User Manual For - CONTROLLER/DATA RECORDER MultiCon CMC-99/141
Fig. 7.119. Comparison of response of controller on change set point value with and without
fuzzy logic block use
–
Controller output
parameter block – this block contains the following parameters:
•
Offset
- value of this parameter causes offset of the controller output value,
•
Low output limit
– defines the low limit of the controller output signal value,
•
High output limit
– defines the high limit of the controller output signal value,
–
Initial conditions
parameter block contains the following options:
•
Init type
– contains following options:
◦
disabled
– during the start of the controller its output is in 0 state,
◦
value
– allows to set the controllers output state during its start depending
on
Low output limit
and
High output limit
parameters,
◦
from log. channel
– allows set up specified logical channel as a controllers
output state at the start-up moment,
•
Init source
– defines logical channel, which is a source of initial output,
•
Initial output
– parameter is visible for
Init type: Value
; defines the controllers
output state, where
0%
corresponds to
Low output
limit and
100%
corresponds
to
High output limit
,
Note!
After offsetting the output signal the output value is limited to the range set
in
Low output limit
and
High output limit
shows the block diagram of a control process of an object with the
Controller
implemented in the device. Set the setting of the selected Controller to be connected to the
Logical channel
operating in the
Controller
mode. In this
Logical channel
, select
the
Set point channel
and the
Feedback channel
, which store the data required to control
the object. Respectively, the
Set point channel
contains a destination value of the process,
