Analog input – The analog input objects support the following features:
• Analog Input actual value in engineering units
• Low Alarm limit
• Low Warning limit
• High Warning limit
•High Alarm limit
• Differential value for the hysteresis of the Alarms and Warnings
• Change of State (COS) enabled
• Alarm Enabled
• Warning Enabled
• Override value is received, but there is no action taken.
Binary input – The binary input objects support the following features:
• Binary Input actual value
• Normal / Alarm state specification
• Alarm Enabled
• Change of State (COS) enabled
• Override value is received, but there is no action taken.
Analog output – The analog output objects support the following features:
• Analog Output value in engineering units
• Override value is used to change the Analog Output value. It is not possible to
return to the previous value by removing the override. The override feature is
used only to change the value.
Binary output – The binary output objects support the following features:
• Binary Output value
• Override value is used to change the Binary Output value. It is not possible to
return to the previous value by removing the override. The override feature is
used only to change the value.
