Instrument error
This register holds the overall error code for the instrument.
Normally this register should contain ‘00’ which means no error.
Instrument status
This register holds the overall status for the instrument
Bits set to 1 in this register have the following meaning:
Bit no Function Comment
0
Remote operation ‘1’ = On ‘0’ = Off
1 Program reset The bit is set each time the program starts, and
it indicates that volatile data is lost.
The bit is reset as Instrument status is read,
over serial communication (Modbus RTU) or
over Ethernet (Modbus TCP), for the first time
after reset/power-up. Note that the reply
contains the set bit if it was set.
Reading Instrument Status via Fieldbus interface
will not reset this bit. To reset this bit with
fieldbus interface a specific reset command
must be used.
Care must be taken if more than one interface is
used to communicate with the instrument and
the Program reset bit is to be used.
