Serial Communication – EFB
Supported Features
In the N2 Fieldbus protocol the ACH550 drive appears as a “virtual object”.
A virtual object is made up of:
•
Analog Inputs
•
Binary Inputs
•
Analog Outputs
•
Binary Outputs
•
Internal values for Floating point, Integer, and Byte values.
The ACH550 drive does not support N2 Fieldbus communication “internal values”.
All of the Analog and Binary I/O objects are listed below, starting with "N2 Analog
Input Objects" on page 173.
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
