∗ 1: Set to 00 Hex as destination is self node.
∗ 2: Example w here unit number of Loop Control Unit is 01. Set 11 Hex obtained by adding 10 Hex to 01.
4. When the FINS response frame is returned from the Loop Control Unit,
data conforming to the response format is stored to the response
address.
5. The response is then read when the Network Communications Enabled
Flag corresponding to the communications port number to be used turns
ON.
For details, refer to items describing the CMND (DELIVER COMMAND)
instruction in the Communications Commands Reference Manual (Cat.
No. SBCA304) or the CS1 CPU Unit Command Reference Manual (Cat.
No. SBCA-302).
To read ITEM007 (PV) at block address 001 (e.g. in the case of Basic PID)
on the Loop Control Unit currently mounted on the self node (when the unit
number of the Loop Control Unit is 01)
