8.2.1 Basic Approach to Configuration
When programming an application in the DXM, first plan the overall data structure of the Local Registers. The Local
Registers are the main storage elements in the DXM. Everything goes into or out of the Local Registers.
1. In the DXM Configuration Software, name the Local Registers to provide the beginning structure of the application.
2. Configure the read/write rules to move the data. The Read/Write rules are simple rules that move data between
devices (Nodes, Modbus slaves, sensors, etc) and the Local Registers.
3. Most applications require the ability to manipulate the Local Register data, not just move data around. Use the
Action
rules
to make decisions or transform the data after the data is in the Local Registers. Action rules can apply many
different functions to the Local Register data, including conditional statements, math operations, copy operations, or
trending.
4. To perform scheduled events in Local Registers, go to the
Scheduler
screen in the DXM Configuration Software.
These rules provide the ability to create register events by days of the week. The scheduler can also create events
based on sunrise or sunset.
8.2.2 Troubleshooting a Configuration
View Local Registers using the
Local Registers
>
Local Registers in Use
screen of the DXM Configuration Software.
When a configuration is running on the DXM, viewing the Local Registers can help you to understand the application's
operation. This utility can also access data from remote devices.
To configure the Local Register data to display on the LCD menu, go to the
Local Registers
screen, set the
LCD
permissions
to read or read/write.
8.2.3 Saving and Loading Configuration Files
The DXM Configuration Software saves its configuration information in a XML file. Use the
File
menu to Save or Load
configuration files.
Save the configuration file before attempting to upload the configuration to the DXM. The DXM Configuration Software
uploads the configuration file saved on the PC to the DXM; it will not send the configuration loaded in the tool.
8.2.4 Uploading or Downloading Configuration Files
The DXM requires a XML configuration file to become operational. To upload or download configuration files, connect a
computer to the DXM using the USB port or Ethernet port. Then use the
Upload Configuration to Device
or
Download
Configuration from Device
under the
Device
menu.
8.3 Scheduler
Use the
Scheduler
screens to create a calendar schedule for local register changes, including defining the days of the week,
start time, stop time, and register values.
Schedules are stored in the XML configuration file, which is loaded to the DXM. Reboot the DXM to activate a new schedule.
If power is cycled to the DXM in the middle of a schedule, the DXM looks at all events scheduled that day and processes the
last event before the current time.
For screens that contain tables with rows, click on any row to select it. Then click
Clone
or
Delete
to copy/paste or remove
that row.
