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 01.

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)
