hello,

i am not able to upload backup from the s7200

Double clicked CommunicationButton Set PG/PC interface.
Double Clicked and refreshed and  CPU type is not showing , i am getting error , pls check baurd rate, even selecting all baurd rates , still facing error ,

Split from S7-200 program backup.

Hello,

not enough infos from you, sry. What settings you have set in PG/PC interface? Click on PG/PC interface and zip screenshots from your set parameters/screens. What exactly connection/interface/adapter you have?

Hi team,

I have S7-200 PLC and CP5711 for communication. While uploading program back-up the node is getting identified but a ? is displayed at the node and I am unable to upload/download the program back-up. Kindly guide me to do so.

Microwin4.0.9.25

Hello,

sry not clear info. Your node is identified you said, so what type CPU find MicroWin? If you have ? and not clear info about used CPU, your CPU isn't identified. What exactly order number of CPU, firmware? What profile you've set to PG/PC with CP5711? You can set only Profibus, what is known to me for proper connection to S7-200 with CP5711...

Hello,

again pls read my previous sugestion, attach some zipped screenshots if you can about settings in PG/PC interface. With Profibus settings to CP5711 is expected use Universal profile to Pofibus settings, hope. Better you can also put CPU to STOP and then test connection.

Hello,

ok, try as I said before use (on 2-nd screen) Profile -> Universal, not DP. Also pls set PLC to STOP for sure. In case of not luck, try all speeds which can be selected there. What I remember, same settings I used with my PG M4 time ago with success. Pls give info after tests. If all fails, try set MPI profile.

Thank you for valuable suggestion,

actually,we have three separate s7-200 cpu's.

we tried by selecting profile as universal,one cpu got communicated successfully and uploaded backup.But couldn't able to communicate for another two same type Cpu's ,

please find the snaps of error what we got.

Appreciated your help. 

Hello,

what kind of S7-200 CPUs you have? All new family (22X versions) or also some old (21X) version? Pls try all speeds what you have there available, also check you set highest Address what can be discoverable on bus (somewhere you have only 10 so other if has 15 will be not find logically). My last hint can be connect via PB DP cable or use only PB DP connector with PG plug. Set only one resistor ON and try connect to CPUs. I expect maybe problems with old types CPUs family but also some HW problem. Hard to say...
