Connection Settings
This section describes the configurations for client/server connections of the Web server CPU module.
Applications
The Web server CPU module supports Ethernet communication functions with a maximum of 11 server connections and
a maximum of three client connections. Using those connections, maintenance communication, user communication,
and Modbus TCP communication can be used. Those communications can be configured in the Function Area Settings
dialog box.
Description of functions
The Web server CPU module has a maximum of three connections for the maintenance communication server as
standard. WindLDR on a PC can monitor, download, or upload the user program using the standard maintenance
communication server.
In addition to the standard maintenance communication server, the Web server CPU module has eight server
connections that can be used for maintenance communication, user communication, or Modbus TCP communication.
Even when the maintenance communication is configured for additional server connections, the user program cannot be
downloaded or uploaded through those server connections. When Modbus TCP is configured, the same port number can
be configured in multiple server connections so that multiple Modbus TCP clients can access the Web server CPU module
through the same port.
To limit the access to the Web server CPU module, IP address flittering can be used. By specifying the IP address that can
access the Web server CPU module, anonymous access can be limited.
Programming WindLDR
1. Select Configuration from the WindLDR menu bar, and then click Connection Settings.
