Output Area
Data transmission from the PR 5230 to the master is via the output area.
The weight or data information requested by the master is transmitted to the master by PR 5230.
The PR 5230 has write access, the master has read access.

Variable
Function
Read_Value
The weight value is transmitted as a binary 32-bit number with plus or minus
sign.
Data type: DINT
Read_Value_Selected
Acknowledgement of the transmitted value.
Write_Active
The function selected with Write_Value_Select is executed once.
This bit is deleted, when Write_Value_Select is set to 0.
Power_Fail
Is set when switching on the instrument.
Is reset by ResPower with transition from 01.
Cmd_Busy
The instrument is busy executing a command (e.g. the instrument has received a
taring command and waits for stability.
Cmd_Error
The instrument has interrupted the execution of a command (e.g. Standstill could
not be reached within the defined standstill time). The error number can be read
at LastError. It is set only, if an action is executed.
Tare_Active
The instrument was tared.
Cal_Active
The instrument is / was configured. When this bit is 1, the scale parameters
(Expo/Unit/Step) must be read again. Set after power On and reset after reading
the max. capacity.
Test_Active
The instrument executes the ADC test. The read weight value is not the gross
value, but the test value.
Out
Below zero or above Max (FSD)
Standstill
The instrument is stable.
InsideZSR
The weight value is within the zero setting range.
CenterZero
The weight value is within center zero ( 0 +/- 0.25 d )
BelowZero
The weight value is negative (gross< -0.25d)
Overload
The weight value has exceeded the measuring range; no valid weight data is
specified (gross>max. capacity+overload)
AboveMax
The weight value has exceeded the Max. capacity, but is still within
Max + permissible overload (gross <= max. capacity+overload)
AduError
A/D conversion error. (Details are given in register 1, Read_Value_Select = 1)
