Requested function:
The status of any PLC variable registered to the Alarm Modem may be queried by SMS. Only one event will be used within the TiXML code, to reduce project size. Therefore the queried variable will be defined within the SMS itself.

SMS example: TIXI STATUS MARKER1
Password: TIXI
Event: STATUS
Parameter1: MARKER1

It would be possible to query MARKER2, MARKER3, TEMP5... too.

Necessary code:
At first the PLC variable will be defined within the external database using significant names, e.g.:
<Device _="1" Name="Device_0" Pollrate="1s">
<MARKER1 _="M" acc="R" def="" ind="1" />
<MARKER2 _="M" acc="R" def="" ind="2" />
...
</Device>

Next (besides the access protection with PW TIXI, missing here) the EventHandler for the SMS response and it's MessageJobTemplate (missing here) has to be created:
<STATUS>
<SendMail _="MessageJobTemplates/SENDSTATUS"/>
</STATUS>

The message text of the response links to the delivered variable. The variable name within the reference is taken from the received SMS by reference to ~/P1. The name of the variable will also be written into the SMS:

<Subject _="Status &#xae;~/P1;: &#xae;/Process/Bus1/Device_0/&#xae;~/P;1"/>

The response will look like this:
"STATUS MERKER1: 1"
