During operation, the option board uses the selected signals and applies the selected logical function to determine the state of the
output. If the result of the logical function on the actual state of the selected signals is "true", the output is active. If the result is
"false", the output is inactive.
EXAMPLE 1 (USING GROUP 2):
Selected signals: SLS 1 Reached, SSM Below Min Limit
Logical function: OR
Table 7: Example 1
State of the signals
SLS 1 Reached = 0
SSM Below Min Limit = 0
SLS 1 Reached = 0
SSM Below Min Limit = 1
or
SLS 1 Reached = 1
SSM Below Min Limit = 0
SLS 1 Reached = 1
SSM Below Min Limit = 1
EXAMPLE 2 (USING GROUP 2):
Selected signals: SLS 1 Reached
Logical function: NOR
Table 8: Example 2
State of the signals
SLS 1 Reached = 0
–
SLS 1 Reached = 1
EXAMPLE 3 (USING GROUP 2):
Selected signals: SLS 1 Reached, SSM Below Min Limit
