Figure 7.15: Configuration of Logic Rule 3
We use the logic rule 1 to check if AI channel 0 value of the ADAM-6017
is within 3 ~ 5 Volt. Logic rule 2 is used to check if AI channel 1 value is
within 3 ~ 5 Volt. The comparison result of logic rule 1 and 2 is assigned
to internal flag 0 and 1. The logic rule 3 read the value of these two inter-
nal flags and use the OR logic operation to define the output of digital
output channel 0. You can find that we have built the logic architecture as
shown by Figure 7.12 by the internal flag.
Distributed Logic Cascade
Logic Cascade function is not limited on one single module. Since you
can define the internal flag on another module, the logic cascade structure
can be across different modules. Take the previous application as exam-
ple, now you can define the logic rule 1, 2, 3 are running on module A, B
and C. Then the logic structure becomes across three ADAM-6000 mod-
ules, and we call it Distributed Logic Cascade. Refer to Figure 7.16 for
the logic architecture. And the configuration for the three logic rules can
be shown by the Figures 7.17 ~ 7.19 below.
