Options digital_channel
Specify the Digital channel number, for example, d2.
alarm
Configures alarm settings when the Digital input trigger is activated.
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.
email
Sends an email alert to an email account(s) set up in the Server settings (the Line Email
Alert settings are not used with this feature) when an alarm is triggered or cleared. The
email alert data includes the severity level and the value that caused the alarm to trigger
or clear. The
Email Alert is associated with Level Critical.
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.
