Diagnostic Status [DWORD]
Coding of Diagnostic Status
ID
Description
0
Diagnostic values are indicated consecutively.
100
Bit-coded temperature status
0 = normal
Bit0 = 1 : Temperature threshold 1 has been exceeded
Bit1 = 1 : Temperature threshold 2 has been exceeded
Bit2 = 1 : Fault in temperature measurement
101
Measured temperature (10 000 Digit/ °C)
200
Bit-coded voltage status
0 = normal
Bit0 = 1 : L1+ (24 V) is faulty
Bit1 = 1 : L2+ (24 V) is faulty
201
Do not use it!
