dear Alois
In some composite function blocks, sometimes we have a lot of variable values to store, and in other composite function blocks we need to access the values of these variables. Can we share data without the connection line between function blocks
best regards

hi,

IEC 61499 does not have something like global veriables which you would need for that feature. Have you had a look on structured data types or the adapter interface concept? This could improve the situation for you.
