siemens c7-635

Hi Does anybody know what software would be required to interigate a c7-635? and also if it is possible without having the original program?

ProTool for panel, step 7 for plc side.

Protool is obsolete and I don't think it would support the newer operator panels. You would have to use WinCC Flexible and it can integrate into Step 7 for a common tag data base, if you want.

"interigate" ?
Integrate, or interrogate, or ?
As RRobbins said you can program it with Protool or WinCC Flexible.

Since you ask about the original program I guess you want to access an existing program but dont have the source code.
For the S7 part of the C7-635 (same as a 314C-2DP) you can upload the program but it will be without comments or symbols.
For the HMI part of the C7-635 (same as an TP170B or OP170B) you cant do anything without the original source, except write a new program.
