Liebert Equipment Compatibility - What’s New in This Manual
1.0LIEBERT EQUIPMENT COMPATIBILITY
1.1What’s New in This Manual
Emerson Network Power® has introduced a new Liebert IntelliSlot® card platform—the Liebert
IntelliSlot Unity
of existing cards into a common, unified platform. Liebert IS-UNITY
available third-party protocols and the Liebert IS-UNITY-DP
™
card. This platform combines the Modbus 485, Modbus IP and BACnet IP outputs
™
™
allows selecting one of the
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.
1.2Connectivity to Liebert IntelliSlot Using Modbus 485, Modbus IP or BACnet IP
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.

Modbus Communications - Implementation Basics
2.0MODBUS COMMUNICATIONS
2.1Implementation 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
multidrop configuration over EIA-485, where multiple slaves reside on a common wire or loop.
2.2Transmission Format
The Liebert IntelliSlot 485/IP interface card supports Modbus Remote Terminal Unit (RTU)
transmission modes. See Table 2 below.

2.3Modbus Packet Format
Each Modbus packet consists of these fields:
• Device Address
• Function Code
• Data Field(s)
• Error Check Field
2.3.1Device 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.

IntelliSlot® Modbus/BACnet IP
Modbus Communications - RTU Framing
2.3.2Function 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
Table 3Supported Modbus function codes
CodeFunctionDescription
01Read Coils
02Read Discrete Inputs
03Read Holding Registers
04Read Input Registers
05Write Single CoilWrite a single output to either On (1) or Off (0) mapped in coil section.
06Write Single RegisterWrite a value into a single holding register;
15Write Multiple CoilsForce each coil in a sequence of coils to either On or Off.
16Write Multiple RegistersWrite values into a block of contiguous registers (1 to 120)
®
Modbus server supports the following Modbus function codes.
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 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 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 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.
2.3.3Data 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.
2.3.4Error 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.
2.4RTU 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).

1. Timer mode: 0 = no, 1 = yes
2. Type of DT Room-Glycol: 0 = no, 1 = contact, 2 = value
5. When VFD is set to manual mode (coil 22), the host can control the VFD by the value of register 40019. The Manual VSD
Timer will start to count down. Once it reaches 0, the VFD control mode will switch to auto. The host will need to periodically
reset this timer in order to maintain the manual mode. Consult factory for BMS timer information.
