will execute the FINS com-
mand in the control data (network address, node address, unit address) of the
CMND(490) instruction. The FINS command can be executed from the CPU
Unit of the FL-net Unit or through a FINS network on another layer.
