Product Introduction
Network security
The Web-IO has an internal firewall. All available network
accesses are configurable and must first be enabled by the
administrator. By default only browser access, inventorying
via Wutility, and the port for initializing firmware updates are
enabled. DHCP is also enabled.
You can explicitly specify for all communication paths whether
the outputs may be accessed.
A list of the currently open TCP and UDP ports can be found in
the navigation tree under
Port list.
Access rights
The Web-IO is configured and operated from the browser. There
are three authorization levels for access:
Guest
The guest has read-access to the status of Input, Counter and
Output without logging in.
User
A user can switch the output after logging in with a password if
it is enabled for access via the browser.
Administrator
After logging in with a password the administrator has
unrestricted configuration and access rights.
By default no passwords are assigned for the Web-IO. Simply
click on the Login button.
After login the navigation tree on the left side can be used to
open the enabled configuration areas. For help and information
about the respective configuration possibilities click on the Info
buttons on the right side.
Clicking on the Apply button makes the settings immediately
effective.
