Local Frequncy Input Channel (DI_Frequency)
After you choose DI_Frequency as input mode, select the channel by the
Channel combo box. The frequency value of the frequency input channel
will directly be the input of condition. Like the Counter Input condition,
select the appropriate condition for that input channel by the Condition
combo box and the Value text box. The condition will compare the fre-
quency value read from the frequency input channel and the value set by
the Value text box. If condition is satisfied, the condition result is logic
True. Otherwise, the condition result is logic False.
Internal Timer (Timer)
There are 16 local timers on one ADAM-6000 module. After the timer is
started, its value represents how long the time has passed. Here, you can
read the timer value and use it as input condition. After you choose
Timer as input mode, select appropriate timer by the Index combo box.
(From timer 0 to timer 15) Then you can define the condition by the Con-
dition combo box and the Value text box (unit: 0.01 second).
Only when the condition is met, the condition result is logic High. For
example, if you choose
>=
in the Condition combo box and type 500 in
the Value text box, it means the condition result will remain logic Low
until the timer value is greater 5 second (meaning 5 second is passed).
After 5 seconds is passed, the condition result will become logic High.
Internal Flag (AuxFlag)
There are 16 internal flags on one ADAM-6000 module. The data type of
internal flag is digital, meaning its value is either logic True or logic
False. You can read the internal flag value and use it as input condition.
After you choose AuxFlag as input mode, select appropriate internal flag
by the Index combo box. (From flag 0 to flag 15) Then you can define
the condition by the Condition combo box.
If you choose True in the Condition combo box, it means only when the
internal flag value equals to logic True, the condition result is logic True.
If you choose False in the Condition combo box, only when the internal
flag value equals to logic False, the condition result is logic True.
You can use internal flag to implement logic cascade or logic feedback.
Refer to Section 7.4 for more detail about how to achieve this.
