Disable Ethernet Port

Set to ON to power down the Ethernet interface. Disabling the
unused Ethernet port reduces power consumption.

The factory default position is OFF.

Disable LCD Display

Set to ON to disable the LCD. This DIP switch should be ON
when the LCD board is not connected.

The factory default position is OFF.

Ethernet

Before applying power to the DXM Controller, verify the Ethernet cable is connected.

The number of times the processor attempts to connect to the Ethernet network is configured in the DXM Configuration
Software (Settings

›

Network Ethernet Connection Acquisition). The default setting is two retries one minute after the device

boots up and another retry two minutes later.

The Ethernet connection supports the DXM Configuration Software, Modbus/TCP, and EtherNet/IP. ScriptBasic also has
access to Ethernet for custom programming. Use the software or LCD menu system to configure the characteristics of the
Ethernet connection, including the IP address. Any parameters not changeable from the menu system are configurable from
the configuration software.

Ethernet parameter changes entered through the LCD menu override the XML configuration parameters. To return to using
the network settings in the XML configuration file, remove the Ethernet parameters defined by the LCD menu using the
System Config

Reset menu.

USB

A micro USB port is available inside the DXM Controller.

The micro USB port can be used to configure the DXM, but a micro USB cable is not provided with the device.

Internal Local Registers (ID 199) for the DXM700, DXM1000,
and DXM1200

The main storage elements for the DXM Controller are its local registers, which can store 4-byte values that result from
register mapping, action rules, or ScriptBasic commands.

Local registers updated from Modbus transactions are restricted to a 16-bit data value to follow standard Modbus holding
register definition.

The local registers defined in action rules must all be within the same register group. For example, an action rule cannot have
inputs from an integer group with the result register defined as a floating point register. To move between integers and floats,
use the Register Copy Rule.

Local registers 1–850 and 5001–7000 are 32-bit integer registers
Local registers 851–900 and 7001–8000 are non-volatile 32-bit integer registers

Local registers 901-1000 are reserved for internal use

Local registers 1001–5000 are floating point format numbers, each address stores half of a floating point number; for

example, registers 1001 and 1002 store the first full 32-bit floating point number
Local registers 10000 and higher are read-only virtual registers; virtual registers collect various system-level data

Modbus registers for internal local registers (Modbus ID 199)
