D8092-D8095 Default Gateway (Current Data) Read only
Default gateway of the SmartAXIS is stored in the special data registers as shown below.
Example) Default gateway: aaa.bbb.ccc.ddd
D8092=aaa, D8093=bbb, D8094=ccc, D8095=ddd
D8104 RS232C Control Signal Status (Port 2 and Port 3) [Ladder program only]
RS232C control signal status of port 2 and port 3 is stored in D8104.
This function cannot be used when FBD program is selected as the programming language.

This function cannot be used when FBD program is selected as the programming language.
D8106 RS232C DTR Output Control Signal Option (Port 2 and Port 3) [Ladder program only]
Special data register D8106 is used to control the DTR (data terminal ready) signal to indicate the SmartAXIS operating status or

D8110-D8121 Connection (1 through 3) Connected IP Address
The IP address of the remote host accessing connection 1 through 3 is stored in special data registers.
Example) Connection 1 Connected IP Address: aaa.bbb.ccc.ddd
D8110=aaa, D8111=bbb, D8112=ccc, D8113=ddd
D8130-D8132 Connection Connected Port Number
When connections are established with other network devices, the port numbers of the connected network devices are stored in
these special data registers.
For FBD, a linear transformation can be configured for the analog input (AI). Even when a linear transformation is configured for
AI, the special data registers store the analog values (0 to 1000) before the linear transformation.
