Examples:
i:2400-0012345.12345to00123456.12345
i:2401-0001000.00000to00001000.00000
i:240200001000.00000to00001500.00000
Example «get-command» with Terminal: Get the range of Pressure Sensor 1:
The «range of pressure and position values» is independent of the data type, equal for «signed integer» and «floating
point».
Note:
The inte
rnal accuracy of valve is for all positions 100’000 steps and for all pressures 1’000’000 steps. If the range of
pressure and position values is rising, the accuracy of pressure and position will not rise. There is only the gain factor
between the VAT valve and the EtherCAT Master which will be adapted.
Note:
(upper scale value - lower scale value)
1
Note:
If at startup the scale values in the memory are out of range or the rule above is broken the default values are taken.
In this case the get comma
nd i:24 add a string “False”:
Example: s:24031234.56to7890
set the range of position from 1234.56 (= closed position) to 7890 (= opened position)
Example: s:24000to100.75
set the range of pressure from 0 (= 0 V) to 100.75 (= 10 V)
Example: s:2407-10.5to20.5
set the range of Position setpoint from -10.5 (=closed position)
to 20.5 (=opened position)
