Hello,

version PCS7 V7.0 SP1 / version SCL V5.3 SP2 ; code source SCL

I created a "tag" structure with attributes : S7_m_c and S7_xm_c, but I have 1 error in compilation of SCL, message is "attribute is not allowed for this tag"

When I put only  S7_xm_c, the error is " attribute  S7_xm_c is badly configured.

[code]  TAG { S7_m_c := 'true'; S7_xm_c := 'A,true ; B,true ; C,true ;'} : STRUCT

A : WORD; B : WORD ; C : WORD ; END_STRUCT;   [code]

----------------------------------------------------------------------------------------------------
Split from S7_xm_c attribute.

Hello DMasson

Are you creating a FB?

Which kind of variabele you are declaring: input, output, var, var_temp?

yes, I created a FB

I am declaring input variables

DMasson_ISIITECH

yes, I created a FB

I am declaring input variables

mmmm, sounds good.

I have copied your code and pasted it in a SCL code and it compiled without error in PCS7 V8.0.

The only think I can think of is that these S7_xm_c attribute is not released for your version. The use of structures is something of the last years.

I do not have a V7.0 system, so I cannot test my assumption.
