The input value (included between minimum and max limit) is linearly
converted into the retransmitted value which is included between min
and max output value.
Rescaling is not executed if parameters and have the
same value.
9.2.2 Master Mode Remote process
To enable this function it is necessary to select on parameter
59 . In this mode the process value on ATR142 is a value
read via serial communication. The ID of the slave must be same as
value selected on parameter 57 and the word to read is
selected on parameter 60 . Two successive pollings will be
delayed for the time selected on parameter 57
The read
value might be rescaled according to the proportion described in the
following table:
Limits of read value Limits of rescaled value
