Coils - Read/Write parameters
Address Type Coil description
1 b Logging status: 0=active, 1=inactive
2 b Logging mode: 0=non cyclic, 1=cyclic
3 b Set 1 to delete the device logging memory. Bit zeroing is automatic.
4 b Buzzer activation in case of measurement alarm: 0=no, 1=yes
9 b
Protection of configuration with password: 0=no, 1=yes
Changing the parameter requires the Administrator password (see Holding
Register 10036).
71 b Type of calibration in use: 0=factory, 1=user
72 b
Set 1 to perform the differential pressure calibration at zero. Bit zeroing
is automatic.
73 b Differential pressure self-calibration status: 0=off, 1=on
