Parameter:
AnalogInput_1 ... _4
Declaration:
INPUT
Data type:
WORD
Range of
values:
See address range
Default:
0 (W#16#0)
Address
range:
I/O words
PIW0 ... PIWn
Memory words
MW0 ... MWn
Data words
LW0 ... LWn
DBm.DBW0 ... n
Explanation:
Analog input word
For each analog value to be transmitted in the data frame, you can specify
from wh
ere the FB will take the analog information. I/O words from analog
input modules, data words from a data block and memory words can be mixed
as required.
If you do not require parameters, simply leave them open. The value 0 is
transferred for these analog inputs in the data frame.
Parameter:
SamplingPeriod
Declaration:
INPUT
Data type:
INT
Range of
values:
0 ... 32767 [ms]
Default:
500
Explanation:
Acquisition interval for analog inputs in milliseconds
The acquisition interval is required for the fol
lowing parameters:
•
Threshold formation according to the integration principle (Threshold
Integration)
•
Smoothing of the analog input value (Smoothing Factor)
•
Mean value generation
The value must be selected high enough so that it is certain that a new value
was acquired within the encryption time of the analog input. The interval to be
specified has to be at least as long as the encoding time of the analog input
module being used at the selected resolution (8 ... 15 bits).
The value must also be selected gen
erously so that analog values are ac-
quired even with the highest resolution and with analog modules with the
highest number of inputs.
If mean values are calculated, SamplingPeriod should not be less than 500
ms. If mean values are calculated over very lon
g periods, the time must be
increased as follows:
•
Mean value calculation period 12 h: SamplingPeriod = 1000 [ms]
•
Mean value calculation period 24 h: SamplingPeriod = 2000 [ms]
Specifying a "SamplingPeriod" that is too short may lead to an overflow of the
i
nternal accumulation counter. The maximum value of 2 147 483 647 of a
double integer must not be exceeded. When an overflow is detected, the inv
a-
lid mean value of 8000
H
is transferred for the current mean value calculation
period.
