Description
This is a general-purpose block for configuring a binary input hooked to a Digital I/O module.
The
Channel is one of the eight inputs available on the module (see Appendix C: I/O Modules).
A processing block such as Measure or Average is used to request data of this block, unless
Event is checked. With Event checked, the output will update on change of state. Use “Edge” to
determine which edge of the state change to trigger (Rising = Low
→
High, Falling = High →
Low, Both = either direction).
The Filter parameter can be used to eliminate false state transition detections due to noise. The
Filter value should be a number between 0 and 255. The higher the number, the longer the new
state change must exist for the change to be seen by the digital I/O module. Each increment of
the filter value represents about 0.5ms of time.
If this block is used in an EZSetup measurement with the Event checked, this will force ALL
measurements to occur when an Event occurs. So, for example, if you had an EZSetup
measurement schedule with the BinIn block and a sdi-12 sensor, every time the BinIn detected a
change of state, the SDI-12 sensor would also be measured.
If Invert is checked, the output from this block will be the inverted value of what is seen at the
channel (e.g., if the input is grounded, a binary 1 is output instead of a binary 0).
Input states are:
0V = binary 0
>2.5V = binary 1
