Dan_Tien_Shan Posts: 22 Rating: (0)	Hi. I`ll describe my problem by dividing it to some steps. Step 1. When i do connect the CPU1214c (214-1he30-0xb0) to PC with installed SW Step 7 V11 SP2+Upd2 and WinCC V11 Pro SP2+Upd2, cpu shown in acccessible devices window like "Accessible device" with device type = S7-1200, interface type - ISO(Ethernet), mac address. Step 2. Then, jump from portal view to project view. Go "Project tree" => "Online access" => "My Ethernet controller" => "Accessible device" => "Online access" => "Functions" => "Assign ip adress". Setting ip(default is 0.0.0.0) adress 192.168.1.100(for example) subnet mask 255.255.255.0 and press "Assign IP adress". Then press "Update accessible devices". Updates sucessfully. The "Accessible device" changes to "CPUcommon". Step 3. Adding CPU 1214c, in device view by clicking to the Ethernet port on CPU board entering to a "Ethernet address" window below. Adding new subnet = PN/IE_1 then setting the IP address the same as set in accessible devices window(192.168.1.100) Clicking to CPU board, then click to "Go online" Step 4. In "Go online" window the CPU is shown as "CPUcommon" (with right device type! = CPU 1214C) Clicking "Go online" button below. Result : No connection with PLC. There is message below "Connection to PLC_1 terminated", in device information message "Establish new online connection". My actions to solve this problem: 1. Read threads with similar problem First thread /tf/WW/en/Posts/67709 second /tf/WW/en/Posts/63240 2. Reset the CPU to factory settings with reset of ip adress and without it. 3. Setting up the another ip adress of CPU 4. REINSTALL Step7 V11 and WinC too 5. Swithced off the Antivirus(Symantec Endpoint Protection 12.0) and Brandmauer. 6. Changed the CPU to same. 7. Checked to installed Ethernet interfaces 8. Changed the interface in "PG/PC interface" There are 3 ethernet interfaces: a. My eth card ISO b. my eth card tcp/ip c. my eth card auto Tryed with each of them with testing. I dont know how solve this problem. Maybe something doing wrong. Thanks for helping me.

Not much I can suggest, but as long as it is commong problem with no particular solution, maybe Siemens support is aware of that and can help ? You could try to open support case. By the way, I suppose you use latest firmware fo the PLC ? Didi you updated firmware ? Maybe by mistake you uploaded wrong firmware (not sure if PLC will accept wrong firmware).

Dan_Tien_Shan Posts: 22 Rating: (0)	Did the support request. The problem probably about firmware. But, the firmware version is 2.2.0 ! Checked at Online & diagnostics - >Diagnostics -> General. The cpu1214c becomes"CPUcommon" when changing his default address from 0.0.0.0 to another(don`t matter which). Month ago i`ve connected the plc`s 1212cand 1214c and there was no problem ! Maybe SP2+Upd2 that i`ve installed is the occation. Will wait to Support service answer.

Solved the problem by downgrading a firmware version vrom 2.2.0 to 2.1.2. May close

Adam24 Posts: 13 Rating: (2)	Hi everyone! I had the same problem with 2 CPUs and I finaly find a solution: (I do not talk about here the configuration of IP, you don't need to do anything special) You have to have the right hardware config! You have to be OFFLINE! (If the GO OFFLINE icon is active, then click on it) Right click on the CPU name (or on the CPU in the device view), then COMPILE - ALL! Right click again on the CPU and then DOWLOAD TO DEVICE - HARDWARE CONFIGURATIUON! After these steps you should be able to go ONLINE, and use the PLC as any otherones.
