factthat the default PIN still matches the criteria for “Read / Write” which will accidentally promote the
user. Obvius Ally Configuration Console and the Web App disallow this condition but remote programmers
using direct register access may create this condition.
READ ONLY PERMISSION REGISTER
Configuring the meter for a Read Only user allows data or configuration items to be viewed but not
changed. This level of authorization might be appropriate for general end users such as building owners
who may not be aware of the details of the installation. It is recommended to use Obvius Ally
Configuration Console to configure permissions although it is also possible to set up a Read Only PIN using
the Web App if a Read/ Write PIN has already been entered (either through the LCD or the Web App
itself).
READ/WRITE PERMISSION REGISTER
Read/Write permissions allow users to read and write configuration items and to reset the PINs. This level
of authorization will be required by any technician or user who needs the ability to correct setup errors in
the meter. The default PINs [0000] allow new users to reset the Read / Write PIN from either the
AcquiSuite™ Ally Web App or Obvius Ally Configuration Console. Permissions cannot be set through the
LCD interface.
READING PINS OVER MODUS OR BACNET
Obvius Ally Configuration Console can be used to directly report the Read Only and Read/ Write PINS
under the Advanced Tab (passwords). The value reported by Obvius Ally Configuration Console is the
value as entered in the web page or LCD interface.
PINs are also accessible as registers, but are encoded so that reading the value of the register through
an RTU does not inform a user what the password is. This feature allows DENT Instruments to support
looking up forgotten PINs, if network access is available.
OBVIUS ALLY CONFIGURATION CONSOLE UNRESTRICTED ACCESS
The Obvius Ally Configuration Console software tool can be used to read & write configuration
information to the meter without entering credentials.
• Obvius Ally Configuration Console is the preferred tool for setting up access
restrictions because it allows users to test the function of the PINs without
locking themselves out from the ability to change the PIN, a frustrating catch
