In the RS422 menu item, you define which results of the calculation blocks will be output
at the interface.
The specification of minimum and maximum measured values or calculation result is still
required as well as output value.
The measured value (calculation result) to be output is automatically scaled for the 16-
bit, i.e. 65536 values, output in the CSP2008.
The digital output value is produced according to the formula:
Digital value = * 65535
Measured value - Min. output value
Max. output value - Min. output value
Example: Min. Output Value (Measured Value) = -50,
Max. Output Value (Measured Value) = +50, Measured Value = -25;
Digital value = * 65535 = 16384
-25 - (-50)
50 - (-50)
Values outside the specified limits are output as errors.
