5.3.5 Channel status
5.3.6 Measuring units: 1 byte
When the bit with the biggest weight (0x80) is activated, it indicates sensor alarm.
Table 5-1Channel status
Bit Value Description
0 0x1 Limit 1 active
1 0x2 Limit 2 active
2 0x4 Alarm active
3 0x8 Measurement error (for example, measurement out of range)
4 0x10
Temperature error (measurement out of range or probe not
connected)
5 0x20
Cleaning relay active (while cleaning the measurements are
blocked)
6 0x40
Intermittent bit to detect active communication of the
instrument (must change at least 1 time each 2 seconds)
7 0x80
Channel bit active. Indicates that the measuring board is
connected and the channel is active. Calibrating or
programming the channel, this bit is 0
