Safety Guidelines ! ! ! Qualified Personnel Prescribed Usage ! Trademarks This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring to property damage only have no safety alert symbol. The notices shown below are graded according to the degree of danger. Danger indicates that death or severe personal injury will result if proper precautions are not taken. Warning indicates that death or severe personal injury may result if proper precautions are not taken. Caution with a safety alert symbol indicates that minor personal injury can result if proper precautions are not taken. Caution without a safety alert symbol indicates that property damage can result if proper precautions are not taken. Notice indicates that an unintended result or situation can occur if the corresponding notice is not taken into account. If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage. The device/system may only be set up and used in conjunction with this documentation. Commissioning and operation of a device/system may only be performed by qualified personnel. Within the context of the safety notices in this documentation qualified persons are defined as persons who are authorized to commission, ground and label devices, systems and circuits in accordance with established safety practices and standards.

Preface Purpose This manual is your guide to creating user programs in the Statement List programming language STL. The manual also includes a reference section that describes the syntax and functions of the language elements of STL. Basic Knowledge Required The manual is intended for S7 programmers, operators, and maintenance/service personnel. In order to understand this manual, general knowledge of automation technology is required. In addition to, computer literacy and the knowledge of other working equipment similar to the PC (e.g. programming devices) under the operating systems MS Windows 2000 Professional, XP Professional or MS Windows Server 2003 are required. Scope of the Manual This manual is valid for release 5.4 of the STEP 7 programming software package. Compliance with Standards STL corresponds to the "Instruction List" language defined in the International Electrotechnical Commission's standard IEC 1131-3, although there are substantial differences with regard to the operations. For further details, refer to the table of standards in the STEP 7 file NORM_TBL.WRI. Statement List (STL) for S7-300 and S7-400 Programming A5E00706960-01 iii
