Dear All.. Please See Attached Network Layout.The System Has Hot Standby PLC System With S7 400H PLCs. Also There Are 5 RTUs On The Right Side.I Wanted To Use ET200S CPU As An RTU But Now I Am Informed That The RTUs Should Also Be In Hot Standby.So My Question Is How Can I Achieve Redundancy In RTU. 1.Should I Go For Again S7 400 H PLCs AsRTUs.As I Think Hot Standby Can Be Achieved By S7 400 H Only. Please Advise Thanks Attachment15W10_Architecture.pdf (219 Downloads) |

Hello rahilansari; Have a look at how another member of the forum, hnc, has uses Profibus-DP, OLMs and redundant ET200Ms to design a system similar to what your client is asking for: /tf/WW/en/Posts/51292 With the active backplane required for the redundant ET 200Ms, you can configure hot-swappable IOs on top of redundancy. Hope this helps, Daniel Chartier |
