7.1.2 Sending SMS Text Messages to the ICX35-HWC

Using the Modbus Function Codes 6 and 16, a Modbus TCP/IP Client can send
SMS text message contents to the ICX35-HWC. In turn, the ICX35-HWC sends
the SMS text message to the phone number recipient(s).
Before triggering, you must first load the SMS text message contents, message
length, and phone number information. Below is a table of the Modbus addresses
used to send an SMS text message.
