The Wbm - Siemens SIMATIC RF166C Operating Instructions Manual

Note
Connection to the communication module cannot be established
If a connection to the communication module cannot be established, check the following
points:
• Make sure that all cables are correctly connected.
• Ensure that the communication module has started up ("RUN" LED lit/flashing green).
• Check the IP addresses of the PC and the communication module as well as the subnet
mask. Both IP addresses must be located in the same subnet.
• Make sure that the connection is not blocked by a firewall.
• Use a ping request to check the connection between the PC and the communication
module.

The WBM

You can use the WBM to configure the SIMATIC RF166C communication modules.
NOTICE
Security recommendation: Enable user management
After starting the WBM the first time, no user management is enabled. To make sure that
no unauthorized persons can access the communication module settings, we recommend
that you enable the user management and create new user profiles after the first login.
Note that user administration can only be enabled by an administrator.
During your first login as administrator (User: admin / password: admin), you must change
the password for security reasons.
For further information on logging in to WBM and creating/deleting user profiles, refer to the
section "The "User management" menu item (Page 89)".
NOTICE
Access to the communication module
Note that you can simultaneously access a communication module via two WBM clients
(Web browsers) but this is not recommended.
If changes are made when two WBM clients are accessing a reader at the same time, this
can lead to errors in the configuration or to an undesired result.
When you have created new user profiles you need to log in with one of these user profiles
when you restart the WBM.
