Set IOChannel

Set IOChannel Digital Output

trigger

When the trigger condition is met, triggers the specified alarm action. Triggers can be:

z Disabled—No alarm settings. This is the default.

z Inactive—When the expected Digital input is active, going inactive will trigger an

alarm.

z Active—When the expected Digital input is inactive, going active will trigger an

alarm.

clear

Specify Manual to manually clear an alarm. Specify Auto to automatically clear the

alarm when the trigger condition changes; for example, if the

Trigger is Inactive and

the alarm is triggered, once the input becomes active again, the alarm will be cleared

when

Auto is set. The default is Auto.

syslog

Sends a message to syslog when an alarm is triggered or cleared. The syslog entry

includes the severity level and the value that caused the alarm to trigger or clear. The

syslog message is associated with

Level Critical.

snmp

Sends an SNMP trap when an alarm is triggered or cleared. The trap consists of the

severity level and whether the alarm was triggered or cleared.

description

Provide a description of the channel, making it easier to identify. The channel

description can be up to 20 characters.

invert-signal

Inverts the actual condition of the I/O signal in the status; therefore, an inactive status

will be displayed as active.

latch

Latches (remembers) the activity transition (active-to-inactive or inactive-to-active).

The latched status is maintained until it is read. Once it is read, it will revert to the

current status. The default is disabled.

Description Sets the Digital output channel settings.
