Well the first thing you have to do is to go online with the PLC if you want to backup the program.
What interface are you using between the programming computer and the CPU?
How is your PG/PC interface setup?
Hope this helps,
Hi daniel, thanks for answer,
1)already connected online with the PLC, and i selected Accessible Nodes and show me the Accessible Nodes but don't show me the cpu.
2)I am using the SIMATIC S7 PC Adapter USB.
3)My PG/PC Interface Setup is PC Adapter (Auto).
I connect online with de PLC, but only show me the accessible nodes, and i'm trying the backup the plc, if you can tell me the steps for execute the backup and later view the cpu and components. I would appreciate.
Complete procdure of download from a S7 controller
is previously explained here:
please follow these steps:
1- create a new project
2- select the newly created project and in SIMATIC
Manager PLC----> Upload station to PG
3-Wait till all blocks uploaded into offline data base
My notes on how to do it successfully:
1- Be sure that target CPU is supported by the version
of STEP7 you are using.Update the hardware catalog
2-If you are using PC adapter in "Select Node Address"
Window, press"view" button to see all MPI networked
(or Ethernet in case of using CP) CPUs and select
