7.2.2 Output Area


Data transmission from the PR 5410 to the master is via the output area.
The weight or data information requested by the master is transmitted to the master by PR 5410.
The PR 5410 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.

Dimmed

Above Max. capacity or below zero

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

)

AdcError

A/D conversion error. (Details are given in register 1,

Read_Value_Select = 1

)
