Task two: Create and send an SCI request from Digi Remote Manager
The second step in using the device_request module is to create an SCI request that Remote Manager
will forward to the device. For example, you can create in SCI request a the Remote Manager API
explorer:
1. In Remote Manager, click Documentation > API Explorer .
2. Select the device to use as the SCI target:
a. Click SCI Targets .
b. Click Add Targets .
c. Enter or select the device ID of the device.
d. Click Add .
e. Click OK .
3. Click Examples > SCI > Data Service > Send Request .
Code similar to the following will be displayed in the HTTP message body text box:
<sci_request version="1.0">
<data_service>
<targets>
<device id="00000000-00000000-0000FFFF-A83CF6A3"/>
</targets>
<requests>
<device_request target_name="myTarget">
my payload string
</device_request>
</requests>
</data_service>
</sci_request>
Note The value of the target_name parameter in the device_request element must
correspond to the target parameter of the device_request.register function in the Python
script. In this example, the two are the same.
4. Click Send .
Once that the request has been sent to the device, the handler on the device is executed.
n

>>> received request
my payload string
for target myTarget
>>>
n In Remote Manager, you will receive a response similar to the following:
<sci_reply version="1.0">
<data_service>
