Figure 7.27: Time Chart for 12 DI to 1 DO
You can simply implement one AND logic operator to achieve this con-
trol system. However, since one logic rule only has three inputs, we need
to use Logic Cascade function to have 12 inputs. There are two ways to
achieve Logic Cascade:
• Select SendtoNextRule in Execution Stage of one logic rule. It will
combine this logic rule to the next logic rule. (Refer to Section 7.3.3)
• Assign output of one logic rule and input of another logic rule to the
same internal flag, combining the two logic rules together. (Refer to
Section 7.4.1)
With the first method, the two logic rules must be next to each other. For
example, rule 1 and rule 2 can be combined together. But you cannot
combine rule 1 and rule 3. There is no such limitation if you use the sec-
ond method to combine two different logic rules. Using the second
method, you can even combine two rules on different modules together.
Here, this example project adapts the first method for Logic Cascade. So
the GCL logic architecture can be shown by Figure 7.28 below:
