A few marks from my side...
It is not possible to do all changes in run. If you have PCS7 8.1 with firmware v8.1 (of the CPU410), you can download block types changes in run except for: - Changing a default signal IO (such as changing a BOOL from 0 to 1) - Change a signal name which is used for messages (used in the messageID) As of PCS7 8.2, the default IO can also be downloaded in run, but changing a signal name still requires the CPU410 to go to stop.
And the SEC can be expanded by 100 or 500 PO at a time. Not just only by 100. The maximum amount of PO is 2600. The main advantage what I think it's good, it that it is also scalable in terms of plant size. Since firmware v8.1, the CPU's two internal PN/IO interfaces can be used. This means you have several options to configure your plant: Option 1: Use 1 Profinet interface for the plant bus, use the other for Profinet IO (Process bus). Option 2: Use the two interfaces to design redundancy on the system bus Option 3: Use both interfaces to design redundancy at the process bus Additional to that, you can use an additional CP443-1 card, which you can use for you plant bus. In that case, you can use both PN/IO interfaces to connect 250+250 Profinet IO devices. So, you have a lot of options with the CPU410.... |

Hi all, this note is taken from the manual of the CPU S7-410: The system expansion card (SEC) is inserted in a slot at the back of the CPU. With the SEC, the CPU 410-5H is scaled according to the maximum number of loadable process objects. The CPU cannot be operated without the SEC. SECs are available with the following number of POs: ● 0 You must store the required number of POs on this SEC before the first use. ● 100 ● 500 ● 1000 ● 1600 ● 2k+ (unlimited) You can expand the number of POs without replacing the SEC. Where 2k+ is roughly equalizing 2600 PO. Regards P.S. Just had a look in teh PCS 7 manual "licenses and configuration limits" in table 5-5 it is statet that 2600 PO is the rough maximum for 410: https://support.industry.siemens.com/cs/ww/en/view/90663401 |

New question published by Branimir is split to a separate thread with the subject PCS7 V7.1, can't find PLC in HW configuration. Best regards |
