CPU 315-2PN/DP for Software Redundancy

[cyrus 0]

Hi Dears,

I have 2 No. CPU 315-2PN/DP (6ES7 315-2EH14-0AB0)

I want to use this CPUs for S7 300 Software Redundancy. I Have 2 CP342-5 too for IMs.

I want to use profibus port of this CPU for synchronization.

if this CPUs are suitable for software redundancy? or I can not use this CPU and I must to use CPU-315-2DP instead?

 

Thanks

Sorry, no help. I have never encountered Redundant S7-300's anywhere. Not sure it was ever supported. I know S7-400's were/still are supported, but they use special redundancy modules mounted on the CPU's.

In the PCS7 world, you have to start your project as redundant, you cannot "convert" an existing simplex system to duplex controllers. 

You can do a simple experiment, in Simatic manager, see if you can start a new redundant project with S7-300 controllers.
