The data table of outdoor measurements looks more comprehensive because of the

redundant sensor principle. Moreover are there further parameters (minimum, max-

imum, squared sum) which have to be recorded. An abstract of the outdoor data

table with its recording process for wind speed looks as follows:

DataTable(Table_Outdoor,True,-1)

DataInterval(0,60,Sec,10)

CardOut(1,-1000)

Average(2,WindSpd(1),FP2,False)

Minimum(2,WindSpd(1),FP2,False,False)

Maximum(2,WindSpd(1),FP2,False,False)

Totalize(1,WindSpd_SQ_1,IEEE4,False)

Totalize(1,WindSpd_SQ_2,IEEE4,False)

Sample(1,N,FP2)

EndTable

The totalize instruction is to add up the squared records within the time interval. In

association with the number of measured data N scaned by the Sample instruction,

you can have calculations concerning the standard deviation.

The Minimum and Maxiumum instruction contains an additional parameter "Time"

which determines, weather the time that the minimum or maximum value occurred

should be stored. In this case, it should not be stored.

Thus, wind speed is recorded once a minute. Data types are FP2 for fundamental

values (average, minimum, maximum) and IEEE4 for squared sum because of greater

recording results and consequently the necessity of greater memory usage. The

variable N is stored as number associated with the counter of measured data per

interval. Instructions for the other senors are equivalent to that and can be looked

up in the appendix section A on page 79.
