Hello everyone! I have got a great problem. At a plant we have two S7-417 5H which are connected to each other for redundancy function. Also, we have two independent identical WinCC work stations and they are connected via Ethernet to the PLCs. Everything was ok, but a couple weeks ago troubles have begun. Connections losses every 1-2 s between PLC and workstation with errors in file SIMATIC_S7_PROTOCOL_SUITE_02.LOG Errorcode 0xFFDF 011F. Sure, I looked in https://support.industry.siemens.com/cs/ww/en/view/109736225/7794891147 but there is no such error code. The error happens on both workstation every 1-2 s and I know that the reason is not in workstation or network but it is in PLCs because after wiping out memory in PLCs and downloading all project into PLCs everything is OK for 1-2 days then all begin again. Could someone explain me what is going on with connection between PLCs and work station, also why the full download PLCs helps to solve temporally the problem? |

Hello neurobot; re you trying to setup redundant connections of 2 WinCC stations to a S7-400H system? I believe in that case you ould need a S7-Redconnect syste, with a CP 1613 A2 in each PC station (WinCC projects( and a Hardnet-IE S7-Redconnect license in the S7. See the description of s7-Redconnect in this discussion: https://support.industry.siemens.com/tf/WW/en/posts/s7-redconnect/43959?page=0&pageSize=10 and from the Siemens Industry Mall, examine the product description (current part numbers are available in the Ordering Data tab): https://mall.industry.siemens.com/mall/en/WW/Catalog/Products/9300173?activeTab=ProductInformation Hope this helps, Daniel Chartier |

Hello Daniel! Yes, I have two redundant WinCC workstations and I established redundant connections with 417 H. In addition, sure, I have S7-Redconnect license. My system is in the same state everytime: one 417H is always a master and other is in reserve. Also, it had worked ok a couple of weeks but now the system has become faulty. Could your explain, what does it mean SIMATIC_S7_PROTOCOL_SUITE_02.LOG Errorcode 0xFFDF 011F and why the full download both PLCs helps and it works without errors 1-2 days? Thanks, Basil |

Maybe the reason that I used standart Ethernet adapters instead of CP1613 on WinCC station for a redconnection? What is the difference between CP1613 and D-link Ethernet adapter? http://www.plctalk.net/qanda/showthread.php?t=47558 I read this topic and Daniel said there that the load on the PC processor would be heavier with the different adapter. |
