Description
DATA TYPE
Set 16 49 1 3 1 X
Get 14 49 1 3 1
X: 195 signed integer
202 floating point
This command defines the data type for PRESSURE, SENSOR READING, OFFSET and
POSITION.
GAIN PRESSURE
Set 16 49 1 14 4 X
Get 14 49 1 14 4
X: gain, max. value is 3.2767, data type is floating point
This command selects the gain for PRESSURE and allows for scaling.
Default value is 1 (3Fh 80h 00h 00h).
e.g.:
Gain = 0.1
pressure value range results in 0-1’000
Gain = 1 pressure value range results in 0-10’000
Gain = 3.2767 pressure value range results in 0-32’767
GAIN POSITION
Set 16 49 3 14 4 X
Get 14 49 3 14 4
X: gain, max. value is 3.2767, data type is floating point
This command selects the gain for POSITION and allows for scaling.
Default value is 1 (3Fh 80h 00h 00h, “high byte first” notation).
e.g.:
Gain = 0.1
position value range results in 0-1’000 (3Dh CCh CCh CCh)
Gain = 1 position value range results in 0-10’000 (3Fh 80h 00h 00h)
Gain = 3.2767 position value range results in 0-32’767 (40h 51h B5h 73h)
POLL OUTPUT
Set 16 5 2 100 1 X
Get 14 5 2 100 1
X: output assembly object number (7, 8, 102)
This command configures resp. reads the output assembly for poll connection.
POLL INPUT
Set 16 5 2 101 1 X
Get 14 5 2 101 1
X: input assembly object number (3, 4, 5, 13, 14, 100, 101)
This command configures resp. reads the input assembly for polling.
BIT STROBE INPUT Not implemented
Unless otherwise specified all values in the table above are in decimal notification. Hexadecimal values
are indicated by the letter ‘h‘ (e.g. 31h)
