I recently purchased a used machine out of Denmark that has 3 Siemens PLC's
Primary Main PLC
Simatic S5 115U CPU 944B
Secondary PLC
Simatic S5-95U
Tertiary PLC
Simatic S7 300
CPU 315-2 DP
I think I might have the connecting cables but have no idea what software I might need to connect to the PLC's or to test the cables . I'm guessing some version of Step 5 or Step 7 but not sure if Step 7 is backward compatible with the S5 PLC or I need both pieces of software. I also have no idea where to purchase said software since it seems pretty old. I will be a basic user just to log in and troubleshoot machine issues as we are the end user manufacture.
This is my first time playing with anything Siemens stuff so I really need help.
