Connection Settings
This section describes the configurations of the SmartAXIS module for client/server connections..
Applications
The SmartAXIS supports Ethernet communication functions with a maximum of three connections. Using those connections,
maintenance communication, Modbus TCP communication, user communication, and remote I/O communication can be used.
Those communications can be configured in the Function Area Settings dialog box.
Description of functions
The SmartAXIS has a maximum of three connections for the maintenance communication server, user communication server,
Modbus TCP communication server, user communication client, Modbus TCP communication client and remote I/O master.
To limit the access to the SmartAXIS, IP address flittering can be used. By specifying the IP address that can access the
SmartAXIS, anonymous access can be prevented.
Connection Status and Connected IP Address
The connection status of connections with remote hosts can be confirmed with special internal relays M8110 to M8112. When a
connection with a remote host is established, the corresponding special internal relay is turned on. When the connection is
disconnected, the corresponding special internal relay is turned off. The IP addresses of the remote hosts can be confirmed with
special data registers D8110 to D8121.
Note: R/W is the abbreviation for read/write. When R/W, it can be read and written. When R, it can only be read. When W, it can only be written.
