DXM1200 Automation Protocols
The DXM Controller supports the following automation protocols.
Modbus® RTU
The DXM Controller manages separate physical ports running
the Modbus RTU protocol. The DXM Controller is the Modbus
client when operating the Modbus client RTU port. The
DXM
Controller uses the client Modbus RTU bus to communicate
with locally connected Modbus devices or uses the Banner
wireless radio to communicate with remote Modbus devices.
Modbus TCP/IP
A host system acting as a Modbus client can access the DXM
Controller using the Modbus TCP/IP protocol over Ethernet.
Standard Modbus port 502 is used by the DXM Controller for
all Modbus TCP/IP requests.
All internal registers are available to the host system
concurrently with Modbus RTU.
By default, Modbus TCP/IP client is active. If you are using the
DXM as a Modbus TCP client, configure the DXM Controller
using Modbus TCP rules in the DXM Configuration Software.
EtherNet/IP™
The Ethernet port is actively running EtherNet/IP. From the
factory, the DXM Controller is configured to read and write
registers on DX80 wireless devices 1 through 16. Custom
individual local register configurations can be set with the
Protocol Conversion field in the DXM Configuration Software.
By default, EtherNet/IP is active.
EtherNet/IP registers are limited to 228 registers set as E/IP
Originator to DXM and 228 registers set as DXM to Originator.
PROFINET® (DXM1200-X2 only)
By default, PROFINET is disabled on the DXM1200-X2.
To configure the DXM1200-X2 for PROFINET
communications, PROFINET must be enabled using the DXM
Configuration Software. The DXM1200-X2 uses fixed Slot
sizes and locations in the Local Registers for the Input and
Output values. Module sizes supported are 64, 128, 256, and
512 bytes which range from 32 to up to 256 Local Registers in
the DXM1200-X2.

DXM1200 Modbus Overview
The DXM Controller 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 DXM Controller, as a Modbus client device, exchanges data using the Local Registers. Modbus over Ethernet (Modbus/
TCP) uses the Local Registers as the accessible register data.
