ControlLogix 5000 Structured Text

I need to move values from a UDT to a new array.
Currently I am using:

HMI_BZ_PS[00] := XtrA_Bz1.PS;
HMI_BZ_PS[01] := XtrA_Bz2.PS;
HMI_BZ_PS[02] := XtrA_Bz3.PS;
HMI_BZ_PS[03] := XtrA_Bz4.PS;
HMI_BZ_PS[04] := XtrA_Bz5.PS;

But I have a lot of these to do. In the past I have been able to move large amounts of data using the following:

For i := 1 to 11 by 1

Do

OfflineDie_Zone_Heat_Cntrl.PS := HMI2CLx_REAL_OfflineDie_PS;

End_For;

I am wondering if there is a way to to add another variable to have it do the same function but to have it fill in number in the tag also:


HMI_BZ_PS := XtrA_Bz(b).PS;
HMI_BZ_PS := XtrA_Bz(b).PS;
HMI_BZ_PS := XtrA_Bz(b).PS;

It looks as though you cannot do what you want to do ...

Looks like everyone got the same homework.

The two ways I know to do what you are talking about one is:

A lot of work to redo your tag structure - use two arrays

The other I do not know if ST supports and that is concatenating strings, I have done similar to what you want in C# using this method, I assume its in VB also, but I do not know about ST - also this method might take more processing time it involves converting number to string, concatenating the string then making that string your variable name to equal the array element

Other than that its like Daba said in the linked post, big hammer method

ST will concat strings provided the strings you wish to join already reside in string tags, but the end result will never be a "tag" itself.
