Anybus M-Bus to Modbus-TCP Gateway User Manual Doc: HMSI-27-300, Rev: 1.10
6.2.3 No write access to the web interface
The web interface is accessible but the settings cannot be changed.
1. Check if you are logged in as a user with write access (see 3.1.6
User tab). If not, log out and log
in as another user with write access.
2. Write access is only allowed for one of the currently logged in users. If another user with write
access is already logged in, they will have to log out before you can log in with write access.
If you are the only logged in user that has write access,
- Check if you have another active session in a different browser or browser tab.
- A previous session may not have been closed properly. Try clearing the web browser cache
(see the documentation for your browser).
3. Log in as admin and edit the access rights for the user.
6.2.4 Web session is unexpectedly terminated
If the web session is unexpectedly terminated, this may be due to a connection timeout. The timeout
limit can be increased from its default value by editing the system parameter WEBCOM_TIMEOUT
(see 7.4.1
System configuration file).
A timeout may also occur if the gateway is currently busy with the collection and transmission of meter
data, which takes priority over web communication.
6.2.5 FTP login failure
FTP login fails, or the file list is empty.
1. Log in to the web interface as admin and check the FTP user password.
2. Try logging in to the FTP server as admin and check the communication log.
3. If the login was successful (no errors in the communication log) but the files in the gateway are
not visible, try using your FTP client in FTP passive mode.
(Passive mode can be selected at login in the CHIPtool FTP client.)
4. Check the network configuration (see 2.2
Network configuration) and that the gateway is not
blocked by firewall settings. If you are unsure, contact your network administrator.
