Other Functions Chapter 8
If an Exclusive Owner connection has been set up between a Logix controller and
the PowerMonitor 5000 unit, configuration of the power monitor is permitted
only through the controller. Attempts to change configuration by using the web
interface or other means returns an ownership conflict error.
The PowerMonitor 5000 unit does not have a ‘backdoor’ password. If security
accounts are inadvertently deleted or login credentials are lost, connect to the
power monitor by using USB and log in to the USB Admin account to edit and/
or create new accounts to restore security access.
Security configuration using messaging on the optional DeviceNet network is
not supported.
Date and Time Functions The PowerMonitor 5000 unit internal clock and calendar is used in demand
metering and data logging functions. A number of user-selectable options are
available for synchronizing and controlling the internal clock and calendar.
Daylight Saving Time is disabled by default. With DST enabled, the power
monitor internal clock advances by one hour on the start date and hour specified,
and is set back by one hour on the return date and hour specified. The defaults
represent the common DST start and return date/times in the use in the United
States since 2006. The DST function also adjusts the network-time sync offset
when used.
