This command is used to release the external control of the logic outputs: read or setup
Master (PC / SPS) sends
Slave (DAD 141.1) responds
Meaning
A1
A1:+00000
Output 1 based to gross value
A2
A2:+00002
Output 2 based to peak value
A1_1
OK
Output 1 set to base net value
A1
A1:+00001
Output 1 based to net value
Choose the base for the output ‘n’ like follows:

10.9.4. S
‘n’ Setpoint Value
[
Index 0x206C
]
This command is used to read or setup the 3 setpoints S0, S1 and S2. Permitted value range is +/- 999 999.
Master (PC / SPS) sends
Slave (DAD 141.1) responds
Meaning
S1
S1:+01500
Request: Setpoint S1 = 1500 d
S1 3000
OK
Setup: Setpoint S1 = 3000 d
Factory defaults
: S’0’ = 1000 d , S’1’ = 5000 d, S’2’ = 9999 d
10.9.5.
H’n’ Setpoint Hysteresis and Switching Action
[
Index 0x206A
]
The switching logic will be defined by the numeric value of hysteresis and the polarity.
The outputs can operate as “normally closed” or “normally open”, depending of the settings H’n’ and P’n’.
Examples of the swichting actions for a Setpoint value of 2 000kg
Polarity = 0 [OFF]:
Polarity = 1 [ON]:
