Figure 4.4 Overview of Totalizer Block
Totalizer block parameters can be read or set from the
host. The AXF contains three Totalizer blocks. For a
list of the parameters of blocks held by the AXF, see
Chapter 9.
TARGET_MODE, MODE_BLK:
Indicates the three types of function block modes; Out
Of Service (O/S), Manual, and Auto.
TARGET_MODE indicates what mode of operation is
desired for Totalizer block. In Out Of Service mode
(O/S), the TOT block does not operate. The Manual
mode does not allow values to be updated. The Auto
mode causes the measured value to be updated. Under
normal circumstances, set the Auto mode to take effect.
The Auto mode is the factory default.
CHANNEL:
This is the parameter of the transducer block to be
input to the Totalizer block. Totalizer block is assigned
to flow rate.
UNIT_TOT:
This is the parameter of the unit of the totalized value
coming from the transducer block. Totalizer block
doesn’t have the scaling which is similar to AI Block.
Available units for UNIT_TOT are the units shown
below.
