Real Time
This block of two 32-bit registers [one for date (MMDDYY) and one for time (HHMMSS)] is used to set the instru-
ment’s internal clock. To set the time, write all registers in a single message. See Command Registers, page 11 for a
list of commands.
Date and time can also be read in the holding register groups as floating-point data. These read-only values are set at the
factory and stored in the IEEE 754 single precision floating point format in two 32-bit registers. Only the integer portion
of the floating point value is used to represent the date or time. The first register defines the date in MMDDYY format.
The second register defines the time in HHMMSS format.

Triggered Registers
The Scanner 3100 triggered registers store volumes, averaged values, and flow times since the last triggered archive was
captured. The Scanner 3100 can be configured via the web interface to automatically create triggered archives based on
a variety of modes (log on real time period, periodically, on device alarm, or on digital output) or to support PID tun-
ing when an analog output is configured as a PID controller. Via Modbus, a user can also manually publish a triggered
archive by writing a value of 500050 to the command register. See Command Registers, page 11 for details and addi-
tional triggered archive commands.
Interval/Daily/Event Pointer Registers
These registers provide an index of the last record that was stored in the log data. These values start at 1 and increment
with each newly created log. When the maximum number of records is reached, the pointer resets to 1 and starts incre-
menting again.
Device Status
The Scanner 3100 provides 32 user-configurable alarms that can be assigned to a wide variety of system, device, and
