Status information
Register Type Contents Length
0500 ro Module status 2 Byte
0501..0502 ro Channel status 4 Byte
<Module status>:
M16..M13 , M12..M9 = hex xy = 1. Byte
M8..M5 , M4..M1 = hex xy = 2. Byte
If the bit Mn in the module status is set it indicates that an error
has occurred in the sensor module, the following applies:
M1 = 1: EEPROM - Error
M2 = 1: Flash - Error
M3 = 1: ADC - Error
M4 = 1: Configuration - Error
M5 = 1: No memory card
M6 = 1: RTC - Error
M7...M16 Are currently not occupied
<Channel status>: K32..K29 , K28..K25 = hex xy = 1. Byte
K24..K21 , K20..K17 = hex xy = 2. Byte
K16..K13 , K12..K9 = hex xy = 3. Byte
K8..K5 , K4..K1 = hex xy = 4. Byte
If the bit Kn in the channel status is set it indicates that an error
has occurred in channel n.
