Display Configuration Using Syscon
The user must determine and set up the values described in the table below, for each selected
parameter.
This value indicates
that a default
parameter index 14
and the sub-index 2
of the transducer
block – LD302 are
set as monitoring
Index 14 represents
the LD302 transducer
block output. It is a DS-
64 type (DS-64)
variable, i.e., status –
float value. The sub-
index indicates the
item’s data structure,
for example, 1 selected
the status and 2
selected the
value.
When the parameter is
sample, i.e., not a data
structure, there is no
need to configure the
sub-index.
