14–Discrete I/0

Output Mode

Pulse

Latch Mode 1 (Unlatch on Discrete Input 1)

Latch Mode 2 (Unlatch Opposite Condition)

Latch Mode 3 (Unlatch Enter Read Cycle)

NOTE: All of the Output On modes are inhibited when any Output on Warning is

active for Output 1 (see <K713> command).

Definition: Sets the condition in which the discrete output is de-activated.

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

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

threshold>

Default: Pulse

Options: 0 = Pulse 1 = Latch Mode 1

2 = Latch Mode 2 3 = Latch Mode 3

Definition: This is the default mode of operation in which the programmable output

is activated when the Output On condition has been met and held

active for the duration of the selected pulse width.

Definition: The programmable output is active when the Output On condition has

been met and held active until the discrete Input 1 has been activated.

Definition: The programmable output is activated when the Output On condition

has been met and held active until the opposite condition selected

under Output On has been met.

For example, if Noread is enabled under Output On, the programma-

ble output will go active upon a noread and remain active until the

opposite condition, a good read, occurs.

Definition: The programmable output is active when the Output On condition has

been met and is held active until a new read cycle begins.
