Send Text Alerts and Commands from the DXM

A DXM Controller with a cellular modem can send text messages on defined conditions and can receive text messages to trigger actions.

This short example uses the DXM Configuration Tool to create text alerting messages and SMS commanding.

For more DXM Controller information, refer to the appropriate instruction manual.

• DXM Configuration Tool Instruction Manual (p/n 158447)
• DXM100-Bx Wireless Controller Instruction Manual (p/n 190037)

A complete XML configuration file is available for this technical note. The XML configuration file uses a dummy phone number. Use the DXM Configuration Tool to replace the dummy phone number with your phone number.

Hardware requirements:

• A DXM Controller model with a cellular modem installed (the cell modem must have a wireless plan and be provisioned on the cellular network)
• DXM Configuration Tool software downloaded from www. bannerengineering.com

This example configuration:

1. Reads four discrete inputs from the I/O board of the DXM Controller.
2. Writes the values into Local Registers 1 through 4.
3. Defines a math rule to logically 'OR' the input values.
4. Uses a threshold rule to define when to send a text message.
