14–Discrete I/0

Trigger Evaluation Period

Number Before Output

Reads per Trigger Threshold

Definition: The number of trigger events to examine within the trend analysis

event.

Serial Cmd: <K720,output on,active state,pulse width,output mode,trend analysis

mode,trigger evaluation period,number to output on,reads per trig-

ger threshold>

Default: 0

Options: 0 to 255

Definition: Sets the number of events (matches, mismatches, or noreads as con-

figured by Output On) that must occur before activating the associated

output.

Serial Cmd: <K720,output on,active state,pulse width,output mode,trend analysis

mode,trigger evaluation period,number to output on,reads per trig-

ger threshold>

Default: 0

Options: 0 to 255

Definition: When Reads/Trigger trend analysis mode is enabled, the Reads per

Trigger Threshold value is the minimum number of successful reads

required during a read cycle.

Helpful

Hints:

You can determine the expected number of scans during a read cycle

by multiplying the enabled Number of Scans per second times the

number of seconds in the read cycle. You can also use Quality Output

(see “Quality Output”) to observe the number of successful reads.

Serial Cmd: <K720,output on,active state,pulse width,output mode,trend analysis
