Fieldbus Manual

5-4

Note 1: This value is in integer format if parameter

Data Format

is set to

Integer

or in float

format if parameter

Data Format

is set to

Floating Point

.

Note 2: The number of decimals used in these values depends on the resolution setting for the
scale. Actual number of decimals is shown in byte 88.

Note 3: The number of decimals used in flow rate depends on the resolution setting for the flow
rate. Actual number of decimals is shown in byte 89.

Note 4: The input signal always has 5 decimals. Unit is mV/V.

Note 5: Low part has 3 decimals.

Note 6: Analog output value always with 3 decimals.

Note 7: Analog input value always with 3 decimals.

Note 8: The value is in integer format, i.e. it does not have any decimals.

Note 9: These bytes are not used in the standard version of the G5 software. The content is
always 0.

Input data mapping is shown in the table on previous page. Input data is 106 bytes as
described in the table. Data direction is from G5 Instrument to network (PLC).

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.
