Modbus RTU
The DXM700 manages two separate physical ports running the Modbus RTU protocol. The DXM700 is the Modbus
Master when operating the Modbus master RTU port. The DXM700 uses the master Modbus RTU bus to
communicate with locally connected Modbus devices or uses the Banner wireless radio to communicate with
remote Modbus devices.
The other Modbus RTU port is used by a host system to access the DXM700 as a slave device. The slave Modbus
RTU port allows access all the internal registers concurrently with the master RTU port. Set the slave Modbus ID
using the LCD menu: SYSTEM CONFIG > DXM Modbus ID.
By default, the Modbus RTU ports are active. Configure the port parameters using the DXM Configuration Tool.
Modbus TCP/IP
A host system acting as a Modbus client can access the DXM700 using the Modbus TCP/IP protocol over
Ethernet. Standard Modbus port 502 is used by the DXM700 for all Modbus TCP/IP requests.
All internal registers are available to the host system concurrently with Modbus RTU.
By default, Modbus TCP/IP is active. The DXM700 as a client is configured using Modbus TCP rules in the DXM
Configuration Tool.
EtherNet/IP
™
The Ethernet port is actively running EtherNet/IP. From the factory the DXM700 is configured to read and write
registers on DX80 wireless devices 1 through 16. Custom configurations can be set using the DXM Configuration
Tool.
By default, EtherNet/IP is active.
1.3 DXM Modbus Overview
The DXM700 uses internal 32-bit registers to store information. The processor's internal Local Registers serve as the main
global pool of registers and are used as the common data exchange mechanism. External Modbus device registers can be
read into the Local Registers or written from the local data registers.
The DXM700, as a Modbus master device or slave device, exchanges data using the Local Registers. Modbus over
Ethernet (Modbus/TCP) uses the Local Registers as the accessible register data.
Using Action, Read/Write, and Threshold Rules allows you to manipulate the processor's Local Registers. The ScriptBasic
programming capabilities extends the use of Local Registers with variables to create a flexible programming solution for
more complex applications.
The processor's Local Registers are divided into three different types: integer, floating point, and non-volatile. When using
Local Registers internally, the user can store 32-bit numbers. Using Local Registers with external Modbus devices follows
the Modbus standard of a 16-bit holding register. Local Registers are accessible as Modbus ID 199.
Accessing the I/O Base and the LCD follows the same communication as an external Modbus device. Each device has an
ID number to uniquely identify itself. The I/O base is Modbus ID 203 and the LCD is Modbus ID 201.
