Note
Address register AR2 is used in the block. However, this register is also used for multi-
instance DBs. For this reason, the relevant FB must not be declared as a multiinstance
DB.

//To deactivate multi-instance DB with STEP 7 Version
2 and higher
//Observe predetermined order
//10 bytes per ANY
//Transfer pointer value to VAR_TEM
//ANYPAR is data type ANY
