Liebert Equipment Compatibility - What’s New in This Manual

1.0 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 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.

1.2 Connectivity 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.
• 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 How to Use This Manual

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 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.

2.3 Modbus Packet Format

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

2.3.1 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.

IntelliSlot® Modbus/BACnet IP
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
Table 3 Supported Modbus function codes
Code Function Description
01 Read Coils
02 Read Discrete Inputs
03 Read Holding Registers
04 Read Input Registers
05 Write Single Coil Write a single output to either On (1) or Off (0) mapped in coil section.
06 Write Single Register Write a value into a single holding register;
15 Write Multiple Coils Force each coil in a sequence of coils to either On or Off.
16 Write Multiple Registers Write 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.

2.3.3 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).

Slave Device, with address 2, responds to Function Code 3 with 6 bytes of hexadecimal data and ends with CRC16 checksum.
Register values: 40051 = 158 (hex) = 344 (decimal)
40052 = FA (hex) = 250 (decimal) 40053 = 54 (hex) = 84 (decimal)
