What are the functions of WINCC, can it be configured, and can PCS7 replace STEP7?

There is another question, can I use step7 in pcs7 to write directly with ladder diagram or sclstl, without using the function blocks in pcs7?

The pcs7 installation software contains step7 and wincc. Step 7 Some features are not available in a typical installation and need to be installed separately. For example, CFC, SFC, SCL....

So step7 is generally for 300 CPUs. (The programming language used is usually stl, lad). If you want to use CFC or SFC, the corresponding CPU will generally be 414, 416, 417

Other models don't have enough memory.

So the key depends on what you need.

Thinking about practicality, then it depends on the size of your project. Small project step7+winccBig project PCS7. (Do you want to manually add variables to wincc for projects with tens of thousands of points?) ）

Consider**. Step7+WinCC is cheap.

Consider efficacy. PCS7, of course. (including step7 and wincc).

Are you modbus communication or profibus communication? Since you use S7 software, it is generally profibus-dp....Once the gsd file is installed, you can naturally find the one you want, which I usually do. Suggestion.

PCS7 is Siemens' DCS software, which has built-in step7 and winCC, which has many organic combinations of connection components and plug-ins. And step7+wincc is just a normal integration. All in all, PCS7 is DCS software, and STEP7+WinCC is just programming software and configuration software, which can be basically regarded as independent.

WinCC is the Windows Windows control center, is the upper computer monitoring software (configuration software) of Siemens, Step7 is the programming software of the lower computer (PLC), to put it bluntly, one is the monitoring software on the PC, and the other is the programming monitoring software of the PLC of the lower computer.

Step7 and WinCC are both industrial control software products of Siemens, the former is used for PLC programming, and the latter is human-machine interface configuration software, and the two can be used together.

The interface is different when the software is opened, in addition, there is no need to worry about which software it is, the effect is the same, you can use it, PCS7 is the product of the TIA concept, generally everything is integrated together, if you want to determine the software version, you can see it in the installed software.

PCS7 is a DCS system for process control from Siemens, which is highly integrated with STEP7 and WinCC, and integrates other related software and hardware to meet the needs of the DCS industry. PCS7 is tailored to the needs of DCS system, and the biggest difference from the separate step7 and wincc is that the PCS7 is designed to meet the needs of DCS, and the separate step7 and wincc are general-purpose configuration software.
