Hello to all, Does anybody know the maximum IO quantity capacity of AS 410 CPU? according to its manual which mentioned 7500 IO.is it real value. Regards, Moji |

Hello moji; The CPu 410-5H does not count in terms of actual I/O channels. It uses the concept of Process Object for its licensing and expansion. A Process Object (PO) is a logical impementation of I/Os and logic to control a process element; a pO ould be a motor, a pump, a control loop... and it includes all I/Os (internal and external) required to program it. See this thread for more information: To run the CPU 410-5H, you need bot PO licenses and equivalent RT license; they are designated as System Expansion Cards (SEC). The basic bundle comes with a license for 100 PO, and can go up by 100 PO up to 2000 PO, which is considered Unlimited.You can buy licenses for 500 PO, 1000 PO, 1600 PO... of course. https://mall.industry.siemens.com/mall/en/WW/Catalog/Products/10164620 Hope this helps, Daniel Chartier |

I guess it is limited by the work memory now. For a redundant CPU, the recommended work memory is less than 60%. Then it will depend on the OS single station / multi station maximum PO. |
Please give me 5 stars Rating if my post is helpful for you. :) |

Hello Daniel thanks for your answer and as you mentioned CPU AS 410 works according to PO.I wnat to know that for 2700 signals (about 2000POs),is it possible to consider only one AS-410 CPU with regarding enough SEC 2K? Is it a real value for a CPU 410 which support 2K POs (more than 2000 IO signal)? another question is that what is function of SEC and how it effects on CPU performance?

Hello; I/Os available to the CPU and POs (Porcess objects are considered differently for the CPU 410-5H. First, here is an indication of the I/O count available for this CPU, whatever license is loaded in the SEC: https://mall.industry.siemens.com/mall/en/WW/Catalog/Products/10164620?activeTab=ProductInformation CPU 410‑5H Process Automation supports…
This number never varies, it is part of the hardware capacity of the CPU. Now, since the CPU 410-5H is designed for PCS 7 projects, here is a look at AS (S& CPU) and OS (WinCC station) license count of POs: How are the licenses for the AS and OS counted in PCS 7 Each PO can be associated with any number of I/O, digital and analog, and also internal variables, depending on the project blocks used in the CFC/SFC program. The PCS 7 editor will evaluate the number of POs required when you try to connect to the CPU. If you purchase the largest SEC (2000 POs +) you are considered Unlimited and do not need any further expansion. Hope this helps, Daniel Chartier |
