8.2 Back-up controller (PROFIBUS)
Back-up operation: calculation of the control outputs is in the master. The con-
troller is used for process value measurement, correcting variable output and for
display.
With master or communication failure, control is taken over independently and
bumplessly by the controller.
8.3 Linearization
Linearization for inputs INP1 or INP3
Access to table “
Lin” is always with selection of sensor type S.TYP = 18:
special thermocouple in INP1 or INP3, or with selection of linearization S.Lin
1: special linearization.
Dependent of input type, the input signals are specified in µV or in Ohm
dependent of input type.
With up to 16 segment points, non-linear signals can be simulated or linearized.
Every segment point comprises an input (
In.1 … In.16) and an output (Ou.1
… Ou.16). These segment points are interconnected automatically by means of
straight lines. The straight line between the first two segments is extended
downwards and the straight line between the two largest segments is extended
upwards. I.e. a defined output value is also provided for each input value.
When switching an
In.x value to OFF, all other ones are switched off.
Condition for these configuration parameters is an ascending order.
In.1 < In.2 < ...< In.16 and Ou.1 < Ou.2 ...< Ou.16.
