The ASCII character of the end identifier
Left Byte: 1. end character
Right Byte: 2. end character
is used as the 2. end character 0h. In this way only one end character is evaluated.
ZVZ
Character delay time in 50ms units.
FEHL
This byte has a value of 0, if functioning correctly. In the case of a malfunction an
error code is entered. The error is acknowledged immediately, i.e. the byte is reset
at 0 once the cause of the error has been eliminated.
An overview of the possible error codes can be found in chapter 4.1.5.3.
