Important differences between PCS7 and STEP7+WINCC
Thread Content
PCS7 is a DCS, while STEP7+WINCC is a PLC; both use the S7-400 CPU for their hardware. What are the differences between the two in terms of the number of hardware components they support?
Basically the same, but they use a unified data platform
But when programming PCS7, the number of function blocks that can be used, in other words the capacity to utilize hardware points, is limited, right?
sTEP7 is a configuration and programming software for Siemens S7-300/400. It can only perform the functions of basic automation, corresponding to the field level and workshop level of control systems. PCS7=STEP7+WinCC+various tool software. PCS7 is a highly integrated software suite developed based on Siemens’ TIA concept; it combines together the various software applications that may be needed in engineering projects, thereby offering more powerful and comprehensive functions. PCS7 can perform functions for basic automation and process automation, corresponding to the field level, plant level, and management level of control systems. If we also take into account his requirements for the CPU, then PCS7 is a DCS designed for process control, with much more powerful functions. Only CPUs above 414 can be PCs7
I am currently using S7+Wcc V7
PCS7 process control: different projects are organically integrated and can call on each other for management. STEP7 + WINCC is primarily designed for one project; when it comes to just one project, there isn’t much difference apart from adding asset management software to PCS7.
What was said upstairs makes a lot of sense. In terms of details, PCS 7 has more powerful functions; programming in PCS 7 mainly involves charts, while in Step7 blocks are typically used. WinCC allows for segmentation based on the hierarchy of the factory. Anyway, after using PCS 7, I found it to be more user-friendly than Step 7.
They falsely say that I also use PCs for 300 PLCs
