Object or Property Variable Type

In the EcoStruxure Building Operation database, you can create alarms or trend logs that are suitable for the variable type you have selected.

If you select objects or properties with different variable types, you can only mass create alarms or trend logs that have these variable types in common. For example, you want to create identical alarms for three analog variables and one multistate variable. When starting the New Object wizard, the EcoStruxure Building Operation software restricts you to create out of range alarms, out of reference alarms, or variable status alarms. This because of the multistate alarm is not suitable to analog variables.

Table: Suitable Alarms and Trend Logs for a Specific Variable Type

Type

Alarm

Trend Log

Analog variable

  • Out of range alarm

  • Out of reference range alarm

  • Variable status alarm

  • Interval trend log

  • Meter trend log

  • Change of value trend log

  • Variable triggered trend log

Multistate variable

  • Multistate alarm

  • Out of range alarm

  • Out of reference range alarm

  • Variable status alarm

  • Interval trend log

  • Meter trend log

  • Change of value trend log

  • Variable triggered trend log

Digital variable

  • Change of state alarm

  • Out of range alarm

  • Out of reference range alarm

  • Variable status alarm

  • Interval trend log

  • Meter trend log

  • Change of value trend log

  • Variable triggered trend log

Enumeration variable

  • Enumeration alarm

  • Multistate alarm

  • Out of range alarm

  • Out of reference range alarm

  • Variable status alarm

  • Interval trend log

  • Meter trend log

  • Change of value trend log

  • Variable triggered trend log

String variable

  • Matching text string alarm

  • Variable status alarm

A trend log can only monitor values, not text strings.

Note:

A trend log that monitors an enumeration records the enumeration value and not the enumeration definition.
