(Note 1) For IPv4, a decimal number is stored in each area of the storage.
Example) When the master unit IP address is 192.168.1.5, the IP address is stored as follows:
[D]=U192, [D+1]=U168, [D+2]=U1, [D+3]=U5
(Note 2) The destination varies depending on the setting of the communication method (TCP/UDP) as shown in
the following table.
