5.5.1.4. Averaging time
Various averaging time of the measured value can be defined
in transducer PCE-P30U. Averaging time of measured value can be
set within 0.075...0,2...20 s range – the moving window averaging
function has been used. The minimal time below 0,2 s can only be used
for input types:
Voltage -10..10V
,
Voltage -24..24V
,
Current -20..20mA
.
5.5.1.5. Maximum and minimum values of measured signals
The PCE-P30U transducer has been fitted with the function
of storing minimum and maximum value with the time and date
of occurrence. Minimum and maximum value are stored after a power
supply loss, they can be read and reset using transducer registers
via Modbus protocol (RS-485, TCP/IP – see table 37, WWW server,
they can also be displayed on the display using the following keys:
- the maximum value,
- the minimum value.
Erasing the minimum and maximum value is possible via keypad after
pressing the combination of
and
.
5.5.1.6. Mathematical operations on measured values
The transducer enables the performance of additional mathematical
operations on the measured value. The following mathematical opera-
tions have been implemented in the transducer:
•
mathematical functions,
•
21-point individual characteristic,
•
display range limit (main input only).
The way in which the mathematical operation influences the measured
value is shown at fig. 12. Switching on and selection of the mathematical
operation is possible via the keypad, Modbus protocol (RS-485, TCP/IP)
and WWW server.
