S7-1500 Backplane

Dear All,

My employer insists on using a S7-1500 CPUs on a new project.

I want a Solution to use Hot Swap feature (by Active Backplane or any other way) without using the ET200MP (In order to reduce project costs).

If I doesn't use a ET200, I cant have the benefits of Hot Swap?

Hello MHMD.S;

For the S7-1500 family of CPUs, Siemens proposes a redundancy solution based on the S7-1500H or S7-1500R as high-availability CPUs. You can start with a presentation of these products here:

https://www.siemens.com/global/en/products/automation/systems/industrial/plc/simatic-s7-1500/redundant-and-high-availability-cpus.html

The S7-1500R CPUs use a Profinet link to communicate between the redundant CPUs, with a fail-over time of 300 ms, while the S7-1500H use a fiber-optic connection between them, with a fail-over time of around 50 ms. 

In both cases you will need to use remote I/O systems over Profinet line/ring (ET200M Pand/or ET200SP) , there will be no backplane connection for the I/O modules directly on the CPUs.

For more details, you also have access to the S7-1500R/H system manual here:

Hope this helps,

If you do not require redundancy and simply want to swap failed modules without powering everything down, the vast majority of s7-1500 modules are hot-swappable.

Check the s7-1500 system manual for a complete list of hot-swappable and non-hot-swappable modules.  After you have that, you can decide if that meets your new project's needs.

I think you will find it likely does.

Power Supply modules cannot be hot-swapped.  Here's an older FAQ on the subject:

Thank dear dchartier for your guidance.

I don't need any redundancy other than "Power supply Module"(PM).

my question is that can I connect a single CPU to "IO module cards" with "active back plane" (to information connection) without the need to ET-200

Or I have to use "U type Connectors" for connecting  CPU and IO module cards together on the rail.

Hello MHMD.S;

Sorry I misunderstood your question earlier.

This document from SIOS provides the information you wanted, snd confirms the information from O.Einstein: for IO module hotswap on a S7-1500 system, you will need an ET 200 M (with active bus modules for max. 2 slots), a ET 200S  an ET 200 MP (with active bus modules for 4 or 12 slos), or an ET 200SP.

For information on redundant power supplies for the S7-1500, this discussion could provide guidance on SITOP units:
