I/O Module Status

This page provides an overview of the current conditions and the status values for the selected I/O module.

Status Tab

The Status tab displays critical information about the point status:

Point Value - The current value of the point.
Point State - The current state of the point.
Point Service - Indicates the current point service of the point. Click to change the point service.
Reliability - Displays the point reliability based on the point state.

Alarms Tab

All alarms affecting the system are listed in a table view. To manage alarms:

Select one or more alarms and click:

Acknowledge to acknowledge the alarm(s).
Remove to delete the alarm(s) from the table. If the alarm condition continues or reoccurs, it will reappear in the table.
Comment to comment on the alarm(s).
Select a single alarm and click Ignore to dismiss the alarm in Tracer Ensemble system:

Data Logs Tab

The Data Logs tab allows you to select data logs for the point.

Click Select Data Points and select one or more data logs. Click View.
Select a predefined date range from the Display Period Length list or click Advanced Display Range to specify precise start and end dates and times.
Click Display User Overrides to display user overrides on the chart.
Click Display Alarm Events to display alarm events on the chart. By default, all alarm priorities are displayed. To customize what alarm priorities display, click Select Alarm Priorities.

Configuration Tab

The Configuration tab allows you to edit the point.

Analog Input

Name: the name of the point (not editable)
Description: Enter a detailed description of the point function. This is an optional configuration.
Referencers and Communication
Multiplier: The multiplier value reads the referencer value of the point and then multiplies it by the current multiplier value.
Offset: The offset value is added to the raw point value. If the offset is positive, the value will be added to the referenced value. If the offset is negative, the value will be subtracted from the referenced value. See example below.
Update Interval: The update interval defines the frequency at which the point requests the value of its reference. To configure the update interval, select the amount of time and a time unit. The suggested minimum interval is 10 seconds.
Point Values
Units: Select the appropriate unit from the drop-down list.
Minimum Value: Enter a minimum value that the point can be at before it enters a fault state. The point value is capable of reporting a value below the minimum value, but any referenced value sent by the point will be capped at the minimum value. The system will not allow users to override a point at a value less than the minimum value. Third party systems are typically not affected by these parameters while performing overrides.
Maximum Value: Enter a maximum value that the point can be at before it enters a fault state. The point value is capable of reporting a value above the maximum value, but any referenced value sent by the point will be capped at the maximum value. The system will not allow users to override a point at a value greater than the maximum value. Third party systems are typically not affected by these parameters while performing overrides.
Change of Value Increment: The Change of Value Increment triggers the point to send the new current value to all subscriptions. When exceeded, and there is a change of value (COV) subscription for the point, the point sends the recipient of the subscription the new point value. For example, if the COV increment is set at 1.0 and the current value changes by 0.8, notification is not sent. However, if the current value changes by 1.1 since the last update, the point will send the new value to all subscriptions.
Alarm Conditions
Click Add Alarm Condition to specify a new alarm condition.
Low Limit:The low limit setting causes the point to enter a low limit condition when the value of the point is continuously less than the low limit value during the event time delay. The point returns to normal when the value continuously exceeds the low limit, plus the deadband value, during the event time delay.
High Limit: The high limit setting causes the point to enter a high limit condition when the value of the point is continuously greater than the high limit value during the event time delay. The point returns to normal when the value continuously drops below the high limit, minus the deadband value, during the event time delay.
Deadband: Deadband values are added or subtracted from the low limits or high limits to determine the return-to-normal value.
Event Time Delay: This is the amount of time that must pass when the point is out of range before the point will enter an alarm or fault condition. Time delay also applies when a point returns to a normal condition. See examples below.
Notifications and Reports: Set your notification preferences.
Click Apply to save your changes.

Details Tab

The Details tab displays the Property Names that can be read from the point and Current Value for the properties.
