Sensor, analog outputs,
LED and buzzer status
bit[0]=0/1 – sensor
present/absent, RO
bit[1]=0/1 – analog outputs
deactivated/activated
bit[2]=0/1 – in case the
sensor is absent, turn
signaling off/on analog
output1
bit[3]=0/1 – in case the
sensor is absent, turn on
signaling with low
current/high current on
analog output1; if bit[2]=0 this
bit will be ignored
bit[4]=0/1 – in case of sensor
absent, turn signaling off/on
analog output2
bit[5]=0/1 – in case of sensor
absent, turn on signaling with
low current/high current on
analog output2; if bit[4]==0
this bit will be ignored
bit[6]=0/1 – current/voltage
