Table 18 – LB(x-3) Condition Evaluation Results
2.5.2.
Table Selection
In order to, determine if a particular table will be selected, logical operations are performed on the
results of the conditions as determined by the logic in Section 0. There are several logical
combinations that can be selected, as listed in Table 19. The default value for object 3x02h
LB(x-3)
Function Logical Operator
is dependent on the sub-index. For sub-index 1 (Table A) and 2 (Table
B), the
‘Cnd1 And Cnd2 And Cnd3’
operator is used, whereas sub-index 3 (Table C) is setup as the
‘Default Table’’
response.

Table 19 – LB(x-3) Function Logical Operator Options
Not every evaluation is going to need all three conditions. The case given in the earlier section, for
example, only has one condition listed, i.e. that the Engine RPM be below a certain value. Therefore,
it is important to understand how the logical operators would evaluate an Error or N/A result for a
condition, as outlined in Table 20.
