The analog alarm extension contains attributes common to Metasys system objects.

The following table lists the attributes specific to the analog alarm extension. The list of attribute names are displayed in the Focus View of the alarm extension object. Click the attribute name in the table for a description of the attribute.

Notes:
  • In the Notes column, letters indicate the following: C - Configurable, D - Default Attribute for Display, N - Value Not Required, R - Affected by Extension’s Reliability, W - Writable. You can create attributes that are marked with a C in Metasys UI, and you can edit attributes that are marked with a W in Metasys UI.
  • In the MOD (Global Modify) column, attributes marked with an X can be mass edited from Global Search Results.
  • In the SCT (SCT Configuration Attribute) column, attributes marked with an X are viewable in the SCT Alarm Extension Focus Window.

Cooling Setpoint Reference

C,W

Null

 

When specified, indicates the Above Setpoint limit. You must define both the Cooling Setpoint Reference and Heating Setpoint Reference, or leave both blank. If the Cooling Setpoint Reference is defined, the High Warning Offset is added to the Cooling Setpoint Reference value to calculate the High Warning Limit.

Differential

C,W

0.00

Positive value

When the Cooling Setpoint and the Heating Setpoint are configured, the Differential specifies:

  • The deadband range for transitions to the Above and Below Setpoint states.
  • The deadband range for transitions from Above and Below Setpoint states to return to a Normal state. In this case, half of the value specified for the Differential is used. This allows the value to return to normal in cases where the control algorithm controls to a value close to the setpoint, but may not achieve or cross the setpoint.
