Emerson MODBUS IP Manuel D’Utilisation

Emerson Network Power

®

 has introduced a new Liebert IntelliSlot

®

 card platform—the Liebert 

IntelliSlot Unity

™

 card.  This platform combines the Modbus 485, Modbus IP and BACnet IP outputs 

of existing cards into a common, unified platform. Liebert IS-UNITY

™

 allows selecting one of the 

available third-party protocols and the Liebert IS-UNITY-DP

™

 allows selection of two of the available 

protocols.
The Liebert IS-UNITY and LiebertIS-UNITY-DP cards are interchangeable with the IS-485L, 

IS-485X, IS-IPBML, IS-IPBMX, IS-WEBL and IS-WEBX cards for the protocols offered. The 

information output by the Unity cards is the same as the output of the IS-485L, IS-485X, IS-IPBML 

and IS-IPBMX cards. The cards offer Modbus IP/485 and BACnet IP.
The Liebert NX

™

 225-600kVA UPS is also supported with the Chloride ManageUPS Net Adapter +B 

communication card so the Modbus mapping supported with this configuration has been included.

This publication describes the Modbus and BACnet communications protocols available for 

communication with Emerson Network Power equipment. Included are the Liebert IntelliSlot 

Modbus 485, Modbus IP and the BACnet IP communications cards.

• The Modbus information includes implementation basics, supported types, frame format, function 

code support and similar subjects.

• The BACnet information includes the BACnet service listing, object types, device objects, analog 

objects, binary objects, multistate objects and BACnet engineering units.

Table 1 shows the type of Liebert IntelliSlot card required for selected Liebert products. Find the 

product first and the Reference Table, the three columns to the right of that are the cards supported 

for the product.
