Hello All,

Can the ET 200SP HA achieve IO Redundancy in TIA? (with TIA > V18)

I have used ET 200SP HA in Step 7 with Simatic S7 410E already and it worked well.
But new project is asking for IO Redundancy  with 1500H. 
(I cannot use ET200SP and must use ET 200SP HA)

As per S7-1500R/H redundant system 2024 System manual  page 133
ET 200SP HA IM 155-6 PN HA (6DL1155-6AU00-0PM0), FW version V1.2 or higher
****************************************************
1. S7 1500 H and ET 200SP HA can be used simply.
But this is talking about the S7 1500H and ET 200SP HA compatibility. 

I want to confirm about the IO Redundancy works with TIA or not. 
As per below link dated back to 2020.  TIA was not supported for IO Redundancy.
Functional overview of SIMATIC ET 200SP HA in SIMATIC PCS 7, SIMATIC PCS neo, SIM... - ID: 109782701 - Industry Support Siemens

Since its 2025 TIA at V20 Any updates on this?

 

Hello All, 
Any updates on this?
My area Siemens Partner told ET 200SP HA is not supported for IO redundancy with 1500.
But the data they are referring is dated back to 2020. 
Also they have told to use the parallel wiring with diode which we used to do for ET200M as a workaround.

Please kindly guide on the same. ET 200SP HA IO redundancy with 1500.
