The SMS phone book is where you define the list of GSM cell phone numbers that the PLC can use for SMS messaging. The phone book holds 6 numbers; however, you can dial more numbers by using an MI pointer. Each phone number can be up to 18 characters long. You can also add a description to identify who is being called. In addition, note that the number of the last received SMS is stored in SIs 188 to 192.
Open the Phone Book by clicking the button on the toolbar.
Click on an empty line in the Phone Book shown below, then type in the number.
Note that there are two formats for entering phone numbers shown below. If Limit to Authorized Phone Numbers is not selected, the PLC can send and receive SMS messages to/from any number in the Phone Book.
If Limit to Authorized Phone Numbers is selected:
Format 1: The PLC can receive messages from this number. This is because the number is in full GSM format, including the '+' in front of the country code.
Format 2: The PLC cannot receive messages from this number.
To edit the phone book, click in a number or description, then make your changes.
