LIEBERT EQUIPMENT COMPATIBILITY

1.1

What’s New in This Manual
Emerson Network Power® has introduced a new Liebert IntelliSlot® card platform—the Liebert
IntelliSlot Unity™ card. This platform combines the Modbus RTU, Modbus TCP, BACnet MSTP and
BACnet IP outputs of existing cards into a common, unified platform. The Liebert IS-UNITY-DP card
allows selecting two of the available protocols.
The Liebert IS-UNITY-DP card is 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 Liebert Unity
card is the same as the output of the IS-485L, IS-485X, IS-IPBML and IS-IPBMX cards. The card
offers Modbus RTU/TCP and BACnet MSTP/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.

1.2

Connectivity to Liebert IntelliSlot Using Modbus RTU, Modbus TCP, BACnet
MSTP or BACnet IP
This document describes the Modbus and BACnet communications protocols available for
communication with Emerson Network Power equipment. Included are the Liebert IntelliSlot
Modbus RTU, Modbus TCP, BACnet MSTP 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.

1.2.1

Modbus Communications - Implementation Basics

2.0

MODBUS COMMUNICATIONS

2.1

Implementation Basics
Modbus protocol provides control and data acquisition, through query and response, between master
and slave devices. This protocol comprises the rules for communication, controlling the message
format between devices, how master and slave devices initiate communications, as well as unit
identification, message-handling and error-checking.
The Liebert IntelliSlot 485/IP card acts as a slave device on a network. This network can be a
multidrop configuration over EIA-485, where multiple slaves reside on a common wire or loop.

2.2

Transmission Format
The Liebert IntelliSlot 485/IP interface card supports Modbus Remote Terminal Unit (RTU)
transmission modes. See Table 2 below.

Modbus Packet Format
Each Modbus packet consists of these fields:
•
•
•
•

2.3.1

Device Address
Function Code
Data Field(s)
Error Check Field

Device Address
The address field immediately follows the beginning of the frame and consists of 8-bits (RTU). This bit
indicates the user-assigned address of the slave device that is to receive the message from the
attached master device.
Each slave must be assigned a unique address. Only the addressed slave will respond to a query that
contains its address.

Liebert® IntelliSlot® Modbus/BACnet

Modbus Communications - RTU Framing

2.3.2

Function Code
The function code field tells the addressed slaves what function to perform. Function codes are
designed to invoke a specific action by the slave device. The function code ranges from 1 to 127.
Liebert IntelliSlot Modbus server supports the following Modbus function codes.

Table 3

Supported Modbus function codes

Code

Function

Description

Read Coils

Read from 1 to 2000 contiguous status of coils managed by the server. Coils in the
response message are packed as one per bit of a byte, 1=On and 0=Off. If the requested
quantity of coils is not a multiple of 8, zeros are padded in the final byte.

Read Discrete Inputs

Read from 1 to 2000 contiguous input status managed by the server. Discrete inputs in
the response message are packed as one per bit of a byte, 1=On and 0=Off. If the
requested number of inputs is not a multiple of 8, zeros are padded in the final byte.

Read Holding Registers

Read the contents of contiguous block of 1 to 127 holding registers. Data are packed as
two bytes per register; the first byte contains the high order bits.

Read Input Registers

Read the contents of contiguous block of 1 to 127 Input registers. Data are packed as
two bytes per register; the first byte contains the high order bits.

Write Single Coil

Write a single output to either On (1) or Off (0) mapped in coil section.

Write Single Register

Write a value into a single holding register;

Write Multiple Coils

Force each coil in a sequence of coils to either On or Off.

Write Multiple Registers

Write values into a block of contiguous registers (1 to 120)

2.3.3

Data Fields
The data field length varies, depending on whether the message is a request or a response to a packet.
This field typically contains information required by the slave device to perform the command
specified or to the response to a data request from the master device.

2.3.4

Error Check Field
The Error Check Field consists of a 16-bit (2 byte) Cyclical Redundancy Check (CRC16). It allows the
receiving device to detect a packet that has been corrupted by transmission errors.

2.4

RTU Framing
The example below shows a typical query and response from a Liebert IntelliSlot interface card. The
master device initiates a query asking Slave Device, with address 2, for holding registers starting at
holding register 40051 (offset 50) and including next two registers (three total).
