The inputs can be combined in any order. The evaluation is done from left
to right. There is no use of “(“ and “)” to form more complex ordering. The
“0” and “1” values are used for “low’ and “high”. If the result of the
combination of signals is “1”, then the DIOHI condition is satisfied. If the
result of the combination is “0”, then the DIOLOW condition is satisfied.
Both the DIOHI and DIOLOW event types can use the logical signal support.

Command: EVENT, DIOLOW, bit-name, settle, holdoff, action
Define an event that looks for a discrete input line to go to a low level.
Parameter Description
DIOLOW
Scan discrete input signal for low condition.
bit-name
Name of discrete input signal to be scanned for low level. (single or multiple
inputs)
settle
Number of clock ticks for the input signal to settle at the low level before
declaring an event.
holdoff
Number of clock ticks for the analog input signal t
o settle at the high level to
be armed for detecting the next event.
