When writing to the 32-bit area of the Web-IO (starting at
address 0x5000) two 16-bit registers per 32-bit value beginning
with the highest byte of the 32-bit value must be written.
The Web-IO replies with a data packet having the following
structure:
1. Byte
16 Bit / Word
High Byte

Registers
Start Address
Specifies at which address to begin writing the 16-bit registers.
Quantity of Outputs
Here the number of written 16-bit registers is sent.
10.7 Socket-API
You can retrieve measurement data directly from the device via
a socket access.
In the simplest case, send the „GET / Single“ command to the
device to return all measured data from the device.
Configure the settings for HTTP and UDP access here.
