Hello to all, i have a question about CPU410 5h and the new Process Object concepts.

My customer have a PCS7 system composed by a 7 PLC's .  Some plc are old ( cpu 416 3d ) and some Plc's are more recent.

We need to add a new part of plant and we need to add a new plc. Our choice is the CPU 410 5h, but

I don't know the concept of Process objects.

Does the cpu already have a certain amount of POs by default?  If Yes how many ?

I know that there is a "chip"  in the rear of the cpu for the PO extension. This Chip is supplyed is

supplied together whit the cpu ?  

Thank you in advance

Fabio

Hello Fabio;

I can suggest you start by looking at the concept of Process Objects in your version of PCS7. The documents beliw also explain how POs are "booked" for the AS in the system.

In this link, open the "Chapter" column corresponding to the version of PCS 7 you are working with:

One you have clarified the basic concepts related to POs, we can try to answer specific issues you have. have

Hope this helps,

Hi fabioga66,

in addition to the post of Oreca, if you buy a new CPU 410-5H with a SEC then you can load the CPU with 100 AS PO without upgrade the SEC. If you need more, you can update the POs.

Note:
Please consider that the 410-5H has a special limitation. It's only allowed to load the CPU from the CFC/SFC-Editor, HW-Config or with the assistant "Compile & Download" and not any more from the SIMATIC Manager or from the SCL-Editor.

But with the 410-5H you can also load the a Type change of a block in Run. that means you can change the interface of a block (add a new input) and load this block without to stop the plant.

With regards
Heisenberg
