Configuration and Activation 6-9
Note: The Scan and Fast designations apply when
implementing the Dual Data Rate feature in MLI. The
Scan rate also pertains to applications involving Modbus
and Telog
® Ru-33 operations.
 Fast Select the accelerated rate at which you want the
monitor to take and store readings once the threshold
defined in MLI has been exceeded. The monitor will
remain in this state until the flow conditions at the
monitoring point return to normal, as defined in MLI.
 Scan Select the interval at which you want the monitor to
take readings and verify whether an event threshold has
been exceeded. The readings are not stored or logged as
historical data for future data collection. Instead, the
readings taken at a particular date/time in the interval
remain available (or persist) until they are overwritten by
the readings taken at the next consecutive date/time in the
interval. For Modbus applications, the Scan rate also
represents the rate at which Modbus updates the data
available to the RTU or the Telog Ru-33. The RTU
requests this data from either the EMUX (Buffered Mode)
or the monitor (Passthrough Mode). The Telog unit
requests this data directly from the monitor. Please note
that the EMUX, when in use, automatically retrieves the
available (i.e., persisting) data from the monitor every
minute. When using the Telog Ru-33, IETG recommends
applying the same interval for both the scan rate in the
monitor and the rate at which the Telog unit requests data
from the monitor
12. (applies only to Modbus/Telog Ru-33 applications) Select the
Enable checkbox and modify the following parameters in the
Modbus section as necessary:
 ID Enter the slave address number from 2 to 57, 59 to 96,
or 98 to 247 you want to be used when facilitating
communication between the EMUX and RTU or the
FlowHawk and the Telog Ru-33. The 1, 58, and 97 are
used for other addressing purposes and will not be
recognized. Choose a number that is unique from the other
