STEP 7 (PLC Classic Software)

STEP 7 (PLC Classic Software)



On first name terms with the hardware

The new SIMATIC automation platform covers everything that you need for automation today: programmable logic controllers covering a wide range of performance, complete units, in which the operator panel is already included, PC-based control, external control and monitoring solutions and communication networks.

All of this under a single user interface, without any interface problems, as a fully integrated complete solution.

This removes barriers that have until now cost companies a lot of money: the barrier between PLC and the computer world, the barrier between process engineering and production technology – and even the barrier between standard software and automation software.

This brings us right to the topic. Because the basis of all these advantages is the software. And the foundation of this software system is STEP 7, of which there are two types: for users who only use a part of the SIMATIC automation platform as hardware (and therefore do not need the full spectrum) and for those who use the full range.

The following applies to all versions: they ensure that users are on familiar terms with their hardware!
