Functions for Every Stage of an Automation Project
STEP 7 is the standard tool for the automation systems SIMATIC S7, SIMATIC C7 and SIMATIC WinAC, providing functions that are easy to utilise at every stage of an automation project:
| Function | Description |
|---|---|
| Hardware Configuration & Parameter Assignment | Configure automation hardware and assign device parameters for SIMATIC S7, C7 and WinAC systems. |
| Communication Configuration | Define and configure communication specifics between controllers, devices and networks. |
| Coding | Programme automation logic using STEP 7's structured block-based programming model. |
| Commissioning, Servicing & Testing | Commission, test and service automation projects throughout the plant lifecycle. |
| Record-Keeping & Preservation | Maintain documentation and project archives for long-term maintainability. |
| Operating & Diagnostic Functionalities | Monitor, operate and diagnose automation systems from a unified engineering environment. |
A Note on Newer CPU Generations
The new generation of S7-1200, S7-1500 and ET 200SP CPU PLCs, as well as the S7-1500 Software Controller, must be programmed using STEP 7 (TIA Portal) engineering software. Of course, the S7-300, S7-400 and SIMATIC WinAC can also be programmed using this software.
Siemens allows you to work with both traditional engineering software and STEP 7 (TIA Portal) using a combined licence for both platforms — see "STEP 7 Professional" for additional details.
STEP 7 Function Blocks
All user programmes and the data needed to support them are stored in blocks in STEP 7. The ability to invoke subroutines or other blocks inside a block allows the user programme to be structured — this significantly improves PLC programme maintainability, transparency and clarity. The following block types are available:
| Block Type | Description |
|---|---|
| Organisation Blocks (OBs) | Manage the programme sequence. OBs are categorised into classes (such as time-controlled and alarm-controlled) with varying priorities based on the triggering event, and may interrupt each other based on priority. Comprehensive start information about the triggering event is given when an OB starts, which the user programme can evaluate. |
| Function Blocks (FBs) | Contain the actual user programme. Distinct data can be provided to function blocks for every call (an instance), kept in the designated instance data block and automatically maintained by the system, together with internal tags and results. |
| Instance Data Blocks (Instance DBs) | Allocated to a block when an FB/SFB is invoked, and automatically created during compilation. The user programme or an operator control and monitoring system can access this instance data, including symbolically. |

STEP 7 is the standard engineering software for the automation systems SIMATIC S7, SIMATIC C7 and SIMATIC WinAC, used for hardware configuration, parameter assignment, coding, commissioning, servicing, testing and diagnostics.
The new generation of S7-1200, S7-1500 and ET 200SP CPU PLCs, as well as the S7-1500 Software Controller, must be programmed using STEP 7 (TIA Portal). The S7-300, S7-400 and SIMATIC WinAC can also be programmed using this software.
STEP 7 uses Organisation Blocks (OBs) to manage the programme sequence, Function Blocks (FBs) to contain the actual user programme, and Instance Data Blocks (Instance DBs) that are automatically allocated when an FB/SFB is invoked.
Yes, Siemens allows working with both traditional engineering software and STEP 7 (TIA Portal) using a combined licence for both platforms — see "STEP 7 Professional" for details.
STEP 7 V5.7 SP2 licences are available in various language combinations, including English/Japanese, English/Chinese, and a 5-language pack (German, English, French, Spanish, Italian), depending on the MLFB ordered.
