Security
The AcquiSuite has three levels of security. These are “operator”, “user” and “admin”. When using a browser to access the
AcquiSuite, basic http authentication is used to prompt your browser for a username and password. The admin account uses
“admin” as the default password. To change the password, select the Accounts menu from the left side tree display. Next,
select the account name. Click the “Change Password” button to set a new password for the selected account.
admin
: This account has full access to modify any of the system settings. The default password is “admin”.
operator
: This account may view settings, however may only change modbus alarm ranges and device names.
user
: This account can view some system settings including the modbus device status pages and can change nothing.
When using FTP to access the AcquiSuite, you may use the admin account username/password for read-only access. Log
information is stored in /var/log/modbus. For read-write-delete access, use the login name “root” and the admin password.
The three usernames specified are not able to be changed or renamed, nor can arbitrary usernames be added to the
AcquiSuite. Access is only controlled by setting the password for the three existing usernames noted above.
The “operator” and “user” accounts are disabled by default. These accounts are activated when you first set a password for
each.
Modbus
Modbus Device List
The AcquiSuite automatically searches for Modbus devices on the RS485 serial loop. The Modbus Device List page will
show a listing of all the currently detected or configured devices the AcquiSuite has found. The device list will show the
Modbus address number, status (OK, Error, Alarm, Unconfigured), the device name (user specified) and the device
identification string.
Click on the Modbus address number for any of the devices for specific device details
Note: not all Modbus devices have built in driver support in the AcquiSuite. If a device appears in the list with “Unknown”
in the status column, you may need to upgrade the firmware on the AcquiSuite to access the device. At the bottom of the
device list page under the Type column, a link is shown that will show all the Modbus devices with built in driver support
provided in the firmware. Use the System/Firmware update page to check for newer versions of the firmware. The
Obvius.com website faq also has a list of supported Modbus devices. Modbus devices that are not supported by built in
drivers may be configured using the Modbus Framework feature in the AcquiSuite.
At the bottom of the device list, there is an option to allow you to rename all the devices listed. This is useful for initial
deployments. There is also a troubleshooting link that will look for common configuration problems and alert you to the
appropriate solution.
