Example: Send data permanently
NOTICE
When the device is starting up and during a restart, no data telegrams or responses are sent by the device for a
period of up to 30 seconds. The blank spaces (hexadecimal: 20) must be added to the calculation of the telegram
length when both sending and receiving telegrams. With CoLa Binary, framing has a length of 9 bytes (4 bytes STX,
4 bytes; telegram length without framing, 1 byte XOR checksum).
