It depends on which Step 7 version are you using. Some of them got 4 connections, some of them only two connections. How to check this? Simply create an AS-AS S7 Fault-tolerant connection, double click on the connections, if you can see 4 connections (A R0-B R0, A R0 -B R1, A R1-B R0, A R1-B R1), it means you have 4 connections. If you can only see 2 connections ( A R0 - B R0, A R1 - B R1), it means, Rack 0 CPU A cannot communicate with Rack 1 CPU B. The step 7 version V5.6 HF3 has 4 connections (PCS 7 V9.0 SP1 delivered version) The step 7 version V5.6 HF4 onward, it became 2 connections. This has been confirmed by Siemens and I still have the email. If you need more information, let me know. We are still requesting the 4 connections solution right now. Hope it is helpful for you. |

Hello, Here are their reply. " I understood, that the HF3 provides the function you want. But it seems that this was not intended as system function and was changed in HF4 / HF5. If you do not need further support, I would recommend to close this SR at friday. Please let me know, if this does not match your intention. But in this case any further investigation is only possible in extended Support." And we actually triggered Siemens Singapore and our customer to trigger Siemens Germany for an answer for this. And the last result was, just accept it. 4 connections will not be available after V5.6 HF3. And our customer know it, so we skipped this test during FAT. Hope it helps you. |

I suggest you trigger a support request to Siemens as well to let them know this function is an important function. If I were the customer, I will not accept it as well. Siemens claim this as a "Multipoint" of failure. and they said their system designed for single point of failure only. |
