Figure 7.23: Ladder Diagram for On/Off Control
Now, we can use GCL logic to achieve the same control operation. Two
logic rules are used. The complete logic architecture is shown by Figure
7.24 below:
Figure 7.24: GCL Logic for On/Off Control
After you load the example project file, you can find that it uses rule 1
and rule 2. One output of rule 1 and one input of rule 2 are assigned to the
same internal flag: Flag 0. This can combine 2 or more logic rules
together, that we call it Logic Cascade (Please refer to Section 7.4.1). We
have configured the condition for DI 1 input as False, so the DI input
value is inverted before entering the AND operator of rule 2. The GCL
logic architecture is similar to the PLC ladder diagram.
3. Sequential Control (Turn On in Sequence and Remain On)
In this kind of application, several digital outputs will be activated in
sequence and latch their values. In the example project we provide, DO 0
~ DO 5 will sequentially be controlled to change their status. The time
chart for this application can be shown by Figure 7.25 below:
