Rice Lake PR5220 Ethernet Transmitter - Manual (Page 137)

PR 5220 Instrument Manual Fieldbus Interface
Sartorius EN-137
Output Area
Data transmission from the PR 5220 to the master is via the output area.
The weight or data information requested by the master is transmitted to the master by PR 5220.
PR 5220 has write access, the master has read access.

Variable Function
Read_Value The weight value is transmitted as a binary 32-bit value 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 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 Max. capacity, but is still within Max +
permissible overload (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 )
