G5 Weighing Instrument
5-5
Instrument state
This register contains the state of the G5 instrument.
Code Description
00 ‘Starting up’ state.
The instrument is starting up after a reset or power on.
01 ‘Wait for start’ state.
The instrument is waiting for a start command to go in process.
02 ‘Warming up state’
The parameter ‘Warm up time’ is set to a value other than zero, and
the instrument is waiting for the warming up time to pass.
03 ‘Normal’ state.
There are no parameter errors in the system.
Note: Weight errors still indicate normal state.
04 ‘Error’ state.
An error has been detected during startup of the instrument.
05 ‘Fatal error’ state.
An error has been detected during startup of the instrument.
It’s not possible to enter any other state from here.
06 ‘Power fail’ state.
A power fail has been detected and the instrument will respond to
communication for a short moment until the power supply reserves are empty
(this is normally just a few ms). Weight values should be regarded as invalid.
Command acknowledge
This byte returns the value of the command if it could be executed. If there was an
error executing the command the value 240 (hex F0) will be returned in this byte. This
byte should be used to verify that a command has been executed.
Note that a new command is detected when the content of the command register is
changed. If the same command shall be issued again, the command byte must first be
set to 0 and this should be verified by reading command acknowledge. Then the
desired command may be issued.
Command error
This byte holds the error code when a command has been sent to the instrument.
Normally this register should contain ‘00’ which means no error. Error codes 0 to 255
are valid in this register.
Level status 1 - 4
Bits in this byte have the following meaning:
Bit no Function Comment
0 Above level 1 The weight is above Level 1.
1 Above level 2 The weight is above Level 2.
2 Above level 3 The weight is above Level 3.
3 Above level 4 The weight is above Level 4.
