Ts Sampling time,
duration of a time slice
Fixed
500 ms
TI Integral time
Parameter TI, if you set this
parameter to 99:59 min, then you
switch off the I part of the controller.
00:01 min to 99.59 min
en
Loop error at the time n;
generally applies: e = SP –
PV
Refer to SP and PV
"
SP
The parameter SP is the set-value
assignment w. For this parameter you
can use the analog output of a
different special function.
-10,000 to +20,000
PV
PV is the process value x and is
calculated as follows:
PV = (analog value on input * gain) +
offset.
You can connect the input for
example by means of an analog input
with a PT100 sensor.
"
The gain parameter has an effect on
PV
0.0 to 10.0
The offset parameter has an effect on
PV
-10,000 to +20,000
PV is restricted by the parameters
Min. and Max.
In each case: -10,000 to +20,000
The Dir parameter gives the action
direction of the controller.
Positive means: If set value > process
value then the process value is
increased; if set value < process
value then the process value is
reduced.
Negative means: If set value >
process value then the process value
is reduced; if set value < process
value then the process value is
increased.
e.g. heat regulation: if the set value is
greater than the process value (room
is too cold), the manipulated variable
increases the process value.

Only when there is a low to high trigger at Trg pin, the Memory Write block will be activated
and the pre-configured record action will be performed, at the same time the output will
switch on if the record action had been done successfully.
