Data Arrays

10/00 AWB27-1301-GB

Working with data arrays

The next section describes how to read or write data arrays
using the example of the send and receive data arrays of a
primary station.

Ensure that all the array indices are within the limits when
accessing data arrays. If the array index limits are exceeded,
the controller will STOP and the NOT READY LED will light
up.

The data arrays were defined as follows in the variable
declaration for the function block:

Writing data array elements

To save the constant “5” in the array element station “3”,
subaddress “0”, offset address “10” of the send data array,
proceed as follows:

VAR_INPUT

tra_dat: ARRAY[1..5, 0..0, 0..31] OF BYTE;

(*Send data array (station number,
subaddresses, offset addresses)*)

END_VAR

VAR_OUTPUT

rec_dat: ARRAY[1..5, 0..0, 0..31] OF BYTE;

(*Receive data array (station number,
subaddresses, offset addresses)*)

END_VAR

LD 5

ST Instance_name.tra_dat [3,0,10]

END_PROGRAM
