STEP 7 Lite is the new, extremely simple and intuitive programming software for implementing non-networked solutions with SIMATIC S7-300, SIMATIC C7, ET 200S (IM 151/CPU and IM 151/CPU FO) and ET 200X (BM 147/CPU). STEP 7 Lite has been structured such that it is extremely easy to learn within a short time and provides users with optimum support in every phase of a project. Projects produced using STEP 7 Lite can be used further with STEP 7/STEP 7 Professional.

STEP 7 Lite includes user-friendly functions for all phases of an automation project:

• Hardware configuration and parameterization.
• Programming.
• Testing, commissioning and service.
• Documentation.
• Operating/diagnostics functions.

All functions are supported by a powerful, multi-stage online help system at all times.

Communication between automation systems and the use of CP and FM modules are not supported by STEP 7 Lite. It is necessary to use STEP 7 or STEP 7 Professional in such cases.

Optional packages are available for STEP 7 Lite:

• S7-PLCSIM:
  The S7-PLCSIM simulation software permits functional testing of the created SIMATIC S7 user blocks on a PG/PC, without the target hardware having to be available. Thus the detection and elimination of programming errors are transferred to an early phase of the development. This means:
  • Faster initial commissioning at lower cost.
  • Increase in program quality.
• TeleService:
  TeleService allows remote maintenance of SIMATIC S7/C7 automation systems using a PG/PC over a hardwired or radio network. Users can apply the known functionalities of STEP 7 and the engineering tools, comparable with a local MPI connection. TeleService increases the effective availability of plants and machines. Access with TeleService means that technical services (e.g. maintenance, updating or fault analysis) can be carried out cost-effectively from a central service point.

Other SIMATIC software packages, e.g. engineering tools, cannot be used with STEP 7 Lite.

STEP 7 Lite is available as a software package for PC installation. A PC adapter, CP 5511, CP 5512 or CP 5611 is required for use with a PC.
