10.3.2 Output Parameters for the Array Compare Instruction
This table lists the outputs for the ARC instruction and the variable type and data
type/range that each output supports.
Parameter Description Variable Type Data/Type Range
ENO Use this output as the input to another instruction for
easily chaining multiple instructions. This output follows
the state of EN unless an error occurs.
DN This output becomes true when:
D The instruction has operated on the last array eleĆ
ment.
D A comparison operation results in a false condition,
even though all elements within each array have not
been evaluated.
D An error is encountered during the first scan.
DN is false when EN is false.
Connect a contact, coil or Boolean parameter of
another instruction.
Q This output becomes true when the operation is comĆ
plete (DN is true) and the result of the comparison is
true.
Otherwise, the Q output is false.
Index Enter the name of a simple variable in which you want
to store the index that was operated on during the last
scan.
D simple
D element of an array D integer
D double integer
The range is
0 to 99999
