Inp absolute
The input behavior can be determined with this parameter.
OFF
The input quantity is processed with its sign.
ON
The input quantity is processed with a positive sign (absolute
value). It is possible to have a polarity change with the signs
of Mul gain or Div gain.
In order to write SOURCE LINK (1/6) parameter or DESTINATION LINK (1/6) parameter it is neces-
sary to add to the parameter number the offset “8192”
Eg.
RAMP REF 1 “44”
SOURCE LINK (1/2) = 44+8192 = 8236

The Links are executed with an approximate cycle time of 20 ms. They are not mainly intended
to be used for regulation but to access or connect parameters otherwise not accessible. The
use of Links according to the parameter chosen as a destination involves a CPU overhead
that can slow down the keypad/display operation. Check that the functionality corresponds
to the needs before plant-wide implementation.

The following parameters cannot be used as a destination of a Link:
- All parameters with only “R” access code
- All parameters with “Z” access code
- All parameters with “C” access code
