Output Mode
The “Output Mode” radio buttons allow an operator to define if the output relay should be driven to its
active state or its normal state when an output is generated.
1. Driving to the active state opens the normally closed contact and closes the normally open contact.
Typically, this is used to turn on an alarm or device. Click on the A radio button to select the active
state.
2. Driving to the normal state closes the normally closed contact and opens the normally open contact
(the normal or idle state of the relay). Driving an output to the normal state can be used to turn off
an output that was driven to its active mode. Click on the N radio button to select the normal state.
Enable Outputs
The “Enable Outputs” and “Event Messages Only” radio buttons work in conjunction with each other.
One or the other can be selected, not both.
1. Click on the Enable Outputs radio button to select if the input events in the I/O link should drive an
output relay.
2. Click on the Event Messages Only radio button to select if the input events in the I/O link should
just generate an event message.
Event Messages Only
See Enable Outputs.
Link Sounds Alert
Links a sound alert to the I/O link that will annunciate when in monitor mode.
Output Alarm Type
The “Output Alarm Type” radio buttons allow an operator to select how long an output is driven when
activated. There are three output modes from which to choose.
• Click on the Timed radio button to make the output relay active for the period of time defined in
the Seconds field. To set a time in the Seconds field, either double-click in the field and directly
type in a value (255 seconds maximum) or use the arrows to scroll up and down and select a
time.
• Click on the Follow radio button to make the output relay follow the state of the input. The output
will stay active as long as the input is in its active state. When the input becomes inactive, the
output becomes inactive. A Follow output uses two links internally which reduces the total number
of available links.
• Click on the Latched radio button to have the output state triggered by the input state. When the
input becomes active, the output becomes active and stays active until manually inactivated by an
operator (using the manual output control commands given in the next section or by another link).
Time Zone
The “Time Zone” field allows an operator to assign a time zone to the I/O link. The entering or exiting
of the time zone time period does not
activate the link; the link will operate only during the time period
defined by that time zone.
1. Click on the arrow. A list of all available time zones appears.
2. Scroll through this list and click on the desired time zone. If the link must be active all the time,
click on the Always time zone.
