VAT 650 Series Installation, Operating, & Maintenance Instructions page 45

The «range of pressure and position values» is independent of the data type, equal for «signed integer» and «floating
point».
Note: The internal 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 CC-Link Master which will be adapted.
Note:
(upper scale value - lower scale value)
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 command i:24 add a string "False":
Example: s:24031234.56to7890
Example: s:24000to100.75
Example: s:2407-10.5to20.5
to 20.5 (=opened position)
6. Logic digital input close valve configuration
The «logic digital input close valve» can adjusted. See also chapter «Schematics».
The «logic digital input close valve» can be configured by 'Control View', 'Control Performance Analyzer', 'Universal Hyper
Terminal' or 'Service Box 2'.
The «set-command» is: «s:20000000a0».
The «get-command» is: «i:20». The answer returns the «operational settings mode»
