Content	Creating STL Source Files 13.3 Structure of Blocks in STL Source Files Programming with STEP 7 286 Manual, 05/2010, A5E02789666-01 13.3 Structure of Blocks in STL Source Files The blocks in STL source files are structured using keywords. Depending on the type of block, there are differences in the structure of: • Logic blocks • Data blocks • User-defined data types (UDT) 13.3.1 Structure of Logic Blocks in STL Source Files A logic block is made up of the following sections, each of which is identified by the corresponding keyword: • Block start, • identified by keyword and block number or block name, for example - ORGANIZATION_BLOCK OB1 for an organization block, - FUNCTION_BLOCK FB6 for a function block, or - FUNCTION FC1 : INT for a function. With functions the function type is also specified. This can be an elementary or complex data type (with the exception of ARRAY and STRUCT) and defines the data type of the return value (RET_VAL). If no value is to be returned, the keyword VOID is given. • Optional block title introduced by the keyword TITLE (max. length of title: 64 characters) • Additional comments, beginning with a double slash // at the start of the line • Block properties (optional) • Variable declaration section • Code section, beginning with BEGIN. The code section consists of one or more networks that are identified by NETWORK. You cannot enter a network number. • Optional network for each network used, introduced by the keyword TITLE = (max. length of title: 64 characters) • Additional comments for each network, beginning with a double slash // at the start of the line • Block end, identified by END_ORGANIZATION_BLOCK, END_FUNCTION_BLOCK, or END_FUNCTION • A blank must be placed between the block type and the block number. The symbolic block name can be identified by quotation marks to ensure that the symbolic names of local variables and names in the symbol table remain unique.
