Using definition:
_BYTE
represents 1 Byte (8 Bit)
_WORD
represents 2 Bytes (16 Bit)
ST_TIME_INT
represents 8 Byte (see below)
The structure ST_TIME_INT for the time representation is defined as follows:
_BYTE sekunden;
//seconds
_BYTE minuten;
//minutes
_BYTE stunden;
//hours
_BYTE tag; //days
_BYTE wochentag; //week day
_BYTE monat; //month
_WORD jahr; //year
The bytes are sent in the above byte order of the structure. The 175 bytes of the reserve are
not relevant and do not need to be interpreted. They are reserved for future use.
Additional definition
Invalid values are set to zero. Invalid values occur during the warm up phase of the system
after power up or if there is an error. This information can be taken from the status and the
transmitted error information.
6.1.2
Interface parameter
Configuration
9600 bit/s, 8 Data bit/n, 1 Stop bit, no parity
Interval for sending
Values are automatically transmitted every 15 seconds.
6.1.3
Data description
The transmitted data is defined as follows:
Name
Bytes
Description
dateTime
8
Current timestamp of the measurement instrument (military
time)
1. Byte:
seconds (decimal)
2. Byte:
minutes (decimal)
3. Byte:
hours (decimal)
4. Byte:
days (decimal)
5. Byte:
- not defined -
6. Byte:
month (decimal)
7-8 Byte (1 Word): year (decimal)
currChnl
2
Current measured channel / measurement point
Range: 1…8
currValues[10]
20
Current measured values from instrument (values, which are
also displayed in the instrument).
Values, which are transmitted with a decimal place information
(DPI), need to be divided by 10
DPI
to recover the decimal place
information
For example: CH
4
: a transmitted value of 4921 represents 49.21
Vol.%
1. Word:
CO
2
DPI: yes (2)
Unit: Vol.%
2. Word:
CH
4
DPI: yes (2)
Unit: Vol.%
3. Word:
H
2
S
DPI: no
Unit: ppm
4. Word:
O
2
DPI: yes (2)
Unit: Vol.%
