FINS commands can be issued to the Loop Control Unit by one of the
following two methods:
1) By the CMND (DELIVER COMMAND) instruction from the CPU Unit
2) By the Host Link or the networked host computer
FINS commands can be issued to the Loop Control Unit by executing the
CMND (DELIVER COMMAND) instruction in the program on the CPU Unit or
networked PC (CPU Unit) on which the Loop Control Unit is mounted.

Response data
When this method is used, the user need not consider the frame format of
the FINS command. Basically, the user executes the following.
1. Store the data in the command format of the FINS command to an I/O
memory area such as Data Memory. (S onwards: command data.)
2. Store the number of send data bytes or the addresses of the send
destination to the I/O memory area such as Data Memory. (C to C+5:
control data)
Note When the FINS command is issued to the Loop Control Unit mounted on the
self node, set the send destination network address to 00 Hex (self network)
and the send destination node address to 00 Hex (self node).
3. Specify S (first command word number), D (first response word number)
and C (first control data word) as the operands of the CMND (DELIVER
COMMAND) instruction, and execute the CMND instruction.
