As attached files our system consist of two redundant CPU S7-412 H, 2 SCALANCE XC206-2 Switches (6GK5206-2BB00-2AC2) and one HMI TP 1500 Comfort, The system connect to DCS through 2 redundant fiber optic cable. The redundant of HMI was working very well but after connect the DCS fiber optic cables to the switches the HMI become slow in show Feed back and receive order, also the DCS System Engineer inform us that our system make conflict at DCS system. So now we removed one ethernet cable of two cables connected to HMI then no problem in HMI (slow in Feed back) and no conflict at DCS system but now the HMI connect to CPU1 only. or We remove one of the DCS fiber optics cables to remove the problem. I follow all instruction from Siemens support in This link for establish HMI redundancy. https://support.industry.siemens.com/cs/document/96837136/connecting-simatic-hmi-panels-with-a-simatic-s7-400h-(wincc-v16-and-step-7-v5-6)?dti=0&lc=en-ZM And as I mentioned before it was working very good, but all problem happen after connect DCS. Ethernet cable was connect to HMI as per attached file X1 (P1 & P2). So I think If I separate these two ports, the problem will be solve. Some one suggest to activate Media redundancy for HMI Port but it show me that I have to use it as client and If I select Clint it show me error ( a manger must be configured ). So I add a temporary switch and made it as a manager then make HMI port X1 as MDR client, but also still the same problem. in below YouTube link I upload a recorded video Of HMI showing blinking of both tags (TRIGGER_PLC1 and TRIGGER_PLC2) First in case no connection to DCS then I will connect the DCS Then remove DCS Connection again. https://www.youtube.com/watch?v=fKdekcx81uE I tried to put all details in attached file as possible. Thanks in advance.
