CatNet Systems CH-1 Help

The alarm editor allows editing of alarm conditions, messages and email recipients.

The status tab contains:

The current active/inactive status of the alarm.
The date and time of the last change of state of the alarm.
The last message generated by the alarm.
A refresh button to update the status on the screen.
A disable selection to completely disable the alarm.

This is where the alarm conditions are specified.

There are two modes for the conditions:

All conditions are true - The alarm will be active if every condition evaluates to true.
Any condition is true - The alarm will be active if any one of the conditions evaluates to true.

The condition(s) must be true for at least the number of minutes specified to be considered active. If any/all of the conditions become false for the same number of minutes, the alarm will change to inactive.

Up to six conditions may be entered. Click the "+" or "X" buttons to add or delete conditions. Each condition contains the following fields:

Point - A point must be dragged from the device tree and dropped here. The value of this point is what will be tested.
Comparison - This is the comparison that will be performed.
Comparison Value - This is what the point value will be compared with.

The comparison value can be any one of the following:

Numerical Value - Type any valid numerical value.
Another Point - Drag a point from the tree to compare with its current value. For digital and multi-state points, click the drop-down list to display the valid values.
Value Range - For the in/out of range comparisons, type the low value and the high value separated by a comma (eg: 50,100)
Value List - For the is/is not in list comparisons, type a list of values separated by commas (e.g. 1,2,3,5,85,1000).

Floating point values (e.g. 72.5) are valid, but will not always give the desired results. What displays on the screen as 72.5 may actually be 72.499854 because of the way computers round numbers. Testing a point value for equality with 72.5 will most likely always be false. Use "greater than", "less than" or a value range instead.

Messages Tab

Active Message

This is the message that is saved to the database and emailed when the alarm becomes active.

Clear Message

This is the optional message that is saved to the database and emailed when the alarm is cleared (becomes inactive).

Both messages may contain the following codes to embed information within the text:

@Vx - The value of the point (the point on the left-side).
@Cx - The comparison value (the point or value on the right side).

"x" in both codes is the condition number (1-6)

Example:
"Temperature is too high (@V1)." will be recorded as "Temperature is too high (77.4)".

Example:
"Temperature (@V1) is greater than setpoint (@C1)." will be recorded as "Temperature (76.3) is greater than setpoint (74.5)."

Notifications Tab

Email to Groups

Select the list of user groups that should receive this alarms messages. Every person in the group that has an email address in the user database will receive both active and clear messages.
