Description
Hardware identifier for TIO module from hardware
configuration
Number (0 ... m) of the digital input of the connected TIO
module
Specify the edges for which time stamps are detected:
0 : Invalid
D
1: Two rising edges
2: Two falling edges
3: Rising and falling edge (order depending on
occurrence)
4: First rising, then falling edge
5: First falling, then rising edge
6 to 255: Invalid
EdgeSel can be changed during normal operation.
Status of digital input.
If an inversion of the digital input is configured, this
parameter is inverted as well.
Time stamp: Time at which a positive edge was
detected.
Exception:
EdgeSel = 2: Time at which a falling edge has been
multiple
detected (if falling edges have occurred during
the application cycle).
Time stamp: Time at which a falling edge was detected.
Exception:
EdgeSel = 1: Time at which a rising edge has been
multiple
detected (if rising edges have occurred during
the application cycle).
Counter: Is incremented with each new, valid time stamp
at a positive edge. The counter is reset with each CPU
startup.
Counter: Is incremented with each new, valid time stamp
at a falling edge. The counter is reset with each CPU
startup.
Counter: Number of edges for which no time stamp
could be saved. The module can count a maximum of
seven edges per application cycle. The counter is reset
with each new application cycle.
