Gcl Rule Execution Sequence - Advantech ADAM-6217 User Manual

Note! When you use Internal Flags (AuxFlag) as the inputs of GCL logic rules,
you can dynamically change the flag values in the online monitoring win-
dow of ADAM.NET Utility. Simply double click the input icons repre-
sented the internal flag, and you can see the flag values change from
True to False, or from False to True.

GCL Rule Execution Sequence

There are 16 logic rules on one ADAM-6200 module. As below, you can see the exe-
cution flow for one cycle and there are 3 groups for one cycle: Input Condition +
Logic, Execution, and Output .All the Input Condition + Logic stages of rules which
are enabled will execute sequentially first. Then, all the Execution stages of rules
which are enabled will be executed in sequence. In the end, all Output stages of rules
which are enabled will be executed in order. For some advanced applications, you
may combine different rules together by Logic Cascade architecture. For example,
the output of rule 1 is connected to the input of rule 2, by assigning to the same inter-
nal flag. Based on the execution flow mentioned above, the Input Condition + Logic,
Execution and Output stages of rule 1 will be executed sequentially. Therefore, the
output of rule 1 will be updated at the last stage (Output stage) in the first cycle, and
the input of rule 2 can detect the change of output of rule 1 in the next cycle.
