The measured values of the measuring channels A and B can be used for calculations by the calculation channels Y and Z.
Offset of the Parameter
For the calculation of the Modbus register address, an offset is added to the start address of the channel.
diagnostic value
diagnostic error bits 780 bit bit-coded variable in
the low-value byte of
the scaled lo word:
0000 0000 000H P0RR
with
H - hardware error
P - PIG detected
(set to 1 after
detection for 4...8 s)
R - reserved
no
Tab. 6.3: Offset of the Parameter
parameter offset explanation data Format
state 0 state of the measured value
0: not available
1: ok
2: failed
integer 16 bit
measured value, unscaled lo word 1 measured value with preset unit of measure-
ment in accordance with Tab. 6.2 floating point number
32 bit
measured value, unscaled hi word 2
ID of the unit of measurement 3 The unscaled measured value can be converted
to other units of measurement. For an overview
of the IDs see annex A.
If a wrong ID is written to the register or if the
transmitter was switched off, the last valid ID is
used.
If 0xFFFF is entered, the ID is increased by 1. If
the max. ID is reached, the ID is set to zero.
integer 16 bit
measured value, scaled lo word 4 measured value converted in accordance with
the ID of the unit of measurement floating point number
32 bit
measured value, scaled hi word 5
unit of measurement, ASCII part 1 6 unit of measurement in ASCII characters, e.g., l/
min ASCII
unit of measurement, ASCII part 2 7
unit of measurement, ASCII part 3 8
time since last update in s 9 integer indicating the time since the last update
of the measured value
The validity of the measured value based on this
value has to be assessed by the Modbus mas-
ter.
