5.6.4 AI Function Block Parameters
Parameters of the six aI function blocks can be
read and written from the host. For a list of block
parameters in each RotaMaSS, refer to ap-
pendix 1, “List of Parameters for Each Block of
RotaMaSS.” the following describes important
parameters and how to set them. For a model
with an option adding a PID function block and
LM functionality, see appendixes 5 and 6.
MOdE_BLK:
Indicates the three types of function block
modes; out_of_Service, Manual, and auto. In
out_of_Service mode, the aI block does not
operate. the Manual mode does not allow val-
ues to be updated. the auto mode causes the
measured value to be updated. under normal
circumstances, set the auto mode to take ef-
fect. the auto mode is the factory default.
CHANNEL:
this is the parameter of the transducer block
to be input to the aI block. aI1 block is as-
signed mass flow rate. aI2 block is assigned
volume flow rate. aI3 block is asigned den-
sity. aI4 block is asigned temperature. aI5 is
assigned concentration measurement. aI 6 is
assigned net flow rate. Do not change this set-
ting.
Xd_SCALE:
Scale of input from the transducer block.
Changing the unit (can be set only in mass
flow rate) also causes the unit within the trans-
ducer block to be automatically changed. (the
unit is automatically changed according to the
unit selected by aI 1, 2, 3, 4, 5, 6. aI5.XD_
SCaLE.unIt_InDEX depend on customer’s
spec.) units which can be set by XD_SCaLE
are shown table 5.16.
note: With the same setting, some units are represented
differently between the F ounDatIon Fieldbus com-
munication type and the HaRt communication type of
a RotaMaSS. Each unit enclosed in brackets above
shows the unit for the HaRt communication type of
RotaMaSS corresponding to the preceding unit (for
the Foundation Fieldbus communication type).
