it is simply declared as array as shown below:

Public T107_C(2)

Public TRHData(2)

Alias TRHData(1)=Temp_C

Alias TRHData(2)=Humid_C

This creates in memory four variables T107_C(1), T107_C(2), Temp_C and Hu-

mid_C. Thus, the amount of required code reduces to a minimum. Furthermore,

this example demonstrates the use of aliases which is equivalent to the assignment

of stored ASCII data within the TRHData-Array to the variables Temp_C and

Humid_C. The procedure of declaration is repeated to name every sensor and cal-

culating process with its own variable for further output and storage.

Data Types and Operational Detail

Variables and stored data can be conﬁgured with various data types to optimize

program execution and memory usage. Table 4.1 gives an outline of the used data

types.

Table 4.1: Details of used Data Types

[Manual - CR1000 Measurement & Control System, 1/08]

The declaration of variables via PUBLIC or DIM statement allows an optional type

descriptor AS that speciﬁes the data type. The default data type, without a de-

scription, is IEEE4 ﬂoating point (FLOAT).
