“
Table X
– Condition Y Operator
”. Setpoint options are listed in Table 27. Condition
arguments are selected with “
Table X
– Condition Y Argument Z Source
” and “
Table X
–
Condition Y Argument Z Number
” setpoints. If ‘
0
– Control not Used
’ option is selected as
“
Table x
– Condition Y Argument Z Source”
the argument is interpreted as 0.
Table 27. Table X
– Condition Y Operator Options
0
=, Equal
1
!=, Not Equal
2
>, Greater Than
3
>=, Greater Than or Equal
4
<, Less Than
5
<=, Less Than or Equal
The three conditions are evaluated and if the result satisfies logical operation defined with
“
Logical Operator X
” setpoint, given in Table 28, the associated Lookup Table is selected as
output of the Logical block. Option ‘
0
– Default Table
’ selects associated Lookup Table in all
conditions.
Table 28. Table X
– Conditions Logical Operator Options
0
Default Table (Table1)
1
Cnd1 And Cnd2 And Cnd3
2
Cnd1 Or Cnd2 Or Cnd3
3
(Cnd1 And Cnd2) Or Cnd3
4
(Cnd1 Or Cnd2) And Cnd3
The three logical operations are evaluated in order and the first to satisfy gets selected, thus if
Table1 logical operation is satisfied, the Lookup Table associated with Table1 gets selected
regardless of two other logical operations. In addition, if none of the logical operations is
satisfied the Lookup Table associated with Table1 gets selected.
3.12 Global Parameters
The
Global Parameters
functional block gives the user access to a set of global constants, unit
supply voltage and the microcontroller internal temperature.
Figure 6. Global Parameters Function Block
The function block provides two configurable global constant signals. It also provides the
“Supply Voltage” signal presenting the controller supply voltage in [V] and the “Microcontroller
Temperature
” signal presenting the internal microcontroller temperature in [°C].
